以Flash动画作网站引导页面是不是真的需要呢？(3) What purpose does it serve? 它的目的是什么？
With very few exceptions, Flash intros don't convey useful information; their sole purpose is to act as eye candy. Even if the Flash intro does convey useful information, this is still ill-advised, which allows me to segue nicely to my next point.
Flash 引导页不能传达有效信息，我想这一点没有几个人会反对。其实Flash 引导页的主要目的就是吸引用户眼球。即使能够传达有用的信息，最好也别用，原因请看下点。 Do you want your website to be visible to the search engines? 你想网站被搜索引擎优化吗？
It doesn't seem to be common knowledge but is a very pertinent fact - search engine crawlers do not index Flash nearly as effectively or consistently as they do for regular HTML. If your Flash intro includes important text about your website, it is far better to present this as regular web page content which is readily Accessible.
