Every marketing agency sounds good on a sales call. That is the whole point of a sales call. The slide deck is polished, the case studies are impressive, and everyone says some version of the same three or four things. The problem is that a good pitch and a good agency are not the same thing, and the gap between them only becomes obvious a few months in, after the contract is signed and the invoices have started. This is a field guide for spotting the difference earlier. Eight pairs of green flags and red flags, pulled from what we actually see when business owners compare agencies, plus one extra flag that barely anyone is checking for yet: whether the agency has a plan for how AI tools like ChatGPT and Google AI Overviews find and recommend businesses.
Part 01: Strategy Talk
How They Talk About Strategy
The first thing you can evaluate about an agency happens before you have spent a single dollar with them: how they talk. Vague language is not a personality quirk. It is usually a sign that there is nothing specific underneath it.
They speak entirely in buzzwords
"We drive engagement" and "we build brand awareness" sound nice, but they do not tell you what anyone is actually going to do on Tuesday. If an agency cannot walk you through the specific work behind a phrase, the phrase is doing the work the strategy should be doing.
They answer in plain English
A good agency can tell you, in one or two sentences, exactly what they will do and why. "We will run Google Ads targeting people searching for your service right now, and we will build out city pages so you rank locally without paying for every click." That is a plan. You can picture it.
One strategy, every client
If the pitch feels like it would work word for word for a dentist, a roofer, and a law firm, it probably has been used for all three. A strategy that never changes shape is not a strategy. It is a template with your logo on it.
They ask about your business before they pitch anything
How you get paid, what your busy season looks like, what a good customer is actually worth to you: these are the questions that shape a real plan. An agency that asks them before recommending anything is building the strategy around you instead of fitting you into one.
Part 02: Money and Results
How They Handle Money and Results
This is where the sales call meets reality. How an agency talks about numbers and contracts tells you how confident they actually are in what they deliver.
They will not show you real numbers
Stock photos and vague "results" with no methodology behind them are not proof of anything. Client privacy is a legitimate reason to keep a name off a case study. Having nothing specific to show you at all is a different problem entirely.
They lead with actual client results
Real numbers, a clear before and after, and a willingness to explain what worked and what did not, whether the client is named or described in detail. An agency that is proud of its work shows it without being asked twice.
They lock you into a long contract right away
A twelve month commitment before you have seen a single result is a bet you are being asked to place on their behalf. Long contracts are not automatically bad, but a long contract with no early proof point is a warning sign worth taking seriously.
They are confident enough to earn your business monthly
An agency that structures its work so you can leave without a fight is telling you something important: they expect you to want to stay because the work is good, not because you are contractually stuck.
The best test of an agency is not what they promise on the call. It is what they are willing to show you before you have signed anything.
Part 03: Life After the Contract
How They Treat You After You Sign
The sales process is designed to be a good experience. What happens after the contract is signed is where you find out what the agency actually is.
You cannot reach a real person
If your point of contact keeps changing, or emails take a week to get a reply, that is your working relationship for as long as you stay. It does not improve on its own.
You know exactly who to call
A named point of contact who knows your account without needing a recap every time. Small thing to look for, huge difference to live with.
Reporting is a black box
A monthly PDF full of charts that never quite explain whether the phone is ringing more is not reporting. It is decoration. If you cannot tell what is working, neither can they.
You can see what is working and what is not
Clear reporting tied to the numbers that actually matter to your business, like calls, form fills, and booked jobs, not just clicks and impressions. If something is underperforming, they say so and tell you what changes next.
Part 04: Where Search Is Headed
How They Think About Where Search Is Headed
This last pair is newer than the rest, and it is quickly becoming one of the clearest ways to tell an agency that is paying attention from one that is still fighting last decade's battle.
They cannot speak your industry's language
If they call your customers "verticals" and cannot tell the difference between a service call and a sales lead, they are managing your account the same way they manage everyone else's. Your industry has specific words, specific problems, and specific buying triggers. An agency that has not bothered to learn them has not bothered to learn your business.
They already talk like someone in your industry
They know the difference between a repair call and a replacement job, or a switch customer versus a first-time buyer, because they have worked with businesses like yours before and it shows in how they talk about the work.
No plan for how AI tools find businesses
ChatGPT, Perplexity, and Google AI Overviews are already answering "who should I call" questions for real customers, in your market, right now. An agency with no point of view on this is optimizing for a version of search that is quietly shrinking.
They are actively building for AI visibility
They can explain, specifically, how the content they build helps AI platforms understand and recommend your business, not just how it helps you rank on a results page. That is a sign they are building for where search is going, not just where it has been.

Part 05: The Shortcut
The One Question That Cuts Through All of It
Reading eight flag pairs before a discovery call is a lot to hold in your head. If you only have time for one question, make it this one.
"Can you show me a real result for a business like mine, and tell me exactly what you would do differently for me?" An agency with a real answer will light up. An agency without one will reach for a buzzword.
Notice how they answer, not just what they answer. Do they get specific fast, or do they circle back to the same three phrases from the pitch deck? That reaction tells you more than the rest of the sales call combined.
Key Takeaways
- Vague language on a sales call is usually a sign that there is nothing specific underneath it. Plain English answers are a green flag worth paying attention to.
- An agency that asks about your business before pitching anything is building a plan around you instead of fitting you into a template.
- Real, named results beat blurred-out screenshots every time. If an agency cannot point to specific proof, that is worth noticing.
- Long contracts with no early proof point put the risk entirely on you. Confident agencies earn your business month to month.
- A named point of contact and reporting tied to real business outcomes, like calls and booked jobs, are the difference between a partner and a vendor.
- Agencies that already speak your industry's language have usually done the work of understanding your business, not just your budget.
- How an agency thinks about AI search visibility is quickly becoming one of the clearest signals of whether they are building for where search is going.
- One question can cut through most of the noise: ask for a real result for a business like yours and watch how specifically they answer.
Frequently Asked Questions
What is the biggest red flag when hiring a marketing agency?
Vague language without specifics is the most common and most telling red flag. If an agency describes its work in phrases like "driving engagement" or "building your brand" and cannot explain the actual tactics behind those words, there is usually no concrete plan underneath the pitch.
How can I tell if an agency's results claims are real?
Ask for an example in a similar industry with specific numbers tied to the work, such as call volume, booked jobs, or ranking positions. It is normal and often necessary for an agency to keep a client's name out of a public case study for privacy reasons. What matters is whether they can walk you through real detail behind the results. If they hedge, generalize, or cannot get specific even in a private conversation, that is the actual warning sign.
Should a marketing agency lock me into a long-term contract?
A long-term contract is not automatically a problem, but one offered before you have seen any early results shifts the risk onto you. Agencies confident in their work often use shorter initial terms or month-to-month structures because they expect the results to be the reason you stay, not the paperwork.
What questions should I ask an agency about AI search visibility?
Ask them directly how their strategy accounts for tools like ChatGPT, Perplexity, and Google AI Overviews, which are increasingly answering "who should I call" questions for customers before a traditional search ever happens. An agency with a real answer can describe specific content and structural decisions built for AI visibility, not just traditional page one rankings.
What if an agency checks some of the green flags but not all of them?
Few agencies will be perfect across every category, and that is normal. Pay closest attention to the money and reporting flags, since those affect you every month you work together, and treat vague strategy language as the flag most worth pushing back on before you sign anything.
Is a full-service agency automatically a green flag over a specialist?
Not automatically. Size and service range matter less than whether the agency actually understands your industry and can show specific results in it. A smaller specialist with real proof in your space can be a better fit than a larger agency with none.
