Supplements & Health on Amazon
Amazon PPC for Supplement Brands. Built Around What the Category Actually Requires.
SellTru manages Amazon advertising for supplement, vitamin, and health brands doing $500K to $10M. Compliance-aware ad strategy, high-competition keyword management, and Subscribe & Save optimization built around supplement category dynamics, not a generic agency playbook.
The Real Problem
Supplements Is One of the Hardest Amazon Categories to Get Right
High CPCs, strict compliance rules, and a crowded shelf make it easy to burn budget and see nothing for it.
Agencies that don't know compliance constraints. Supplement ad copy has strict rules. Disease claims, drug-like language, and certain health benefit claims get ads rejected or pulled mid-campaign. Agencies that don't know where the line is either play it so safe the copy doesn't convert, or they run copy that gets flagged and takes your campaigns offline. Either way, you're paying for it.
Bidding on broad terms that will never be profitable. Broad supplement keywords like "protein powder," "vitamin C," or "collagen peptides" have CPCs that make profitability nearly impossible for most brands without massive volume. The brands building sustainable supplement businesses on Amazon are winning on ingredient-specific, dose-specific, and use-case-specific long-tail terms with lower CPCs and buyers who already know what they want.
Ignoring Subscribe & Save as an acquisition goal. A supplement customer who subscribes has an LTV that is 3 to 5 times higher than a one-time buyer. Most agencies optimize for first-order ROAS and stop there. They're not thinking about which keywords attract Subscribe & Save buyers, how to structure product page copy to encourage subscription, or how to adjust ACoS targets when the LTV math looks different for subscribers vs. one-time purchasers.
What We Manage
Full Amazon Advertising, Built for Supplement Brands
Every ad type managed together, with strategy built around supplement category compliance, CPCs, and subscriber acquisition.
Sponsored Products
The core Amazon PPC format. We build campaign structures with auto campaigns for discovery, manual exact campaigns for proven keywords, and ingredient-specific and use-case-specific campaigns targeting the long-tail terms where supplement brands find the most profitable traffic. Weekly bid management, not quarterly reviews.
Sponsored Brands
Brand-level placements at the top of Amazon search. In a category where brand trust matters, Sponsored Brands campaigns reinforce credibility and positioning alongside purchase intent keywords. We handle headline copy within Amazon's supplement advertising guidelines, product selection, and store page routing.
Subscribe & Save Optimization
For supplement brands, subscriber LTV changes the entire ROAS calculation. We build campaigns that specifically target keywords and placements where Subscribe & Save conversion rates are highest, and we track subscriber acquisition as a primary performance metric alongside ROAS and TACoS.
Compliance Review
Before any ad copy goes live, we review it against Amazon's supplement and health product advertising policies. No disease claims, no drug-like language, no unsubstantiated benefit claims. We also flag listing copy issues that could trigger a policy review or cause a listing suppression that stops all ad spend cold.
Search Term Mining
We pull search term reports every week. High-converting ingredient-specific and use-case-specific terms get harvested into exact match campaigns. Irrelevant terms get negated. In a competitive supplement category, this ongoing process is what separates accounts that get more efficient over time from ones that keep paying for the same bad traffic.
Monthly Reporting
Clear monthly performance reports showing ROAS, TACoS, revenue trend, ad spend efficiency, and Subscribe & Save acquisition data. We track the metrics that tell you whether the account is building long-term value, not just short-term ROAS numbers that look good on paper but miss the subscriber story.
How We Run It
The 90-Day Amazon PPC Process for Supplement Brands
Every engagement starts with a full audit covering campaigns, compliance, keyword coverage, and Subscribe & Save baseline.
Days 1–14: Full Account and Compliance Audit
We pull your campaign data, search term reports, bid history, wasted spend, and active ad copy. For supplement brands we also review all ad copy against Amazon's advertising policies and flag any claims that could cause rejections or account flags. You get a written findings doc before we change anything.
Days 14–30: Rebuild Campaign Structure
We rebuild the campaign architecture from scratch or restructure what exists. Separate campaigns by match type, ad groups segmented by ingredient, formula type, and use case, Sponsored Brands campaigns for brand defense, and negative keyword lists built from your existing search term data to stop wasted spend immediately.
Days 30–60: Baseline and Initial Optimization
With clean structure running, we let campaigns gather data. Weekly: search term pulls, negative additions, bid adjustments on keywords with enough data to act on. Month-end: campaign type review, budget pacing, TACoS trend, and Subscribe & Save acquisition baseline. First optimization report at day 45.
Days 60–90 and Ongoing: Scale What Works
By day 60 you have real data. We identify which keyword categories and campaign types are driving the best ROAS and subscriber acquisition rates, which products have conversion rates worth scaling behind, and where listing or image gaps are capping performance. A great campaign structure can't compensate for a product page that doesn't convert.
Why SellTru
We're Not an Agency Running Supplements the Same Way We Run Hardware
Category expertise matters. Supplement brands need an agency that understands compliance, LTV, and the competitive keyword landscape.
Ad copy compliance reviewed before every launch
Every headline and description gets reviewed against Amazon's supplement advertising policies before it goes live. No disease claims, no drug-like language, no ads pulled mid-campaign. We also flag listing copy issues that could trigger a suppression and shut down all ad spend on a product cold.
Ingredient-specific targeting, not broad category terms
Broad supplement terms have CPCs that make profitability nearly impossible for most brands. We build campaigns targeting ingredient-specific, dose-specific, and use-case-specific terms where purchase intent is high and CPCs are lower. That's where sustainable supplement growth lives on Amazon.
Flat retainer, not percentage of spend
We charge a flat monthly fee, not a percentage of ad spend. Our incentive is to get you the best ROAS, not to run your budget up. Percentage-of-spend pricing creates a structural conflict of interest we don't have.
Weekly management, monthly reporting
We review every active account every week. A competitor launch, a trending ingredient, or a policy update can shift supplement category dynamics fast. Weekly management catches changes before they become expensive problems.
One account manager, not a handoff chain
You work with one person who knows your account, your formulas, and your compliance constraints. Not a sales rep who closed you and a junior analyst who manages the account. The person doing your weekly optimization is the person on your monthly calls.
Honest audits before any commitment
We audit your account covering campaigns, compliance, keyword coverage, before you decide whether to work with us. You see exactly what's wrong and what we'd fix. The audit quality tells you more about our expertise than anything we'd say in a pitch.
