I agree with HunkMoneyLuke and GayGeek. Our sites are primarily social network type sites so we (hopefully) have long relationships with our user base. When they feel they got ripped off, they may request a chargeback, but they're going to give us an earful about it anyway. As far as a lot of our users are concerned, if we promote it, they expect us to stand behind it. So if we start getting complaints, we drop programs very quickly rather than risk tarnishing ourselves. (Understanding that some people won't ever be happy, but sometimes it's pretty clear that they were misled.)

It's also important that people be updating their content regularly. There are quite a few programs that have had the same tired content up for almost two years. (I've really noticed this with a lot of our bisexual programs.)

Good, fresh promo content is great and RSS feeds help us be able to keep it fresh on some of our sites more easily. It may seem like a little thing, but refreshing banners from time to time is a tiny but important thing. There are some programs that haven't changed their banners for two or three years. We sometimes hold and park them inconspicuously now, as a just in case, but they never convert anymore.

Usually things run smooth, but when there is a problem, responsiveness is key. I seldom need anything from the reps or techs, but once a year when something goes wrong, it's nice to get a reasonably quick response.
