I'm developing an app which shows location based ads. If you are interested you swipe right, if not, you swipe left.
Initially, in my first prototype of the app I tried an infinite scroll, which turned out to look, in my opinion, very boring and easy to get distracted. Then, I thought about showing a fixed number of ads, I tried it and it turned out to be much easier to focus on those few ads.
By this logic, showing only one ad would be the best since the user can fully focus on that one, but since I'm showing ads, I also want the user to be able to find something they like without having to focus too much on every ad. Also I think that by showing more than one ad at the same time the user may feel they have more options.
My questions are:
Is my premise right? (maybe an infinite scroll is my best choice)
If showing a fixed number of ads at the same time is the best option, would one have the same impact on the user than showing three, or two?
How would I show, for instance, three ads and make sure the user knows that he can be interested on all three, or none? (That he hasn't got to choose a single one)
Here is a screenshot:
