Google looking to improving search quality and reducing webspam

Blog post by Google's Principal Engineer, Matt Cutts, mentioned Google's constant effort in improving search quality and reducing webspam. Webspam is defined as junk you see in search results when websites try to cheat their way into higher positions in search results or otherwise violate search engine quality guidelines.

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. 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.
