The First 90 Days With a Marketing Agency
Short answer
In the first 30 days: an audit, working conversion tracking, agreed break-even numbers and a documented plan. By day 60: campaigns out of the learning phase, several creative concepts tested, and a first honest cost per acquisition. By day 90: a stable structure, identified winners scaling, and reporting that reconciles to your actual revenue. If tracking is still unreliable at day 90, the engagement has not started properly regardless of what the reports show.

Days 1 to 30: measurement and maths before media
The first month should be unglamorous. A competent agency spends it auditing what exists, fixing conversion tracking, establishing what a customer is worth and calculating the break-even cost per acquisition your margins allow. Campaigns may launch, but they are not the point of the first month.
This is also when access and ownership should be settled: ad accounts under your business manager, pixel and conversions API verified, analytics connected to real revenue. Agencies that skip this and launch campaigns in week one are optimising for the appearance of momentum, and the bill for it arrives in month three when nobody can explain what the numbers mean.
- Account and tracking audit with findings written down
- Conversion events verified against your backend orders
- Break-even cost per acquisition agreed from your margin
- A documented plan with what will be tested and in what order
Days 31 to 60: first honest read
Month two is where campaigns should exit the learning phase and produce a cost per acquisition you can trust. Several genuinely different creative concepts should have run, and the differences between them should be visible in the reporting rather than asserted.
You should also start seeing the agency say what did not work. An engagement where every report is positive in month two is either unusually lucky or not telling you about the tests that failed, and the second is far more common than the first.
Days 61 to 90: structure and scale
By month three the account structure should be settled rather than being rebuilt every fortnight. Winning creative concepts should be scaling with budget increases in measured steps, losing ones should have been cut, and a creative production rhythm should exist so the next batch is ready before fatigue arrives.
Reporting at this point should reconcile to your own numbers. If the platform reports revenue that your backend does not recognise, that gap has to be explained before any scaling decision is made on top of it.
What drifting looks like
The clearest sign of drift is reporting that stays at the impression and engagement level past month one. The second is a structure that changes completely every few weeks, which usually means nobody has a hypothesis and the account is being rearranged rather than optimised.
The third is silence about failures. Testing produces failures by design, and an agency that only reports wins is either not testing or not being straight with you. Neither is recoverable by waiting another quarter.
- Still no agreed break-even number by day 30
- Conversion tracking still unverified by day 45
- Complete structural rebuilds every two weeks with no stated hypothesis
- No failed test ever mentioned in ninety days
What should exist by each checkpoint
| Checkpoint | Should exist | Warning sign |
|---|---|---|
| Day 30 | Audit, tracking verified, break-even agreed | Campaigns live but no numbers agreed |
| Day 60 | Out of learning, several concepts tested | Costs still unstable, no creative variety |
| Day 90 | Stable structure, winners scaling | Structure still changing weekly |
| Ongoing | Reporting reconciled to your revenue | Platform numbers your backend cannot match |
Related questions
Should campaigns launch in week one?
They can, but the tracking and margin work matters more. Launching before conversion tracking is verified means the first month of data is unreliable, and decisions made on it have to be unwound later. A week spent on measurement usually saves a month of confusion.
Is it normal to see no results in month one?
Yes. Month one is learning phase and diagnostics. Judging performance then means judging the platform's exploration period, which tells you little. The fair checkpoint for paid media is around day 60.
How often should we meet?
Weekly during the first month while tracking and structure are being settled, then fortnightly once the account stabilises. What matters more than frequency is whether the meeting covers decisions and numbers or just recaps a dashboard you could read yourself.
What if we want to leave after 90 days?
You should be able to, with your accounts, data, creative files and documentation intact. If leaving at day 90 would cost you your conversion history or your creative assets, the ownership terms were wrong at the start rather than at the end.
