Recently I've been trying to make Interstitial on PropellerAds work... but didn't have any success!
While a camp on POP had more than 30+ conversions on as specific budget, the same camp with the same budget (and same lander, same GEO, etc, the exactly same camp) got me only 1 conversion on Interstitial.
I thought that interstitial should have a better conversion, as it shows intent! But no, it was the exactly opposite!
What is your experience on this?
p.s. sorry to post it on Push traffic forum, it doesn't have a forum for interstitial!
I only tested 1 or 2 interstitial campaigns so I can´t tell much about it.
Will follow to see if other users made different/better experiences than you.
