This week Google announced major algorithm update that is shaking up entire business models. The update, called “Panda,” is a response to many Google users to what has been seen as an unfair advantage given to content farm sites, many of which publish thousands of subject-specific articles per week. The widely held perception that such models produced low-quality content that prevented even high school students from conducting effective online research is thought to be the impetus for the change.
The algorithm changed has caused some sites to lose as much as 90% of their referral traffic from Google, triggering layoffs from Suite101.com and others. Sites such as Yahoo’s Associated Content, WiseGeek.com and eZine articles were among some of the sites hardest hit by the update.
While this seems like an affirmation of Google’s longstanding message – create quality content for your audience – it’s not yet clear how Google is measuring content quality within its algorithm.
