The short version
The signs your marketing agency is coasting show up in the reporting months before anyone acts: metrics that change definition, deliverables described rather than counted, and a plan for next month that reads like last month’s. The 3 questions at the end settle it faster than an audit does.
Most retainers do not fail dramatically. They drift, and the drift is visible in the paperwork months before it is visible in the results.
These are the signals worth watching, and the three questions that settle the matter faster than any audit.
The signs your marketing agency is coasting start in the reporting
Short answer
The clearest signal is a report whose sections change month to month. When the metric that led last month is buried this month, the report has stopped being a record and started being an argument.
A stable report format is inconvenient for a supplier having a bad quarter, which is exactly why it is worth insisting on.
Watch for new metrics appearing without explanation. Impressions replacing clicks, or reach replacing engagement, usually means the previous number went the wrong way.
When to fire a marketing agency, and when not to
Short answer
Fire a marketing agency when the process has failed, not when a month has. Missed deliverables, reporting that changes shape, and no answer to a direct question are process failures. A flat month with the work visibly done is not.
- Fire: deliverables missed with no notice, twice or more
- Fire: reporting whose sections or metric definitions changed without being flagged
- Fire: a direct question about a decline answered with a list of activity
- Do not fire: one flat month with the agreed work demonstrably delivered
- Do not fire: a decline you can trace to a change you made or a market event
The two look identical on a dashboard and lead to opposite decisions. Channels have flat months nobody controls: a competitor outspending you, a trough, an update. Firing over one is how buyers hit their fourth agency in two years, each dismissed just before its work would have compounded.
What justifies ending it is the process breaking down: deliverables promised and undelivered, a report you cannot compare to the last, or a decline answered with a summary of activity. Those do not improve on their own.
Put the three questions below in writing and treat a non-answer as the answer. Notice period, final invoice and what you keep should already be in the contract; if they are not, that is its own finding.
How to test whether the work is still happening
Deliverables are described rather than counted
Short answer
Healthy reporting says four pages optimized and names them. Coasting reporting says ongoing optimization. The move from counts to adjectives is the single most reliable early indicator, and it usually appears before results decline.
Ask for the URLs. A supplier doing the work will send them in minutes, because they exist.
The same recommendations keep reappearing
- A recommendation from three months ago appears again as new
- The plan for next month is last month’s plan with the dates changed
- Audits are re-run rather than the previous audit being closed out
- Nothing on the blocked list ever becomes unblocked or is escalated
Repetition is not always coasting. Sometimes it is a supplier stuck behind your own approvals, which is why the blocked list matters: it shows whose queue the work is sitting in.
Three things a fixed-scope arrangement states up front
The account gets quieter, then friendlier
Short answer
A common pattern is fewer substantive updates followed by more relationship management: check-in calls with no agenda, a new account manager, an offer of a strategy session. Warmth increasing while output decreases is worth noticing.
None of these are proof on their own. Together, and alongside the reporting signals, they usually indicate the account has been reassigned to someone with less capacity.
You will need to always outrun your churn with marketing. You are not just selling, you are outselling churn every single month.
Why this matters
What questions expose a coasting agency?
Short answer
Three questions settle it: what specifically was delivered last month, what will exist at the end of next month, and what have you stopped doing because it was not working. The third is the one a coasting supplier cannot answer.
A supplier genuinely engaged with your account has abandoned something. If everything they started twelve months ago is still running unchanged, nothing is being evaluated.
If it depends upon you, literally you as the founder, it is not scalable. It is extremely fragile.
Why this matters
The contract does the work the results should
Short answer
If renewal conversations lean on notice periods, minimum terms and what is contractually owed rather than on what the work produced, the commercial relationship has replaced the working one.
This is the strongest argument for monthly billing on both sides. Work that has to earn its renewal every month cannot coast for long without someone noticing.
What to do about it
- Ask the three questions in writing, and give a reasonable deadline
- Request the deliverable list as counts and URLs for the last three months
- Fix the report format for the next quarter and refuse changes to it
- Set one measurable objective with a date, and review it on that date
- If nothing changes, leave. A retainer that needs supervision is costing you twice
Switching costs are real, so it is worth one honest conversation first. Many accounts recover when the supplier realises the client is reading the reports.
The signs your marketing agency is coasting are reporting problems, the way a link report is. The format our own reports arrive in is fixed in advance for that reason, and what each tier owes you each month is counted rather than described.

What to take away
- Reports that change shape are the earliest reliable signal.
- Counts becoming adjectives usually precedes results declining.
- "What have you stopped doing?" is the question a coasting supplier cannot answer.
- Monthly billing makes drift visible faster than any contractual protection does.
