Google Panda – a change to the Google’s search results ranking algorithm – was first released in February 2011. Google released Panda to keep the right balance on the web, i.e. to lower the rank of low-quality websites and improve the rankings of high-quality ones. Soon it was noticed that Panda dropped the rankings of the websites with large amount of advertising. So while some of you may think that advertising brings money and does no harm, it has negative effects as well. Pure commercial websites are usually low-ranked; accordingly when building and maintaining a website, some website quality guidelines should be taken into account.
After some time, many people started complain that website with original content is ranked lower than the one with copied one. Google detected scrapers and updated Panda to measure quality of the websites in a more sophisticated and precise way than previously possible. It was successful and the Panda update was globally released in April 2011.
The next update is expected in January 2012.
What to consider before and after Google Panda update?
Keyword density: If the content is not unique and simply contains a bunch of words, instead of quality and appropriate ones, the website page rank will drop down. According to Google, the keyword ratio should be between 5-8 %; otherwise the search engine may skip the website until the next update.
Keyword relevancy: Keyword relevancy is also important to search engine. Google Panda will pay even stricter attention to keyword relevancy of the websites after January update. Some of the high-ranked and reputable websites like Forbes and PW Newswire have been affected for ranking for the keywords that are often abused. Thus, pay attention to keyword relevancy, determine whether you want to get traffic for the particular keywords and consider the type of the websites that rank for these keywords. This way you’ll discover the keyword authority.
Broken links issues. If the website contains broken links, you need to get rid of them or fix. There are a lot of broken link checkers that will save your time and show up the list of no longer active URLs on your website. Just type your website URL and the program will check it. Once you’ve found such a problem, immediately solve the broken link issues.
