Every online marketing agency pitch includes the word "expert." Almost none of them explain how you're supposed to verify that before you've paid them for six months. Here's the actual test, and what it usually reveals.

The Three Questions That Cut Through the Pitch

Ask for a client at a similar revenue stage to yours, the specific problem that client walked in with, and the measurable outcome — not "increased visibility," a number. Ask what they'd do differently on that engagement if they could redo it; real operators can answer this immediately, marketing theorists can't. And ask who on their team actually worked the account day to day, since the person in the sales pitch is rarely the person doing the work.

The Deeper Problem: Who Judges the Answer?

Even a good agency's answers only help if someone on your side can evaluate whether they're actually good answers. That's the part most owners skip past. If nobody in your business has run marketing at the leadership level before, you're not really vetting expertise — you're trusting a sales process to grade its own homework.

That's the specific gap I fill as a fractional CMO and AI marketing consultant: 28 years of having actually run marketing inside twelve companies, so when a vendor's proposal is genuinely strong, I can tell, and when it's polish over substance, I can tell that too. You get a second opinion from someone with nothing to sell you except the truth.

What "Expert" Should Actually Mean

Real expertise sounds like specifics: "here's what we changed in the account structure and here's the CPA before and after," not "our proprietary methodology." If a pitch stays vague under direct questions about a comparable client, that's your answer regardless of how polished the deck was.

If you want the vetting done for you, and someone accountable for whatever you hire afterward, that's exactly the role a fractional CMO plays — not a replacement for good execution partners, but the judgment that tells you which ones are actually good before you find out the expensive way.

  • Test any agency's "expert" claim by asking for a specific comparable client, the actual problem, and a measurable outcome — not vague language.
  • Vetting an agency's expertise requires someone on your side who can judge marketing expertise, which most businesses don't have in-house.
  • A fractional CMO provides that judgment as part of the engagement, evaluating vendors with nothing to sell except an honest opinion.
