Dynamic Widget Traps
Dynamic widget traps are Flash files, Java applets, and ActiveX controls. All of these technologies are similar in the sense that they provide features that are not usually available within JavaScript, CSS, or DHTML. Be careful when using widgets based on these platforms.
Using Flash
Flash specifically refers to advanced graphics or animations programmed in ActionScript for the Adobe Flash platform. Although Flash is almost always used for animations, sites without animation can be built in Flash, but doing so is a bad idea from an SEO point of view.
Whenever you see online video games with advanced graphics/animation, chances are they were done in Flash. Many web designers use Flash to create their sites. Flash is not a problem in general, but the same rules apply as with JavaScript. If the content you are presenting in Flash needs to be indexed, take it out of Flash. Here is a typical example of HTML source code with an embedded Flash application:
<HTML> <HEAD> <TITLE>Flash Page Example</TITLE> </HEAD> <BODY> <OBJECT classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' codebase ='http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab #version=5,0,0,0' WIDTH=100% HEIGHT=100% id=ShockwaveFlash1> <PARAM NAME=movie VALUE='busi_01_01.swf'> <PARAM NAME=menu VALUE=false> <PARAM NAME=quality VALUE=high> <PARAM NAME=scale VALUE=exactfit> <PARAM NAME=bgcolor VALUE="#FFFFFF"> <EMBED src='flashappABC.swf' menu=false quality=high scale=exactfit bgcolor="#FFFFFF" ...
