Digital marketing term
Ad Spending
The amount actually charged for ads—not the allocated budget, but what the platform billed. Pacing, channel mix, and return are written against this number.
Detailed explanation
Ad spend is the sum of what you paid per click, impression, or conversion. Budget is the cap; spend is what cleared. Daily pacing spreads that realized amount across the flight. ‘We had budget left’ at month end is a delivery problem, not a savings win by default.
A common mess is mixing VAT, agency fees, and platform charges in one line. If the ROAS or CPA denominator is undefined, channels cannot be compared. Killing spend on clicks alone also cuts the funnel before you see outcomes.
Lock the denominator (media only vs full cost). Pace as remaining budget over remaining days. Judge results on ROAS, CPA, or cost per lead. Cheap clicks are not success on their own.
Frequently asked questions
- Why separate budget from spend?
- Budget is the ceiling. Spend is what billed. Thin inventory, caps, or bids can leave the ceiling unfilled.
- Do agency fees belong in the ROAS denominator?
- Pick one definition and keep it. Mixing media-only ROAS with fully loaded cost makes channels look better or worse than they are.
