I host a modification for all ZetaBoards forums called the AiO 2.0 (All-in-One 2.0). This system is used by over 6,000 people and counting! Every single time an AiO user views a forum, it will show them an ad with an affiliate button (88x31). This is shown on every single page of every single forum with the AiO. It is a rotational ad. You can pay by clicks or impressions. For an example of how the system works, here are some of the ads: Victory Road - Added 1 Month Ago - 1,149,960 views - 1,066 hits Forum2Forum - Added 3 weeks ago - 1,105,628 views - 556 hits If you want to advertise a ZetaBoards forum, reduced prices can be found here: http://zbaio.zetabin.com/forum/1656223/ . Otherwise prices are negotiable. I allow any websites that do not offer illegal content, for example warez, libel. I also do not allow pharmaceutical or adult websites. If you are not sure whether your site is allowed or not, run it by me. You can view the live statistics of your advert at any time. This system was added just 1 month ago so the statistics will be rising exponentially. If you want more in-depth statistics, just ask. I only accept payment by PayPal.
As stated by the OP: Every single time an AiO user views a forum, it will show them an ad with an affiliate button (88x31).
