SEO stands for search engine optimization and is the process of optimizing,
or maximizing your webpages, and the linking structure of other webpages,
which link to your webpage in such a way that the search engines give you higher rankings for your chosen keywords.
Whenever you enter a query in a search engine and hit ‘enter’ you get a list of web results that contain that query term. Users normally tend to visit websites that are at the top of this list as they perceive those to be more relevant to the query. If you have ever wondered why some of these websites rank better than the others then you must know that it is because of a powerful web marketing technique called Search Engine Optimization (SEO)
SEO is a technique which helps search engines find and rank your site higher than the millions of other sites in response to a search query. SEO thus helps you get traffic from search engines.
