How We Picked The Best Related Post WordPress Plugins

The first thing we did was check installs and sales in combination with user ratings.

Also, we wanted to include only plugins that come with regular updates so you know it’ll run smoothly for years to come.

Another key factor that we always check is how great the support is. Because we don’t like to work with (“great”) plugins with poor customer service.

We then tested how responsive they are and how smoothly the featured posts area adapts to smaller screens.

It was also important for us to pick the plugins that have great customizations so that you can tailor their functionality to your website or blog specifically.

However, free plugins are more limited than premium ones but have the option to expand them and upgrade to pro.

One of the features that we really like is the ability to add featured posts via widget or shortcode manually, so they don’t appear on every single post if you don’t want to.

You must work on your website’s page experience because it’s also one of Google’s ranking factors.

And that’s when related posts come into play.

This simple technique is a great way to boost your user engagement and keep them on your site longer (hey, low bounce rate!).

Consequently, people will find related content faster; otherwise, they’d need to use your search bar and look for it manually. This may discourage the user to the point of leaving your website entirely.

And because related posts mean internal linking, you also automatically contribute to better on-page SEO.

Do we recommend using related posts?

We highly suggest you use the related posts functionality if you run a blog with many articles.

What’s cool is that some WordPress themes even come with this feature integrated, so you don’t even need to install a WordPress plugin.
