How to Choose a Facebook Ads Agency: Red Flags to Watch For
To choose a Facebook ads agency, check four things before you sign. The ad account should sit in your own business portfolio, and the agency should judge itself on what a new customer costs you. Someone has to make new ads every month, and the structure has to fit your budget. After launch, the ads should change often, the settings rarely, and reports should tie to sales.
Most owners pick an agency from a sales call, and sales calls all sound alike. Everyone promises creative testing and clear reporting. What separates a strong agency from an expensive one shows up later, in what it does to your account on an ordinary Tuesday and what it puts in front of you at the end of the month. So it pays to know what that work should look like before you hear the pitch.
A well-run account has a rhythm. Some things should change every week, and some should be left alone for longer than most owners expect. Agencies that get this backwards can burn through a reasonable budget with little to show for it, because they tinker with settings while the same three ads run for months.
Ads Manager can tell you a lead cost $32. It can't tell you the lead was a student who wanted a job, or a homeowner with a $5,000 budget for a $60,000 project. A good account manager opens your CRM, or asks your front desk, and finds out which leads booked, showed up and paid. That feedback decides which ads get more money, so an agency that never asks about lead quality is steering by the wrong gauge.
Facebook ads wear out as the same people keep seeing them, and new creative is the main lever left once tracking and targeting are set. Meta weighs how likely people are to respond to an ad, alongside your bid, when it decides what to show, so an ad people stop for gets delivered more cheaply than one they scroll past. You should see a steady flow of new versions every month: new openings, new angles on the offer, new formats cut for Reels, Stories and the feed.
Every new ad set goes through what Meta calls the learning phase, and Meta says an ad set usually exits it "after about 50 results in the week after the ad set's last significant edit." The same page tells advertisers to "avoid frequent budget changes" and to "only edit your ads or ad set when you have reason to believe that the edit should improve performance." An agency that rewrites targeting every few days can show you a busy change log, and it keeps your account in a permanent warm-up.
Bad ads are a different matter. A sensible rule of thumb is that a version which has spent two to three times your target cost per booked call without producing a single booking has had its chance. At a $150 target, that's $300 to $450 of spend. Good agencies agree a threshold like this with you up front, so nobody argues later about whether an ad was killed too early.
A monthly report should start with money: what you spent, what came back as booked calls, trials or consults, and what each new customer cost. Reach, clicks and cost per lead belong further down as diagnostics that explain where people dropped off.
Run that rhythm long enough and it adds up. A young golf apparel brand went from four-figure months to its first $105,000 month after we built it an ad system, and in the best month Meta alone drove $92,461 in tracked sales at a 2.8x return. We tested new angles every week, product by product, and when short sleeves and tees pulled ahead at a 3.73x return and about $23 an order, that line got the budget. The golf apparel case study has the full breakdown.
Every agency will tell you it's data-driven. These checks get past that, because each one has an answer you can verify yourself during the sales process.
Yours. The agency should be added as a partner to your business portfolio, which is how Meta designs it. Meta's help page on giving a partner access uses "an agency you work with" as its example, and notes that a partner with full control still can't share the asset onward because "only the organization that owns the asset can share it with another business portfolio." If your ads run inside an account the agency owns, the account history, pixel data and audiences stay with them when you leave.
Listen for cost per customer, or at least cost per booked call, trial or consult, compared with what a customer is worth to you. An answer that stops at cost per lead or ROAS inside Ads Manager is a sign they'll optimize for the cheapest form fills. Cheap leads are the easiest thing to buy on Facebook: loosen the targeting, remove every question from the form, and the cost per lead drops while sales stay flat.
Some agencies produce creative, some expect you to send videos, and many do a mix. Any of those can work. What doesn't work is a vague answer, which usually means the launch ads run until they stop working and then nobody has a replacement ready. Ask for a number of new ads per month and who films or designs them.
Ask how many campaigns and ad sets they'd run, then do the math against Meta's learning phase. Our rule of thumb is to work out roughly how many results each ad set will get in a week: monthly budget, divided by expected cost per result, divided by 4.3 weeks, divided by the number of ad sets. If that lands in single digits, the structure is too big for the budget.
At $4,000 a month and $40 a lead, you get about 100 leads, or roughly 23 a week. In one ad set that's still under Meta's 50, but it's enough signal to learn something. Split across eight ad sets, each gets about three a week and Meta's guidance on avoiding "high ad volumes" starts to bite. The help page puts it plainly: "By combining similar ad sets, you also combine learnings." A proposal with a dozen campaigns on a four-figure budget tells you the agency is building from a template.
The ad's job ends at the form, and your money is still on the line after it. In a Harvard Business Review study of 1.25 million sales leads, firms that tried to reach a lead within an hour were "nearly seven times as likely to qualify the lead" as firms that tried even an hour later. The same authors sent test leads to 2,241 U.S. companies. Among those that replied within 30 days, the average response took 42 hours, and 23% never replied at all.
So a good Facebook ads agency asks how fast your team responds and, ideally, sets up a text and an email that go out the moment a form comes in. An infrared wellness studio did $826,000 in sales over 14 months with ads, funnels and automatic follow-up we built for it, and its typical week grew 177%, from about $6,500 to more than $20,000. Leads who didn't book on the first try kept hearing from the studio until they did. The wellness studio case study shows how each new location opened with members already signed up.
Ask to meet the person who'll be inside your account each week, and ask how many other accounts they handle. A senior strategist on the sales call followed by a junior buyer you never speak to is a common setup, and it's worth knowing before you sign.
The loudest red flag on a sales call is a guaranteed lead count or ROAS before anyone has looked at your account. Nobody controls auction prices or your close rate, so a guarantee is a sales tactic. When it does get met, it's usually met with the cheapest leads Facebook will sell.
Quieter signs matter just as much. Pay attention if the agency plans to run your ads from an account it owns, since that's the hardest thing to unwind later. The same goes for a pitch that spends twenty minutes on targeting and never asks what happens after someone fills out the form, because an agency that never asks about your sales process is planning to be judged on the lead.
If you already have an agency, ten minutes in Ads Manager will tell you most of what you need:
Then ask one plain question, like why cost per booked call went up last month. A specific answer with a change attached is a good sign. A paragraph about "audience saturation" with no plan behind it is a bad one.
A law firm that came to us wrote in its Google review that it "had tried running campaigns with other agencies before and didn't sign a single client." When we dig into accounts like that, the ads are rarely the only problem. Usually the offer asked for too much too soon, or leads waited hours for a reply.
Give it time measured in your own sales cycle. You'll usually see cost per lead and booking rates within a few weeks. Cost per customer takes as long as it takes you to close a sale, which might be a few weeks for a gym membership and a few months for a remodel. Once you're past that point, these four questions settle most cases.
The last box is the one that matters. Compare what a new customer costs in ads with what that customer is worth to you over time. A $600 customer is cheap for a business whose clients spend $5,000 over a year and painful for one selling a $300 package. If the gap is healthy, the right move is usually to spend more, and a good agency will tell you how far it thinks the budget can stretch before cost per customer rises.
When results are poor, Meta's ad relevance diagnostics are a useful second opinion. They rank each ad's quality, engagement rate and conversion rate against ads competing for the same audience, though only for ads with at least 500 impressions. A low quality ranking points at the creative, while a weak conversion ranking points at the page or the offer. Ask your agency what the rankings say and what they're changing because of it.
Start with what's broken. If the account itself is the mess, with a dozen half-dead campaigns and a pixel that double-counts, a good freelancer can often fix it faster and for less than an agency would charge. Running it yourself is reasonable when you have one simple offer and a modest budget, and you're honest that nobody will be checking your work.
It changes when the leads come in and don't turn into customers. That problem usually sits across the ad, the landing page, the tracking and the follow-up at once, and one person rarely has the hours to fix all of it and make new ads every month. An agency earns its fee there, as long as you're actually getting a team for it. We weigh the three setups in more depth in agency vs in-house vs freelancer.
You pay two things: the agency's management fee and the ad budget, which goes to Meta on your own card. Fees are usually a flat monthly amount, a percentage of ad spend, or a percentage with a monthly minimum, and on small budgets the fee can be a large share of the total. Our Meta ads agency cost guide works through each model in dollars and shows how much ad budget Meta needs before it can learn. Facebook and Instagram ads run from the same Ads Manager, so the numbers there apply here too.
Everything above is how we run Facebook and Instagram accounts ourselves. New ads go live every month, cut for Reels, Stories and the feed, and the budget follows the versions that bring in buyers. Every lead lands in a CRM tagged with the ad that brought it in, and it gets a text and an email right away. The number we answer to is what a new customer costs you next to what that customer is worth. Our Meta ads agency page walks through the process step by step.
If you'd like a second opinion on your current account or agency, book a growth audit. It's a 45-minute call with the people who'd run your account, and you'll see what a customer costs you today and what we'd fix first.
Ask whose business portfolio will own the ad account, what number they'll judge themselves on, who makes the ads and how many new ones you'll get each month, how many ad sets they'd run on your budget, and what happens after someone fills out a form. Clear, specific answers to those five questions tell you more than any case study deck.
Guaranteed lead counts or ROAS before they've seen your account, ads running from an account the agency owns, reports that stop at clicks or cost per lead, and the same ads running for months. An agency that never asks about your sales process is another warning sign.
You'll usually see cost per lead and booking rates within a few weeks. Judge cost per customer after one full sales cycle, which could be a few weeks for a gym and a few months for a remodeler. Agree on the numbers and the timing before launch.
In yours. Keep the ad account in your own business portfolio and add the agency as a partner. Meta only lets the organization that owns an asset share it with another business portfolio, so if the agency owns the account, your history and audiences stay with them when you part ways.
Yes. Facebook and Instagram ads are both bought and managed in Meta Ads Manager, so the two names describe the same job. Ask any agency, whatever it calls itself, whether it handles Instagram placements and creative as well.
