Google’s relationship with links has changed over the last 15 years – it started out as a love affair but nowadays the Facebook status would probably read: “It’s Complicated”. I think Google are beginning to suffer from trust issues, brought about by well over a decade of the SEO community manipulating the link graph. In this post I’m going to lay out how I think Authorship, and Google+ are one of the ways that Google are trying to remedy this situation.I’ll move on to what that means we should be thinking about doing differently in the future, and am sharing a free link-building tool you can all try out to experiment with these ideas. The tool will allow you to see who is linking to you rather than where is linking to you, and will provide you with social profiles for these authors, as well as details of where else they write.
