What Are Flash Animations?
First, let’s see what the structure of a Flash file is. When you create an animation, you get a file, named, for example, banner.fla. The “.fla” represents the Flash format extension. In order to display this file in a web page, you need to export it in Shockwave Format (extension .swf). It is this file, once exported, that you will be using for your web site. If the animation you have created contains text, it won’t be taken into account by most of the search engines, as they don’t pay much attention to this format. Still, there are search engines (e.g. Google, dir.com, FAST Search) that know how to read the text inserted in the Flash animations. A web page (or even a site!) that is built entirely in Flash will therefore pass almost “unseen” by search engines, which index, almost exclusively, text content in HTML format. Nevertheless, the HTML file that launches the Flash animation will be crawled by search engine’s spiders. Why Use Flash for Sites? It is not a secret for anyone that
