I have a question about the possibility to display three similar posts at the end of each blog post. My problem is that the similar postings that are being suggested mostly don’t have any connection to the post they are displayed under. Why is that and is there any way to improve the “match” between the similar posts and the main post?
“Recent Post” is a default WordPress plugin and there is no such facility to change in that.
But if you want to add extra criteria in the recent post then you can use other recent post plugins.
