Search Engine Optimization (SEO) - Webmaster Tools Help
Keep in mind that the Google search results page includes organic search results and often paid advertisement (denoted by the heading "Sponsored Links") as well. Advertising with Google won't have any effect on your site's presence in our search results. Google never accepts money to include or rank sites in our search results, and it costs nothing to appear in our organic search results. Free resources such as Webmaster Tools , the official Webmaster Central blog , and our discussion forum can provide you with a great deal of information about how to optimize your site for organic search. Before beginning your search for an SEO, it's a great idea to become an educated consumer and get familiar with how search engines work.
