Every few weeks, another "Top 10 Supplement Marketing Agencies" list shows up in your feed.

They all look the same. A logo grid. A short blurb. A "book a call" button.

But none of them tell you how to actually judge an agency once you're on a real sales call with one.

That's the problem we want to solve in this post. Instead of handing you another ranked list, we're giving you the scorecard we'd want a supplement brand to use on us, and on anyone else you're considering.

Why "Top 10" Lists Don't Actually Help You Choose

Most agency ranking posts are built one way.

An agency writes about itself, mentions a few "competitors" for SEO purposes, and ranks itself near the top.

That's not dishonest exactly. But it's not useful either.

It tells you who spends money on content marketing. It doesn't tell you who will actually run compliant, profitable ads for your specific supplement brand, at your specific stage.

We've written before about how to evaluate an agency's case studies, because that's usually where the inflation happens first. This post goes a level deeper: the actual scorecard to run during your discovery calls.

The 7-Point Supplement Agency Scorecard

Score each agency 1 to 5 on every category below. Anything under a 4 average is a yellow flag worth pushing on before you sign.

That last row matters more than people think. We've actually written a full post on why we turn some supplement brands away, and what that means for the ones we do take on.

Question 1: How Do You Handle Compliance Before Launch?

This is the single most important question for any supplement or health brand.

Meta and TikTok both suspend supplement ad accounts constantly, usually over claim language, not creative quality.

If an agency can't describe their exact review process, that's a real warning sign.

We've written a full recovery playbook for brands who already got hit with this, which is worth reading even if you haven't been restricted yet: Meta Ad Account Restricted for Supplement Claims?

Question 2: What Happens in the First 90 Days?

Ask for a week-by-week answer, not a vague "we'll get to know your brand" response.

A good agency can tell you exactly when the first ad goes live, when the first creative test batch launches, and when you'll see your first real report.

We laid out our own version of this timeline here: What to Expect in Your First 90 Days With a Supplement Marketing Agency.

Question 3: Who Actually Owns the Ad Account?

This one gets skipped constantly, and it's expensive when it does.

Some agencies build campaigns inside their own business manager, not yours.

If you ever leave, your pixel data, audiences, and ad history leave with them, not with you.

We go deep on this exact risk in Who Should Own Your Ad Accounts?, including the specific questions to ask before you hand over access.

A Simple Checklist for Your Next Discovery Call

Bring this list into your next agency call. Ask the questions out loud and watch how confidently they answer.

1. Can you show me a live client dashboard, not a screenshot?
2. What's your average time to launch a first ad set?
3. Who owns the ad account and pixel data if we ever part ways?
4. How many new creative concepts do you test per month?
5. What's your exact review process for supplement claim language?
6. What's the contract length, and how do we exit if it's not working?
7. What kind of brand would you turn away, and why?

Where Does Price Fit Into the Scorecard?

Notice that price isn't one of the seven categories above. That's on purpose.

Price matters, obviously. But it's a filter you apply after the scorecard, not instead of it.

Two agencies can charge the exact same $2,500 a month retainer and deliver completely different results, depending on how they score on compliance, creative pace, and reporting.

The bigger question is usually how an agency prices, not just how much.

A flat retainer, a performance-based cut of ad spend, and a hybrid model all create different incentives for the team managing your account.

We broke down the tradeoffs of each pricing model in detail here: Retainer vs. Performance-Based Pricing. Worth reading before your next call so you know which questions to ask about how their fee actually works.

Red Flags to Watch For Beyond the Scorecard

A few more warning signs worth flagging, beyond the seven questions above.

Pressure to sign same-day. A real agency partner wants you to feel good about the decision, not rushed into it.

No mention of TikTok Shop. By 2026, most serious supplement brands need at least a plan for it, even if it's not the first channel launched. We covered whether it's worth adding to your ad mix here.

Case studies with no context. A screenshot of a ROAS number means nothing without spend level, timeframe, and starting point. Again, our case study evaluation guide walks through exactly what to ask for.

We'll say this plainly, because it needs saying: a supplement brand that ends up in a bad agency contract usually knew something felt off during the sales call. Trust that instinct.

How eBrandX Approaches This Differently

We built our process assuming brands would run this exact scorecard on us. So here's where we land on each line.

We manage Amazon, Meta, and TikTok Shop under one team, so you're not stitching together three separate vendors.

You keep ownership of your own ad accounts, always. Compliance review happens before a claim ever goes live, not after a suspension notice shows up.

And we're honest when a brand isn't ready for us yet. That's not a sales tactic. It's just how we've built long client relationships across 300+ brands.

If you want to see how eBrandX scores against this exact framework, on a call, with your own brand's numbers in front of us, book a free strategy call here.

If you'd rather learn the frameworks yourself first, alongside 75,000+ other supplement and ecommerce operators, our Supplements Scaling Insiders community covers this exact scorecard in more depth, along with templates and SOPs you can use on your own team.

The Bottom Line

A ranked list can tell you who has a good marketing budget.

Only a real scorecard, run on a real call, can tell you who's right for your brand.

Print the seven questions above. Bring them to your next call, whether that call is with us or with someone else.

A good agency will welcome the scrutiny. That's usually the fastest way to tell the difference.
