Most bad agency engagements show their character in the first three sales conversations. The signals are there. Operators miss them because they want to believe and because they have not seen enough agencies to know what normal looks like.

This is the working list. Two columns: walk away, and pay attention but not necessarily disqualifying. Patterns that show up in two or more of the walk-away column at the same time are almost always a hard no.

Walk away

They promise results before they have seen the account

The pitch deck says "our clients see 3x ROAS in 90 days." When you ask whether they would say the same about your account specifically, the answer is yes, before they have looked at a single data point inside your platforms.

A real agency response to a results question is some version of "we cannot tell you a number until we have read your account, but here is the range we typically see for brands at your stage." Agencies that promise specific outcomes before doing diligence are setting a bar they will quietly redefine later.

The average-client results do not match your tier

The case study shows a brand that went from $200k/month to $1.5M/month. You are at $80k/month. When you ask what the agency does with brands your size, the answer pivots to "the same principles apply."

The same principles do not apply. The economics of running ads at $80k a month are different from $200k. The agency that built its operation around $200k+ clients is not going to do its best work for you, and you cannot fix that with effort.

The senior person disappears after contract

You meet the founder in the sales process. The founder is sharp, knowledgeable, attentive. After the contract is signed, every email comes from someone you have never met, and the founder is unreachable.

This is the most common pattern, and it is hard to detect in advance. The defense is question 21 from the 47-question interview script: names of the team, hours per week per person, who covers when someone is out. Get the answers in writing, and verify them at the kickoff.

They will not name former clients

When you ask for references including one ended engagement, they say it is against their policy or that "everyone we have worked with is still a client." Both are lies in different costumes.

Every agency loses clients. The pattern is fine. An agency that pretends otherwise is either hiding that pattern or has not been around long enough to have one.

The contract has no exit clause shorter than 12 months

Standard is 30 days notice. Acceptable is 60 to 90 days. A 12-month minimum with no out is a structure designed to protect the agency from being fired for bad work, which tells you they expect to do bad work or have done bad work before.

Watch for the variant: "you can leave any time, but you forfeit X months of retainer." That is a 12-month minimum with extra steps.

They want full creative control with no operator review

"We need creative freedom to do our best work." Translation: they do not want you to push back on the ads they make. This is bad for brand consistency and worse for performance, because the operator's institutional knowledge about the brand is exactly the input that improves creative.

Healthy creative governance is shared. The agency proposes, the brand has a fast review loop with a default-yes posture, the agency learns the brand voice over time.

They charge for "audits" that are sales pitches

Some agencies offer a "free audit" of your account. Some charge $5k for a comprehensive audit before the engagement begins. Free audits are usually fine. Paid audits that turn out to be 80 percent slides about the agency's methodology and 20 percent actual account observations are a sign of how the engagement will run.

A real audit produces a written document with specific account findings, prioritized recommendations, and a clear scope for what you would do next together. If the audit deliverable is mostly about the agency, you have learned how the agency thinks.

Their reporting structure changes month to month

In month one, the report is a custom Looker dashboard. In month two, it is a Google Slides deck. In month three, it is a Loom video walkthrough. The pattern looks like flexibility. It is actually instability and a sign the agency does not have a settled reporting practice.

Healthy reporting is consistent across months and increasingly readable as the relationship matures.

Pay attention, but not disqualifying

They are slow to respond during the sales process

Sometimes this is a bad sign about how they will run the account. Sometimes it is a sign they are a real working business that gets back to you when they have time, not within an hour of every email. Look for the pattern over four meetings: are they slow but reliable, or slow and unreliable?

Their site has heavy stock photography

Some great agencies have visually weak websites because they spend their effort on client work. Some good agencies just have a website that is overdue for a refresh. Pair the visual signal with the operational signals from your interviews before drawing conclusions.

They specialize in one channel

A pure Meta agency is excellent at Meta and will rarely tell you to spend more on Google. That is a tradeoff worth knowing about, not a disqualifier. Build the channel-mix decision into your in-house process and let the specialist do what they are best at.

They have famous logos in their portfolio

A logo wall of recognizable brands could mean the agency does real work with those brands. It could also mean one strategist worked on a small project for that brand five years ago at a different agency. Ask: which of these clients are current, and which one would you like me to call?

They came highly recommended by a peer

A peer recommendation lowers the bar in your head; do not let it. Some of the most painful agency engagements start with a strong referral. The fit that worked for your peer is not necessarily the fit for you. Run the diligence anyway.

They are smaller or larger than you expected

Smaller than expected can mean lean and senior; it can also mean over-extended. Larger can mean depth; it can also mean layers. The size is not the signal. The size against the brands they serve is the signal. A 40-person agency with 100 clients is over-stretched. A 40-person agency with 25 clients of your tier is operating at a reasonable ratio.

What to do when you see one

One red flag from the walk-away list, with everything else strong, is a real conversation. Bring it up directly in the next meeting. The way they handle the conversation tells you whether the red flag is the visible part of a deeper issue or a fixable misstep.

Two or more from the walk-away column at the same time is a hard no. Find another agency. The cost of finding another agency is less than the cost of an engagement that fails in month four.

The rest of the agency selection process is in the pillar guide, and the working interview script is in the 47 questions. If you are not sure whether you are ready to start the process at all, the readiness diagnostic is the right place to begin.
