Where should the next marketing dollar go?
First, what's actually holding the business back — if it isn't demand, that's the whole answer. If it is, we rank your channels on what the next $100 is likely to earn, not on what they've earned so far.
Free, and no card. One pair of questions per channel asks for a guess on purpose — a low and a high, not a single invented number.
Informational only — not audit, attest, legal, tax, or investment advice. This is arithmetic on the figures you enter; it is only as good as they are.
Ranking channels only matters once demand is the real limit
Most "which channel should I spend more on" advice skips straight to a comparison table. It assumes the business can absorb whatever demand that spend brings in — more customers, served well, paid on time. That's often not true: a business turning away work already, short on cash, or short on people doesn't need more customers, it needs to fix the thing actually holding it back. This tool asks that question first, and stops there when the answer isn't demand.
When demand is the real constraint, the comparison that matters isn't which channel has earned the most so far — it's which channel is likely to earn the most on the very next dollar. A channel can have a strong track record and still be the wrong place to add spend, if it's already close to tapped out. This tool asks for that forward guess directly, as a range, and flags a channel when the owner's own numbers say it's running out of room.
Frequently asked questions
Why does this ask what's limiting the business before anything about marketing?
Because ranking channels only matters if more customers is actually what the business needs right now. If the real limit is capacity, cash or staff, more marketing spend brings in demand the business can't serve, can't afford to chase, or doesn't have the hands to deliver — so the tool says that plainly and stops, before asking a single question about channels.
What does "marginal return" mean here, and why not just use past ROI?
Marginal return is what the NEXT dollar is likely to earn, not what the channel has already earned on average. A channel can have a great track record and still be the worst place to add spend right now, if it's already close to saturated. Past ROI is still shown, but labelled backward-looking — it's context, not the ranking basis.
Why a low and a high guess for the next $100, instead of one number?
Nobody can know exactly what another $100 will bring back — it's a genuine guess about the future. Asking for a range instead of a single number is honest about that, and the swing between the two ends shows how confident that guess actually is.
What triggers the saturation warning?
A channel is flagged when the owner's own high guess for the next $100 comes in at less than half of what that channel has already returned on average. That's a signal worth a second look, not a verdict — the tool ranks and warns, it doesn't set a budget.
Do I need an account?
No. The constraint check and the full channel ranking are free with no email wall. Signing in only keeps the result so a later run can show you what moved.
