How much, if at all, should I spend on Advertisements?

I apologise if this is the wrong category to put this in, but I’m new here and don’t really know where to put this question. I’ve been thinking that I should consider making an ad or sponsorship for This Game As of right now, it gets a few visits here and there, which I understand because of how new and unknown it is. But I was wondering - When should I consider advertising, and how much should I spend? Again sorry if this is the wrong category!
