First, try to read the general idea.
Now, here’s what you need to do, calculate
(Estimated Impressions) * (CTR) = (Players)
now do
(Budget)/(Players) = (Robux Spent for every player)
(You can also calculate the income per player after by doing (Income)/(Players) how much robux players averagely spend)
If Robux spent for every player is higher than 10, it’s very bad. Would be perfect if it’s 4-6. 2 is impossible.
If Income per player is higher than 0.5 it would be quite good.
Note: I defaultly qualified every who clicked into the ad as a player, but in reality, certain clickers might not join.
