Pretty sure that refers to how they distribute your daily budget, by either providing the impressions ASAP or spreading them out throughout the day based on your daily budget (ie. like facebook).
Bingo. ASAP spends as soon as the impressions are available. Evenly will break up your daily maximum spend into 24 chunks (1 for each hour) and it'll try to spend your $ evenly throughout the day.
What kind of Ads perform better AIB compliant or the Facebook type ads? And what is the difference in pricing? I am thinking about running an AIB campaign but don't know where to start my bids
I think size is irrelevant if you've got a good quality ad targeted at the right demographic. Generally speaking though, the IAB's do get higher CTR's. The IAB's cost a bit more CPM b/c they take up more real estate on the page (~$0.15-ish more than the 110x80's). Lastly, about 70% of our traffic is allocated to the 110x80's and 30% to the IAB's.
Random tip: Cheap traffic in the UK and Canada right now, so that might be a good place to test (ESPECIALLY if you have a successful US campaign already running, why not just find a similar offer and roll them over into the UK and Canada?). Volume-wise, UK+Canada has about the same impressions as the US.
Feel free to email me ben@pof.com if you'd like to see the media kit (breaks down our traffic pretty nicely).
