Thanks for the response.
Yes banner ad appeared on the real device.
Well so far I never used banner ads,they look ugly I hate them,I only use interstitials.but lately I got an email from admob.See image my all income is from interstitals while for similar apps they get only %20 from interstitials and %55 from banners.I think this is because you show many ads with banners.
For banners I am going to use standart banners I think smart banners arent working anymore right?
I am planning to create a new banner at the begginğng of each level and I am going to hide it at the end of the level since at this point there is possibility an insterstital may pop.Is this the right way to implement it?
