Hi, Rob Miracle posted a blog about switching to another ads network should there be a problem to the initial one, thank you Rob for that helpful guide. I have already tested AdMob and Vungle and they work just as expected. I’d like to know if it’s recommended to have more than 2 Ads networks for switching. I’m programming for Android and Inneractive and CrossInstall can also be used. Would it make much of a difference if I added these 2 or I’d just stick with Admob and Vungle as they’re both considered the best. I haven’t found any answers on this. Thank you very much.
Well, it really depends on your fill rate. I’d be half inclined to stick with the two you have, but modularise as far as possible your advert code so that you can change it once-for-all if there are problems.
Thank you Sir, I will follow your advice
