phpAdsNew is great software if you configure it correctly and use it properly.
It is easy to mess things up, though. It's so flexible you can tie yourself in knots.
One thing to remember - it's campaign driven.
Advertisers are logical groupings of banners/links. Advertisers have Campaigns, and Advertisers have banners. Now, thsoe banners go into Campaigns for the Advertiser. Simple, right? hehe - sounds easy enough.
Publishers are simply where the banners go. I use each web site as a Publisher. Publishers have zones. Zones are simply where the banners will show up on a web site.
Here's the trick - When you add a banner to an advertiser, then subsquently add it to a campaign, then place the campaign in zones, possibly across multiple publishers, the aggregate view and click ratios are calculated. To make things worse, if you reuse the same banner in a seperate campaign, the probability of that banner being shown again is all messed up.
The only way to use phpAdsNew and keep all the math right is to duplicate the banner and add it to a NEW campaign for each publisher you want to run it on.
We did 3,351,328 ad views yesterday on one ad server, and 1,304,294 on another (two installs on the same server platform) so I know it's robust as hell and capable of serving a LOT of ads
Want a performance tip? Convert your database tables to INNODB. It will triple the performance immediately. Also, don't use verbose mode for Stats - use Compact. Try to stay out of the Admin area during peak times, and definately stay out of the Stats until you hit your low traffic point of the day.
