SEO is symbol of search engine optimization which is the key to success in the business. No website has meaning if it is not properly promoted. Whenever any internet surfer is in search of any specific product, services or information he uses the simplest way of searching through search engine and this is habit of many people to only look in to five or six top websites for their purpose. No one has time to look in to 100 pages of search engine as there is no need when he finds in top pages.
