Google Panda 2.5 has website owners wondering after seeing the effects of organic traffic declining on September 27, then recovering on October 3, only to decline again on October 13. The Google algorithm has changed due to incorporating new signals and updating the recalculation of site performance within the algorithms. It updated data about site performance after the last recalculation. These updates have happened several times within days or weeks of each other, and occurred in both the Panda algorithm and the recalculation updates.
These changes have affected even high-quality pages since September 27 because Panda uses a site-wide assessment. There are some recovery strategies to overcome any negative effects. These include making sure you create valuable content so that your page is the best answer when queried on the web. If many pages on your site are about the same topic, you should consolidate any duplication scrape google search results. Google wants to make the sure that you are creating a valuable and engaging experience for the user by providing easy navigation that is useful and does not obscure your content with too many ads. Google Panda 2.5 is designed to award site builders who provide engaging content and pages where people want to stay, link to, and return to, while sharing, and otherwise showing happiness.
Google Panda 2.5 is an effort to improve the Google experience for its users by improving search results via a new search algorithm. The focus is to lower the ranking of low quality sites and display the highest quality sites to users. The latest changes have helped the rankings of sites which provide news and social networking while lowering rankings for advertising sites. The original Google Panda rolled out in February of 2011 for the United States and then went global in April. Since then it has received several updates due to complaints from website owners that pages with scraping and copyright infringement were getting better rankings than those with original content. Google has since asked the public for input for how to better detect scrapers. Google has an advisory in its blog to give direction to website owners to evaluate the quality of their own website.
Google Panda 2.5 does not run continuously since it takes enormous computing resources to process the analysis. It runs periodically to calculate the values it needs to update results. So if a site is flagged, Panda will not see improvements until the next time scores are assessed, which has so far happened on a 4 to 7 week schedule. The update is meant to close algorithm vulnerabilities, reduce spam, and detect low quality content while reducing the rank of content farms and improving scraper detection.
Google’s algorithm uses artificial intelligence after using human quality testers to rate thousands of websites on measures of quality, design, and trustworthiness as well as the speed which the page loaded and whether or not the tester would return to the website. This information was then applied to make the algorithm more sophisticated and scalable. When Panda was introduced, it introduced many new factors to rank pages and downgraded the importance of factors like PageRank.
