How much did we spend?
The total, how it changed and where the money was allocated.
Can you trust your agency reports?
Do not blindly trust an advertising report you cannot understand.
You do not need to assume your agency is dishonest. You do need enough independent visibility to understand what was spent, what was tracked and what deserves an explanation.
The balanced position
Trust should be supported by clarity—not replaced by suspicion.
Most agency relationships are not a simple choice between complete trust and complete distrust. An agency may be skilled, honest and still produce reports that focus on platform metrics rather than the financial reality of the business. A business owner should be able to verify the story without becoming an advertising expert.
A useful report should answer
Six questions that matter more than a colourful PDF.
What meaningful result was tracked?
Purchases, qualified leads or another agreed business outcome—not only clicks or impressions.
Was the result commercially acceptable?
Performance compared with the target return, margin or acceptable acquisition cost.
What improved or declined?
A like-for-like comparison with the previous period and an explanation of the main causes.
What is being tested?
The creative, targeting, keyword, landing-page or budget changes being evaluated and how success will be judged.
How reliable is the conclusion?
The amount of data available, tracking limitations and any attribution overlap that could affect the answer.
Reporting gaps worth questioning
These do not prove wrongdoing. They do deserve an explanation.
Only flattering metrics are highlighted
Reach, impressions and clicks may have improved while the cost of a sale or lead deteriorated.
Tracked revenue is presented as certain profit
Platform attribution does not account for margin, refunds, repeat customers or duplicated claims across channels.
The report does not compare with an agreed target
A return can look positive while still being below the level your business needs to break even.
Poor performance is repeatedly blamed on “learning”
Learning periods are real, but the agency should define what evidence or date will trigger a decision.
Budget increases are recommended without commercial context
More spend is not automatically good if the account is already acquiring customers at an unacceptable cost.
Tracking limitations are missing from the report
Missing values, duplicated conversions and different attribution windows can materially change the story.

Example meeting brief
Three things to discuss this month
- £1,280 spent without a tracked purchase.Ask what these campaigns are intended to achieve.

- Two conversion goals differ.Ask when tracking was last tested and which action is used for reporting.
Frequently asked questions
Questions business owners ask about agency reports.
Does a confusing report mean my agency is doing a bad job?
No. Advertising data is genuinely complicated, and an agency may be producing good work while communicating it badly. The point is to make the evidence understandable so performance can be discussed properly.
What should an advertising agency report always show?
At minimum: spend, the outcomes that matter to the business, tracked value where relevant, cost per result, comparison with an agreed target, changes over time, important tests and any tracking limitations.
Should I judge my agency only by ROAS?
No. ROAS can be useful but may ignore margin, new versus existing customers, lead quality, attribution overlap and the campaign’s intended purpose.
What if my agency says a campaign needs more time?
That can be reasonable. Ask what amount of spend, number of conversions or time period will be considered enough to judge it, and what decision will be made at that point.
