"Matt Cutts of Google posted an interested video on YouTube that shared the types of Google Webmaster Tools notifications they send out.Google sends out hundreds of thousands of notifications each month and 90% of those are black hat related, which we knew already.  But how about the rest?Black hat notifications is ~90%\r\nLow or no quality content is ~4%\r\nHacking is ~3%\r\nBuying links is ~2%\r\nSelling links is ~1%Here is the video:It is funny because I call out a Googler for the 4% on Google+ and then he calls me out for the 2% for dropping the link to the source.  Good times.Forum discussion at Google+.Image credit to Zazzle"^^<http://www.w3.org/2001/XMLSchema#string>
