Check your posts (notes, articles, etc.) are marked up with h-entry:
Success!
We found the following like h-entry on your site:
Author
Like Of
The value for alike-of property should be a URL or an embedded h-cite.
Content
Published
URL https://mrkapowski.com/2019/01/6532
Syndicated Copies
Add URLs of POSSEd copies!
<a rel="syndication" class="u-syndication" href="…">…</a>
Categories
Add some categories! <a class="p-category" href="…">…</a>
Your h-entries should have, at minimum, the following properties:
e-content— the main content of the postp-name— if your post is an article with a name, use this classname.dt-published— the datetime the post was published at, in ISO8601 format, with a timezoneu-url— the canonical URL of the post, especially important on pages listing multiple posts
It’s a common convention for the published datetime to be a link to the post itself, but they can be separate if you want.
There should also be some way to discover the author of the post — either link to your homepage (which should have your h-card on it) from anywhere within the body of the page with rel=author, or optionally embed a p-author h-card in the h-entry.
The web is an expressive medium, and as such there are many other properties which you can add to your posts. Check out the h-entry documentation for a full list.
