How do you forecast what your ad spend will buy?
Short answer
Use recent cost data, plan for seasonal swings, and separate channels with fixed prices from auction channels. Fixed-rate channels can be forecast exactly.
For auction channels, start from your last few months of CPMs, then add a buffer for peak seasons when costs rise. Forecast a range, not one number.
For fixed-rate channels, the maths is simple: budget ÷ rate per 1,000 × 1,000 = the most views the budget buys. On Pomera, that is the most verified views.
Mixing the two gives you a plan with a predictable core. Read why predictable ad spend matters.
