From other posts it appears that *every* page on the site (or at least what the code can find) must have the ad_network code on it. This is quite a challenge for some html sites that might have hundreds of pages. But nothing a "search & replace" in Dreamweaver can't accomplish. Still, is it necessary that *all* pages of a site have the ad_network code on it to be validated? But I can't even get an add to display on a single page of my site (I don't have the code on all the pages... yet). I have some other php code running on the page so I know parsing should not be an issue. The ad_network.txt file is also being written too. Basically - no ads are displayed and there are no error messages on the page. I see this as an *awesome* tool for link reputation and building PR! But I can't get it working.
