For easiest, fastest, most detailed and most personalized content: Interactivity!
Interactive applications enable you to have a "user-friendly", "ergonomic" and "to-the-point" web site. Instead of displaying ready and static content pages, interactive applications collect / gather / display information from a database (or several databases) upon user requests. Interactive web sites can collect valuable data from user inputs (even mouse clicks), so you can "measure and benchmark" your online activities, revise your online marketing strategy and its implementation on regular basis.
