Do you think it makes sense to make a sitemap FAQ because Google won't see the FAQ at all if we don't tell it it exists?

If you have internal links to FAQ page(s), google will discover it.

Yes, Google only sees the FAQ, but it doesn't go deeper to see everything that is written in the FAQ Items.

It should behave similarly to a blog because if we add a new page it has to be indexed which is not the case here.

If you think so, your idea about search engines is wrong.
Google will go much deeper.
Blog plugin has articles on separate URLs, FAQ plugin does not have link for every FAQ entry.

Yes you're right. Tnx

Sitempa pro plugin generate sitemap but some error.

if we create category and give name - still faq shows faq/new-category-c1  in sitemap url list.    here want to show category name

like - faq/abc-c1


this is bug - need to fix.  MB team pls guide in this isssue.
