As “pure webspam” has decreased over time, attention has shifted instead to “content farms,” which are sites with shallow or low-quality content. In 2010, we launched two major algorithmic changes focused on low-quality sites. Nonetheless, we hear the feedback from the web loud and clear: people are asking for even stronger action on content farms and sites that consist primarily of spammy or low-quality content.

'The aggregators fill their websites with news, opinion, features, photographs and video that they continuously collect – some would say steal – from other national and local news sites, along with mostly unpaid postings by bloggers who settle for exposure in lieu of money,' Downie said. 'Though they purport to be a new form of journalism, these aggregators are primarily parasites living off journalism produced by others. They attract audiences by aggregating journalism about special interests and opinions reflecting a predictable point of view on the left or right of the political spectrum, along with titillating gossip and sex. Revealing photos of and stories about entertainment and celebrities account for much of the highly touted web traffic to the Huffington Postsite, for example.'
