21 Essential Questions to Ask a Marketing Agency Before Signing

Choosing the wrong marketing agency can cost you 6-12 months of growth and hundreds of thousands in wasted ad spend. Yet most DTC founders go into agency interviews unprepared, asking surface-level questions that reveal nothing about the agency's actual capabilities.

After working with 200+ DTC brands and seeing countless agency transitions, here are the 21 questions that separate world-class agencies from expensive disappointments.

Strategy & Approach Questions

1. "Walk me through your first 90 days with a new client in our industry."

The best agencies have documented playbooks. They should outline specific audits, testing frameworks, and milestone goals. Red flag: vague answers about "getting to know your brand."

2. "What's your philosophy on creative testing?"

Top agencies test 8-12 new creative concepts weekly. They should explain their testing methodology, statistical significance thresholds, and refresh cadence. Bonus points if they mention angle diversification.

3. "How do you approach incrementality testing?"

Most agencies can't answer this. Elite agencies run geo-holdout tests, brand lift studies, and conversion lift tests. They understand the difference between correlation and causation in attribution.

4. "What's your take on iOS 14.5's impact on attribution?"

Strong agencies adapted quickly, implementing Conversions API, server-side tracking, and diversified attribution models. They should discuss platform-native attribution, incrementality testing, and MMM (Media Mix Modeling).

Team & Expertise Questions

5. "Who will actually work on my account day-to-day?"

Meet your actual team, not just the sales team. At ATTN, clients work directly with our specialists: Hugo (Meta), Stephen (Google), Dennis (TikTok), Miranda (Email/SMS), and Becca (Onboarding).

6. "What's your team's experience in our industry/AOV range?"

Industry matters. Coffee subscription strategies don't work for supplement brands. Pet brands have different creative angles than beauty. Look for 10+ similar clients, not just 1-2 case studies.

7. "How do you handle team turnover?"

Good agencies have documented processes that survive personnel changes. They should explain knowledge transfer protocols and account continuity plans.

Performance & Reporting Questions

8. "What metrics do you optimize for?"

Beyond ROAS, they should discuss CAC payback, LTV:CAC ratio, contribution margin, and blended performance. Red flag: agencies that only care about platform metrics.

9. "How do you report incrementality vs. attribution?"

Elite agencies separate attributed revenue from incremental lift. They should explain how they measure true incrementality, not just last-click attribution.

10. "Can you show me a real client dashboard?"

Insist on seeing actual reporting (anonymized). Look for:

Multiple attribution windows
Cohort analysis
Creative performance breakdowns
Budget allocation recommendations
Incrementality insights

11. "What's your average client ROAS improvement in the first 6 months?"

Specific numbers matter. Strong agencies see 15-30% ROAS improvements within 6 months. But ask about the distribution - are improvements consistent or just outliers?

Process & Communication Questions

12. "How often do we communicate, and in what format?"

Weekly calls are standard. Monthly is too infrequent. Daily is overkill unless you're scaling rapidly. Look for structured reporting, not just "check-ins."

13. "What's your creative production process?"

They should explain brief development, creator management, feedback loops, and asset delivery timelines. How many concepts do they test monthly?

14. "How do you handle budget allocation across channels?"

Strong agencies use data-driven allocation based on incrementality, not vanity metrics. They should explain rebalancing triggers and channel priority frameworks.

Financial & Legal Questions

15. "What are your payment terms and fee structure?"

Typical structures:

Management fee: 10-15% of ad spend
Flat retainer: $5K-$15K/month
Performance bonuses: tied to incrementality

Understand what's included. Creative production is often extra ($2K-$8K monthly).

16. "What's your minimum contract length?"

3-6 months is reasonable. 12+ months is a red flag unless you're getting significant rate discounts. Month-to-month means no commitment to your growth.

17. "How do you handle contract termination?"

Understand asset ownership, account access transfer, and knowledge handoff procedures. You should own all creative assets and audience data.

Strategic Vision Questions

18. "Where do you see our industry heading in the next 2 years?"

Strong agencies think strategically about privacy changes, platform evolution, and channel diversification. They should have opinions on emerging channels and regulatory impacts.

19. "What channels beyond Meta and Google do you recommend?"

Single-channel agencies are risky. Look for expertise in TikTok, Pinterest, CTV, email/SMS, and retail media. Diversification reduces platform dependency.

20. "How do you approach retail media if we're expanding to wholesale?"

Retail media is exploding. Amazon DSP, Target Roundel, Walmart Connect, Instacart Ads. Strong agencies understand the retail media ecosystem.

21. "What would make you fire us as a client?"

This reveals their expectations. Good answers: lack of creative resources, unrealistic ROAS expectations, poor communication, insufficient budget for testing.

Red Flags to Watch For

Guarantee specific ROAS numbers: Performance depends on product-market fit, creative quality, and market conditions. Nobody can guarantee specific returns.

Unwillingness to share case studies: Strong agencies have plenty of success stories (with client permission).

Focus only on vanity metrics: CTR, CPM, and reach don't matter if they don't drive profitable growth.

No industry experience: Every vertical has nuances. Generic approaches rarely work.

Vague testing methodologies: "We'll test some things and see what works" isn't a strategy.

Poor communication during the sales process: If they're hard to reach during courtship, imagine after you sign.

What Elite Agencies Do Differently

The best agencies think like growth partners, not service providers. They:

Proactively suggest budget increases when incrementality is proven
Build custom attribution models for your business
Maintain creative testing velocity of 8+ concepts weekly
Diversify channels based on incrementality, not ease of management
Understand your unit economics better than you do
Challenge your assumptions about customer segments and lifetime value

Making Your Decision

Don't choose based on chemistry alone. Personality fit matters, but performance pays the bills. Look for:

Documented processes: Playbooks, testing frameworks, reporting standards
Industry expertise: 10+ similar clients with verifiable results
Team depth: Specialists, not generalists managing everything
Attribution sophistication: Understanding beyond last-click attribution
Strategic thinking: Long-term vision, not just campaign execution

The ATTN Approach

When prospects ask us these questions, we're thrilled. It shows they understand performance marketing beyond surface metrics.

We share our 90-day playbook, introduce them to their actual team members, and show real client performance data (anonymized). We explain our 4-channel approach: paid social (Meta, TikTok), search (Google, Bing), CTV (Samsung, Roku), and retention (email/SMS).

Most importantly, we audit their current performance before making promises. Every brand is different, and honest agencies acknowledge that.

The right agency becomes your growth accelerator. The wrong one becomes an expensive education. Ask the right questions upfront to avoid painful lessons later.

Remember: agencies work for you, not the other way around. If they can't answer these questions clearly and confidently, keep looking.
