User behaviour a critical factor for Google

As we all know that google is the main search engine in the world. The results which are showed by google provide good information as compared to other search engines. But how google provide a relative information. Yesterday I read an article on seo. It was suggested that google collect all the information from its user behaviours. User behaviours means that any number of actions taken by users while using google search engine. Google collect all the information about visitors action, its moving from one side to another and save this information to their documents. Basically google wants to know that what type of information user like and dislike.

Google may also noted that what users do when it visit a website which is index by it. Google collect all the information through its toolbar, google bookmarks, News alert and a simple cookie which feed data back to google servers. The main reason for increasing the popularity of google is that it provide information according to visitor requirements. Today, millions of website pay a large amount of money to seo company for ranking high in search engine results. But if the site owner make the site according to their visitor point of view than a particular website automatically rank high in SERPs. A website owners should make their site more informative.
