I'm not positive, as I am not the developer, but have used some of his other scripts before.

I assume it takes your key word/phrase and queries selected search enhgine(s), then spiders those sites looking for specific text (i.e. googlesyndication.com) that is in the code. If the site does have the specific code, then it queries Alexa and Google PR to determine those stats.

But that's just a theory...
