Quoted from Yelobird:I always suggest going to the market place and select "Achieved Ads" and see what Actually sold. Look at those ads as compatibles to what your game looks like and how its configured/quality/addons/upgrades etc and subtract some value for some of the issues you Know are wrong with your game. Just a baseline but Actual sales are a fair barometer in my view. Granted the Current market World issues may deviate that normal. Good luck.
"Archived Ads" also works too.
