If the website is Flash only, you should add some non-Flash pages which cover the key information held in your Flash website (e.g. contact details, what you do). This is crucial for search engines and accessibility. You may find many users prefer to use this less flashy, but more functional website if given the choice. We strongly discourage Flash-only websites for most purposes. A website should not require the user to download Flash to use the website. Flash is widely installed, and the majority of users who do not have Flash are unable or unwilling to install it, so insisting upon this only loses those visitors, including: iOS users (iPad, iPhone, iPod touch) Most mobile device users (very few smartphones currently support Flash) People who have Flash/advert blocking software installed Users who's IT department prohibits Flash for security The correct approach is to use Flash detection silently, to display Flash content where possible, but otherwise substitute it for a non-Flash equivalent.
