Matt Cutts has released a video where he says that “Backlink Relevancy Is A Big Win In Terms Of Search Quality”. So make sure you get links from relevant sites only.
Question: Hi Matt, does the big G have a version of the search engine that totally excludes any backlink relevance? I’m wondering what search would look like and am curious to try it out
Answer by Matt: It turns out backlinks, even though there’s some noise and certainly a lot of spam, for the most part are still a really, really big win in terms of quality for search results.
