What is SEO?

Search Engine Optimization or simply SEO is a powerful technique used to rank a website in search engines like Google, Yahoo or Bing for a particular keyword or search. Whenever we enter a keyword (say shoes) inside the search box of a search engine (say Google), a list of sites relevant to the keyword are shown. We tend to visit top sites because we believe that the top searches will be enough to satisfy our requirement. However, it seems really surprising that why some websites are shown at the top positions in search engine than the sites we must know. The answer to this question is SEO. Since, the site for that keyword is highly optimized that's why it is at the top position among the various other sites relevant to the same keyword. The more the site is optimized, the better it will be going to rank in search engine.

The mostly used Search Engines like Google, Yahoo! or Bing use crawlers or spiders to visit a site. These crawlers follow the internal links and many other links to index all the pages on the way. These indexed pages are kept in a giant database of search engine. Whenever a keyword is typed into the search box of a search engine, the most relevant indexed pages are shown as a result. How much a page is optimized for that keyword depends upon a number of SEO factors. Different sorts of SEO techniques for example, organisation of content to increase it's relevancy for the keyword, keyword density, internal or external links and many more, are used to optimize the page and hence it's ranking also improves. Search Engines use various algorithms to check the relevancy of a page.
