Google has changes happening all the time to the algorithms. Usually it’s nothing much to bat an eye at. It happens so often and people make such a fuss, get upset, then settle down and carry on with life.
Usually I just let the changes float right past me and don’t give them much of a thought as they usually have a much smaller impact than everyone believes.
However, this time it’s different. It is so important to know if your site will stay in search engine rankings with these new changes.
