Search this question and you get the same five bullets everywhere. Sets strategy. Owns positioning. Manages the team. Reports to the CEO. Ties marketing to revenue.
All true. All useless if you're trying to work out whether fifteen hours a week is enough to change anything at your company.
So here's a real week instead. This is a fifteen-hour engagement at month three, at a B2B company doing around eleven million with two marketing people and an agency. If you want the definitional version first, that's here, and the governance version, written for explaining the appointment to a board, is in the fractional chief marketing officer guide.
Monday: the two meetings that set the week
08:30, forty-five minutes, CEO sync. Not a status update. Three things on the agenda: what changed in the business since last week, what the marketing number looks like against target, and the one decision that needs making this week.
This week's decision is whether to pull budget from a paid channel that's producing cheap leads sales won't call. It's been running eight weeks. The cost per lead looks great in the dashboard and the conversion to qualified opportunity is close to zero. The recommendation is to kill it and move the spend into the ABM program. The CEO likes the channel because the numbers look good in the board pack. That conversation takes twenty of the forty-five minutes and ends with the channel being killed.
10:00, one hour, marketing standup. Two in-house people. What shipped last week, what's blocked, what's landing this week. The blocked item is a case study waiting on a customer's legal team for eleven days. Action: draft an anonymized version so it can go out while approval grinds on.
Then the content brief review. Three briefs for the week, and one gets sent back because the takeaway is generic. Two hours getting a brief right is worth more than two days editing a draft built on a bad one.
Tuesday: numbers and the uncomfortable conversation
Ninety minutes, pipeline and attribution review. Alone, in the data. Which opportunities created in the last thirty days had a marketing touch, what the first touch was, what the multi-touch picture looks like, and where the CRM data is lying.
This week the finding is that eight of the last twelve qualified opportunities had at least three content touches before the first sales conversation, but attribution was crediting the last-click form fill. That reframes an entire budget argument, and it only surfaced because someone went and looked.
Forty-five minutes, agency call. The agency is doing what was asked. What was asked is no longer the priority after the paid channel decision. Rebrief them, cut one workstream, expand another. Notably: this is a conversation the in-house team had been avoiding for three weeks because they didn't feel senior enough to have it. That's a large part of what the role is for.
Wednesday: deep work
Three uninterrupted hours. No calls. This is the block that most part-time arrangements quietly lose, and losing it is what turns a fractional CMO into an expensive coordinator.
This week it's a positioning problem. The company sells to two segments and has been using one message for both. Sales close rates differ by a factor of three between them, which nobody had connected to messaging. The work is going through call recordings from both segments, pulling the language buyers actually use, and drafting a message hierarchy that splits properly.
Output by the end of the block: a four-page document, a revised homepage headline for the stronger segment, and a rewritten first email in the outbound sequence. It goes to the CEO and the sales lead for comment, with a note that silence won't be read as approval.
Thursday: sales
One hour, sales enablement session. Sitting with two salespeople going through recent lost deals. What objection killed it, what they wished they'd had, what the competitor said that landed. This is the highest-value hour in the week and it's the one most marketing leaders skip.
Findings feed straight back: two battle cards need updating, and one objection is coming up often enough to deserve its own piece of content.
Forty-five minutes, ABM review. The account list is 260 companies. Nine showed buying signals this week: a leadership change, two hiring for roles that imply the problem you solve, a website visit from a named account. Sales gets a brief on each. Prep that used to take a salesperson half an hour per account now takes a few minutes, which is the difference between the program being real and being a spreadsheet.
Friday: write it down
Ninety minutes, the weekly report and the following week's plan. One page. Plain English. What happened, what the numbers did, what was decided, what needs a decision next week, and what's going wrong.
This week's report says the paid channel was killed and explains why, flags that the attribution finding changes how we should read the last two months of reporting, and notes that the case study delay is now a pattern with this customer rather than a one-off.
The report includes the bad news. A weekly report that only contains good news is a document nobody makes decisions from, and it's a fair signal that the person writing it has started managing perception instead of the function.
Where the fifteen hours went
- Leadership and CEO time: about 2 hours
- Team and agency direction: about 3 hours
- Deep work on strategy, positioning, campaigns: about 4 hours
- Numbers, attribution, and reporting: about 3 hours
- Sales enablement and ABM: about 2 hours
- Async, Slack, reviews, the things that don't fit anywhere: about 1 hour
Roughly a third goes to deep work, a third to people, a third to numbers. When an engagement starts failing, the first thing you'll see is deep work getting eaten by meetings. Watch for it.
What this week deliberately didn't include
No design work. No posting on social. No writing the content, only briefing and editing it. No sitting in the ad platform adjusting bids. No sales calls. No hiring interviews, though there's a month where that dominates.
The pattern is that a fractional CMO decides and directs. Every hour spent producing something a specialist could produce is an hour not spent on the thing only they can do, which is the judgment call about where the company should point.
How the week changes over the engagement
Month one looks nothing like this. It's mostly interviews with customers and lost prospects, reading CRM records, listening to call recordings, and auditing tools. Very little visible output, which makes it the month where founders get nervous.
Months two and three are the heaviest. Positioning rolling out, channels being tested, workflows being built. More hours go into building than reviewing.
Months four to six shift toward optimization and documentation. Less new construction, more tuning and writing things down.
Beyond six months the hours should be dropping. If they're not, either the scope grew or the handover isn't happening. Both are worth a direct conversation. How long engagements typically run is covered here.
The part that isn't in the timetable
A good chunk of the value in this role is authority rather than activity. The agency rebrief on Tuesday was overdue by three weeks because nobody internally felt senior enough to make it. The paid channel on Monday would have run another quarter because it looked good in a board pack and killing it required someone willing to say so in front of the CEO.
Those two decisions took under an hour combined. They were worth more than the other fourteen. That's the argument for seniority over hours, and it's the reason the model works at all.
