Finding an agency that sounds smart is easy. Pitch decks are slick, logos are impressive, and sales reps know all the right terms.
The real challenge for a Marketing Director or CEO at a mid-market B2B or CPG company comes down to cutting through the show. You need to know if an agency can actually deliver when your revenue and brand equity are on the line.
If you are currently shopping for an agency partner, here is what good actually looks like, which red flags should end the pitch call immediately, and the exact questions to call BS on bad proposals.
1. Scope & Strategy: Real Outcomes vs. Deliverable Treadmills
What to Look For
A real partner talks about business growth, not monthly output quotas. Before suggesting a single tactic, they should interrogate your sales cycle, customer acquisition costs (CAC), lifetime value (LTV), and distribution model.
What a Good Answer Sounds Like
"We are not going to sign you up for 12 blog posts and 20 social graphics a month just to keep ourselves busy. First, let us audit where your pipeline is leaking and fix the conversion path. We tie our work to revenue generated, not assets shipped."
🚩 Red Flag: Selling You Output Volume as a Flex
Run away from agencies whose main value proposition is a massive checklist of deliverables ("We deliver 15 blogs, 30 posts, and 4 newsletters every single month!"). Deliverable volume is a crutch used by agencies that do not know how to drive business impact. When you pay for output volume, you pay for noise.
2. Proposals & Pitches: Tailored Strategy vs. Recycled Decks
What to Look For
A proposal should prove the agency actually did their homework on your specific positioning, audience, and market realities. Look for a clear observation of your current strategic gaps, not generic advice cut and pasted from their last pitch.
What a Good Answer Sounds Like
"We audited your primary competitors and found a glaring hole in how your value prop is communicated on key landing pages. Here is the exact positioning shift we would test in Month 1 to capture high-intent buyers."
🚩 Red Flag: Cookie-Cutter Proposals and Templated Audits
If the pitch deck is loaded with generic filler, relies on universal frameworks that could apply to a dog food brand or an enterprise SaaS platform, or accidentally leaves another client's name in the footer, walk away. Templated pitches mean templated execution.
3. Account Teams: Dedicated Experts vs. The Pitch-and-Switch
What to Look For
Total transparency on who actually does the work. The people pitching you on day one should be the strategists and builders running your campaigns on day 100, not junior coordinators hiding behind an account executive.
What a Good Answer Sounds Like
"The lead strategist and performance marketer on this call are your direct points of contact. We cap our client-to-strategist ratio at 4:1 so nobody gets burnt out, and our core team has been together for over three years."
🚩 Red Flag: Revolving-Door Account Teams
Agencies built on churn-and-burn staffing swap out account managers every six months. When team turnover is high, your strategy gets trapped in endless reset cycles, lost context, and constant onboarding delays.
4. Reporting: Transparent Growth vs. Vanity Metric Shields
What to Look For
Reporting that ties back to your P&L statement. A competent team focuses on qualified pipeline, opportunity creation, CPG retail sell-through, and net CPA adjustments.
What a Good Answer Sounds Like
"Impressions and clicks tell us if creative is landing, but our executive reviews focus strictly on one thing: how much qualified pipeline and revenue we helped generate this month."
🚩 Red Flag: Hiding Behind "Brand Awareness"
When campaigns stall, predatory agencies hide behind fluff metrics like total reach, pageviews, and impression counts without ever connecting them to sales or pipeline growth.

Ask This Question | What You Want to Hear | What Should End the Call |
|---|---|---|
"Who specifically is working on my account every day?" | Direct intros to senior/mid-level specialists who will execute the work. | Vague promises that an "expert team" will be assigned after you sign. |
"Tell us about a time a campaign flopped. What happened?" | Honest stories, fast pivots, and clear risk management. | Defensive claims that their framework "never fails." |
"How do you tie your deliverables back to our bottom line?" | Clear reporting models integrated with CRM data, attribution setups, and revenue KPIs. | Hiding behind social engagement rates, impression totals, or output counts. |
"What do you need from our team to actually make this work?" | Demands for access to sales reps, customer feedback, CRM data, and direct access to decision-makers. | "Nothing. We handle everything in a silo." |
