With JetPack for WordPress, Automattic is releasing wordpress.com features for WordPress Self Hosted websites.
One of that release is one feature called ‘Related Posts’ where by you can activate this inbuilt plugin like functionality to scan your self hosted website & display desired number of related posts under each blog post.
This feature helps user to discover & read related post category content more easily & it also increases website’s click through rate i.e. Average pages visited by each website visitor.
But it sometimes doesn’t show any related posts under any blog post, but there is reason why it acts up that way.
Reason what I received from talking to Support staff at Automattic is something like this:
We don’t try to find related posts until there are 10 published posts to try to ensure there’s a fair amount in the index to produce good results.
If your other sites have more then 10 posts, can you reindex the site by visiting the Jetpack page, clicking Learn More on the Related Posts module and then click the Index button that appears?
Hope this helps,
Thanks & Regards
