Extremely low home recommendation play through rate

Im currently getting around 5.5k ish home recomendations but the Unique user qualified play through rate (recommendations) is EXTREMEMELY low which means nobody is really joining the game off of them.

As of yesterday the play rate is 0.07% which is super low. Im sure its something to do with thumbnail or the player count but im not sure if i should continue ads on the game or stop?
