What's changed?
AdBrite's CPC auction used to work such that an ad with the highest bid won. Now, the system takes into account each bid, as well as each ad's clickthrough ratio. In other words, an ad that has a low bid -- but many clicks -- could be shown instead of an ad with a high bid but few clicks.
Why the change?
Showing ads with a higher clickthrough ratio means that we're showing more relevant ads -- and everyone likes ads that are more relevant.
A side-benefit is that CPC prices may drop while targeted click volume increases. As usual, we only charge you the *minimum* amount to appear on a site, just 1-cent CPC higher than the ad you beat out. And, of course, we'll never exceed your maximum CPC or daily budgets.
If you're an advertiser with campaigns running right now with AdBrite, this upgrade may (or may not) affect your campaigns. If your CPC and/or click volumes change, this is why.
What else is new?
