Google Panda 4.2 update

Google Panda 4.2 update

his first victims



The update of Google's algorithm, deployed in France last week, degrades the visibility of non-value-added sites, such as price comparators or content aggregators.

Google has decided to clean up its search results with the update "Panda" of its algorithm. Available since February for requests in English, Panda was deployed at the end of last week in many other languages, including French. His mission ? To make fall in its classification sites which Google considers to be of low quality, but which trust the first results of the requests. In other words, aggregators and other "content farms".

Who has already done a search on Google for information on a model of computer or television has made the bitter experience: pages and pages of price comparisons more or less obscure, before finally finding the information sought. These aggregators operate on a simple principle: take back some of the content of other sites, and redirect the user.

The aggregator, thanks to a clever SEO optimization game (SEO, search engine optimization), is at the top of the Google results. The user will be more likely to click on it, which translates into juicy advertising revenue for the site in question. But user side, the passage on such site is only of limited interest. In addition, to see appearing at the head of the results a listing of prices compared to the leading online merchants while seeking advice on the quality of a television model can be experienced as a pollution of his research.


Drop in visibility of consumer opinion sites

Unsurprisingly, the arrival of Panda in France has resulted in a drop in visibility of these aggregators and price comparators, but also sites that list promotional codes, or online directories. Search Metrics has released the losers list for this update. Dico net loses 88% of visibility, How is it 81%, Wikio 74%, Easy to buy 53%, 123 people 49%, Twenga 47%, Net Info 44%, Buzz Driver 41% ... More Surprisingly, consumer opinion sites, which could be judged much more qualitative than price comparators, are also affected by Panda (-62% for Ciao, -85% for Yelp, -20% for Qype) . The visibility of certain news sites, such as Le Parisien.fr (-10%) and L'Express.fr (-17%), is also degraded.


If some sites fall in the Google results, others benefit from this new distribution of cards, because Panda wants to "boost" the referencing sites said quality. Video sharing sites are ranked higher (+ 52% for YouTube, 43% for Dailymotion, 18% for Wat), as well as social networks (+ 25% for Twitter, + 10% for Facebook). Wikipedia earns 8% of visibility, service-public.fr 17%.


While these figures are impressive, the impact of Panda remains minimal in terms of queries made daily by users. Google noted on his blog that the launch of Panda in English, 12% of the results were affected by the new algorithm.
