Google announced what may ultimately be one of the biggest changes to their algorithm yet.
From the Official Google Blog: “Many of the changes we make are so subtle that very few people notice them. But 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 are low-value add for users, copy content from other websites or sites that are just not very useful.”
After receiving a lot of criticism, over the past few months, regarding the quality of its search content Google has finally decided its time to look into this problem and fix it.
Earlier this week Google announced that they realized that the deteriorating quality of search content on its search result page were posing a serious threat to the reputation of the company and that they will be taking action against spammers.
Matt Cutts said in an interview that the spam content on the English result pages are less than half of what it was five years ago but they have noticed a small but significant rise of spam over the past few months. This certainly correlates with our readers’ feedback.
Here is Matt’s view of the issue:
Google has been thinking for quite some time about how to deal with content that isn’t obvious spam but is clearly not designed with the best interests of the user in mind. Google needs to be open to ways where we can improve.
Cutts also stated that his team was already on the job and that some changes will be made in the search algorithms to specifically tackle the recent increase in spam results that are showing up on the search result pages.
According to Matt, after the launch of their a new version of Google Caffeine, Google has been indexing a lot more content that include spam and to deal with the spam content they have recently launched a redesigned document-level classifier that makes it harder for on-page spam content to rank highly.
The new classifier is better at detecting spam on individual web pages, e.g., repeated spam words—the sort of phrases you tend to see in junky, automated, self-promoting blog comments.
Apparently, Google has also been developing its hacked site detecting ability and is testing some new changes, including one that penalizes websites for copying the content of others without having original content of its own. Sounds pretty good to me!
Google hasn’t forgotten about content farms either – they are firmly in their sights in 2011. Google has introduced two changes in its search algorithm that will block the low-quality sites from showing up with high rankings on the SERPs.
It would appear that Google isn’t going to let anything stand between it and search quality, even if that means taking down thousands of spammers and content farms in the process.
