STEALTHbuster
Stealth Buster lets you enter a URL and compare how Google sees it versus Internet Explorer. Some web sites employ stealth or cloaking technology that delivers one page to the spider and a different page to the user. According to Google's policies, the company, "...may permanently ban from our index any sites or site authors that engage in cloaking to distort their search rankings."
This little script allows you to examine and compare how a URL delivers content and whether there are any discrepancies. For a great article on cloaking/stealth, read this.
StealthBuster is brought to you by of businesslauncher.com and vexcom web systems.
*Note - This application may not be 100% accurate and there can be many reasons for differences in content length, many that are not considered "bad cloaking" - for example: a flash site with no indexable content may "cloak" the text content of the movie. We are not posing any judgment on the results just offering up the data. Also - there are some clever "cloakers" out there that actually check the IP of the bot to make sure its really google requesting it, so the site you check may appear clean here, but still be using more elaborate cloaking methods...
