How to Choose an AI Marketing Agency: A Buyer's Checklist

Every agency pitch in 2026 has the word AI in it. Some mean a team that built automation into how they run accounts. Some mean one person running prompts into a chat window for four thousand dollars a month. The deck looks identical either way, because the part that differs is not in the deck.

Choosing an AI marketing agency comes down to seven checks: whose name is on the ad accounts, what data you keep on exit, what the pricing rewards, who personally does the work, what gets reported, what the AI concretely does, and what the first 90 days commits them to.

Six of the seven are contract and access questions rather than marketing questions, and none of them appear in a case study.

1. Whose name is on the ad accounts, the pixel and the domains?

Ask this first, because the answer is a fact rather than an opinion and because it is the most expensive thing to get wrong.

An agency can either request access to accounts you own, inside a business portfolio registered to your company, or create accounts inside its own portfolio and run you as a line item. The second is faster for them to set up, and when you leave, the ad account, its spend history and its learning phase stay behind.

The same question applies to four other assets:

• The conversion pixel. If it belongs to their portfolio, your optimization history goes with it.
• Landing page domains. A page on yourbrand.agencysite.com is not yours. Pages on your domain are.
• Tracking phone numbers. Portable only if your name is on the account. Ask what porting out costs.
• Google Business Profile and Search Console. Delegated access, never ownership.

A good answer sounds like: you own everything, we take partner access, here is exactly what we need and why. An agency that resists is telling you something.

Ask for: a screenshot of your own business portfolio showing their agency as a partner, and a walkthrough of the removal process before you sign.

2. What happens to your data when you cancel?

Account ownership is the first half. The data those accounts produced is the second, and usually the real asset.

Then ask the blunt version: if I cancel on Monday, what do I have on Tuesday? Honest agencies answer immediately, because they have done it before. Our client records live in StrideOps, and a client who leaves exports their contacts, conversations and recordings.

The automations are often genuinely the agency's intellectual property, which is reasonable. Your data is not. Keep the two separate in the conversation.

Ask for: an offboarding clause naming what you receive and how long you have to collect it.

3. What shape is the pricing, and what does it reward?

Monthly numbers do not compare across agencies, because each model points the agency at a different outcome. Read the shape before the number.

None of these is dishonest. The problem is only ever a mismatch between what the model rewards and what you hired them for.

Then separate fees from pass-throughs. Ad spend, software licenses, A2P 10DLC carrier fees, call minutes and stock footage are usually billed on top.

Ask for: a twelve-month total cost of ownership, pass-throughs included, divided by the outcome you actually buy.

4. Who does the work, and can you name them?

Agencies sell senior attention and staff junior. That is not always wrong, because a well-run junior on a documented process beats a distracted senior. It is wrong when you were not told.

• Who is on the account, by name and role? Not "a dedicated team." Names.
• In-house, subcontracted or offshore? Any of the three can be good. Not knowing is the problem.
• Who was in the sales call, and will they be in the work? The most common gap in this industry.
• How many accounts does your person handle? Twelve is different from forty.

Then ask what happens when that person leaves, because over two years they probably will.

Ask for: thirty minutes with the person who will run the account, before you sign. If that cannot be arranged, you have learned something.

5. What gets reported, how often, and in what unit?

Most agency reporting is a wall of numbers you cannot act on. Clicks, impressions, reach, engagement rate. None of those are what you sell.

A reasonable setup has three layers: a live dashboard you can open any day without asking, showing spend, leads, booked calls and shows; a weekly five-line note on what came in, what was spent, what changed and what is being tested, which is the cadence that catches a broken form before it costs you a month; and a monthly review call on what worked, what got cut and where the money goes next. Quarterly reporting on a paid media account is not a cadence, it is a hiding place.

The unit matters more than the frequency. Reporting should run to the deepest point in your funnel the agency can see, which for most of our clients is booked calls and shows, because a form fill nobody answers is not a result. If an agency reports only clicks and cost per lead, ask them to add booked appointments and watch whether they can.

Ask for: a sample weekly report and a live dashboard login from a current client, name redacted.

6. What is the AI, specifically?

This is the question the category is built to avoid. Ask it plainly: what does the AI do, where does it run, and what breaks when it is wrong?

Four honest answers are in circulation, and they are very different products:

• AI in creative. Generated images, scripts and variations, tested wider. Real and useful. Ask about disclosure, because the FTC's endorsement guides apply to a synthetic spokesperson the same as a human one, and in August 2024 the FTC finalized a rule banning fake reviews and testimonials. Our AI UGC ads piece covers that line.
• AI in lead response. A voice or SMS agent answering inbound leads. Measurable, because you can time it. How to choose an AI appointment setter is this checklist aimed at that product.
• AI in media buying. Mostly the ad platforms' own automation, which you also have. Fine, but not proprietary, and an agency charging a premium for turning on Advantage+ should say so.
• AI as a search surface. Getting cited inside AI answers rather than ranking under them, which is AEO. Newer, harder to measure, and worth asking how they will show progress.

Then the control questions. Who reviews what the AI produces? What happens when the voice agent cannot answer? Which decisions does a human still make? If the answers are a vendor name and some adjectives, the AI is marketing rather than infrastructure.

Ask for: one thing their AI got wrong on a live account, and what they changed.

7. What does the first 90 days commit them to?

Agency relationships go wrong in month one far more often than month twelve, and a dated launch plan is the cheapest protection available.

• Week-by-week scope for month one. Access granted, tracking verified, first creative live, first report.
• A go-live date per channel, with the dependency named. Most delays are on the client side, which is fine as long as everyone can see it.
• What you owe them. Brand assets, access, a point of contact, approval turnaround.
• Term and exit. Minimum, notice required, whether it auto-renews.
• What happens if launch slips. Does the retainer start on signature or on launch?

We get most clients live in 2 to 3 weeks, and the slow part is almost never the build. It is access, approvals and carrier registration.

Ask for: the actual onboarding document, not a description of it.

Red flags

• Guaranteed rankings. Google's own documentation says it plainly: "No one can guarantee a #1 ranking on Google." Google lists that promise as a warning sign when choosing an SEO.
• Guaranteed lead or appointment volume before anyone has seen your offer, market or close rate.
• Accounts in their name, presented as a convenience.
• No named team. "Our specialists" with nobody you can call means subcontracting they will not admit.
• Clicks and impressions only, with no path to booked calls.
• Percentages with no base numbers. A 400% increase from one lead to five is true and useless.
• Testimonials you cannot verify. Ask for two current clients in your industry and call them.
• Willingness to cold call or cold text purchased lists. It tells you how they treat compliance everywhere else. The FCC confirmed in Declaratory Ruling FCC 24-17 that AI-generated voices count as artificial voices under the Telephone Consumer Protection Act, so AI calls need the same prior express consent as any other artificial or prerecorded call.
• A contract you cannot leave inside twelve months for a reason nobody explains.

None of these proves a bad agency alone. Two together usually does.

A one-page scorecard

Score each agency out of 2 and compare totals rather than monthly fees.

Under 9 out of 14 and you are buying an agency you will be managing.

Should you hire an agency at all?

An agency buys you judgment, reps across other accounts, and someone else being responsible on the Tuesday a campaign breaks. The alternatives are doing it yourself, where the constraint is hours rather than capability, and hiring in-house, which works once your spend makes a salary a small percentage of it. The free AI Operator Kit shows what the build involves before you spend anything, and in-house vs outsourced appointment setting works through the same three-way choice for your follow-up specifically.

The common failure is not picking the wrong path. It is hiring an agency for a job an in-house person should do, or the reverse, then blaming the execution.

FAQ

What is the best AI marketing agency for a small business?

The best AI marketing agency for a small business is the one that puts the ad accounts in your name, hands your data back on exit, prices against booked calls, names the person running your account, and can say exactly what its AI does. No single agency wins on brand.

How much should a small business pay a marketing agency?

Convert every quote to one number: total monthly outlay including pass-throughs, divided by the booked appointments you expect. Percentage of spend, flat retainer, per lead and per appointment produce very different monthly figures for identical work.

What questions should I ask a marketing agency before signing?

Ask whose name is on the ad accounts, what you receive on the day you cancel, what the pricing rewards, who personally runs the account, what the weekly report contains, what the AI does, and what the first 90 days commits them to.

How do I know if an agency's AI is real?

Real AI in an agency has a named job, a named failure mode and a human who reviews its output. Marketing AI has adjectives. A voice or SMS agent is the easiest kind to verify, because you can fill out your own form and time the response.

Should I choose an agency that specializes in my industry?

Industry specialization matters most in regulated work, where mortgage, insurance, lending and medical each constrain what an ad or a call may say. See mortgage AI compliance for how specific that gets.

What is answer engine optimization, and do I need an agency for it?

Answer engine optimization is getting your business cited inside AI answers rather than only ranked in blue links. You do not need an agency for it. You do need content that answers real questions directly and a way to measure progress.
