On Twitter, Google posted the news earlier today, stating that this update will affect about one percent of search results.
According to SearchEngineLand, this has to be Panda update 3.9. Google last updated Panda a month ago, on June 25th.
Google Panda initially came out in February 2011 in an effort to weed out shady “content farm” websites from the search results. When it came out initially it was a shocker as 12% of websites were affected!
From Google’s own Webmaster Central website, to comply with Panda’s algorithm, one should ask the following about their own website:
- Would you trust the information presented in this article?
- Is this article written by an expert or enthusiast who knows the topic well, or is it more shallow in nature?
- Does the site have duplicate, overlapping, or redundant articles on the same or similar topics with slightly different keyword variations?
- Would you be comfortable giving your credit card information to this site?
- Does this article have spelling, stylistic, or factual errors?

- Does the article describe both sides of a story?
