Some of the major disadvantages in using Flash Banners for website design software are the search engine behavior and the usability factor. Flash doesn’t offer much opportunity to give the user personal input. With Flash, the user spends a great deal of time just sitting and watching the load bar when dialing up and it takes a considerably long amount of time to download. In some older versions of Flash Banner designs, the back feature is not usable. You don’t return to the previous page, instead you go completely out of the website. Also, you cannot choose your font size. As website design software goes. Flash ranks very low on the search engines.
