I gotta site going back a few years now which has a few hundred cgi generated pages.

These pages were not created for Google to spider, but all of a sudden I'm getting hits for them and they're showing up in the serps.

I was considering changing them all to html pages in order to get Google to find them, but it seems that Google upgraded before I did.

Are cgi pages a new thing with Google? And is it a bad thing that the site (in Google's eyes) has more than doubled in the serps overnight?

Maybe I should insert a robots.txt ?
