A good marketing consultant leaves you with fewer, better decisions. A bad one leaves you with a deck.
A marketing consultant advises on a defined problem, such as positioning, a launch or a channel plan, for a set period. An agency executes. A fractional CMO owns the results over months. Hire a consultant when you need an outside view and have people to carry it out.
Why companies are buying advice now
Budgets are tight and the tools are changing. Gartner's 2026 CMO Spend Survey of 401 marketing leaders found budgets at 7.8 percent of company revenue. CMOs put an average 15.3 percent of that into AI, yet only 30 percent say their AI capabilities are mature.1 Many teams have the tools and lack a plan for them.
Consultant, fractional CMO or agency?
| Consultant | Fractional CMO | Agency | |
|---|---|---|---|
| Job | Advice on a defined problem | Owns marketing direction and results | Executes campaigns and assets |
| Time | Weeks | Months, a few days each | Ongoing |
| Leaves you with | A decision and a plan | A working team and a rhythm | Output |
| Best when | You have doers and need direction | You need a leader and can't hire one yet | You know what to do and need hands |
What good consulting looks like
- A sharp question. "Why are trials not converting?" beats "help with marketing".
- Evidence first. Interviews, data and an audit before opinions.
- A short written plan. Three priorities, owners and dates. Long decks rarely get used.
- A handover. Your team should be able to run it without the consultant.
- A check-in. One review a month or two later to see what changed.
Advice is cheap. Advice your team can act on Monday morning is worth paying for.
How to choose
- Ask for one problem they solved that looks like yours, with a number.
- Ask what they'd need from you in the first two weeks.
- Agree the deliverable and the date before you agree the price.
- Check they can work with your website, data and AI tools, not only slides.
Questions people ask
What does marketing consulting cost?
Most consultants price by project or day. Fixed project prices make budgeting easier. Mine are a fixed project price, agreed before we start.
Can a consultant also build things?
Some can. I design and build websites and context systems as well as advise, so the plan doesn't stall at handover.
When should we hire a fractional CMO instead?
When you need someone accountable for results over months, not a plan alone. Read what a fractional CMO is.
