This month was pretty packed with a ton of SEO tips but the big items included many penalties, mostly manual actions. We had product review penalties, rich snippet penalties, clickjacking penalties and more warnings after warnings. Did you know Google sent about 500 manual actions per hour last year?

Google also updated thequality raters guidelines and update the local rankings document. Google brought backin-depth articles after it going away and extended featured snippets.
