Many webmasters and marketers think that a website will get a ranking boost on Google if it has links from .edu or .gov domains. Google’s Matt Cutts and Google’s John Mueller recently said that this wasn’t so:

“This is a common misconception – you don’t get any PageRank boost from having an .edu link or .gov link automatically. If you get an .edu link and no one is linking to that .edu page, you’re not going to get any PageRank at all because that .edu page doesn’t have any PageRank. [...] We generally treat all links the same – be it from .gov or .edu or .info sites.”
