Adding a Related Posts carousel in Divi can significantly boost engagement and capture visitors' attention, encouraging them to explore your site's content more.
A carousel of related posts can be added easily using a third-party Divi plugin.
Purchase the Divi Carousel Maker from the Marketplace
Install and activate the plugin on your website
Go to the WordPress Dashboard → Divi → Theme Builder
Click on the Add New Template icon
Chose the All Posts option
Click on the Create Template button
Click on the Add Custom Body option and edit it
Click on the Add Row icon
Click on the Add Module icon
Chose and add the Blog module
Go to the Content tab → Content → Post Count and set 1
Select the Current Category option
Clone the Blog Module three times (if you want to display 3 Related posts) by clicking on the Clone icon
Open the settings of each cloned Blog Module and increase the Post Offset value by 1
The first Blog module should have the Post Offset value set to 0
The second Blog Module should have the Post Offset value set to 1
The third Blog Module should have the Post Offset value set to 2
Edit the Row settings (that contains those 3 Blog modules) by clicking on the Gear icon
Click on the Gear icon for the Column
Go to the Carousel tab
Enable the Make This Column Carousel option
Save your settings
