HTTP 404 Not Found-Server can't find requested resource. Links are considered broken or dead
Credit: Google / Social Media
Soft 404 – The server sends 200 OK for the requested page, but Google thinks it should return 404
Page with redirect - Forwards users and search engines from one URL to another
Alternate page with proper canonical tag – Google will just leave out the duplicate version and only index the main one
Duplicate without user-selected canonical – Identical or very similar content on your website
Crawled – currently not indexed – A specific page was visited and crawled by Googlebot, yet it was not indexed
Duplicate, Google chose different canonical than user – Google decides these URLs or pages to be duplicate and ignore
