I don’t have a concurrent player base, since my game dies with no ads, but on this game here:
I spent about 900 robux on different forms of advertising over 2 weeks (mostly on weekends), and I got the following results:
First of all, the game has to have potential for players to stay in the game for a little while. For my game, players would either leave within 10 secs, or stay for 15 mins to 1 hour. Try to get players to stay for a longer amount of time, since it can help you get more concurrent players.
Next, IF YOUR GAME ICON IS FLASHY ENOUGH, I recommend sponsorships over ads. My sponsorships used the following icon:
Thanks to the amount of bright color and the clear showcase of danger, an ad like this can drag in players fast. I would recommend making your game icon somewhat colorful and exciting, as long as it fits the theme.
Continuing on the topic of sponsorships, they can show up on any device, unlike ads which only show up on PC. You can also customize who the sponsorship will be shown to, for example: Any gender, 13+, PC and Mobile. This will help you reach your targeted audience more effectively, by targeting the specific type of person you think will be most likely to click into your game and play for a while.
In terms of how much you are spending, I spent around 900 robux over two weekends and managed to get the following results:
When using ads around May 4th, I only reached around 15-20 players a day. When using sponsorships that weekend, though, I managed to hit upwards of 75, and then over 100 the following weekend. I didn’t spend enough to get a concurrent playerbase, but did have at least one player online a good 50% of the time I was advertising. I’d say 400 robux will get you upwards of 100 players, as long as you are using sponsorships with a flashy icon on weekends.
That brings me to my final point, weekends. If you advertise in summer, it won’t be as big of a decrease, however weekdays (monday-friday) have significantly lower ad success compared to saturday and sunday. I recommend putting extra money in on weekends, since there are more players available to reach.
That’s about everything I managed to gather from my experience with ads. My game has 365 visits total as of now, with those coming from 280 total DIFFERENT players, and this was done completely off of ads. If you can get your game on a YouTube video with Flamingo or KreekCraft or something, you shouldn’t need to waste money on ads, but if you don’t have access to that, sponsorships are the way to go, in my opinion. You get more players from different devices. However, if you are only targeting PC users, you can consider buying out some ads too, since you can explain what your game is in a much easier way.
I just played your game a few seconds ago while writing this, and I was too scared to stay for 10 secs, but based off the fact that it’s a dark, horror experience, I would recommend sticking primarily with computer, since these types of games are best experienced with good hardware, and if you use sponsorships, aim them at 13+ so that you don’t hit little, scared kids. I don’t know your budget, but see if you can bend the amount of money you have at your disposal to fit these guidelines. I hope this comment helps you make your game a success! Good luck!
