SEO
Search Engine Optimization (SEO) is the process of improving the visibility of a website in search engines via the "natural" or un-paid search results. In general, higher ranked on the search results page(the the earlier it appears), and more frequently a site appears in the search results list, the more visitors it will receive from the search engine's users.
As an Internet marketing strategy, SEO considers how search engines work, what people search for and the actual search terms typed into search engines. Optimizing a website may involve editing its content and coding to both increase its relevance to specific keywords and to remove barriers to the indexing activities of search engines.
Promoting a site to increase the number of backlinks (or inbound links) is another SEO tactic, but this strategy should be used sparingly as there is a possibility that very sharp increases in would cause the search engine to assume you were just buying links and penalise for this.
