History of Google Algorithm Changes

When folks tell me they had someone SEO their site as if it’s a single event, I always question the person doing the work. Optimization isn’t a project that starts and stops. Competition is always changing, technology is always changing, the audience is always changing… and the Google Algorithm is always changing. We’ve previously posted just on Google Panda changes – but this infographic is much more comprehensive. Keeping on top of these changes is a constant effort… and aggressively implementing recommendations from Google on the algorithm changes can keep you ahead of your competition and improve your overall results.

  1. I’ve got one for you, buddy:  What do you think the difference between Panda and the new over-optimization penalty will be? Right now, it feels like the department of redundancy department and everyone who’s referencing Matt Cutts’ latest video on Over-Optimization apparently didn’t watch the video because keyword stuffing and hidden text has been getting you in trouble since the introduction of Google Webmaster – Fall 2007 if I recall.

  2. Google has always been evolving and making changes, but clearly 2011 was a big year.  Google wants to provide its users with the best possible results.  As SEOs, it’s important for us to be aware of these algorithm changes and keep tabs on our sites.
