#Google recently shared their 2015 webspam repot. In it they said they served up 4.3 million manual actions in 2015 , that comes out to about 500 manual actions or Google manual penalties an hour!
Why so many manual actions? Well, in 2015, Google saw a 180% increase in hacked sites in their index, so they used both manual actions and the hacked sites algorithm to reduce them from showing up in the index. According to Google it is still a serious issue in 2016 so they have more work to do.
Google also said they “saw an increase in the number of sites with thin, low quality content. Such content contains little or no added value and is often scraped from other sites.” Google said they “sent more than 4.3 million messages to webmasters to notify them of manual actions,” and “saw a 33% increase in the number of sites that went through spam clean-up efforts towards a successful reconsideration process.”
Google received more than 400,000 spam reports and acted on 65% of them, and considered 80% of those acted upon to be spam.
