A lot of webmaster got “unnatural link profile” warnings in their Webmaster Tools in the past few months and a lot of webmasters were left not knowing which links they should take down and which links they should leave alone.
Google is starting to come out with ways webmasters can know what type of links are bad. They will not give us a comprehensive list, but they will give us a good idea. If Google were to come out and say exactly which links are good and which are bad it would give SEO’s more insight into how to game the search engines. Google is limiting the knowledge they give us while trying to help at the same time, which causes of vagueness in the messaging from Google.
