Any ideas to get Google to ignore pages depending on a GET variable ?

Would somthing along the lines of this work in robots.txt ?

Yeah that should work. That would be the best way to do it too, With a bots text file.

You might also want to consider putting a noindex meta tag in the pages you don't google to index.


Any other method (user agent or IP) might get you into trouble.

I'm trying to keep search engines out of the sites search on specific modes for the purpose of reducing load, so anything that requires the bot to actually fetch the page to make work isn't what I'm looking for.

I need to review all links to the search & make sure there's nowhere that the order of variables would differ, then I'll try the ~bots.txt

You know, now that I think about it, I may need to review my rel="nofollow", I could have sworn I marked any links to this resource in that mode with them.
