5 Signs It's Time to Fire Your Ad Agency
February 12, 2026
Short answer: The best Meta ads agency for a supplement brand usually is not an agency at all. It's one experienced person who reads your label before your ad account, can rewrite your ads inside Meta's health rules on the spot and runs few enough accounts to watch yours every day. Test for those three things before you sign.
Before any of that, here's who shouldn't hire anyone yet. If the honest reason people buy your product is that it treats a condition, no agency can fix that on Meta. You cannot say it in an ad and the FDA says a supplement can't claim it anywhere. You need a different pitch first, not a different partner.
The same goes for a brand that hasn't sold to strangers yet. If every order so far came from friends, family and your own audience, nobody knows what a first order is worth or what you can pay for one. A good operator will tell you that on the first call. A bad one will take the retainer anyway.
If you've already been through an agency that didn't work, this is for you. I'll walk through what to look for, how to test someone on your own ads, the pitch answers that should end the call and what the first 90 days should look like in 2026.
The best fit is someone who has run supplement accounts before, writes or directs the creative themselves and isn't spread across a dozen other businesses. Supplement accounts reward focus more than most. The policy rules change what you can say, the tracking can be restricted without warning and the winning ad from last month stops working fast.
Attention is the part most founders never ask about. The UM Per-Marketer Account Load Standard puts each Unicorn Marketer on 3 to 5 client accounts at a time, while a typical agency media buyer is managing 10+. That is not a knock on anyone's talent. It is how many hours are left for your account once everyone else's fires are put out.
A traditional agency can run a supplement account well when the person actually doing the work is senior and has the time. The problem is that you usually meet that person in the pitch and never again. So before you pick anyone, ask who will be in your account on a Tuesday afternoon and how many other brands they're in that same week.
If you want the longer version of that math, I wrote about how many accounts one media buyer can manage well.
It needs someone who reads your label before your ad account. Every claim on the Supplement Facts panel and the front of the tub sets the limit for what the ads can say. Most agencies start with your ROAS. The right person starts with your bottle.
That order matters because Meta's rules sit on top of the law here. Meta's Personal Attributes policy says ads can't assert or imply things about the viewer, physical and mental health included. Its Health and Wellness standards add age targeting rules for dietary and weight loss products and ban claims about curing listed diseases. Then the FDA's page on structure/function claims draws the legal line between supporting a function and treating a disease.Someone new to supplements learns those rules by getting ads turned down on your account. That costs you weeks and can flag your ad account.
The second gap is creators. Most supplement accounts lean on customer and creator videos, and the FTC expects anyone who was paid or sent free product to disclose that connection (FTC, Endorsement Guides FAQ). Ask how they handle disclosure on whitelisted creator ads. The right person has an answer ready. Most people haven't thought about it.
The third gap is tracking. Meta can place a health-related site in a restricted data category and limit the purchase events your campaigns optimize on (Meta Business Help, About data source categories). I covered how to check yours in how to run Meta ads for a supplement brand. For hiring, the point is simpler. Whoever you're talking to should bring it up before you do.
Run the rewrite test. Send them your three best-performing ads and one you know got rejected, then ask two questions on the call. Which line in each ad would Meta or the FTC have a problem with? What would you change to sell the same outcome without it?
You'll learn more in that 20 minutes than in a 40-slide deck. The right person will point at the exact sentence that asks the viewer about their body or promises a result your label can't back up. Then they'll rewrite it while you watch. The wrong one will talk about hooks and thumb-stop rates and never touch the claim.
Watch how they treat the turned-down ad too. Good operators get curious about why Meta said no and whether the account has a pattern. Weak ones blame Meta's reviewers and move on.
If they will not do it without a signed contract, that tells you something as well. Plenty of good people protect their time. But someone who wants your money should be able to look at four ads for free.
For more questions to bring to that call, questions to ask before hiring an ad agency has a full list.
Four answers should make you thank them and hang up.
None of these need you to be an expert. They just need you to ask.
They should show you supplement results with the brand, the numbers and the channels named. Anything vaguer than that is a story.
Here's what I mean, using the supplement brands our Unicorn Marketers have worked with. Onnit's program ran on Meta, TikTok, Snapchat and YouTube and produced a +1,900% increase in profitable ad spend and 51,889 customers profitably acquired. It contributed to a 9-figure exit. Spacemilk, a protein powder brand, ran Meta and Google and saw -35% cost per acquisition with +117% YTD revenue growth. Plant People ran Meta and Google and saw a 2.7x increase in subscription revenue.
Notice that every one of those names its channels and none of them is Meta alone. That is not a weakness in the proof. It is what honest proof looks like, and it's the standard to hold anyone else's case studies to.
Paul Kalka, Onnit's Director of Growth, has worked with Jeremy and me across several ventures. He put it this way: "They are experts in their craft and some of the best marketers I know." Ask whoever you're considering for a reference like that from someone in your category, then actually call them.
The first 90 days should go audit, then new creative, then the first real read on repeat customers. If someone skips straight to scaling spend in week one, they are guessing.
Week one: They check where your site sits in Meta's data categories and which events are restricted. They read every running ad against your label and confirm the ad account, pixel and page are owned by you. If that last one is messy, how to hand over an ad account walks through fixing it.
Weeks two through four: The first batch of genuinely new concepts goes live. Before it does, you agree in writing on the most you'll pay for a first purchase and how long each test gets before anyone calls it.
Days 30 to 90: The first group of new customers either reorders or doesn't. That's when you find out whether the account is buying customers worth keeping. The person running it should show you that cohort in your store's numbers, not just Ads Manager's.
You should also know what happens if it isn't working. With us, you approve the specific Unicorn Marketer before any work starts, you get a 14-day window to flag any communication problems and you can switch marketers or walk for any reason inside 60 days.
There is no honest universal price, so I'm not going to make one up. What you can control is what the fee buys. The common setups in 2026 are a flat monthly retainer, a percentage of ad spend, or a mix of both.
A percentage of spend has one problem you should know about. The person you're paying earns more when you spend more, whether or not the extra spend is profitable. That does not make them dishonest. It just means you should be the one deciding when spend goes up.
Whatever the structure, get these answers in writing:
If two partners quote the same fee, the one who makes more new creative and runs fewer accounts is the cheaper one. For the budget side, how much a supplement brand should spend on Meta ads works it out from your own first-order numbers.
The lesson: pick the person, not the logo. On a supplement account in 2026, the logo cannot read your label for you.
The Unicorn Assessment looks at your ad account, your creative and your funnel, then shows you what a top 1% ads expert would change before you commit to anything. If it's a match, you meet and approve the specific Unicorn Marketer yourself before any work starts.
The best one for you is whoever passes three tests: they've run supplement accounts before and can name the channels behind their results, they can rewrite your ads inside Meta's health rules on the spot, and they're managing few enough accounts to watch yours daily. A ranked list cannot tell you any of that. A 20-minute call with your own ads can.
It depends less on the label than on who does the work and how many accounts they run. An agency can be great if the senior person you met stays on your account. A freelancer can be great if they've worked inside supplement policy before. Ask both how many other brands they're running and who writes the creative.
Watch for a ROAS target quoted before anyone asks about your reorder rate, case studies that don't name the platform, a competing brand in your exact category and any promise to get claims approved that Meta's health rules don't allow. Each one says they're selling a template rather than looking at your business.
You'll see first-purchase costs within the first few weeks of new creative going live. The real answer takes longer, because you need the first group of new customers to reach their second order. Plan on judging the hire at around 90 days, using your store's numbers alongside Ads Manager.
Yes, for most brands. Meta's health and wellness standards, its personal attributes policy and the FDA's rules on structure/function claims all change what a supplement ad can say. Someone new to the category tends to learn those rules through rejected ads on your account, which costs you time and puts the account at risk.
You should, always. The ad account, the pixel, the Facebook page and every creative file should sit in your business portfolio, with the person you hire added as a partner. If the relationship ends, you keep the data and the history. Anyone who insists on running it from their own account is a risk.
