Ask Why does increasing your ad spend not always produce results that match how much more money you put in?

[Newman]

Doubling your ad budget does not always double your results because advertising does not work in a straight line. When you increase spend, your ads start reaching people outside your original target group, and those new people may not be as interested. The best-performing audience gets used up quickly, and the next group converts at a lower rate. Ad platforms also become more competitive when you push more money through, which raises your cost per result. More money helps, but only up to a certain point with a specific audience. What do you think businesses misunderstand most about scaling their ad budgets?
