If you're a founder turning over £1M to £20M, you almost certainly have a monthly agency report sitting in your inbox. It's well-designed. It has green arrows. It tells you impressions are up, clicks are up, and engagement is at an all-time high. Then you check your bank account. Revenue is flat. New customer numbers haven't moved. You can't actually tell whether the £15,000 you spent on ads last month produced anything.
01The report leads with impressions, clicks, or "engagement"
Impressions measure how many times a screen flashed your ad. Clicks measure curiosity. Engagement measures whether someone scrolled past your post. None of these are revenue. None of them are leads. None of them are customers.
A real marketing report opens with three numbers: cost per qualified lead, customer acquisition cost, and return on ad spend tied to closed revenue. If your monthly deck doesn't put those three at the top — in plain pounds and pence — your agency is hiding something.
What to demand
Tell your agency you want next month's report restructured. The first page must answer one question: "For every £1 we gave you, how many £ did we get back?" If they push back, talk about attribution complexity, or say it's "not how the platform works", that is your answer.
02They report on platform conversions, not real-world sales
Google Ads will happily tell you it generated 84 conversions last month. Meta will tell you it generated 211. Add them up and you should have 295 new customers. Check your CRM and you might find 12.
This gap is where most marketing budgets die. The platforms count form-fills, button clicks, and assumed conversions based on browsing patterns. None of that is a paying customer. None of it survives a credit-control conversation.
Until your ad accounts are wired directly into your CRM and reporting on closed deals or shipped orders — not platform-side conversions — you are paying for ghosts.
03The "wins" are always at the top of the funnel
Watch how an underperforming agency tells the story. Awareness is up. Reach is up. Brand searches are up. New audiences are being tested. The funnel is being "warmed".
This is the script of a vendor who can't show bottom-line results, so they retreat upstream where everything is harder to measure and easier to spin. A senior operator does the opposite: they protect the conversion numbers first and only spend on awareness when the unit economics are proven.
04What to do this week
- Pull your last three months of agency reports. Find the page where revenue or qualified leads appear. If you can't, that's the issue.
- Open your CRM. Count the number of customers acquired via paid channels in the same period.
- Divide total ad spend by that number. That is your real cost per acquisition. Compare it to what your agency told you.
If the two numbers don't match, you don't have a marketing problem. You have a reporting problem. And until it's fixed, every additional pound of ad spend compounds the damage.
