Hello, What is your opinion: does Googlebot actually make mistakes, omissions? Because after years and years, I still see some pages of sites managed by me - unindexed, not showing up in Google Search as backlink to the rest of the site... seems like Google "forgot" or "left out" some of the pages. I was wondering if that was an omission. Quality pages, no over-SEO... just that I didn't use Google Sitemap. I think it is possible that Googlebot omits, forgets, jumps above the pages of smaller, less strong sites...
