Google’s Amit Singhal announced of rolling out “search ranking” improvements in the U.S. only; and plan to roll it out elsewhere over time.
“In the last day or so we launched a pretty big algorithmic improvement to our ranking–a change that noticeably impacts 11.8% of our queries–and we wanted to let people know what’s going on. This update is “designed to reduce rankings for low-quality sites–sites which’re low-value add for users, copy content from other websites or sites just not very useful.” At the same time, it’ll “provide better rankings for high-quality sites–sites with original content and information such as research, in-depth reports, thoughtful analysis and so on.” explains Singhal.
“We can’t make a major improvement without affecting rankings for many sites. It has to be that some sites will go up and some will go down. 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.”
It’s worth noting that this update doesn’t rely on the feedback received from the Personal Blocklist Chrome extension, which was launched last week. However, “we did compare the Blocklist data we gathered with the sites identified by our algorithm, and we were very pleased that the preferences our users expressed by using the extension are well represented. If you take the top several dozen or so most-blocked domains from the Chrome extension, then this algorithmic change addresses 84% of them, which’s strong independent confirmation of the user benefits,” Singhal said.
