Dates of Major Google Algorithm Changes
The online community Reddit is a good way to while away time watching cat videos, more importantly the community offers a platform where SEO’s can chat and solve each other’s website issues. I’ve used a subreddit post and added extra information about the way Google has evolved over the years.

The Google Fred Update which we first spotted rolling out early morning on March 8th, 2017 seems to be fairly big. After reviewing well over 70 sites that were hit by this update, 95% of them share two things in common. The sites all seem content driven, either blog formats or other content like sites and they all are pretty heavy on their ad placement. In fact, if I dare say, it looks like many (not all but many) of them were created with the sole purpose of generating AdSense or other ad income without necessarily benefiting the user.
