Which modules should I deindex?

The modules installed by default in Prestashop do not cause any problems, as they do not generate pages.

However, if you have modules that generate pages, you should ask yourself whether these pages are of good quality and if they are useful for Google.

If not, then deindexing the module is a good idea.

This is the case in particular for "wishlist" modules, which sometimes generate pages useful for customers but without interest for Google.

If you are unsure what to do with a module, I advise you not to deindex it.

It is preferable to have a few low-quality pages on your site rather than deindexing a page that brings you traffic.
