How to Evaluate a GTM Agency: Eight Questions That Reveal the Truth

The agency pitch is designed to produce confidence. The questions that reveal the real agency are the ones they are not prepared for. This piece provides eight specific questions — on accountability, attribution, and underperformance — and explains what the quality of each answer tells you about whether the engagement will produce commercial results.

The agency pitch is designed to produce confidence. Slide decks are polished. Case studies are selected for maximum impact. The team presented is often not the team that will work on your account. The questions asked in a standard agency evaluation — how many clients do you have, what industries have you worked in, what results have you produced — are all answerable in ways that make every agency look capable, regardless of whether they are.

The questions that reveal the real agency are the ones they are not prepared for. They are questions about how decisions are made, how problems are handled when results do not materialise, and how senior the actual working team will be.

Eight questions that reveal the real agency

Who is going to be in our weekly meetings? The managing partner who presented may not be the person running the account. Understanding whether the senior talent presenting is operationally involved or purely a front for a junior team is the most important question in any agency evaluation. Ask it directly. Ask for the name and experience level of the specific person who will lead the engagement.

How do you attribute results to pipeline, not activity? Most agencies measure the activities they control: impressions, clicks, MQLs generated, content pieces published. The agencies worth working with measure pipeline influenced and customer acquisition cost. If the answer to this question centres on activity metrics, the commercial incentive structure of the engagement will produce more activity, not more revenue.

Show me a campaign that did not work and what you did about it. The answer reveals how the agency handles underperformance. Agencies that have never run a campaign that did not work have not run many campaigns. The quality of the retrospective — how quickly the problem was identified, what the diagnosis was, what was changed and why — tells you more about operational competence than any case study.

How will you get up to speed on our market? The assumption that industry experience is equivalent to market knowledge in your specific context is almost always wrong. The agency that served a competitor in your vertical understands that competitor’s positioning and buyer, not yours. The answer should describe a structured onboarding process that includes primary research into your specific ICP and competitive context.

What happens if we are unhappy in month three? Contract structures and the agency’s response to dissatisfaction tell you a great deal about confidence in their own performance. An agency that offers a clear, low-friction exit process is confident their work will earn continued investment. An agency that requires long contract commitments with penalty clauses is not.

What will you not do? Agencies that offer every service to every client are optimising for contract value, not for your outcomes. The agency that tells you what falls outside their competence and recommends you source it elsewhere is demonstrating the confidence and commercial integrity you want in a partner.

How do you handle the period when results are slower than projected? The pipeline impact of a well-designed GTM programme typically lags the activity by three to six months. Agencies that set accurate expectations about this timeline are easier to work with than those who project results that materialise faster than the commercial reality supports. Ask what the agency expects from the first 90 days and whether that matches what you expect.

What is your pricing model, and how does it align with our outcomes? Agencies paid on time spent are incentivised to spend more time. Agencies paid on retainer are incentivised to maintain the relationship. Agencies with any component of performance-based compensation are incentivised to produce the specific outcome the performance metric measures — which is either a strength or a risk depending on how that metric is defined.

What a good answer looks like

The agency worth working with answers these questions with specificity. They name the person who will run the account. They describe the attribution model they use. They share a specific example of underperformance and what they did about it. They are comfortable acknowledging the limitations of their model and the timeline for results. They do not over-promise. The agency that answers every question with confidence and no qualifications is the one to be most cautious about.
