Google has stuck with its story that the various components of Google+ and the +1 button don’t have an effect on search rankings. They have to. Once they admit that it does (as countless studies and tests have indicated), the flood of spam and blackhat SEO techniques will grow larger than it already has. This is important to understand for anyone doing research on the topic. Google isn’t trying to deceive people for the sake of being deceptive. They’re trying to protect the sanctity of what will become their greatest advantage in the ongoing search engine wars. They will not sit back and do what Yahoo did a decade ago, relying on mass adoption to carry them through. Just because Google is on top today doesn’t mean that they have no fears for the future.
