 When providing our content to AI, we can see a real-world ~7x saving in input tokens cost.

+## Curating content
+
+Other than the work making our content [discoverable](#ai-discoverability), most of the other work of making content for AI aligns with SEO or content best practices, such as:
+
+- Using semantic HTML
+- Adding headings
+- Reducing inconsistencies in naming or outdated information

+The only _special_ work we have done is adding a [`noindex` directives](https://developers.google.com/search/docs/crawling-indexing/block-indexing) to specific types of content (via a [frontmatter tag](/style-guide/frontmatter/custom-properties/#noindex)).
