Search engines are constantly seeking to provide the best information possible to their users. The more relevant their rank is, the more return users they have. This is why they reward websites that play by the rules, and offer the goods.
What are the goods? Content. Keywords. Keyphrases. The more you have, the more likely you are to get noticed by the spiders, who will reward you with a high rank for your industry.
There is no better traffic than free traffic - and that's what a rank provides. Filling your site with well-written, thoughtful, relevant content will assure you a boost in rank in the organic listings and a boost in free traffic.
