Generic words are gonna have too much competition. You need a word none of the most popular games are using. Think of a keyword, search it, if there are no results, or only a few or mostly starter Places with few visits, then it might be a good keyword for your game. Problem is, it has to be a word that applies to your game and that someone might search for or you won’t get a click-through anyway. Also unfortunately it seems to me the search algorithm doesn’t factor in word order or even combinations for multiple word searches(or if it does, it does a terrible job at it), so it needs to be a single unique word.
Search for ‘FBO’ and you’ll likely find my game, but who the heck knows what an FBO is on Roblox? I’ll tell you, not many. Search for ‘airplane’ and you will never find it, ever.
