Just wondering how to fix this problem: I have 90 different domains, those domains are fysically parked and point to one 'real' domain. The content of those sites is really different because my script detects what domain is asked for. So if i put the ad_network_ads.txt and the .php on the main domain it's also on the other domains. Should I expect problems with the network when using those 2 files for all the domains (and the 90 different accounts I'll have to make for this network?)
I don't have the answer to your question, but your network of sites sounds )*kinda* spammy to me.... just curious what's one of your domains?
No, it should be fine... and actually preferred to do it that way (a single ad_network.php setup) so you aren't making 90 queries per hour to the ad server, and still just one.
Sites are travelindustry related, a different domain for each country. Not spammy, just easy maintainence Perefect! Will do that.
