Don't lose your site traffic prematurely.
Great incoming traffic? Check.
Compelling content? Check.
Are your visitors still bailing out on your site after a page or two?
Each page builds a step in your visitor's journey, and as such, needs to have a clearly-defined purpose. Many pages have great content, but don't walk people through the journey. Visitors meet the dreaded Dead End when they are on a page that doesn't hold their hand through to the next step.
