Website Audit

Context: How appealing is the layout and design? Does the site have a contemporary look and feel? Is it easy to navigate?
Content: Is the content attention-grabbing, informative, etc. (text, pictures, sounds, video, etc.)
Customization: Can the website be tailored to different users?
Communication: Does the site support Site--user; user--site communication?
Connection: Is the website linked to other relevant websites for the brand?
Commerce: Does the site support sales?
Change: Does the content change regularly (so people will return)?
Community: Does the website support user-user communication? User-social networking sites?
Contagion: Can users send content/links to other users (aka viral marketing)?
Engagement/Fun: Is the website an engaging place to spend time?
