“Next week, we'll launch the “helpful content update” to tackle content that seems to have been primarily created for ranking well in search engines rather than to help or inform people. This ranking update will help make sure that unoriginal, low quality content doesn’t rank highly in Search, and our testing has found it will especially improve results related to online education, as well as arts and entertainment, shopping and tech-related content.”

The update, as Google says, is aimed at low quality sites that have been constructed purely to game the algorithm, by including specific keyword matches and data notes that align with key Google search trends.

I've been helped by just about every Google update since Panda. Still a bit of a squeeky bum time knowing your traffic and income could be wiped out shortly (for those of us who rely on Google traffic).
