How can I make my game Survive! Show up in search results?
I found this article featuring a similar topic, hopefully it can answer your question!
Never use emojis in your game title, the algorithm doesn’t like them, also your game name is too generic
The problem might be is that you used an emoji. It might mess with the algorithm and make it so that every player that wants to play your game have to put in that emoji. Remove it.
You chose a highly competetive keyword as your title, which means that you will have to have a lot of players to rise above existing popular games that are ranking high in results of “survive”. It probably shows up in results, but somewhere below others.
Also emoji is fine and might be good for click-through-rate, search engines ignore them (and I bet ROBLOX does too) and nobody needs to type the emoji to find the game.
