What to Ask Before You Hire a Paid Ads Agency

We spent the last few weeks vetting paid media agencies, and the most useful thing we learned did not come from either agency. It came from calling their existing clients and asking a question the sales conversation never surfaces: what do you actually do yourself?

Key Takeaways

• Ask what the client does, not what the agency does — that gap is what you are really buying.
• At small spend, management fees can approach the ad budget — and the math stops working.
• Creative and list-building are the two things that usually fall back on you — and they are most of the work.
• Ask for references at your spend level — not the agency’s flagship account.
• Get the tech-stack answer in writing — who owns the accounts, and does tracking survive if you leave.

The question that changed the evaluation

Both agencies presented well. Both described a full-service engagement. Both were credible.

Then we asked for references and called them. In each case we asked the same thing: what does the agency handle, and what do you end up doing yourself?

Every client gave a version of the same answer. They build their own target lists. They produce their own creative. What the agency does is optimize the campaigns.

That is a legitimate service. It is also a much narrower one than either pitch implied, and it reframes the price entirely. When you understood the fee as covering strategy, creative, audience building, and optimization, it looked reasonable. When you understand it as covering optimization while you still write the ads and build the lists, you are pricing a different thing.

None of this required an adversarial conversation. It required one specific question, asked of people with no incentive to oversell.

Where the math breaks at small spend

The structural problem with agency engagements below a certain budget is simple arithmetic that nobody says out loud.

Agency retainers do not scale down proportionally with spend. Running a campaign takes a certain amount of labor whether the budget is $5,000 a month or $50,000. So the retainer stays roughly flat while your spend shrinks — and at some point the management fee approaches, matches, or exceeds the media budget itself.

At that point you are paying more to manage the money than you are putting into the market, and the campaign has to perform extraordinarily well just to cover the overhead of being managed. That is a difficult bet, and it is one many small advertisers make without ever framing it that way.

The threshold question worth asking yourself before any of the vendor conversations: what percentage of my total paid budget goes to management rather than media? If it is above roughly a third, the engagement needs to be exceptional rather than merely competent to be worth it.

Five questions worth asking

1. Who produces the creative, and what does it cost? “We handle creative” sometimes means an in-house team, sometimes an affiliated agency at an hourly rate, and sometimes you. All three are workable; you just need to know which one before you sign. Ask for the hourly rate if there is one.

2. Who builds the target lists? For anything account-based or audience-driven, list quality determines the outcome more than bid strategy does. If list-building falls to you, that is real internal labor that belongs in the cost comparison.

3. Can I talk to a client at roughly my spend level? This one matters more than it sounds. A reference running ten times your budget gets a different service tier and a different specialist, and their experience will not predict yours. Ask specifically for someone in your range.

4. Who owns the accounts and the data? If you leave, does the ad account come with you? Does tracking survive? Does historical performance data transfer? Get this answered before rather than after, because it is the difference between switching vendors and starting over.

5. Do we keep our existing stack? If your tracking, forms, and attribution work today, find out whether they continue to work or whether the engagement assumes migrating to the agency’s preferred setup. Migration is a hidden project with a real cost.

Meet the person, not the pitch

One more thing worth insisting on: talk to the specialist who would actually run your account, not only the person selling it.

The sales conversation is typically handled by someone senior and persuasive. The day-to-day is typically handled by someone else, often managing a portfolio of accounts. Those are different people with different experience, and the second one determines your results.

Ask how many accounts that person carries. Ask what their reporting cadence looks like in month four, after the onboarding attention has moved on. A vendor with a real answer has thought about retention. One who deflects to “our team” has told you something.

What this means for a home service company

Most home service companies evaluating paid help are in exactly this position: a modest budget, no in-house media expertise, and a pitch that sounds comprehensive.

Three practical takeaways.

Call the references, and ask the narrow question. Not “are you happy” — everyone says yes. Ask what work still lands on them. That single question surfaces the true scope faster than any proposal review.

Count management as part of acquisition cost. When you compute cost per booked job from paid, include the retainer and your own hours. It usually changes how the channel compares against the ones you already have.

Compare against your alternatives, not against zero. The relevant question is not whether paid works — it does. It is whether the same money produces more in a channel with better conversion. Referral leads book at better than 40% across the 300-plus moving companies we work with, and that channel bills you after a job completes rather than before. If your paid engagement is mostly management overhead, the comparison is not close.

None of this argues against hiring an agency. A good one at the right spend level is worth real money. It argues for spending an afternoon on reference calls before you find out what you actually bought.
