Well, I've figured out this much with a friend's help, and I'll share it just in case it could help someone else: You can use google to search a site for any particular keyword, like this:
keyword site:domainname.com
The only problem with this: some of the pages of the site may be excluded from search by the robots.txt file .... so I'm still stumped for a solution to do this more 'automatically'...
Another thing I've found that says it will search keywords in a site is a site download software called Teleport Pro... we'll see how it pans out
THANKS!
Fyrflygrl!
