Where do 404 pages come from in Google Search Console?

Question

Google

404 pages with addresses like /tag name/page/11 constantly appear in the Google console
. There is nothing on them in the "linking" pages. I mark it as corrected, but still climb dozens more. There are especially many of these in the "desktop" version. Where do they come from and what can be done?

Answer 1

First you need to understand what kind of pages and what the site works on. Most often it turns out that they are in a sitemap file forgotten by someone or there was a page with this type of page earlier and links were collected from it, they just get into the index late
