Google crawled our site a month ago and found 18,000 404 pages. But we got rid of those pages a few years ago. Is something wrong?
JOHN MEULLER (Webmaster Analyst from Google):
Yeah. So I think maybe a month ago or something like that, we had something where Googlebot went off and crawled a bunch of really old pages that we should know don’t exist. And that caused a lot of 404 errors. But these 404 errors don’t cause any problems on your side, in the sense that from a Search ranking point of view, we don’t care about this. If it’s a 404, that’s a perfect result code for us. We can ignore that page in the future a little bit and not crawl it as frequently. So that’s not something you’d need to take action on and fix those 404 errors if you know that these are really pages that should essentially have been gone.
