Support further social card formats

[ben519]

Sharing my content on platforms like Reddit, Twitter, and LinkedIn is really important to my site's traffic. And one thing I've learned from YouTube is that you need to have an enticing thumbnail for people to actually click on your post. It's a big deal - not a small one.

That said, here's what my content looks like shared on various platforms.

In my opinion, it's a bit lackluster. How can I make these images better, so more people click? What are you all doing for this?

Thanks for sharing your experiences! As you have noticed, social cards are currently produced in a single format – I'd be curious to learn what other formats from your and other users perspectives would be good to support, as I'm planning to extend the social cards plugin to allow for completely flexible layouts. This would also allow for producing arbitrary formats.

The main thing I'd like to see improved is the preview layout on Reddit which gets cutoff (I get a lot of traffic from Reddit). Other than that, just the ability to customize my images (e.g. replacing the default image my own PNG file). To be honest, I'm no expert on this topic so I'm not sure what formats should be supported.

Appreciate your help and quick reply as always!

Got it. I currently can't put an estimate on it, but when I find some time, I'll research other formats and see how to improve rendering for them as part of an improved social cards plugin. Can't put an estimate on it right now, but should happen this year!

In the meantime, if somebody else wants to share some research or experiences, that'll be awesome!

Summary
In summary, I would say if we have a padding option inside "Basic social cards" this would already help.
If then later on "Custom cards" would support to optimize the image per platform, this would be perfect.

1200 x 630 is a best practice format that works for a lot of platforms, but not for all of them, yes. We'll explore adding more templates with alternate formats in the future. You can already create your own with custom social cards ☺️
