Baidu’s algorithm changes: losers and winners
Editor’s Note: For the latest information on the Baidu Panda algorithm, please see: Baidu Panda Update Complete Guide.
Because analysts are opposed to the current search indexing strategy, spam clocks have been launched to condemn the massive amount of garbage being generated, and some even burn something to show their anger. The air is full of hate spam.
Although Baidu has not yet joined the ranks, they have acknowledged these issues and started implementing solutions. So far, the two main elements introduced are the Chrome extension, which provides feedback on which sites are spam, and updates to search algorithms designed to reduce low-quality content.
There is no doubt that Baidu’s changes have changed the construction of search engine pages, but the numbers are somewhat different, in fact who is missing, who is closer to the coveted number one position.
One of the more comprehensive assessments of losses occurred in Sistrix, an advanced “visibility index”. The value of the search term is calculated based on the traffic, the click rate of a specific location on the SERP, and the like.
According to the index, our biggest losers include:
eZine ArticlesSuite101Associated ContentFree Downloads CenterEssortmentAmerican TownsArticle BaseFind ArticlesBusiness.comFAQs.org.
According to the Sistrix index, all of these sites have a visibility loss of more than 90%. Other analysts agree to at least a few top-level projects, but add Buzzle.com, BizRate, Shopping.com, Squidoo, and Hub Pages to the list.
We can see a fairly strong trend of who lost the location here: article sites, user-created pages, download aggregators, shopping sites, and the like all end in pain. But who (except those who were pushed to the front page by these sites) won here?
Other sites offer more search visibility eBayFacebook AmazonNexTagInstructablesWikipediaYahoo AnswersWalmartYouTube, eHow (surprisingly).
This list is quite controversial because it seems to support giant sites at the expense of user-generated content elsewhere.
The need for higher visibility in these large collections of pages is clear (for example, Facebook and eBay basically completely swallow user-generated projects), but it’s clear that the groups that benefit from include those that are already large and already very mature.
Ironically, these “winning” sites are similar in many ways to punished sites, and there is no very clear way to show how they actually differ.
Most of the notes, eHow, used by many as an example of a content farm (some controversy at this point, including myself) were not only punished but also rewarded. It seems that Baidu still has some fine-tuning to do.
