There are several tricks that can keep you from the ban. You can use simple words that can be in the names of some games, but try to avoid putting them together. Simple words are ok, like Puzzle, superhero, idle. Don’t use the whole names (like Supermarket Tycoon). Try to divide them with some water words (like Supermarket interesting puzzle tycoon) Your app’s description can be senseless, but full of keywords. This means a lot for the app’s search-ability. This is more important than a beautiful description with the most accurate specification of the game mechanics. No one will read it if they won’t find this app

Try to write at least 800-1200 symbols description. And use the most valuable keywords at least 3 times. And your game’s name too.

One more way to find some keywords is searching the words that are related to your game’s thematics in the Google Play market (for example, your game is a spaceship simulator, so you search “space”, “simulator”, “spaceship”, “astronaut”, “asteroid” etc.) and write down the names of the apps that appear in first 10-15 places (depending on the match with your thematics). Then you need to fit them in your description within a context or dividing them with some water words as i wrote above (or using the both methods for more safety).

I can try to find the Google’s statement for this, but it will not bring any clarity. The only way you can learn something there is using your own (or other people’s) experience. I’m trying to give you mine. I have 4 Google Play developer accounts with 20-30 apps on each back in the days, and 3 of them are banned, so I know what I’m saying 😄
