How do I know if my marketing is working?
Most marketing reports answer a narrower question. Five numbers from your own records tell you whether the spend is producing customers the business can afford.
Your marketing is working if you can show, from your own books, that it produced new customers at a cost the business can afford, and that those customers stay long enough to pay that cost back. If the only evidence available is clicks, impressions or leads, you do not yet know.
It is the question almost every owner and executive eventually asks, usually after a year of steady spending and a stack of monthly reports. The reports are rarely wrong. They are simply answering a different, narrower question: how did the activity perform? Whether the activity produced profitable customers is a question about the whole business, and it can only be answered from the whole business's records.
This article sets out a test any leadership team can run with information it already holds. It takes an afternoon, needs no new software, and usually settles an argument that has been going on for months.
Why the usual reports don't answer the question
A typical marketing report is built from the platforms where the marketing runs: the ad accounts, the website analytics, the email tool. Those platforms are accurate about what happens inside them. They can tell you how many people saw an ad, clicked it, and filled in a form. They cannot see what happened next, because what happened next took place in your inbox, on your phone, in a quote, and eventually in your accounting system.
That is not a criticism of whoever prepares the report. It is a structural limit. The people closest to the activity measure what they can see, and the step that matters most to the business, the moment a stranger becomes a paying customer, sits outside their view. So the report fills up with numbers that are easy to collect and stays silent on the ones that decide the budget.
What most reports show
What answers the question
The five numbers that answer it
Each of these can be produced from records your company already keeps. None of them depends on a dashboard.
- New customers in the period. Count them from your invoices or your accounting system, not from the ad platform or the CRM. A new customer is someone who paid you for the first time.
- Everything you paid to win them. Media spend, agency and vendor fees, software, content production, and the share of your team's time that goes into winning new business. Divide this total by the first number and you have your real cost per new customer.
- Where those customers came from. As far as your records allow. Trace each new customer back to their first inquiry and how they found you. Where the record is missing, ask them.
- What a customer is worth. The gross margin a typical customer produces over the time they stay with you. This is customer lifetime value, calculated from your own history rather than an industry average.
- Payback. How many months of margin it takes to recover what you paid to win a customer. This is the number a CFO cares about most, because it determines how much growth the business can fund from its own cash.
If your team can produce all five, you can answer the question. If one of them cannot be produced, that gap is itself the most important thing you have learned, because it means decisions are currently being made without it.
How to read the result
Once the numbers are on one page, they tend to fall into one of three patterns.
The cost of a customer is well below what a customer is worth
Marketing is working. Payback falls within a period your cash flow can carry, and the question shifts from whether to spend to where the next dollar should go. This is a good position, and it is also where many companies under-invest, because nobody has shown leadership the numbers that would justify spending more.
The cost of a customer is close to, or above, what a customer is worth
At current performance, growth is costing more than it returns. The natural reaction is to blame the channel or the agency. Often the cause sits further along the system: inquiries that wait days for a reply, quotes nobody follows up, or customers who leave before they have paid back the cost of winning them. Cutting the marketing budget in that situation treats the symptom.
The numbers cannot be produced
This is the most common outcome, and it is not a failure of the marketing. It means the company's ability to measure results is the part of the system holding everything else back. Until it is fixed, every budget decision is a judgement call presented as analysis.
A figure that cannot be traced to an invoice is an opinion with a chart attached.
When the answer depends on what happens after the inquiry
Marketing creates demand. Whether that demand becomes revenue depends on everything that happens afterwards: how fast someone responds, how the conversation is handled, whether a quote is chased, and whether the customer stays. Together these form what we call a growth system, and in most companies one part of it limits all the others.
This is why the question "is my marketing working?" often has an uncomfortable answer: the marketing is producing exactly what it should, and the business is losing it further down the line. A company that receives plenty of inquiries and answers them three days later does not have an advertising problem. It has a conversion problem that more advertising will make more expensive.
What to do this month
You do not need a consultant to take the first step. Three actions will tell you most of what you need to know.
- Count your new customers for the last twelve months from your invoicing system, and list them by month.
- Total every cost of winning new business for the same twelve months, including fees and the time of the people involved.
- Put the result next to your marketing reports for the same period. Where the two tell different stories, believe your books, and ask why they differ.
The difference between the report and the books is rarely random. It usually points straight at the part of the system that needs attention first. Finding that part, with evidence, is what our assessment is designed to do.
Not sure what your numbers would show?
A fifteen-minute call is enough to tell whether there is a system question worth answering. If there is not, we will say so.

How long should I wait before judging whether my marketing is working?
Long enough for a typical inquiry to become a paying customer. For most service businesses that means looking at six to twelve months of records rather than a single month. Judging a channel faster than your sales cycle mostly measures noise.
Is cost per lead a good measure of marketing performance?
It measures one step, not the outcome. Cost per lead can fall while cost per new customer rises, for example when cheaper leads are a poorer fit and fewer of them buy. Use it to manage a channel, not to decide whether marketing is working.
What if most of my new business comes from referrals?
The same test applies. Record where every inquiry came from at the moment it arrives, count which ones became customers, and include what referrals cost you in time and relationships. Referral-heavy companies often find their paid channels are judged harshly and their referral engine is never measured at all.
Should I ask my agency to prove that marketing is working?
You can, and a good agency will welcome the question. The evidence should still be reconciled with your own records: ask for their reported results to be matched against the customers in your invoicing system for the same period.
