Many good games never get a chance to shine because nobody finds them. There are simply too many games in the Google Play store already. So how do you make your game visible?

I can recommend you thousands of links of mobile marketing companies and all of them will have some important information and interesting tips. But in fact it's not that hard. The most important way of discovery of games is searching the Play store.

First start by asking yourself a question: 

How would I search for my game if I'd like to play it?

So let's say you created a tower defense game with a fantasy theme. Obviously you are targeting tower defense games fans and people who like fantasy genre. So if I was searching for this game, I'd type: "Fantasy Tower Defense" or "Tower Defense Fantasy". And because people with Android phones prefer free games, I might also add "Free". Go ahead and do the search. Do you see any pattern?
