Webmentions
This is beta. Likes from other sites can show on the Community tab, and count as kudos for that path.
Add this to your <head>. The same tag is in Kudos setup and on Community.
<link rel="webmention" href="https://tinylytics.app/webmention/YOUR_EMBED_CODE">
When someone likes your post on their own site, or through Bridgy, we check that the source page actually links to yours. Likes become kudos. Mentions and reposts show in Community.
In kudos stats you can filter source External to see which sites sent them.
