When you visit Google’s “About Our Company” page, the first thing you see is the quote, “Organize the world’s information and make it universally accessible and useful.” That’s Google’s mission statement, and it means that Google is working to provide the best and most relevant search results it can to its users.
However, it’s essentially up to a webmaster to prove to Google that his or her own site’s content is relevant to search queries and belongs near the top of search results. Google uses more than 200 factors to determine a website or webpage’s ranking in their search results, each factor with its own level of importance.
