Hello, I've ran multiple Google Ads campaign to my game and i get insane number of clicks 800-2k and the conversions are 80-170 a day. Conversions are counted for users who had played for over 8 minutes Wich is very possible since the game is an online social game where you can chat create your house and infinite things to do. Problem I've seen are that 80% of the traffic are kids from 10-13 years old and some can't even write or read, how to avoid this? the audience min age is 18. Users literally exit the game between 30 seconds to 2 minutes in-game. they are either too young to understand or get lost in the wild.
PPC ads are just one way to get customers. Haven't you thought of other ways to market your game? For example, guest posts.
