I keep seeing errors from other search engines and from Google now.
For example: small search engine has a SERPs page for example.com/folder/web-page.html
It links to the title of the page and has a meta description. Beneath the description, the url is displayed in plain text (no link). And usually the url is broken such as example.com/folder/web. It stripts out the -page.html and results in G spitting it out as a 404 error. I have hundreds of these from around 4 different small search engines.
Then I also have weird 404 errors which seem to be from G crawling its own SERPs with XML errors. Getting 404 errors for example.com/folder/web-page.html<web: and a bunch of junk after that which also includes whatever url is listed beneath me in the SERPs.
I've just been ignoring those errors, no idea if that is the right thing to do or not.
