What is SEO ? Why we need SEO ?
Search Engine Optimization (SEO) is often considered the more technical part of Web marketing. This is true because SEO does help in the promotion of sites and it requires some technical knowledge, at least familiarity with basic HTML.
SEO is sometimes also called SEO copyrighting because most of the techniques that are used to promote sites in search engines deal with text. Generally, SEO can be defined as the activity of optimizing Web pages or whole sites in order to make them more search engine-friendly, thus getting higher positions in search results.
One of the basic truths in SEO is that even if you do all the things that are necessary to do, this does not automatically guarantee you top ratings but if you neglect basic rules, this certainly will not go unnoticed.
Although SEO helps to increase the traffic to one's site, SEO is not advertising. Of course, you can be included in paid search results for given keywords but basically the idea behind the SEO techniques is to get top placement because your site is relevant to a particular search term, not because you pay.
