only thing i recall was a guy said if you rename all your pages to .txt instead of .html then a lot of these sites will not recognise them as pages they need to automatically add advert code into or popup adverts when accesses. txt loads as a normal webpage if it has all the righ code in it. this was for a different site and if YOU have to put the adcode in yourself obviously your stuck with it.
