I always like to make sure that the SEO services I offer are up-to-date. And what better way to stay on to of it than to go straight to the source? Every so often Google updates their algorithm. Some of these updates change everything, while others are small and unnoticeable. But, I’m sure all of us to some degree have experienced fluctuations in search rankings due do the high amount of updates happening over the past couple years.
Here are links to 4 blog posts from Google’s Inside Search Blog announcing the different changes to their algorithm;
That’s 137 updates to Google’s Algorithm. I remember in 2006 when Google said they have 297 ranking factors. I can’t imagine how many they have now. Anyway, I’ve listed the most important updates that we as SEO specialist should make sure we understand. ( | = update to update a month or 2 later)
