As “pure webspam” has decreased over time, attention has shifted instead to “content farms,” which are sites with shallow or low-quality content,” says chief engineer at Google, Matt Cutts, on the group’s official blog.
“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. We take pride in Google search and strive to make each and every search perfect. The fact is that we’re not perfect, and combined with users’ skyrocketing expectations of Google, these imperfections get magnified in perception. However, we can and should do better,” he added.
This particular tool detects the best expressions and words common on such sites. Cutts also assured that Google is trying to identify the websites full of copied content.
However, Google has ensured that the current amount of “webspam” represents only half of what it was five years ago.
