I have tried Contextual Related Posts. It works well except that there are still GP links to the same related posts just below CRP.
The same happened when I tried Jetpack. With Jetpack, there is another thing: the option for putting a customised headline to replace the “Related” headline and it does show up in the preview but will not appear on the site in real view.
I prefer Jetpack.
Is there a way to use Jetpack, showing the related posts without GP links to the same posts?
