+
+---
+
+## Introduction
+
+This document provides accessibility guidelines for developing components and features for the Base website. All new code should follow WCAG 2.2 Level AA standards at minimum.
+
+### Why Accessibility Matters
+- **13% of global population** has some form of disability
+- Legal requirements (ADA, Section 508, AODA, etc.)
+- Better UX for everyone (keyboard users, mobile, low bandwidth)
+- SEO benefits
+- Brand reputation
+
+---
+
+## WCAG Compliance
+
+### Levels of Conformance
+- **Level A** (Minimum): Basic accessibility - REQUIRED
+- **Level AA** (Recommended): Enhanced accessibility - TARGET
+- **Level AAA** (Optimal): Maximum accessibility - NICE TO HAVE
+
+### Key Success Criteria
+
+#### Perceivable
+- **1.1.1 Non-text Content** (A): All images must have alt text
+- **1.3.1 Info and Relationships** (A): Use semantic HTML
+- **1.4.3 Contrast (Minimum)** (AA): 4.5:1 for normal text, 3:1 for large text
+- **1.4.4 Resize Text** (AA): Support 200% zoom without loss of functionality
+
+#### Operable
+- **2.1.1 Keyboard** (A): All functionality available via keyboard
+- **2.4.1 Bypass Blocks** (A): Provide skip links
+- **2.4.3 Focus Order** (A): Logical tab order
+- **2.4.7 Focus Visible** (AA): Clear focus indicators
+- **2.5.8 Target Size** (AA): Minimum 44x44px touch targets
+
+#### Understandable
+- **3.1.1 Language of Page** (A): Declare language with `lang` attribute
+- **3.2.1 On Focus** (A): No context changes on focus
+- **3.3.1 Error Identification** (A): Clear error messages
+- **3.3.2 Labels or Instructions** (A): Provide labels for inputs
+
+#### Robust
+- **4.1.2 Name, Role, Value** (A): Proper ARIA attributes
+- **4.1.3 Status Messages** (AA): Announce dynamic content changes
+
+---
+
+## Component Patterns
+
+### Buttons
+
+```tsx
+// ✅ Good: Accessible button with all states
+<Button
+  onClick={handleClick}
+  disabled={isDisabled}
+  isLoading={isLoading}
+  aria-label="Optional descriptive label"
+>
+  Click me
+</Button>
+
+// ❌ Bad: Div used as button
+<div onClick={handleClick}>Click me</div>
+
+// ❌ Bad: Button without accessible loading state
+<button disabled={isLoading}>
+  {isLoading ? <Icon name="spinner" /> : 'Submit'}
+</button>
+```
+
+#### Requirements
+- Use `<button>` element or `role="button"`
+- Include `type="button"` (or "submit"/"reset")
+- Add `aria-busy` when loading
+- Include `aria-disabled` for disabled state
+- Provide `aria-label` if text isn't descriptive
+
+### Links
+
+```tsx
+// ✅ Good: Descriptive link text
+<a href="/docs">Read the documentation</a>
+
+// ✅ Good: Context provided via VisuallyHidden
+<a href="/docs">
+  Learn more
+  <VisuallyHidden>about Base documentation</VisuallyHidden>
+</a>
+
+// ❌ Bad: Generic link text
+<a href="/docs">Click here</a>
+```
+
+### Forms
+
+```tsx
+// ✅ Good: Properly labeled input with error handling
+<div>
+  <label htmlFor="email">Email address</label>
+  <input
+    id="email"
+    type="email"
+    aria-required="true"
+    aria-invalid={hasError}
+    aria-describedby={hasError ? "email-error" : undefined}
+  />
+  {hasError && (
+    <span id="email-error" role="alert">
+      Please enter a valid email address
+    </span>
+  )}
+</div>
+
+// ❌ Bad: Input without label
+<input type="email" placeholder="Email" />
+
+// ❌ Bad: Error not associated with input
+<input type="email" />
+<span>Error: Invalid email</span>
+```
+
+### Modals/Dialogs
+
+```tsx
+// ✅ Good: Using Radix UI Dialog (recommended)
+import * as Dialog from '@radix-ui/react-dialog';
+
+<Dialog.Root>
+  <Dialog.Trigger>Open modal</Dialog.Trigger>
+  <Dialog.Portal>
+    <Dialog.Overlay />
+    <Dialog.Content aria-describedby="dialog-description">
+      <Dialog.Title>Modal Title</Dialog.Title>
+      <Dialog.Description id="dialog-description">
+        Modal description text
+      </Dialog.Description>
+      <Dialog.Close>Close</Dialog.Close>
+    </Dialog.Content>
+  </Dialog.Portal>
+</Dialog.Root>
+```
+
+#### Modal Requirements
+- Focus trap when open
+- Return focus on close
+- Escape key to close
+- `role="dialog"` and `aria-modal="true"`
+- `aria-labelledby` pointing to title
+- `aria-describedby` for description
+
+### Loading States
+
+```tsx
+// ✅ Good: Accessible loading indicator
+<div role="status" aria-label="Loading data">
+  <Icon name="spinner" aria-hidden="true" />
+</div>
+
+// ✅ Good: Live region for status updates
+<LiveRegion>
+  {isLoading && "Loading..."}
+  {isSuccess && "Data loaded successfully"}
+</LiveRegion>
+
+// ❌ Bad: No screen reader announcement
+<Icon name="spinner" />
+```
+
+### Images
+
+```tsx
+// ✅ Good: Descriptive alt text
+<Image
+  src="/logo.png"
+  alt="Base - Ethereum L2 blockchain"
+/>
+
+// ✅ Good: Decorative image
+<Image
+  src="/background.png"
+  alt=""
+  aria-hidden="true"
+/>
+
+// ❌ Bad: Missing alt attribute
+<Image src="/logo.png" />
+
+// ❌ Bad: Redundant alt text
+<Image src="/logo.png" alt="logo.png image" />
+```
+
+### Live Regions
+
+```tsx
+// For non-critical updates (default)
+<LiveRegion>
+  {copySuccess && "Address copied to clipboard"}
+</LiveRegion>
+
+// For critical/urgent updates
+<LiveRegion assertive>
+  {error && "Error: Transaction failed"}
+</LiveRegion>
+```
+
+### Skip Links
+
+Already implemented globally in `layout.tsx`. Add landmark roles to your pages:
+
+```tsx
+<div id="main-content" role="main" tabIndex={-1}>
+  {/* Main content */}
+</div>
+
+<nav id="navigation" aria-label="Main navigation">
+  {/* Navigation */}
+</nav>
+```
+
+---
+
+## Testing
+
+### Manual Testing Checklist
+
+#### Keyboard Navigation
+- [ ] Tab through all interactive elements
+- [ ] Verify tab order is logical
+- [ ] Shift+Tab works correctly
+- [ ] Enter/Space activates buttons and links
+- [ ] Escape closes modals
+- [ ] Arrow keys work in custom widgets (if applicable)
+- [ ] No keyboard traps
+
+#### Screen Reader Testing
+- [ ] Test with NVDA (Windows - free)
+- [ ] Test with JAWS (Windows - trial available)
+- [ ] Test with VoiceOver (macOS/iOS - built-in)
+- [ ] All content announced correctly
+- [ ] Form labels announced
+- [ ] Error messages announced
+- [ ] Loading states announced
+- [ ] Modal focus behavior correct
+
+#### Visual Testing
+- [ ] Check color contrast with browser devtools
+- [ ] Test at 200% zoom
+- [ ] Test in high contrast mode
+- [ ] Check focus indicators are visible
+- [ ] Verify no text truncation at 200% zoom
+
+### Automated Testing
+
+#### Unit Tests (Jest + jest-axe)
+
+```tsx
+import { render } from '@testing-library/react';
+import { axe, toHaveNoViolations } from 'jest-axe';
+import { MyComponent } from './MyComponent';
+
+expect.extend(toHaveNoViolations);
+
+it('should not have a11y violations', async () => {
+  const { container } = render(<MyComponent />);
+  const results = await axe(container);
+  expect(results).toHaveNoViolations();
+});
+```
+
+#### E2E Tests (Playwright + axe-core)
+
+```ts
+import { test, expect } from '@playwright/test';
+import AxeBuilder from '@axe-core/playwright';
+
+test('should not have a11y violations', async ({ page }) => {
+  await page.goto('/');
+  const results = await new AxeBuilder({ page }).analyze();
+  expect(results.violations).toEqual([]);
+});
+```
+
+#### Running Tests
+
+```bash
+# Unit tests
+yarn test
+
+# E2E accessibility tests
+yarn test:e2e accessibility.spec.ts
+
+# E2E with UI
+yarn test:e2e:ui accessibility.spec.ts
+```
+
+### Browser DevTools
+
+1. **Chrome DevTools**
+   - Lighthouse Accessibility Audit
+   - Inspect Element > Accessibility panel
+
+2. **axe DevTools Extension**
+   - Install: https://www.deque.com/axe/devtools/
+   - Run full page scan
+   - Review violations by severity
+
+3. **WAVE Extension**
+   - Install: https://wave.webaim.org/extension/
+   - Visual feedback for a11y issues
+
+---
+
+## Common Pitfalls
+
+### 1. Div/Span as Interactive Elements
+
+```tsx
+// ❌ Bad
+<div onClick={handleClick}>Click me</div>
+
+// ✅ Good
+<button type="button" onClick={handleClick}>
+  Click me
+</button>
+```
+
+### 2. Missing Focus Management in Modals
+
+```tsx
+// ❌ Bad: No focus management
+function Modal({ isOpen, onClose, children }) {
+  if (!isOpen) return null;
+  return <div>{children}</div>;
+}
+
+// ✅ Good: Use Radix UI or implement focus trap
+import * as Dialog from '@radix-ui/react-dialog';
+// Radix handles focus automatically
+```
+
+### 3. Icon-Only Buttons
+
+```tsx
+// ❌ Bad
+<button>
+  <Icon name="close" />
+</button>
+
+// ✅ Good
+<button aria-label="Close dialog">
+  <Icon name="close" aria-hidden="true" />
+</button>
+```
+
+### 4. Insufficient Color Contrast
+
+```tsx
+// ❌ Bad: Light gray on white (2:1)
+className="text-gray-300 bg-white"
+
+// ✅ Good: Dark text on white (7:1)
+className="text-gray-800 bg-white"
+```
+
+### 5. Form Inputs Without Labels
+
+```tsx
+// ❌ Bad
+<input placeholder="Search" />
+
+// ✅ Good
+<>
+  <label htmlFor="search">Search</label>
+  <input id="search" placeholder="Search" />
+</>
+
+// ✅ Also Good (if label is visually redundant)
+<input aria-label="Search" placeholder="Search" />
+```
+
+### 6. Non-Descriptive Link Text
+
+```tsx
+// ❌ Bad
+<a href="/docs">Click here</a>
+
+// ✅ Good
+<a href="/docs">View documentation</a>
+```
+
+### 7. Missing Loading State Announcements
+
+```tsx
+// ❌ Bad
+{isLoading && <Spinner />}
+
+// ✅ Good
+{isLoading && (
+  <div role="status" aria-label="Loading">
+    <Spinner aria-hidden="true" />
+  </div>
+)}
+```
+
+### 8. Animations Without Reduced Motion Support
+
+```css
+/* ❌ Bad */
+.animated {
+  animation: spin 1s infinite;
+}
+
+/* ✅ Good */
+.animated {
+  animation: spin 1s infinite;
+}
+
+@media (prefers-reduced-motion: reduce) {
+  .animated {
+    animation: none;
+  }
+}
+```

+# Accessibility Audit Report - Base Website
+
+**Audit Date**: 2026-01-04
+**Auditor**: Accessibility Specialist
+**Standard**: WCAG 2.2 Level AA/AAA
+**Repository**: base/web (base.org)
+
+---
+
+## Executive Summary
+
+This report documents accessibility issues found during a comprehensive audit of the Base website (base.org). Issues are categorized by severity and mapped to specific WCAG 2.2 success criteria.
+
+### Severity Levels
+- **Critical**: Prevents access to key functionality (WCAG Level A)
+- **High**: Significantly impairs user experience (WCAG Level AA)
+- **Medium**: Creates barriers but has workarounds (WCAG Level AA)
+- **Low**: Minor issues or AAA enhancements
+
+### Overview
+
+| Severity | Count | Status |
+|----------|-------|--------|
+| Critical | 4 | 🔴 Open |
+| High | 8 | 🔴 Open |
+| Medium | 6 | 🔴 Open |
+| Low | 3 | 🔴 Open |
+| **Total** | **21** | |
+
+---
+
+## Critical Issues (Level A)
+
+### 1. Missing ARIA Labels on Loading States
+
+**File**: `apps/web/src/components/Button/Button.tsx`
+**Lines**: 75-79
+**WCAG Criterion**: 1.1.1 Non-text Content (Level A), 4.1.2 Name, Role, Value (Level A)
+
+#### Issue
+Loading spinner lacks accessible name, making it invisible to screen readers.
+
+```tsx
+// ❌ Current Implementation (Lines 75-79)
+{isLoading ? (
+  <span className="flex justify-center">
+    <Icon name="spinner" color="currentColor" />
+  </span>
+) : (
+  children
+)}
+```
+
+#### User Impact
+- Screen reader users don't know the button is in a loading state
+- No indication that action is being processed
+- Confusion about whether interaction was successful
+
+#### How to Reproduce
+1. Trigger a button with `isLoading={true}`
+2. Navigate with screen reader (NVDA/JAWS)
+3. Observe: No announcement of loading state
+
+#### Recommended Fix
+```tsx
+// ✅ Improved Implementation
+{isLoading ? (
+  <span className="flex justify-center" aria-label="Loading" role="status">
+    <Icon name="spinner" color="currentColor" aria-hidden="true" />
+  </span>
+) : (
+  children
+)}
+```
+
+**Additional**: Add `aria-busy="true"` to button when loading.
+
+---
+
+### 2. Missing Disabled State Announcements

+**File**: `apps/web/src/components/Button/Button.tsx`
+**Line**: 74
+**WCAG Criterion**: 4.1.2 Name, Role, Value (Level A)
+
+#### Issue
+Disabled buttons use visual-only indicators. While `disabled` attribute is present, additional ARIA attributes improve screen reader support.
+
+```tsx
+// ❌ Current Implementation (Line 74)
+<button {...props} type="button" className={buttonClasses} disabled={disabled}>
+```
+
+#### User Impact
+- Some screen readers may not consistently announce disabled state
+- Visual-only opacity doesn't help non-visual users
+
+#### Recommended Fix
+```tsx
+// ✅ Improved Implementation
+<button
+  {...props}
+  type="button"
+  className={buttonClasses}
+  disabled={disabled}
+  aria-disabled={disabled || isLoading}
+  aria-busy={isLoading}
+>
+```
+
+---
+
+### 3. Clickable Element Without Keyboard Support
+
+**File**: `apps/web/src/components/ConnectWalletButton/ConnectWalletButton.tsx`
+**Line**: 151
+**WCAG Criterion**: 2.1.1 Keyboard (Level A), 2.1.3 Keyboard (No Exception) (Level AAA)
+
+#### Issue
+`<Name>` component with `onClick` may not be keyboard accessible.
+
+```tsx
+// ❌ Current Implementation (Line 151)
+<Name
+  onClick={copyAddress}
+  chain={basenameChain}
+  className="cursor-pointer font-display transition-all hover:opacity-65"
+/>
+```
+
+#### User Impact
+- Keyboard-only users cannot copy address
+- Violates fundamental keyboard accessibility
+
+#### How to Reproduce
+1. Tab through wallet dropdown
+2. Try to activate copy function with Enter/Space
+3. Observe: May not work if Name isn't a proper interactive element
+
+#### Recommended Fix
+```tsx
+// ✅ Improved Implementation
+<button
+  onClick={copyAddress}
+  className="cursor-pointer font-display transition-all hover:opacity-65 bg-transparent border-none p-0 text-left"
+  aria-label="Copy wallet address"
+>
+  <Name chain={basenameChain} />
+</button>
+```
+
+---
+
+### 4. Missing Alternative Text Context
+
+**File**: `apps/web/src/components/Builders/MiniKit/HeaderAnimation.tsx`
+**Lines**: 41, 46, 49, 52
+**WCAG Criterion**: 1.1.1 Non-text Content (Level A)
+
+#### Issue
+Images have generic alt text that doesn't convey context or purpose.
+
+```tsx
+// ❌ Current Implementation
+<Image src={minikit2} alt="minikit2" width={32} height={32} />
+<Image src={walletLogo} alt="walletLogo" width={32} height={32} />
+<Image src={farcaster} alt="farcaster" width={32} height={32} />
+<Image src={plus} alt="plus" width={32} height={32} />
+```
+
+#### User Impact
+- Screen reader users hear "minikit2 image" instead of meaningful description
+- Decorative vs functional distinction unclear
+
+#### Recommended Fix
+```tsx
+// ✅ Improved Implementation
+<Image src={minikit2} alt="MiniKit SDK integration" width={32} height={32} />
+<Image src={walletLogo} alt="Wallet connection" width={32} height={32} />
+<Image src={farcaster} alt="Farcaster social integration" width={32} height={32} />
+<Image src={plus} alt="Additional integrations" width={32} height={32} />
+```
+
+Or if purely decorative:
+```tsx
+<Image src={minikit2} alt="" width={32} height={32} aria-hidden="true" />
+```
+
+---
+
+## High Severity Issues (Level AA)
+
+### 5. Missing Focus Indicators
+
+**File**: Multiple components
+**WCAG Criterion**: 2.4.7 Focus Visible (Level AA), 2.4.13 Focus Appearance (Level AAA)
+
+#### Issue
+Custom focus styles may not meet minimum contrast requirements or visibility.
+
+#### Components Affected
+- `Button.tsx` - No custom focus-visible styles
+- `ConnectWalletButton.tsx` - Generic hover states
+- All interactive elements
+
+#### User Impact
+- Keyboard users cannot see where focus is
+- Violates WCAG AA minimum
+
+#### Recommended Fix
+Add to `globals.css`:
+```css
+/* Enhanced focus indicators */
+*:focus-visible {
+  outline: 2px solid #0052FF; /* Base blue */
+  outline-offset: 2px;
+  border-radius: 4px;
+}
+
+/* High contrast mode support */
+@media (prefers-contrast: high) {
+  *:focus-visible {
+    outline-width: 3px;
+    outline-color: currentColor;
+  }
+}
+```
+
+---
+
+### 6. Insufficient Color Contrast
+
+**File**: `apps/web/src/components/Button/Button.tsx`
+**Lines**: 24-27
+**WCAG Criterion**: 1.4.3 Contrast (Minimum) (Level AA), 1.4.6 Contrast (Enhanced) (Level AAA)
+
+#### Issue
+Some button variants may not meet 4.5:1 contrast ratio.
+
+```tsx
+// ⚠️ Needs Verification
+[ButtonVariants.Secondary]:
+  'text-white bg-transparent border border-white hover:bg-translucent-100',
+[ButtonVariants.Gray]:
+  'text-black bg-[#EEF0F3] hover:bg-[#EEF0F3]/60',
+```
+
+#### User Impact
+- Low vision users cannot read button text
+- Affects users with color blindness
+
+#### Testing Required
+- Test against backgrounds using contrast checker
+- Verify translucent colors meet requirements
+- Check hover/focus states
+
+#### Recommended Action
+1. Run automated contrast testing
+2. Adjust colors to meet 4.5:1 minimum
+3. Aim for 7:1 (AAA) where possible
+
+---
+
+### 7. Missing Form Labels and Error Handling
+
+**Location**: Search/Input components
+**WCAG Criterion**: 3.3.2 Labels or Instructions (Level A), 3.3.3 Error Suggestion (Level AA)
+
+#### Issue
+Need to audit form components for proper labeling and error messaging.
+
+#### Required Checks
+- [ ] All inputs have associated `<label>` or `aria-label`
+- [ ] Error messages use `aria-invalid` and `aria-describedby`
+- [ ] Required fields marked with `aria-required`
+- [ ] Instructions provided before input
+
+---
+
+### 8. Missing Skip Links
+
+**Location**: Main layout/navigation
+**WCAG Criterion**: 2.4.1 Bypass Blocks (Level A)
+
+#### Issue
+No skip navigation link detected for keyboard users.
+
+#### User Impact
+- Keyboard users must tab through entire navigation each page
+- Severely impacts efficiency
+
+#### Recommended Implementation
+```tsx
+// Add to layout component
+<a href="#main-content" className="skip-link">
+  Skip to main content
+</a>
+
+// CSS
+.skip-link {
+  position: absolute;
+  top: -40px;
+  left: 0;
+  background: #0052FF;
+  color: white;
+  padding: 8px;
+  text-decoration: none;
+  z-index: 100;
+}
+
+.skip-link:focus {
+  top: 0;
+}
+```
+
+---
+
+### 9. Insufficient Touch Target Sizes
+
+**File**: Multiple components
+**WCAG Criterion**: 2.5.8 Target Size (Minimum) (Level AAA, upgraded to AA in 2.2)
+
+#### Issue
+Interactive elements may not meet 44x44px minimum.
+
+#### Components to Check
+- Icon buttons
+- Close buttons in modals
+- Mobile navigation items
+
+#### Recommended Fix
+```tsx
+// Ensure minimum touch target
+className="min-h-[44px] min-w-[44px] flex items-center justify-center"
+```
+
+---
+
+### 10. Missing Live Region Announcements
+
+**Location**: Dynamic content updates
+**WCAG Criterion**: 4.1.3 Status Messages (Level AA)
+
+#### Issue
+Status changes (wallet connected, copy success, etc.) not announced.
+
+#### Recommended Implementation
+```tsx
+// Add VisuallyHidden component
+export function VisuallyHidden({ children }: { children: ReactNode }) {
+  return (
+    <span className="sr-only">
+      {children}
+    </span>
+  );
+}
+
+// Usage for announcements
+<div role="status" aria-live="polite" aria-atomic="true">
+  <VisuallyHidden>{statusMessage}</VisuallyHidden>
+</div>
+```
+
+---
+
+### 11. Modal Focus Trap Issues
+
+**Files**: Modal components
+**WCAG Criterion**: 2.4.3 Focus Order (Level A)
+
+#### Issue
+Modals need proper focus management:
+- Focus trap when open
+- Return focus on close
+- Escape key handler
+
+#### Recommended Pattern
+```tsx
+// Using radix-ui Dialog (already in dependencies)
+import * as Dialog from '@radix-ui/react-dialog';
+
+// Benefits:
+// ✅ Automatic focus trapping
+// ✅ Escape key handling
+// ✅ Focus return on close
+// ✅ Proper ARIA attributes
+```
+
+---
+
+### 12. Language Declaration
+
+**File**: Root layout
+**WCAG Criterion**: 3.1.1 Language of Page (Level A)
+
+#### Issue
+Verify `lang` attribute is set correctly.
+
+#### Required Check
+```html
+<html lang="en">
+```
+
+---
+
+## Medium Severity Issues
+
+### 13. Heading Hierarchy
+
+**Location**: Various pages
+**WCAG Criterion**: 1.3.1 Info and Relationships (Level A)
+
+#### Issue
+Verify logical heading hierarchy (h1 → h2 → h3, no skips).
+
+#### Testing Required
+- Audit with browser extension (HeadingsMap)
+- Ensure single h1 per page
+- No heading level skips
+
+---
+
+### 14. Link Purpose
+
+**Location**: Navigation and content links
+**WCAG Criterion**: 2.4.4 Link Purpose (In Context) (Level A)
+
+#### Issue
+Links like "Learn More" or "Click Here" need context.
+
+#### Recommended Pattern
+```tsx
+// ❌ Bad
+<a href="/docs">Learn More</a>
+
+// ✅ Good
+<a href="/docs">Learn More about Base Documentation</a>
+
+// ✅ Better (visually hidden context)
+<a href="/docs">
+  Learn More
+  <VisuallyHidden>about Base Documentation</VisuallyHidden>
+</a>
+```
+
+---
+
+### 15. Semantic HTML
+
+**Location**: Component structure
+**WCAG Criterion**: 4.1.1 Parsing (Level A)
+
+#### Issue
+Ensure proper semantic HTML usage.
+
+#### Checks
+- Navigation in `<nav>` with `aria-label`
+- Main content in `<main>` landmark
+- Sections use appropriate heading + landmark roles
+- Lists use `<ul>`/`<ol>` where appropriate
+
+---
+
+### 16. Motion Preferences
+
+**Location**: Animations
+**WCAG Criterion**: 2.3.3 Animation from Interactions (Level AAA, recommended AA)
+
+#### Issue
+Respect `prefers-reduced-motion`.
+
+#### Recommended Implementation
+```tsx
+// globals.css
+@media (prefers-reduced-motion: reduce) {
+  *,
+  *::before,
+  *::after {
+    animation-duration: 0.01ms !important;
+    animation-iteration-count: 1 !important;
+    transition-duration: 0.01ms !important;
+  }
+}
+```
+
+---
+
+### 17. Loading State Announcements
+
+**File**: Connect Wallet Button
+**Line**: 114
+**WCAG Criterion**: 4.1.2 Name, Role, Value (Level A)
+
+#### Issue
+```tsx
+// ❌ Current (Line 114)
+<Icon name="spinner" color="currentColor" />
+```
+
+#### Fix
+```tsx
+// ✅ Improved
+<div role="status" aria-label="Connecting wallet">
+  <Icon name="spinner" color="currentColor" aria-hidden="true" />
+</div>
+```
+
+---
+
+### 18. Error Identification
+
+**Location**: Form components
+**WCAG Criterion**: 3.3.1 Error Identification (Level A)
+
+#### Required Pattern
+```tsx
+<input
+  aria-invalid={hasError}
+  aria-describedby={hasError ? "error-msg" : undefined}
+/>
+{hasError && (
+  <span id="error-msg" role="alert">
+    {errorMessage}
+  </span>
+)}
+```
+
+---
+
+## Low Severity Issues

+
+## Introduction
+
+This document provides responsive design guidelines for developing components and features for the Base website. All new code should follow a mobile-first approach and work seamlessly across all device sizes.
+
+### Why Responsive Design Matters
+- **60%+ of web traffic** comes from mobile devices
+- Better user experience across all screen sizes
+- SEO benefits (Google mobile-first indexing)
+- Accessibility improvements
+- Future-proof design
+
+---
+
+## Breakpoint Strategy
+
+### Tailwind CSS Breakpoints
+
+```css
+/* Mobile First Approach */
+Base:      0px - 767px     /* Mobile (default, no prefix) */
+sm:        768px+          /* Tablet */
+md:        1024px+         /* Desktop */
+lg:        1440px+         /* Large Desktop */
+xl:        1920px+         /* 4K */
+2xl:       2560px+         /* Ultra-wide */
+```
+
+### Target Devices
+
+| Device | Viewport | Breakpoint |
+|--------|----------|------------|
+| iPhone SE | 375px × 667px | Base |
+| iPhone 14 Pro | 393px × 852px | Base |
+| iPad | 768px × 1024px | sm |
+| iPad Pro landscape | 1024px × 768px | md |
+| Desktop | 1440px × 900px | lg |
+| 4K Display | 2560px × 1440px | 2xl |
+
+### Container Widths
+
+```tsx
+// ✅ Use container classes with max-width
+<div className="container mx-auto max-w-7xl px-4 sm:px-6 lg:px-8">
+  {children}
+</div>
+
+// Container max-widths:
+// sm: 640px
+// md: 768px
+// lg: 1024px
+// xl: 1280px
+// 2xl: 1536px
+```
+
+---
+
+## Mobile-First Approach
+
+### Core Principle
+
+**Start with mobile styles, then progressively enhance for larger screens.**
+
+```tsx
+// ✅ Good: Mobile-first
+className="
+  text-base          // Mobile: 16px
+  sm:text-lg         // Tablet: 18px
+  lg:text-xl         // Desktop: 20px
+"
+
+// ❌ Bad: Desktop-first (requires max-width)
+className="
+  text-xl            // Everything gets 20px
+  max-md:text-lg     // Harder to maintain
+  max-sm:text-base
+"
+```
+
+### Why Mobile-First?
+
+1. **Performance**: Mobile devices load base styles first
+2. **Simplicity**: Easier to enhance than to reduce
+3. **Accessibility**: Ensures core content works everywhere
+4. **Maintenance**: Less code, clearer intent
+
+---
+
+## Component Patterns
+
+### Typography
+
+```tsx
+// ✅ Responsive headings
+<h1 className="
+  text-3xl sm:text-4xl md:text-5xl lg:text-6xl
+  font-bold
+  leading-tight sm:leading-snug md:leading-normal
+">
+  Responsive Heading
+</h1>
+
+// ✅ Body text (minimum 16px on mobile)
+<p className="
+  text-base sm:text-lg
+  leading-relaxed
+">
+  Readable text across all devices
+</p>
+
+// ❌ Bad: Hard-coded pixel values
+<h1 className="text-[80px]">Too large on mobile</h1>
+<p className="text-[10px]">Too small to read</p>
+```
+
+### Spacing
+
+```tsx
+// ✅ Responsive padding and margin
+<div className="
+  p-4 sm:p-6 md:p-8 lg:p-12
+  my-8 sm:my-12 md:my-16
+">
+  Content with appropriate spacing
+</div>
+
+// ✅ Responsive gaps
+<div className="
+  flex gap-2 sm:gap-4 md:gap-6 lg:gap-8
+">
+  Items with scaled spacing
+</div>
+
+// ❌ Bad: Fixed spacing that doesn't scale
+<div className="p-12 gap-8">
+  Too much spacing on mobile
+</div>
+```
+
+### Layout
+
+```tsx
+// ✅ Stack on mobile, row on desktop
+<div className="
+  flex flex-col sm:flex-row
+  items-stretch sm:items-center
+  gap-4 sm:gap-6
+">
+  <div>Item 1</div>
+  <div>Item 2</div>
+</div>
+
+// ✅ Responsive grid
+<div className="
+  grid grid-cols-1 sm:grid-cols-2 lg:grid-cols-3 xl:grid-cols-4
+  gap-4 sm:gap-6 md:gap-8
+">
+  {items.map(item => <Card key={item.id} {...item} />)}
+</div>
+
+// ❌ Bad: Fixed layout
+<div className="flex flex-row gap-6">
+  Breaks on mobile when items are wide
+</div>
+```
+
+### Images
+
+```tsx
+// ✅ Responsive image sizing
+<Image
+  src={logo}
+  alt="Base logo"
+  width={200}
+  height={50}
+  className="
+    w-24 h-auto sm:w-32 md:w-40 lg:w-48
+  "
+/>
+
+// ✅ Full-width responsive image
+<Image
+  src={hero}
+  alt="Hero image"
+  width={1920}
+  height={1080}
+  className="w-full h-auto max-w-full"
+/>
+
+// ✅ Aspect ratio preservation
+<div className="aspect-video w-full overflow-hidden rounded-lg">
+  <Image
+    src={thumbnail}
+    alt="Video thumbnail"
+    fill
+    className="object-cover"
+  />
+</div>
+
+// ❌ Bad: Fixed size
+<Image src={logo} alt="Logo" className="w-48 h-12" />
+```
+
+### Buttons and Touch Targets
+
+```tsx
+// ✅ Mobile-friendly touch targets (min 44x44px)
+<button className="
+  px-4 py-3 sm:px-6 sm:py-2
+  min-h-[44px] sm:min-h-0
+  text-base font-medium
+  rounded-lg
+  w-full sm:w-auto
+">
+  Mobile-friendly button
+</button>
+
+// ✅ Full-width on mobile, auto on desktop
+<Link
+  href="/docs"
+  className="
+    inline-flex items-center justify-center
+    px-6 py-3
+    min-h-[44px]
+    w-full sm:w-auto
+    text-center
+  "
+>
+  Get Started
+</Link>
+
+// ❌ Bad: Too small on mobile
+<button className="px-4 py-2">
+  Touch target too small (< 44px)
+</button>
+```
+
+### Navigation
+
+```tsx
+// ✅ Mobile menu (hamburger) + desktop menu
+<nav>
+  {/* Mobile menu button */}
+  <button
+    className="sm:hidden"
+    aria-label="Open menu"
+  >
+    <Icon name="menu" />
+  </button>
+
+  {/* Desktop navigation */}
+  <div className="hidden sm:flex gap-6">
+    {links.map(link => (
+      <Link key={link.href} href={link.href}>
+        {link.name}
+      </Link>
+    ))}
+  </div>
+</nav>
+
+// ✅ Responsive dropdown
+<div className="
+  absolute left-1/2 top-full
+  w-[95vw] max-w-[718px]
+  transform -translate-x-1/2
+">
+  Dropdown content that doesn't cause horizontal scroll
+</div>
+
+// ❌ Bad: Fixed width dropdown
+<div className="absolute left-1/2 top-full w-[718px]">
+  Causes horizontal scroll on small screens
+</div>
+```
+
+### Modals and Dialogs
+
+```tsx
+// ✅ Responsive modal using Radix UI
+<Dialog.Root>
+  <Dialog.Portal>
+    <Dialog.Overlay className="fixed inset-0 bg-black/50" />
+    <Dialog.Content className="
+      fixed left-1/2 top-1/2
+      -translate-x-1/2 -translate-y-1/2
+      w-[90vw] max-w-md sm:max-w-lg
+      max-h-[85vh]
+      overflow-y-auto
+      rounded-lg
+      p-6 sm:p-8
+    ">
+      <Dialog.Title className="text-xl sm:text-2xl">
+        Modal Title
+      </Dialog.Title>
+      <Dialog.Description className="text-sm sm:text-base">
+        Modal content
+      </Dialog.Description>
+    </Dialog.Content>
+  </Dialog.Portal>
+</Dialog.Root>
+```
+
+### Cards
+
+```tsx
+// ✅ Responsive card
+<div className="
+  rounded-lg
+  p-4 sm:p-6
+  w-full
+  max-w-sm sm:max-w-md
+">
+  <h3 className="text-lg sm:text-xl font-bold mb-2 sm:mb-4">
+    Card Title
+  </h3>
+  <p className="text-sm sm:text-base text-gray-600">
+    Card description
+  </p>
+</div>
+```
+
+---
+
+## Common Pitfalls
+
+### 1. Fixed Width Elements
+
+```tsx
+// ❌ Bad: Fixed width causes overflow
+<div className="w-[800px]">
+  Content overflows on mobile
+</div>
+
+// ✅ Good: Responsive width with max-width
+<div className="w-full max-w-[800px]">
+  Fits on all screens
+</div>
+```
+
+### 2. Hard-Coded Font Sizes
+
+```tsx
+// ❌ Bad: Hard-coded pixel values
+<h1 className="text-[80px]">Huge on mobile</h1>
+<p className="text-[10px]">Unreadable</p>
+
+// ✅ Good: Tailwind responsive utilities
+<h1 className="text-4xl sm:text-5xl lg:text-6xl">
+  Scales appropriately
+</h1>
+<p className="text-base sm:text-lg">
+  Always readable (min 16px)
+</p>
+```
+
+### 3. Excessive Padding on Mobile
+
+```tsx
+// ❌ Bad: Too much spacing on mobile
+<div className="p-24 my-32">
+  Wastes limited mobile screen space
+</div>
+
+// ✅ Good: Scaled spacing
+<div className="p-4 sm:p-8 md:p-12 lg:p-24 my-8 sm:my-16 md:my-24 lg:my-32">
+  Appropriate for each screen size
+</div>
+```
+
+### 4. Non-Responsive Images
+
+```tsx
+// ❌ Bad: Fixed image size
+<Image src={logo} alt="Logo" width={200} height={50} />
+
+// ✅ Good: Responsive image
+<Image
+  src={logo}
+  alt="Logo"
+  width={200}
+  height={50}
+  className="w-24 h-auto sm:w-32 md:w-40"
+/>
+```
+
+### 5. Touch Targets Too Small
+
+```tsx
+// ❌ Bad: Below 44x44px minimum
+<button className="px-2 py-1 text-xs">
+  Tap
+</button>
+
+// ✅ Good: Meets WCAG 2.5.8
+<button className="px-4 py-3 min-h-[44px] text-base">
+  Tap
+</button>
+```
+
+### 6. Missing Horizontal Overflow Prevention
+
+```tsx
+// ❌ Bad: Can cause horizontal scroll
+<div className="flex gap-4">
+  <div className="min-w-[300px]">Item</div>
+  <div className="min-w-[300px]">Item</div>
+  <div className="min-w-[300px]">Item</div>
+</div>
+
+// ✅ Good: Prevents overflow
+<div className="flex gap-4 overflow-x-auto max-w-full">
+  <div className="min-w-[300px] flex-shrink-0">Item</div>
+  <div className="min-w-[300px] flex-shrink-0">Item</div>
+  <div className="min-w-[300px] flex-shrink-0">Item</div>
+</div>
+
+// ✅ Better: Stack on mobile
+<div className="flex flex-col sm:flex-row gap-4">
+  <div className="w-full sm:w-auto">Item</div>
+  <div className="w-full sm:w-auto">Item</div>
+  <div className="w-full sm:w-auto">Item</div>
+</div>
+```
+
+### 7. Absolute Positioning Without Responsive Adjustments
+
+```tsx
+// ❌ Bad: Breaks on mobile
+<div className="absolute left-1/2 top-full w-[600px]">
+  Dropdown
+</div>
+
+// ✅ Good: Responsive positioning
+<div className="
+  absolute left-0 sm:left-1/2 top-full
+  w-full sm:w-auto sm:min-w-[600px] sm:max-w-[600px]
+  sm:-translate-x-1/2
+">
+  Dropdown
+</div>
+```

+## Advanced Patterns
+
+### Fluid Typography with clamp()
+
+```css
+/* For special cases where Tailwind isn't enough */
+.fluid-heading {
+  font-size: clamp(1.5rem, 3vw + 1rem, 3rem);
+  /* Min: 24px, Preferred: 3vw + 16px, Max: 48px */
+}
+```
+
+### Container Queries (Future)
+
+```tsx
+// When container queries are stable
+<div className="@container">
+  <div className="@sm:flex @md:grid">
+    Content that responds to container size
+  </div>
+</div>
+```
+
+### Responsive Utilities Helper
+
+```typescript
+// Helper for consistent responsive values
+export const responsive = {
+  padding: 'p-4 sm:p-6 md:p-8 lg:p-12',
+  gap: 'gap-2 sm:gap-4 md:gap-6',
+  text: {
+    heading: 'text-3xl sm:text-4xl md:text-5xl lg:text-6xl',
+    body: 'text-base sm:text-lg',
+    small: 'text-sm sm:text-base',
+  },
+};
+
+// Usage
+<div className={responsive.padding}>
+  <h1 className={responsive.text.heading}>Title</h1>
+</div>
+```

+# Responsive Design Issues - Base Website
+
+**Audit Date**: 2026-01-04
+**Target Devices**: Mobile (320px+), Tablet (768px+), Desktop (1024px+), Large Desktop (1440px+)
+**Framework**: Next.js 15 + Tailwind CSS
+
+---
+
+## Executive Summary

+
+### Severity Breakdown
+
+| Severity | Count | Impact |

+| **Critical** | 3 | Breaks mobile experience |
+| **High** | 6 | Significantly degrades UX |
+| **Medium** | 4 | Minor usability issues |
+| **Low** | 2 | Polish improvements |
+
+---
+
+## Target Breakpoints
+
+```css
+/* Mobile First Approach */
+Base:      320px - 767px   /* Mobile */
+sm:        768px           /* Tablet */

+
+## Critical Issues
+
+### 1. Fixed Width Dropdown Menu
+
+**File**: `apps/web/src/components/base-org/shared/TopNavigation/MenuDesktop.tsx`
+**Line**: 82
+**Breakpoint**: Mobile/Tablet
+
+#### Issue
+```tsx
+// ❌ Current (Line 82)
+<div className="absolute left-1/2 top-full w-[718px] min-w-full ...">
+```
+
+Fixed width of 718px causes horizontal scroll on devices < 718px. The `min-w-full` doesn't override the explicit width.
+
+#### User Impact
+- Horizontal scroll on tablets and phones
+- Content cuts off
+- Poor UX for 80% of mobile users
+
+#### Recommended Fix
+```tsx
+// ✅ Improved
+<div className="absolute left-1/2 top-full w-full max-w-[718px] min-w-full ...">
+```
+
+Or use container-based approach:
+```tsx
+<div className="absolute left-1/2 top-full w-[95vw] max-w-[718px] ...">
+```
+
+**WCAG Impact**: Affects 2.1.1 Keyboard (mobile users)
+**Severity**: 🔴 Critical
+
+---
+
+### 2. Non-Responsive Text Sizes
+
+**Files**: Multiple components
+**Lines**: Various
+**Breakpoint**: All
+
+#### Issue
+Hard-coded pixel values don't scale:
+
+```tsx
+// ❌ Problem examples
+text-[10px]  // Too small on large screens
+text-[80px]  // Too large on mobile
+text-[115px] // Causes overflow
+
+// Found in:
+- apps/web/src/components/Brand/ColorList/index.tsx
+- apps/web/src/components/GetStarted/Hero.tsx
+- apps/web/src/components/Layout/Navigation/Sidebar/Logo.tsx
+```
+
+#### User Impact
+- Text illegible on mobile (< 16px considered inaccessible)
+- Text overflow causing horizontal scroll
+- Inconsistent typography scale
+
+#### Recommended Fix
+Use Tailwind's responsive text utilities:
+
+```tsx
+// ✅ Mobile-first responsive text
+className="text-xs sm:text-sm md:text-base lg:text-lg"
+
+// ✅ Or use clamp for fluid typography
+font-size: clamp(0.875rem, 2vw + 0.5rem, 1.25rem);
+```
+
+**WCAG Impact**: 1.4.4 Resize Text (Level AA)
+**Severity**: 🔴 Critical
+
+---
+
+### 3. Tiny Touch Targets on Mobile
+
+**File**: Multiple button components
+**Breakpoint**: Mobile
+
+#### Issue
+Buttons and interactive elements < 44x44px on mobile:
+
+```tsx
+// ❌ From AgentKit/Hero.tsx (Line 48)
+<button className="...px-4 pb-3 pt-3...">
+
+// ❌ From TopNavigation (Line 69)
+<Link className="...px-6 py-2...">
+```
+
+On mobile, `py-2` = 8px padding = ~24px total height (below 44px minimum).
+
+#### User Impact
+- Difficult to tap accurately
+- Frustrating mobile experience
+- WCAG AA violation
+
+#### Recommended Fix
+```tsx
+// ✅ Ensure minimum 44x44px on mobile
+className="px-4 py-3 sm:py-2 min-h-[44px] sm:min-h-0"
+
+// ✅ Or use larger padding base
+className="px-6 py-3 sm:px-4 sm:py-2"
+```
+
+**WCAG Impact**: 2.5.8 Target Size (Minimum) - Level AA
+**Severity**: 🔴 Critical
+
+---
+
+## High Severity Issues
+
+### 4. Fixed Image Sizes
+
+**File**: `apps/web/src/components/Builders/AgentKit/Hero.tsx`
+**Line**: 30
+
+#### Issue
+```tsx
+// ❌ Current
+<Image
+  src={agentkit}
+  alt="agentkit"
+  width={32}
+  height={32}
+  className="w-5 h-5"  // Fixed size, doesn't scale
+/>
+```
+
+#### Recommended Fix
+```tsx
+// ✅ Responsive image sizing
+<Image
+  src={agentkit}
+  alt="AgentKit SDK icon"
+  width={32}
+  height={32}
+  className="w-4 h-4 sm:w-5 sm:h-5 md:w-6 md:h-6"
+/>
+```
+
+**Severity**: 🟡 High
+
+---
+
+### 5. Excessive Bottom Padding on Mobile
+
+**File**: `apps/web/src/components/Builders/AgentKit/Hero.tsx`
+**Line**: 47
+
+#### Issue
+```tsx
+// ❌ Current
+<div className="flex gap-4 pt-4 pb-24 bg-black max-sm:flex-col md:pt-5">
+```
+
+`pb-24` (96px) is excessive on mobile devices with limited vertical space.
+
+#### Recommended Fix
+```tsx
+// ✅ Responsive padding
+<div className="flex gap-4 pt-4 pb-8 sm:pb-12 md:pb-16 lg:pb-24 bg-black max-sm:flex-col md:pt-5">
+```
+
+**Severity**: 🟡 High
+
+---
+
+### 6. Fixed Min-Height Breaking Layout
+
+**File**: `apps/web/src/components/Brand/ColorList/index.tsx`
+
+#### Issue
+```tsx
+// ❌ Current
+className="... md:min-h-[130px] ..."
+```
+
+Fixed min-height can cause layout issues on varying content.
+
+#### Recommended Fix
+```tsx
+// ✅ Use aspect-ratio instead
+className="... md:aspect-video ..."
+
+// Or remove min-height and let content dictate
+className="... md:py-8 ..."
+```
+
+**Severity**: 🟡 High
+
+---
+
+### 7. Non-Fluid Container Widths
+
+**File**: Multiple layout components
+
+#### Issue
+Missing `container` class or max-width constraints cause content to stretch too wide on large screens.
+
+#### Recommended Fix
+```tsx
+// ✅ Add container with max-width
+<div className="container mx-auto max-w-7xl px-4 sm:px-6 lg:px-8">
+  {children}
+</div>
+```
+
+**Severity**: 🟡 High
+
+---
+
+### 8. Overflow Hidden Cutting Content
+
+**Files**: 54 components with `overflow-hidden`
+
+#### Issue
+While `overflow-hidden` is useful, it can hide content like dropdowns, tooltips, or focus indicators.
+
+#### Audit Required
+Review each usage of `overflow-hidden` to ensure:
+- Focus indicators aren't clipped
+- Dropdowns aren't cut off
+- Mobile menus work correctly
+
+**Severity**: 🟡 High
+
+---
+
+### 9. Fixed Gap Spacing
+
+**Issue**: Using fixed `gap` values that don't scale
+
+```tsx
+// ❌ Problem
+<div className="flex gap-6">
+
+// ✅ Better - responsive gaps
+<div className="flex gap-2 sm:gap-4 md:gap-6">
+```
+
+**Severity**: 🟡 High
+
+---
+
+## Medium Severity Issues
+
+### 10. Missing Responsive Modifiers
+
+**Issue**: Many components lack breakpoint-specific styles.
+
+#### Pattern to Follow
+```tsx
+// ✅ Mobile-first approach
+className="
+  flex-col      // Mobile: stack
+  sm:flex-row   // Tablet+: horizontal
+  gap-2         // Mobile: tight
+  sm:gap-4      // Tablet+: comfortable
+  p-4           // Mobile: padding
+  sm:p-6        // Tablet+: more padding
+  lg:p-8        // Desktop: generous
+"
+```
+
+**Severity**: 🟠 Medium
+
+---
+
+### 11. Absolute Positioning Without Responsive Adjustments
+
+**Example**: Submenu dropdown
+```tsx
+// ❌ Fixed positioning
+className="absolute left-1/2 top-full"
+
+// ✅ Should adapt on mobile
+className="absolute left-0 sm:left-1/2 top-full w-full sm:w-auto"
+```
+
+**Severity**: 🟠 Medium
+
+---
+
+### 12. Button Width Inconsistency
+
+**File**: `apps/web/src/components/Builders/AgentKit/Hero.tsx`
+**Line**: 50
+
+```tsx
+// ❌ max-sm:mr-auto causes alignment issues
+className="... max-sm:mr-auto"
+
+// ✅ Better: full width on mobile
+className="w-full sm:w-auto"
+```
+
+**Severity**: 🟠 Medium
+
+---
+
+### 13. Z-Index Stacking Issues
+
+**Pattern**: Multiple components use random z-index values
+
+```tsx
+// ❌ Inconsistent z-index
+className="z-10"
+className="z-50"
+className="z-[9999]"
+
+// ✅ Use Tailwind's scale consistently
+z-0, z-10, z-20, z-30, z-40, z-50
+```
+
+**Severity**: 🟠 Medium
+
+---
+
+## Low Severity Issues
+
+### 14. Missing Landscape Tablet Styles
+
+**Breakpoint Gap**: 768px - 1023px (landscape tablets)
+
+Many components jump from mobile to desktop styles, missing tablet-specific optimizations.
+
+**Recommendation**: Add `md:` breakpoint styles more consistently.
+
+**Severity**: 🟢 Low
+
+---
+
+### 15. Transition Duration Inconsistency
+
+**Issue**: Different transition timings across components
+
+```tsx
+// Found variations:
+duration-200
+duration-300
+transition-all
+```
+
+**Recommendation**: Standardize on design system values.
+
+**Severity**: 🟢 Low
+
+---

+### Testing
+
+```bash
+# Test metadata locally
+yarn dev
+# Open http://localhost:3000/your-page
+# Check <head> tags in browser DevTools
+
+# Validate structured data
+# Paste page HTML into: https://validator.schema.org/
+
+# Check Open Graph
+# Test at: https://www.opengraph.xyz/
+
+# Verify Twitter Card
+# Test at: https://cards-dev.twitter.com/validator
+```
+
+---
+
+## Common Mistakes to Avoid
+
+### ❌ Duplicate Titles/Descriptions
+
+Every page must have unique metadata. Don't reuse the same title/description.
+
+### ❌ Keyword Stuffing
+
+```
+// ❌ Bad
+"Base Ethereum L2 blockchain Base L2 Base blockchain Ethereum Base"
+
+// ✅ Good
+"Base: A secure Ethereum L2 blockchain for developers"
+```
+
+### ❌ Missing Alt Text
+
+All images must have descriptive alt text for accessibility and SEO.
+
+### ❌ Broken Links
+
+Check internal and external links regularly. Broken links hurt SEO.
+
+### ❌ Thin Content
+
+Pages with < 300 words rarely rank well. Provide comprehensive content.
+
+### ❌ Slow Loading
+
+Page speed is a ranking factor. Keep pages under 3 seconds load time.
+
+### ❌ No Mobile Optimization
+
+70%+ of searches are mobile. Always test on mobile devices.
+
+---
+
+## Getting Help
