A marketing agency isn't working when results stop being provable, not just when results feel slow. The clearest signs are senior staff quietly disappearing from your account, reports full of vanity metrics with no attribution, no new ideas without being asked, missed deadlines becoming normal, and nobody able to explain which channel actually drove a sale. One or two of these can happen in a rough month. Three or more, especially attribution going missing, is a pattern worth acting on. A working agency proves cause and effect: this channel produced this result, at this cost. When that proof stops arriving, the relationship has moved from partnership to invoice.
The seven signs, at a glance:
- Your senior contact has vanished
- The reports are full of vanity metrics
- No new ideas unless you ask first
- Deadlines start slipping and nobody flags it
- Nobody can explain what drove the last sale
- Every call reviews the past, never proposes the next move
- The invoice goes up, the output doesn't
Sign 1: Your Senior Contact Has Vanished
The person who sold you the account and the person running it should not be strangers to each other. If your senior strategist has quietly turned into an email signature, that's sign one.
Agencies pitch with their best people. The founder or a senior strategist runs the discovery call, presents the plan, wins the trust. Then the account gets handed to whoever is junior and available. That is a normal handoff in a healthy agency, as long as the senior person stays visible: reviewing strategy, showing up on calls that matter, catching mistakes before they cost money.
The problem is when the handoff is total and permanent. You email your original contact and get a "looping in Jamie from now on." Jamie is capable, but Jamie wasn't in the room when your goals were set, and nobody senior is checking Jamie's work. This is how strategy drifts from what you agreed to what's easiest to execute.
Ask directly: who reviews this account weekly, and how often do they touch it themselves? A vague answer is the tell.
Sign 2: The Reports Are Full of Vanity Metrics
A report that leads with impressions, reach, or engagement rate and stops there is not measuring your business, it's measuring activity. Vanity metrics feel like progress because the numbers go up. They rarely explain whether the up went anywhere.
Impressions and reach describe how many people saw something. They say nothing about whether those people bought, booked, or signed up. An agency that reports on activity instead of outcomes is either unable to connect the two, or hoping you won't ask.
A working report ties spend to a specific result: cost per lead, cost per sale, revenue by channel, retention by cohort. It should look uncomfortable in a bad month, because a real number can go down. If every report is a highlight reel, that consistency is itself the red flag.

Sign 3: No New Ideas Unless You Ask First
A working agency brings you the next move before you have to ask for it. If every new test, campaign, or angle only happens because you pushed for it, you are doing the strategic thinking and paying someone else to execute it.
This one is subtle because the agency is still "doing the work." Ads are running, posts are going out, the retainer is being fulfilled to the letter. What's missing is proactive judgment: flagging that a channel has plateaued, proposing a new creative angle before performance drops, testing something because the market shifted, not because a report told them to.
Some of this pattern traces back to how agencies get built in the first place. Overpromising at the sales stage and under-resourcing delivery afterward is a documented failure mode, not just bad luck; see why agencies over-promise and under-deliver for how that gap forms. An agency running lean on strategic time will always default to maintenance over initiative.
Sign 4: Deadlines Start Slipping and Nobody Flags It
One missed deadline with a heads-up and a fix is normal business. A pattern of missed deadlines with no warning, no explanation, and no plan to catch up is a resourcing problem you're paying for.
The specific deadline matters less than the pattern around it. Did they tell you in advance, or did you notice after the fact? Did they explain why, or just apologize and move on? Is the next deadline also at risk, or was this genuinely a one-off?
Agencies that are overextended, whether from taking on too many clients or understaffing the ones they have, tend to go quiet rather than communicate. Silence before a deadline is worse than a late delivery with a warning attached. If your check-ins have started feeling like you're chasing status updates instead of receiving them, that shift in who's doing the following up is the actual sign.
Sign 5: Nobody Can Explain What Drove the Last Sale
Ask a direct question: which channel, campaign, or piece of content led to your last five sales, and what did each one cost to produce that sale. If the honest answer is "we're not sure," attribution has broken down, and everything downstream of it is guesswork.
This is the single most diagnostic question you can ask, because it cuts through every other metric. An agency doing the work should be able to trace a result back to its cause, at least approximately. That's what "we deliver what we said we would" actually requires in practice: not a promise made at the pitch stage, but a receipt produced every month after.
If the answer is a shrug, or a pivot back to impressions and reach, you've found the gap between what's being reported and what's actually happening in your business.
Sign 6: Every Call Reviews the Past, Never Proposes the Next Move
A status call that only recaps last month, with no proposal for next month, is a maintenance call dressed up as strategy. Strategy looks forward. Reporting looks back. A working relationship does both, every time.
Recapping performance is necessary, but it's the floor, not the whole meeting. A working agency uses the recap to justify a specific next step: increase budget here, cut this underperformer, test this new angle, because the data points that way. If your calls consistently end with "same again next month" and no proposal attached, the strategic function of the relationship has quietly stopped.
Sign 7: The Invoice Goes Up, the Output Doesn't
Retainers increase for real reasons: more scope, more channels, more complexity. A retainer that increases with no corresponding increase in output, reporting quality, or results is a price increase disguised as growth.
Ask what specifically changed to justify the new number. More deliverables? More strategic time? A named new service? If the honest answer is "cost of doing business" with nothing new attached, that's not a partnership scaling with you, that's a vendor testing what you'll tolerate.
What to Do If You Count Three or More
One sign is a bad week. Three or more, especially Sign 5, is a pattern. The fix isn't necessarily firing your agency on the spot: it's asking direct questions, in writing, and giving one clear cycle to see if the answers change.
Ask who's senior on your account and how often they touch it. Ask for one month of reporting that ties spend to revenue, not impressions. Ask what's being proposed for next month before the call, not during it. If those answers don't come, or don't hold up, that's your answer.
If you're weighing whether to have that conversation at all, the questions to ask before you actually end the relationship are their own checklist, worth working through separately: how to fire a marketing agency walks through that breakdown.
A working agency should be easy to hold to this standard, because it's already operating that way. If you want to see what that looks like from the outset, the starting point is a digital marketing agency in London built around exactly this: proof, not promises.
FAQ
How do I know if my marketing agency isn't working? Count the signs, not the vibe. Missing senior attention, vanity-metric reporting, no proactive ideas, slipping deadlines, and no clear attribution between spend and sales are the five most reliable indicators. One or two can be a rough patch. Three or more is a pattern.
What's a red flag in an agency report? A report that leads with impressions, reach, or engagement rate and never connects them to a sale, lead, or booking. Vanity metrics can look impressive while telling you nothing about whether the spend worked.
Is it normal for agency account managers to change? Some handoff from senior to junior staff after onboarding is normal, as long as a senior person stays visibly involved in strategy and review. A total, permanent handoff with no senior oversight is not normal, it's a resourcing shortcut.
How long should I give an agency before switching? Give one full reporting cycle after raising the issue directly and in writing. If the same problems repeat with no honest explanation or change, that cycle is your answer. Don't wait through repeated cycles hoping it self-corrects.
What should I ask before firing my agency? Ask for a straight answer on attribution (what channel drove your last sales), a clear account of who's senior on the account, and what's specifically being proposed for next month. Their answers, or lack of them, usually make the decision for you.
What does good agency reporting look like? Good reporting ties spend to outcome: cost per lead, cost per sale, revenue by channel, retention by cohort, reported consistently even in a bad month. For the full standard, see what a marketing agency should report on.
