I'm embarking on a new project and one of the stipulations from the client is that the Android app I am designing MUST have banner ads in it but they are also to be put where they will "cause the least amount of irritation". The revenue made from these ads is based on impression rather than clicks so it makes sense to put them where they are least likely to get in the way This made me wonder, is there somewhere to place ads that will annoy users less than if they are placed elsewhere or do users just ignore ads anyway?
I know that this shares some points with web based advert placement but as with all things mobile it has it's own unique problems.
Most apps seem to put their ads at the bottom of the screen, however a fair few put them at the top now too. I know from personal experience that I tend to look over ads and don't really notice them so if I place the ads in these usual places will it cause less irritation to the user? Have users seen so many ads that their eyes automatically skip over them in a sort of mental ad block?
