this weeks newsletter?

The newsletter ended with...

To prevent this you can use "Agent Delivery", "IP Delivery" and "Page Cloaking"..... etc. etc.

Can you SEO guys explain what this means, or point me to some resource sites.

thanks

That's one of those things where, if you have to ask, you definitely don't want to mess with it.

Basically, it's the use of scripts that show one page to the spiders, and another to the surfer.

Some people will say there are legitimate use of such scripts, but, in general, the SE's don't agree.

Using them requires a wholesale commitment to blackhat seo, with all that involves.
