The first 90 days with a fractional CMO

The first 30 days establish whether the numbers can be trusted, by reconciling platform reporting to the bank account and reading the account structure. Days 31 to 60 reallocate budget and set the reporting rhythm. Days 61 to 90 give the first honest read on whether the reallocation worked.

Days 1 to 30: can the numbers be trusted

Nothing else is worth doing until the reporting is trustworthy. The first job is reconciliation: compare total revenue as the store and the bank report it, and total spend across every platform, against the sum of what each platform claims it produced. Those views will disagree. The size and direction of the gap tells you how much of the current plan rests on numbers that double count. Then read the account structure: how campaigns are segmented, what is being tested against what, where budget is trapped in structures that cannot spend it, and which conversion events are firing. Expect a diagnosis and a short list of fixes this month rather than performance changes, because changing bids before the measurement is settled moves an unreliable number around.

Days 31 to 60: reallocate and set the rhythm

With a reconciled baseline, reallocation becomes a decision rather than a guess. Budget moves toward what the blended view supports and away from what only platform reporting supported. Some of that is between channels and some is inside a single account, where a small number of structures usually carry most of the efficiency. The second job is the reporting rhythm: a weekly operating review for the team and a monthly review for ownership, both built on the same defined metrics. The third is the creative testing queue, which needs a stated volume and an agreed way of judging results before the first test runs. This sequence is how Plaid Testing’s fractional CMO practice opens an engagement, and the order matters more than the speed.

Days 61 to 90: the first honest read

By day 61 there is enough post-change data to read honestly. The question is narrow: did the reallocated spend produce better blended efficiency at the same or higher volume, and if not, which assumption was wrong. Some reallocations work inside six weeks. Others show that the constraint was never the media buy, and the answer sits in offer, landing page, or retention. That is a real finding rather than a failure, and it is visible only because the first month was spent making the numbers trustworthy. The output of this window is decisions: what scales, what stops, what gets rebuilt, and what the next quarter’s budget looks like with reasons attached. A brand should finish day 90 with a written plan it could hand to somebody else.

Over a longer engagement with a fashion apparel and accessories brand, sales rose 249% and net profit rose 205% year over year with spend scaled 4x. New customer cost per acquisition and new-customer ROAS were tracked throughout, and ownership reporting ran on blended sales and margin.

What not to expect in 90 days

Not a revenue step change. Ninety days is roughly one measurement cycle for a brand with a considered purchase and a returning customer base, and most of the compounding effect of better allocation and a working testing queue lands after it. What a brand should expect by day 90 is more checkable: one number the whole team reports on, a reconciliation between platform reporting and the bank account, a cleaned account structure with reasons written down, a testing queue running at a stated volume, and a quarterly plan with budget allocated by channel. Those are the conditions under which growth becomes repeatable rather than occasional, and judging the engagement on 90 day revenue alone tends to reward whoever spent the fastest.

Before you start an engagement, ask the candidate what happens in the first 30 days. An answer that begins with campaign changes rather than reconciliation is worth noting. Plaid Testing begins engagements with a free thirty minute audit covering tracking, account structure and three fixes, so both sides know what the first 30 days would find before anyone signs anything.
