Keyword Research Help

Hi! I make lots of game apps, and wondered what the best way you think is to decide the “theme” of each game?

How do you guys predict what keywords will do well? Personally, I just try to be intelligent about it and look at what else is doing well, but I am sure there is a better, more effective way? :wink:

How to?

Well, I would say the theme totally depends on the app you are trying to create I mean if its a kids app then add Doraemon would make your app go popular among the kids and same continues with all the apps available !
