How to promote the application in the English-speaking Internet

Hello everyone
I am a newbie in advancing applications. Previously engaged in the promotion of sites (SEO) in Moscow region. Now I’m promoting one app in google Play, This game (MMORPG) is available in android, PC and in futher will be on ios.

The English market (and English-speaking audience) is new experience for me. And I really do not know where to start. Problem, but not very big, it is my English level. I can not read a huge amount of information and look for something useful and interesting. It will take a very long time.

Please tell me the most useful websites, blogs, maybe some articles about game apps promotion. What services do you use, what kind of models is the most popular? (CPI, CPA, CPC). What types of advertising effective? I need more links!

I hope you can help me. Thanks in advance.*
