Related Posts by Taxonomy

By keesiemijer

Description

Quickly increase your readers’ engagement by adding related posts in the sidebar or after post content with a widget or shortcode.

Posts with the most terms in common will display at the top!

Reviews

Works good, light, secure

Many thanks for the plugin, I use it on many sites. Really good work. PS I need to open related links in a new window, submitted my topic in support forums

Very nice work

I really love this plugin. I was thinking if you guys could please include time options such that I can choose to show my latest posts and exclude old posts. Thank you.

Fantastically coded and well supported

On my bespoke site, I wanted to sort out 'related' posts for a specific post type. I was dreading the mess of comparing taxonomies and even considering which ones I should 'weigh' more than others. Plus I wanted to factor in some other fun mathematical aspects based on previously calculated values. I'd (cleverly, I thought) done the up front work of multiple custom taxonomies, where related posts could be found. And yes, I had the use of a faceted filtering engine to help people find things. But I wanted more. I wanted to be able to say "Did you like this show? Here are some more!" My goal was to get the code done pre WCUS, and I had just started to break out the work into manageable chunks over US thanksgiving, with the code beginning to take shape, when I thought "Surely someone has done this..." At first, all I found were plugins that did one job or another. One related your defined meta values, one let you manually chose, and so on. Then I found this one and struck the motherlode. Gold, I tell you, pure gold! Sure while it looked like just 'another' related taxonomy plugin. Then I read the documentation and was rhapsodic! @keesiemeijer put in the work to make it filterable and hookable! I could take that expert work and add on to it, using the basic related posts by taxonomies and add in my weird meta values. When I stumbled, I asked for help and found it with a brand new filter made just for insane people like me. Out of the box, this plugin works amazingly well. Fast, lightweight, and efficient. Add in those filters? It's the best thing since Betty White.
