Search engines are an extremely powerful way of promoting your website online. Consider them your silent Public Relations firm, 
quietly working in the background. Many studies have shown that between 40% and 80% of users found what they were looking for by using the search engine feature of the Internet.
According to Search Engine Watch (http://www.searchenginewatch.com) – 625 million searches are performed every day!
The great thing about search engines is they bring targeted traffic to your website. These people are already motivated to make a purchase from you- because they searched you out.
With the right website optimisation, the search engines can always deliver your site to your audiences.
