Seo Course ~ Panda vs. Penguin - The Differences

Generally speaking, Panda and Penguin are the most knowing algorithms, which are use by Google to check the content of websites and to sort them in the search results in your browser. Just never know how the algorithms work and what changes they bring with updates, so SEO specialists can rely only on their own assumptions and observations. Small updates of algorithms come approximately every month and usually cause a little changes in the positions of the sites. Major updates of algorithms come an average of two or three times in a year (Google almost never informs you officially about dates of updates and about modifications of an earlier versions of the algorithms), and of course the result is a increase or decrease (often very large) of position of many sites.
