Why do you need a Search Engine Optimization Firm? 
The answer is simple.  You need an SEO Game Plan.  Search engines have complex sets of rules and algorithms that help determine which sites are shown at the top of search results.  While Yahoo! , Google and MSN keep their formulas for determining search results a secret, how they crawl the web and choose what to display is  NOT a complete mystery.  

The core elements of determining search results are easily identified.  Understanding these elements, and properly implementing best practices of Search Engine Optimization will help you increase your site rankings.  Good SEO helps create a better user experience, putting the right content in front of the right audience.  Those that perform SEO have a competitive advantage over those that don’t.
