I own a marketing agency, and I'm about to tell you how to vet marketing agencies. Yes, including us. Because I'd rather you hire the right agency — even if it's not us — than hire the wrong one and swear off agencies forever.
This industry has a trust problem. Too many businesses have been burned by agencies that promised the moon, delivered a PowerPoint, and charged $5,000 a month for it. I get it. The skepticism is earned.
But a good agency genuinely changes your business. I've seen it hundreds of times. The difference between a good agency and a bad one isn't subtle — it's the difference between growth and a really expensive lesson.
Here's how to tell which one you're talking to.
Step 1: Look at Their Own Marketing
This one's so obvious that people miss it. Does the agency's own website rank on Google? Is their content good? Does their site load fast? Is it mobile-friendly?
If a marketing agency can't market themselves, what exactly are they going to do for you?
Pull up their website on your phone. Run it through a speed test. Google their name plus their city. Check their social media. Read their blog. If any of that is bad — if their site is slow, their content is thin, their social is dead — that tells you everything about the quality of work they'll do for you.
Step 2: Ask for Proof, Not Promises
Every agency has a pitch. "We'll increase your traffic." "We'll generate leads." "We'll grow your business." Okay — show me.
Ask for:
- Case studies with numbers. Not "we helped a client grow" — how much? From what to what? Over what time period?
- References you can actually call. Not testimonials on their website — a phone number for a real client you can have a conversation with.
- Examples of work in your industry or a similar one. If they've never worked with a business like yours, they're learning on your dime.
If they can't produce any of these, they either don't have results worth sharing or they haven't been doing this long enough to have them.
Step 3: Understand What You're Buying
Before you talk to any agency, get clear on what you need:
- Do you need a website built or rebuilt? That's a project with a start and end date.
- Do you need ongoing marketing? That's a retainer for SEO, PPC, content, social, etc.
- Do you need strategy? Sometimes you don't need execution — you need a plan.
Don't let an agency sell you a $3,000/month retainer when what you actually need is a one-time $5,000 website project. And don't expect a one-time project to deliver ongoing results without ongoing effort.
The scope should match the need. If an agency is pushing their biggest package before they understand your situation, that's a sales move, not a strategic recommendation.
Step 4: Ask These Questions
In your first meeting, ask:
"How do you report results?" The answer should include specific metrics — leads, traffic, conversions, revenue where possible. If they say "monthly report" but can't describe what's in it, that's a red flag.
"Who will actually do the work?" Sometimes the senior team pitches you and then hands your account to an intern. Ask who your day-to-day contact is and what their experience level is.
"What do you need from me?" A good agency knows that client involvement matters. If they say "nothing, we handle everything," they're either lying or they're going to make decisions about your business without your input.
"What happens if it doesn't work?" Listen carefully here. A good agency will talk about adjusting strategy, testing different approaches, and transparent communication about what's working. A bad one will dodge the question.
"What do you recommend we NOT do?" This is my favorite. An honest agency will tell you which services you don't need. If they recommend everything on their menu, they're selling — not advising.
Step 5: Start Small
Don't sign a 12-month contract with an agency you've never worked with. I don't care how good their pitch is. Start with a project. A website build. A 3-month ad campaign. A strategy engagement. See how they work, how they communicate, and what they deliver.
If they won't do a smaller engagement first, ask yourself why. If their work is good, you'll want to continue. They shouldn't need a contract to keep you.
The agencies that require long lock-in periods are usually the ones who know clients would leave if they could.
The Final Gut Check
After your meetings, ask yourself:
- Did they ask more questions than they pitched?
- Did they say "I don't know" to anything? (Honesty beats false confidence)
- Did they push back on anything you suggested? (You want a partner, not a yes-machine)
- Can you explain to someone else what they'd actually do for you?
- Do you feel like they understand your business?
The right agency feels like a partner. The wrong one feels like a vendor trying to hit quota.
One More Thing
Be honest about your budget. If you have $1,000/month, say so. A good agency will tell you what's realistic at that level rather than promising everything and underdelivering. A bad agency will take the money and spread it so thin that nothing works.
Marketing isn't free, but it doesn't have to be a mystery. The right investment with the right partner pays for itself. The wrong one is tuition.
