You go to Google or Yahoo!, but your site is no where to be found!!!
Here is an example, take a minute to visit the homepage for the Bill Murray’s last movie, The Life Aquatic With Steve Zissou, you can find the web site at http://lifeaquatic.movies.go.com The site is great, fun, everything you want in a web experience, but it is invisible. Google’s cache for the site is blank (I checked on April 20, 2005).
The vast majority of visitors to this online retailer never scroll down to see this key-word laden message, but search bots do.
Try this on your own invisible web site and good luck with you online marketing.
