Google has adjusted the way its algorithm handles search rankings for low and high quality sites. The search giant makes unannounced tweaks to its engine all the time, but they're usually unnoticed by the masses. However, the latest update reportedly affects some 11.2% of the search giant's queries so the company felt it was appropriate to clue everyone in on the change.
The company has introduced an update that reduces rankings for low-quality sites and boosts rankings for high-quality sites. Google defines low-quality sites as those that copy content from other sites or sites that are "just not very useful." Conversely, the company recognizes high-quality sites as those that produce original content and information that includes research, thoughtful analysis and so on.
"Google depends on the high-quality content created by wonderful websites around the world, and we do have a responsibility to encourage a healthy web ecosystem. Therefore, it is important for high-quality sites to be rewarded, and that's exactly what this change does." Google hasn't specifically named what "low-quality" sites are affected, but an employee said that "people will get the idea of the types of sites we're talking about."
