A Google search is an easy, fair and objective way to find high-quality web sites with information relevant to your search. Google's ranking technology or algorithm (known as PageRank) continues to provide the basis for all of Google's web search tools. There are several criteria that Google considers when ranking websites (page rank, link popularity, keyword density, age of domain, page title, page name, domain name, etc.).
Google's complex, automated methods make human tampering with results extremely difficult. Google does not sell placement within the results themselves (i.e., no one can buy a higher PageRank), according to Google. The ad results displayed on the left side of Google is considered FREE. This is what is referred to as organic results, free listings or natural listings.
