To remove links from our site, we return a 410 code on on the links we want removed, and shows
The page you requested was removed..
In Webmaster Tools, I see all the 410 pages in Crawl Errors / Not Found.
I'm worried that because they appear in Crawl Errors that they could be negatively affecting SEO rankings. Is that the case, and if so, should I change the return codes from 410 to something else?
