What's or Explain Google Panda Algorithm?

Google has so many algorithm filters even more than 500 to rank a website in their search results. Google has added one more filter called Google Panda to its algorithm filter for improving their search quality. Google panda, a filter that prevents low quality sites or pages from ranking well in their search result pages. In short, the main purpose of Google panda update is to lower the ranking(s) of "Low quality sites" or "the sites having thin content" while higher the ranking(s) of "High quality sites" or "the sites having high quality content". Panda is basically a 'filter' which identifies what does Google believes to be a "low quality page", and if a site has too much low quality pages then Panda indicates the site is a low quality site to Google. You can read more about Google Panda algorithm on Wikipedia page. The ideology is simple, avoid black hat SEO from your site, if any, and create quality content with proper on Page SEO optimization.

Google panda update was first released in February 2011. Google has now decided to fight with the web spam, and penalize the low quality sites in each panda update while rewards the high quality sites. I don't know what people think about Google, but without Google internet is nothing for me. Google has added few more algorithm updates into their search ranking factors including penguin and hummingbird so that people finding more high quality sites in Google search results. Google search now touches the sky due to their searchers, and Google knows it very well so Google always try to do their best for the searcher that is why few words have been well known to the world including Google Panda & Penguin.

The question, which site Google considers to be a high quality site? It is very hard to say the exact algorithm requirements. If Google reveals them few peoples may play game with search results. However, in mid 2011, Google has published an article, guidance on high quality sites on their webmaster blog, by which you can make a structure for a site to be a high quality site.

Google recommend you don't want to think so much about the algorithm such as panda update or penguin update, you just need to focus on delivering the best possible user experience and quality content on your site. You should always focus to provide information to your audience first. Few peoples are making mistakes when seo comes into the picture, they are more likely to write for the search engines first which cannot be a good thing for the site and the audience. You should ask the following questions to yourself for a site consider to be a high quality site.

  • Would you trust the information presented in this article?
