Recently, web designers from the UAE to the US have been raving about flash. Flash is a software developed by Macromedia. It is used to display animations, navigational interfaces, and graphics in a website. many web designers like to use flash because it is very visually attractive and entertaining to the visitors.
What most fail to consider are the cons of producing a website using flash. Because flash based websites are not rich in content they are usually hard to find by search engines. So if you are building a website which you intend to be found by visitors using search engines, limit flash on some parts of your website.
According to a survey, visitors usually stay in a website for an average of 30 seconds. Your visitors would need to find what he/she is looking for in the shortest possible time. Keep in mind that flash based websites often tend to have a higher loading time.
The bottom line is if it is very important to impress visitors with visual presentations, then flash is a must. But if you need more visibility on the web, go for a simple content based website.
