How a paid ads agency actually works

What a paid ads agency really does, how it charges, what stays your responsibility, and the questions that separate a serious operation from a pitch.

Also available in: Português · Español

Hiring a paid ads agency is usually decided on the pitch rather than the process, which explains most relationships that end badly in three months. Worth understanding what the operation actually is before comparing proposals.

What the agency does, week to week

Stripping the marketing out of the description, the work is this:

Structure. Defining campaigns, ad sets, audiences and budgets. Happens at the start and gets revisited when something changes.

Creative. Producing or coordinating the production of pieces. The main lever on Meta and TikTok, and what most distinguishes one agency from another.

Optimization. Reading what is happening and adjusting. In practice: cutting what does not convert, raising where demand exists, swapping tired pieces.

Measurement. Making sure the pixel fires, the conversion is the right one, and the source arrives tagged in your CRM.

Reporting. Translating what happened into a decision, not into a table.

The fourth line is what is most often missing in a bad agency, and it is what makes all the others work. The standard is in UTM parameters for ads.

How they charge

Three models, with different effects:

ModelHow it worksThe incentive it creates
Flat feeMonthly amount regardless of budgetNeutral, the most common
Percentage of spendA percentage of what is investedIncrease the budget
Fee plus variableBase plus a bonus on a targetAligned, if the target is right

The second model deserves attention: it rewards spending more, not spending better. Not dishonest in itself, and worth knowing the incentive exists before signing.

In the third, everything depends on which target triggers the variable. A bonus on lead volume rewards cheap leads; one on confirmed sales rewards what you want. Market ranges are in how much to charge for ads management.

What stays yours

This is the part that generates the most conflict, because it is rarely said at the start.

The product and the price. No campaign fixes an offer the market does not want.

The site and the landing page. Where half the conversion is won or lost, and usually outside the agency's scope.

Sales follow-up. A lead waiting two days for a call becomes a "bad lead" in the report.

The budget decision. The agency recommends; you decide how much to invest.

When one of those four is the bottleneck, switching agencies does not fix it — and that is what happens in most switches.

The honest timelines

First two weeks. Setup, measurement and first pieces live. Results here are noise.

Thirty days. You can tell whether the direction is right: events arriving, cost per result in a plausible range, creative with traction.

Ninety days. You can judge. There has been time to test, cut and repeat, and the sales cycle has closed at least once.

A long sales cycle pushes everything. If your customer takes 45 days to decide, judging the agency on 30 days of data is judging before the result exists.

Who owns the ad account

It should be you, in your business portfolio, with the agency holding access. It sounds administrative and it is the item that costs the most in a separation.

If the account sits in the agency's portfolio, ending the relationship costs you the optimization history, the custom audiences and, depending on how the pixel was created, the site's conversion history. Starting over costs weeks of performance.

The clauses that prevent the argument at the end are in paid ads management contract.

The questions that separate a serious operation from a pitch

Five short questions, and what the answer reveals:

  1. "How do you measure sales, not platform conversions?" Anyone without an answer will report platform numbers as if they were revenue.
  2. "How many new creatives per month?" A vague answer means the account declines in month two.
  3. "Which portfolio does the ad account sit in?" The right answer is yours.
  4. "What do you do when results get worse?" A process, not an adjective.
  5. "Who talks to me day to day?" Finding out whether whoever sold is whoever operates.

Question 1 is the most revealing. An agency reporting only the platform panel is not measuring your business, it is reading someone else's report.

The warning signs

A guaranteed number. Nobody controls enough variables to guarantee sales.

Budget mixed into the fee. A lack of transparency in the most basic arithmetic of the relationship.

A report with no sales by source. A table of impressions and clicks is not a results report.

No questions about your business in the sales meeting. Anyone who does not ask about margin, ticket and cycle will not set a target that makes sense.

A long contract with no exit clause. Twelve months with no way out is asymmetric risk.

Agency, freelancer or in-house

The choice before the choice, and each option fails for a different reason.

Freelancer. Cheaper and closer. Works well for a single channel on a small budget. Fails on continuity: a holiday, an illness or a bigger client leaves your account idle.

Agency. More expensive and with process. Wins on coverage and on having seen your problem in another client. Fails when you are the small account in the portfolio.

In-house. The most expensive of all and the only one that accumulates knowledge of your business. Fails in a small operation, where there is not enough work to justify a dedicated person.

The practical criterion is the monthly media budget. And worth saying what none of the three fixes: a product with no demand, a page that does not convert, and a sales team that does not call back.

What a good report contains

It is not a platform table. It is:

  • Spend for the period, against the previous one.
  • Results and cost per result, per campaign.
  • Sales by source, with data from your sales team.
  • What changed in the account, one sentence per item.
  • What will be done next period.

The last two lines are what separate a report from an export. The model is in client reporting for small agencies.

Before signing

Ask for the report template you will receive, filled with another client's anonymized data. It says more about the operation than any deck, because it shows what the agency considers a result.

And confirm the three structural items: account in your portfolio, budget separate from the fee, and an exit clause with a term. Everything else adjusts; those three do not. The document the agency promises to deliver is on the paid media reporting page.

Frequently asked questions

Is ad spend included in the agency fee?

Almost never, and it is the first thing to clarify. The fee pays for management; the budget goes straight to the platform. A proposal that does not separate the two is the first warning sign.

How long until it works?

Thirty days to know whether the direction is right, ninety to judge. A campaign needs to accumulate conversions to stabilize, and a long sales cycle pushes the timeline further.

Who owns the ad account?

It should be you, with the agency holding access. An account in the agency's portfolio means the history and the pixel do not come with you if the relationship ends.

Does an agency guarantee results?

No serious one guarantees sales, because half the variables are yours: price, product, site, follow-up. What gets guaranteed is process — what will be done, how often, and what will be reported.
