I have 13 android apps on Google Play store where some have been around since 2009. I am currently monetizing the apps using Axonix (formerly Moblix) with in app advertising banners but making next to nothing. I have 14,923 active installs for the apps in total and looking at statistics I am getting traffic increasing over time. I have done some facebook advertising but most of the installs are from users searching on Google Play. Apart from using Axonix is there a better way to monetise my Google play pages or the apps themselves, i've tried Admob too but its not much better. Attached is the revenue from Axonix in the last month. Thank you for your time.
