Although Flash websites look flash they can be detrimental to your internet marketing efforts. Here are the top 5 reasons why you should avoid designing a Flash based website:
1. Flash requires a proprietary plugin meaning it does not work with older browsers that are not bundled with Flash.
2. Flash generally does not let users change font sizes or contrast settings using personalized settings.
3. Flash sites often do not have a working back function. Most users are used to being able to back-out of a site.
4. Flash doesn't provide a standard way of navigating without the mouse.
5. Flash is not easily indexed by the search engines.
