Why is the search engine indexing a non-existent page of the site?

Question

Search Engine Optimization

I write site:http://my-domain.ru in the Yandex search line and see links to files that I deleted from the site a long time ago. For example, a week ago I had several html pages on the site, but I deleted them, and now I don’t have html permission files in any directory of the site, but the search engine shows them (Yandex even adds text to the snippet that was previously contained on the already deleted page) And I also see in the search results the currently existing pages in which I wrote the title and desription, but for some reason Yandex itself chooses the title and desription. I don't understand why, tell

me what to do

Answer 1

Maybe the robot just did not have time to go through your pages? Yandex somehow knows that they have not been deleted, it doesn’t monitor your site non-stop, but once in a while (maybe even once a week or even less often). Go to Yandex.Webmaster in the section Indexing -> Recrawl pages and specify the deleted pages there. The Yandex robot will try to crawl the deleted pages in priority order and mark them with a 404 error, after which it will remove them from the search results.
