A shopper looking for a supplement may never see your website. They ask ChatGPT, they skim an AI Overview, they tap into Rufus on Amazon, and three brands get named. If yours is not one of them, the sale happened somewhere you cannot see in Shopify analytics.
Here are the seven best GEO agencies for supplement brands in 2026, ranked: 95 Projects, NoGood, Common Thread Collective, Single Grain, Inflow, Pilothouse, and Power Digital. Budgets across this list run from roughly $3,500 per month at the low end to $50,000 or more per month at the high end.
Below you will find a side-by-side comparison table and a full review of each agency with pricing, pros and cons.
Generative Engine Optimization (GEO) is the practice of making your brand recommended by AI answer engines: ChatGPT, Perplexity, Claude, Gemini, and Google AI Overviews. For supplement brands, this is no longer optional. Consumers are asking ChatGPT for ingredient guidance, using Perplexity for third-party testing comparisons, and getting curated brand shortlists from Claude before they ever click an ad or read a label.
The supplement brands appearing in those AI-generated recommendations are winning the new top of funnel. The supplement brands that are not, are quietly losing customers who never touch a search results page or a paid ad.
GEO matters for supplement brands specifically because:
This guide is built for supplement brands in the $1M to $50M annual revenue range that need search marketing producing revenue, not just rankings or ad impressions.
We reviewed each agency as of September 18, 2026, using their own site and published service pages, their Clutch profile, and third-party reporting. Below are the four things we weighted, all of them specific to how supplement and consumer health brands actually grow.
Plenty of agencies added “AI search” to the service menu in 2026 without changing what they do. We gave weight to agencies that meet three tests:
Most candidates never get past this one.
A supplement shopper does not prompt the way a software buyer does. They ask about ingredient forms, like magnesium glycinate versus oxide. They ask whether the dose matches the studies, whether the product is NSF Certified for Sport or USP Verified, and whether the COA is actually published.
The agency also has to know what you cannot say under FDA structure/function rules, and what FTC substantiation requires before anything goes live. We favored agencies with real client work in supplements and adjacent consumer health over generalists who would learn on your budget.
Your customer moves between a Google AI answer, a Reddit thread, your Shopify PDP and a Rufus question on your Amazon listing. Agencies that treat GEO as a separate retainer tend to leave the listing content, the paid landing pages and the review corpus untouched. We preferred teams running all of it as one program.
Citation counts and share of voice in AI answers are diagnostics, not results. We weighted agencies that report against:
95 Projects is a search marketing agency founded in January 2022 that runs SEO, PPC and GEO as one practice rather than three separate service lines with three separate reports. For a supplement brand, that matters because the same asset does triple duty. A PDP that explains ingredient form and clinically studied dose well enough to earn an AI citation is also the page that has to convert paid traffic and hold a position on a category query.
The pattern across these accounts is the same. Build a topical authority cluster the AI engines can cite confidently, then layer paid channels on top once the organic and AI citation flywheel is moving.
95 Projects works with supplement brands in three integrated phases, designed to be revenue-attributable from month one.
Phase 1: GEO foundation and citation surface area. The agency audits where the brand currently appears (or fails to appear) in ChatGPT, Perplexity, Claude, and Gemini for category-defining queries. From the audit, the team builds a topical authority map of the editorial, product, and resource content needed to become citable on ingredient, third-party testing, compliance, and competitor-alternative queries. The first 30 to 60 days are heavily weighted toward citation-surface buildout.
Phase 2: SEO and content depth. Once AI engines have something to cite, traditional SEO compounds the gain. The same content earning AI citations earns organic rankings, and the two channels reinforce each other. 95 Projects runs proprietary keyword and topic research for the supplement brands buyer journey, separating informational queries from commercial queries.
Phase 3: Paid acceleration with attribution. Once organic and AI search are producing revenue, paid media runs against the proven topical clusters at known cost per acquisition. Meta, Google Shopping, and TikTok ads are layered in to scale the volumes the brand already knows convert. The integration prevents the most common failure mode, which is paying to acquire customers the brand could have earned through organic and AI search at a fraction of the cost.
95 Projects runs all three phases under one team, with one founder accountable to revenue. The agency takes on a small number of engagements per quarter to maintain founder involvement on every account.
$5,000 to $20,000 per month, published on the site. Scope moves with catalog size and how much of the budget goes to paid.
NoGood is a performance marketing agency with a deep DTC and SaaS portfolio and one of the earlier publicly stated AEO (Answer Engine Optimization) practices in the industry. The agency leans creative-forward, with strong work across fashion, beauty, lifestyle, B2B SaaS, and DTC food categories.
For brands that want a creative-heavy paid partner with a genuine AEO offering, NoGood is one of the cleaner fits in the market. Pricing tends toward the higher end of mid-market.
Not published. Industry reporting puts retainers around $15,000 to $25,000 per month, and third-party directories list a $50,000 minimum project size.
CTC in Costa Mesa is the agency to talk to if your core problem is that nobody can tell you what your media is actually earning. The whole practice is built around forecasting, contribution-margin reporting and incrementality testing. A single “Prophit Engineer” owns forecast, media and creative for the account instead of splitting them across three pods. For a brand managing to MER and new-customer CAC, that discipline is worth real money.
The reason it sits third rather than first for a GEO search: as of September 2026, the service menu covers growth strategy, Meta ad buying, Google ad buying, ad creative and incrementality, with no dedicated GEO or AEO service line.
Published in CTC’s own 2026 pricing guide. Seven-figure brands run $5,000 to $15,000 per month, eight-figure brands $15,000 to $50,000 per month. PE Lite, aimed at sub-seven-figure brands, is $1,500 onboarding plus $500 per month, month-to-month.
Eric Siu’s agency has put public weight behind GEO and the broader “search everywhere optimization” idea, and it runs SEO, PPC, content and GEO together, which is the right shape for this problem. Named clients include Amazon, Uber, Salesforce and Nextiva, and the Clutch rating sits at 4.8 out of 5 across 12 reviews.
The tradeoff is focus. Single Grain is a generalist that works across many verticals. Expect to bring the category knowledge yourself: ingredient forms, dosing, structure/function claim limits and subscribe-and-save economics. GEO is part of the offer, not the organizing principle of the agency.
Not published. Clutch lists a $10,000 minimum with engagements running $10,000 to $50,000 or more per month.
Inflow is ecommerce-focused and has one structural choice worth paying attention to: no account managers. Clients work directly with the senior specialists doing the work, which for a lean team means fewer status calls and faster decisions. Services cover SEO, PPC, paid social and CRO. It holds Google Premier Partner, Meta Business Partner, Microsoft Advertising Partner and Buy With Prime Agency Partner status. Its Clutch PPC focus includes Amazon Advertising, which matters if your marketplace revenue is material.
Clutch shows 4.9 across 12 reviews, a $1,000 minimum project and hourly rates of $150 to $199. A long-time client reported annual spend of roughly $24,000 to $80,000, and third-party reviews cite monthly pricing starting around $3,500 to $4,000. Clients named in reviews include KEH, Gaia, Aviator Gear and Shore Excursions Group.
From roughly $3,500 to $4,000 per month, with a $1,000 minimum project and $150 to $199 hourly. The most accessible option on this list.
Pilothouse, founded in Victoria BC in 2019, is a full-funnel DTC performance shop. It has in-house media buyers across Meta, Google, TikTok, Amazon and YouTube, plus creative teams producing UGC, ad creative and email and SMS design. Client names include Benchmade, Hestan Culinary, Big Blanket Co, Chamberlain Coffee and General Mills. For a supplement brand whose growth is currently paid-social-led and creative-constrained, this is a strong operational fit.
For GEO specifically it is a weak fit. Third-party reviewers report that AI search is not a current focus, and SEO and content are not core to the offer. You would be buying creative velocity and media execution.
Not published. Third-party estimates put base retainers at $10,000 to $25,000 or more per month, sometimes structured as a hybrid with a percentage of revenue or ad spend.
Power Digital, founded in San Diego in 2012, is the largest option here. It runs on a proprietary data platform called nova. It covers SEO, content, paid, social, programmatic and CTV, PR, influencer, email and SMS, CRO, retail marketing and creative. Named clients include Honest, Bob’s Red Mill, Casper and MyFitnessPal, so there is real consumer health and CPG experience in the portfolio. That includes retail work, which matters if you are moving into brick and mortar.
As of April 2026, an independent reviewer noted that AI search optimization is not documented as a distinct service line. At this size you also accept more handoffs and less senior attention unless your spend justifies it.
Custom retainers. Clutch lists a $5,000 minimum project and $100 to $149 hourly.
Rufus visibility is not a side project for you. NoGood is the only agency here that tracks it inside a measurement platform. Inflow brings real Amazon Advertising and Buy With Prime experience at a much lower price. 95 Projects fits if you want the Shopify catalog and the off-Amazon AI recommendations handled together. Marketplace ranking and language model recommendations both feed on the same inputs: clear ingredient detail, published COAs, third-party certifications like NSF Certified for Sport or USP Verified, and reviews.
This is where a search-led agency earns its retainer. PDPs and collection pages are your inventory of answerable pages. Each SKU variation, ingredient form and dose is a query someone is typing into a chat window. 95 Projects and Single Grain are the two integrated search options. At a smaller budget, Inflow.
Pilothouse for creative volume, or CTC if the bigger problem is that your MER and new-customer CAC numbers do not reconcile. Neither will move AI visibility, so plan on a second partner or an internal owner for that work.
Power Digital, with GEO scoped separately and held to its own reporting.
As of September 18, 2026, GEO and search agency pricing for supplement brands ranges from about $3,500 per month at the entry level to $50,000 per month for 8-figure, multi-channel programs, before ad spend. Only 95 Projects and Common Thread Collective publish pricing. The rest require a discovery call, so the figures below combine published pricing, Clutch profile data, and third-party reporting.
Run the retainer against contribution margin per new subscriber, not against traffic. Illustrative numbers, swap in your own:
Say AOV is $65 and contribution margin after COGS, shipping, payment processing and fulfillment is 50%, so about $32 per order. Subscribe-and-save churn puts the average subscriber at 4.2 orders before cancellation, which is roughly $136 of contribution per new subscriber. An $8,000 monthly retainer needs about 59 incremental new subscribers per month to cover itself, and around 175 to return 3x on the fee.
Payback matters more than the multiple. If new-customer CAC on paid is at or near that $32 first-order contribution, you are funding growth out of month two and beyond, which means retention assumptions carry the whole model. AI-sourced and organic customers usually come in at a lower acquisition cost. That is why shifting even a few points of new-customer mix into those channels moves blended MER more than another creative test will.
Time the spend to your calendar. Content and citation work built in September and October is what ranks and gets recommended during January. That is when sleep, weight management and immunity demand spikes and paid CPMs are still recovering from Q4. Starting that work in January means paying peak media prices to cover for organic visibility you did not build in the fall.
SEO optimizes for a page that ranks and gets clicked. GEO optimizes for your brand being named inside an answer that may never send a click at all.
The click math has already moved. Search Engine Journal reported on April 27, 2026, on a randomized field experiment by Agarwal and Sen of ISB and Carnegie Mellon (source). It found that Google AI Overviews reduced organic clicks by 38% on queries where they appeared, with zero-click results climbing from 54% to 72%. The paper is a working paper and not yet peer reviewed, but the direction matches what most Shopify brands are seeing in Search Console.
Health is ahead of the curve on this behavior. The KFF Tracking Poll on Health Information and Trust was fielded February 24 to March 2, 2026 with 1,343 US adults. It found 32% had used AI chatbots for health information in the past year, the same share that uses social media for it. KFF also points out that many people encounter AI-generated health information through search engine summaries without ever seeking it out.
What actually influences those answers is partly known. The paper “GEO: Generative Engine Optimization” by Aggarwal and collaborators at Princeton was presented at KDD 2024. It found that GEO techniques lifted visibility in generative engine responses by as much as 40%. Citations, direct quotations and statistics did the heaviest lifting, and results varied by domain. For supplements that translates cleanly: cite the clinical literature behind your ingredient form and dose, publish your COAs, state your certifications, and quote real third-party sources on the page.
The practical work looks like this. Instead of chasing a head term like “magnesium supplement,” you cover the way people actually phrase it in a chat window. Examples: best third-party tested magnesium glycinate for sleep, is magnesium citrate or glycinate better absorbed, which creatine brands are NSF Certified for Sport, what dose of ashwagandha was used in the studies. Each of those is a question your PDP or a supporting page should answer directly, in the first two paragraphs, in language a model can lift.
Collection pages stop being SKU grids and start being comparison pages that explain differences between forms. Off-site citations in publications a model already trusts matter more than they ever did for classic SEO rankings. That is why digital PR sits inside a GEO engagement rather than next to it.
Measurement changes too. You will not get a clean click path from a ChatGPT recommendation. Post-purchase attribution surveys asking how customers first heard about you will tell you more than any dashboard, especially read alongside direct and branded search volume. Imperfect signal you actually act on beats a tidy report that tracks nothing that matters.
This is the part that disqualifies most generalist agencies. Supplement copy lives inside FDA structure/function claim limits. You can describe support for normal function, but not treatment, prevention or cure of any condition. Every claim also needs FTC-level substantiation behind it. Paid social and Google add their own health claim restrictions on top, which is why so many supplement accounts get disapprovals that nobody on the media side can explain.
Language models will happily repeat whatever your page says, and that cuts both ways. Sloppy claim language written to win an AI citation becomes a documented, screenshot-able liability, and it is the fastest way to get an ad account restricted.
The safer and more effective path is the one the research already points to: substantiated ingredient detail, published dosing that matches the studies, certifications named explicitly, COAs linked, and sourcing described plainly. That content is compliant, and it is also exactly what gets cited. It gives a model the specific, verifiable material it needs to recommend you over a competitor making vague promises.

GEO, or generative engine optimization, is the work of getting your brand named and cited inside answers from ChatGPT, Google AI Overviews, Perplexity and Amazon Rufus. For a supplement brand it means structuring PDPs and collection pages around real shopper questions: ingredient forms, clinically studied doses, third-party testing and certifications. It also means earning citations in publications those engines already draw on.
Across this list, roughly $3,500 to $50,000 or more per month. Integrated search engagements for brands in the $1M to $50M range typically land between $5,000 and $20,000 per month. Only 95 Projects and Common Thread Collective publish their rates.
Yes, and Rufus is the reason. Marketplace AI recommendations pull on the same inputs as off-Amazon engines, including ingredient specificity, certifications such as NSF Certified for Sport or USP Verified, published COAs and review quality. Work that improves one usually improves both.
It varies by category competitiveness and how much authority your domain already has. Documented work in consumer categories has produced first-position AI recommendations for category queries within a few weeks. Broader compounding across a full catalog is a multi-quarter effort. Plan for the work to be in place before January and Q4 demand peaks rather than during them.
Use post-purchase attribution surveys asking how customers first heard about you, and watch direct and branded search volume alongside them. Chat-sourced traffic frequently arrives as direct or branded, so channel reports will undercount it. Hold the agency to new-customer CAC and contribution margin rather than citation counts.
