Most businesses trust a web designer to build a website for them and accept the end result assuming all is well.  Today, I looked at local auto dealer website and noticed that in different browsers the site did not display properly.  Having your site coded properly for multiple web browsers is becoming more and more important as Internet users are being pushed to use Mozilla and Chrome. Make sure that even after your designer has completed their work that you reach out to a company like Accelerated Selling to optimize your site.
