Besides in-app payments, chrome webstore offers monetization with ads - i have read this from article: http://www.marketjs.com/blog/Making-money-with-HTML5-games There is said about ad networks: the good choice is adsense or ad4Game. Anyone has experienced with ad4Game? Is it possible to use clay.io as ad network? Which one is better and are there good alternatives for desktop browser game? In developer program policies https://developers.google.com/chrome/web-store/program_policies?csw=1 i don't understand one thing: Does it mean, that i can use ads only for advertising my another games or links of my ported games to appStore, googlePlay, etc. No ad networks?
