May was an incredibly busy month for Google SEO related topics, specifically seeing Panda 4.0 roll out, the Google Spam algo being updated, press release sites taking a dive and several unconfirmed updates that Google wouldn’t talk about.

We also saw eBay get slapped, a popular site named MetaFilter talk about their Google penalty and a Nest competitor call out Google.

So it was a busy month!
