Google Panda and Penguin have come a long way since their launches. The latest updates that were introduced in 2011 and 2012 respectively are in the limelight for several reasons.
Google Panda was introduced to lower the search engine rankings of “low quality” sites, which are sites that have infringed the copyrights of others and are not very useful, thus providing better rankings for sites with “better content”. Google Panda is named after Mr. Navneet Panda and has actual people testing sites on content, design, reliability etc. It is updated from time to time, although the Google forums have been filled with complaints from websites claiming to hold low rankings despite the original content. Panda affects the operational base of a website by affecting the site as a whole, not just individual pages.
The recovery after this algorithm is tough as the sites lose traffic for a considerable period of time before any amends by Google is made. Launched earlier this year, Penguin started a fight against the spam sites making web surfing not only easier but safer. The penalty called the "over optimization penalty" is targeted against the spamming sites.
There are ways in which the "Google Panda/Penguin" effect can be put at bay. To recover sites from Panda, one needs to start writing and publishing quality content as with new algorithms. The bar for standard sites has been raised. With penalized websites because of violations, it is best to remove poor quality material and unnecessary advertisements. Learning the basics of SEO and not promoting plagiarism works well. Also, one needs to become more social as Google can get to know the traffic of a site by the percentage of clicks, assuring good quality of sites. As they say, an excess of anything is bad- same goes for keywords and links. This could be seen as a popular strategy to win traffic for the website, but the latest Google updates stand strongly against it.
For Penguin recovery, one needs to have an adequate knowledge of Google webmaster tools for an efficient SEO. One needs to make the website contents user friendly by reducing the number of links and advertisements just like Google Panda. The high bouncing rates are usually caused by unfriendly content. Verbose content on spamming sites calling out for attention on Google for prospective clients isn't very alluring and must be removed if Google Penguin is not desired. Three basic actions should be taken for prevention of an attack. One should be to minimize the poor quality content, the second is to scrap contents of any violations of Google, and the third and the foremost, a back link profile needs to be created with the help of SEO and OSE tools.
The problems experienced with both these mechanisms deeply reflect the era of cut-throat competition. Somebody's loss is another person’s gain. Although there is no specific way to assure recovery, it helps in protecting sites in future.
