I am working on a site to do with domestic cleaning. When I check on Google Search Console, the page indexing section advises that there are thousands of pages that are either crawled but not indexed or discovered but not indexed. When I try to look at them, all return 404 error.
Google console advises the source is Google System not website.
Have been onto my hosting (hosting24.com) who simply say the pages do not exist. All my other pages that should be indexed are. Is this something I should be worried about? Would it effect my ranking?
