An Amazon SEO agency optimizes your product listings (titles, bullets, backend search terms, A+ content and images) so they rank higher in Amazon search and convert more of the shoppers who see them. The right agency pays for itself in organic sales. The wrong one costs twice. The wrong one rewrites your listings with the same AI tool you could have used yourself, and calls it strategy. I’d test for that early. If you want the basics first, our explainer on how Amazon SEO works covers them.
This guide compares 10 Amazon SEO agencies by the seller each one fits, explains what an Amazon SEO agency should actually deliver, and shows how to vet one before you pay. Every agency description was checked against that agency’s own website in October 2026. ZonHack is one of the ten, and we say so at the end.
What is Amazon SEO, in one minute
Amazon SEO means optimizing listings for Amazon’s search ranking, which weighs keyword relevance alongside how well a product sells: click-through, conversion and sales velocity. It differs from Google SEO in one decisive way. Amazon rewards listings that sell. Full stop. A keyword-stuffed title that wins impressions but not purchases tends to slide back down, which is why I’d never judge an Amazon SEO agency on keywords alone. Serious Amazon SEO pairs keyword placement with the conversion assets that turn a ranking into a sale: images, A+ content and a clear offer.
What an Amazon SEO agency should actually deliver
- Keyword research for your product, showing search terms, their relevance, and where you rank now.
- Rewritten titles and bullets that place priority terms naturally, within Amazon’s style rules.
- Backend search terms filled to the byte limit with terms not already on the page. Our guide to Amazon backend keywords explains the rules.
- Attribute and category fixes, since missing attributes quietly remove you from filtered results.
- Conversion assets, or at least a brief for them: main image, image stack and A+ content.
- Rank tracking on the agreed keywords, so you can see whether the work moved anything. No tracking, no proof.
Amazon SEO agency, SEO service or consultant? An agency usually does the work end to end and often runs ads too. An SEO service may sell a fixed deliverable, such as a listing rewrite. A consultant advises and you execute. Our guide to Amazon seller consulting covers when advice alone is enough.
How to vet an Amazon SEO agency before you hire
- Ask for keyword research on one of your own products before signing. I’d make this non-negotiable. A good agency shows real search terms and your current positions. A template deck tells you how the work will go.
- Ask how they handle images and A+ content. If the answer is “that’s not SEO”, keep looking. Rankings that do not convert do not last. Not for long. Our Amazon A+ content guidelines list what Amazon rejects, which makes a useful test question.
- Ask how results are measured, which I’d agree in writing: which keywords are tracked, from what baseline, over what period.
- Check Amazon’s own directory. The Amazon Service Provider Network lists vetted providers inside Seller Central, in categories that include Cataloging, Enhanced Brand Content and Imaging.
- Walk away from guaranteed page-one rankings. Nobody controls Amazon’s ranking. Not one agency. A guarantee usually means keyword stuffing, or worse, review manipulation that puts your account at risk.

No agency on this list except ZonHack publishes standard SEO pricing on its website. Expect a quote after a call or an audit. That is normal practice.
1. ZonHack
ZonHack’s listing optimization service covers keyword research, titles and bullets, backend attributes, A+ content design, and the product photography that decides whether a ranking turns into a sale. We are an Amazon Ads partner and an Amazon SPN Verified Partner, we have optimized 10,000+ listings, and listing work plugs into full account management when you want one team on everything.
Pricing: listing optimization starts at $149 per listing, with volume discounts and full-store packages for larger catalogs. Imagery and A+ production are quoted separately, because they vary so much by product.
Results published on our service page. A women’s beauty brand did $30,000 in its first year on Amazon with 4 SKUs. After launching 100+ SKUs with us, it was doing around $100,000 a month by the end of the following year. We used Amazon PPC and off-Amazon advertising to generate sales and improve organic ranking, and the previous year’s keyword data to target what worked. That is what connected SEO looks like, in my view: keywords, traffic and conversion working on the same plan. One plan, not three.
Best for: sellers who want listing optimization connected to advertising, images and account health, not a standalone rewrite.
Not for: a single one-off keyword report. Honestly, a freelancer is cheaper for that.
2. SalesDuo
A full-service Amazon agency that describes itself as “powered by proprietary AI tools and Amazon growth specialists”, with an AI tool it calls Ethan for listing monitoring. It says 85% of its teams come from Amazon experience.
Best for: established brands that want AI-assisted listing work at scale. I think the AI angle suits big catalogs best.
Services: Amazon SEO, listing optimization with keyword and competitor research, title, bullet and backend optimization.
Consider: I’d ask how much of the copy is written by people and how much by the tool, and who reviews it.
3. SellerApp
A software company that also runs managed services, so you can choose self-serve tools, a managed team, or both.
Best for: data-minded sellers who want dashboards alongside done-for-you listing and PPC work.
Services: listing optimization, keyword research tools, PPC management and DSP managed services.
Consider: personally, I’d want to enjoy dashboards before picking this route, since the software is a big part of the value.
4. Canopy Management
An Amazon-focused agency and an Amazon Ads Preferred Partner, offering full account management with SEO, listing optimization, and photography and video.
Best for: established brands with budget for a high-touch service across Amazon, Walmart and Chewy.
Consider: no pricing is published, and in my view its scale suits larger accounts better than new sellers.
5. Thrive Internet Marketing Agency
A general digital marketing agency with a dedicated Amazon practice covering Amazon SEO, advertising, DSP and Brand Store design.
Best for: businesses that want Amazon SEO plus Google SEO, web and social from one vendor. One contract, many channels.
Consider: Amazon is one practice among many. My question would be how many people work on Amazon accounts only.
6. My Amazon Guy
A full-service Amazon agency with a strongly educational style: a YouTube channel, webinars, an academy, and free ASIN video audits. It describes a “4-phase Amazon SEO plan”.
Best for: hands-on sellers who want to understand the work, not just receive it.
Consider: if you want white-glove service with no involvement, the teaching style may feel like homework. I’d count that as a strength for most owners.
7. Emplicit
A full-service marketplace agency working across Amazon and TikTok Shop, with listing optimization, PPC, inventory and account health management. It reports working with 450+ brands.
Best for: brands selling on both Amazon and TikTok Shop that want one agency for both. Honestly, that pairing is rarer than it should be.
Consider: SEO is one part of a broad service. Ask how much of the retainer goes to listing work specifically.
8. Vertical Rail
A “brand rep agency” for manufacturers and brands selling across many retailers, with clients it names including Motorola, Jabra and Wacom. SEO and copy sit inside a wider omnichannel service.
Best for: manufacturers that need Amazon handled alongside other retailers and retail media. Big-box retailers included.
Consider: it is built for omnichannel brands, so a small Amazon-only seller may not be the right fit.
9. WebFX
A large digital agency that describes itself as having “750+ digital experts” and a “30-year track record”. Its Amazon services include SEO, PPC, consulting, review management and marketplace launch.
Best for: businesses consolidating many marketing channels under one agency.
Consider: at that size, I’d ask who exactly will work on your Amazon account and how much of their time it gets.
10. Seller Interactive
A full-service Amazon agency that says it serves 1,300+ brands, offering SEO and listing optimization alongside PPC, account management, product launches, and suspension appeals and reinstatement.
Best for: sellers who want SEO plus help with account problems from one agency.
Consider: it starts with a free growth audit. Judge that audit the way you would any audit: does it name your actual listings and keywords?
Amazon keyword research agencies: what good work looks like
Plenty of sellers search for a keyword research agency specifically. Fair enough, and the work is worth judging on its
own, because it’s the foundation every listing and campaign is built on. Whichever agency you hire, good
keyword research should come back with:
| Deliverable | What it should show |
|---|---|
| A search term list for your product | Real shopper phrases, grouped by intent, with relevance judged by a person |
| Demand evidence | Amazon’s own data where available, such as Brand Analytics search frequency rank or your ad search term report |
| Your current position | Where your ASIN ranks and whether it’s indexed for each priority term |
| Placement | Which terms go in the title, bullets and backend search terms, and which belong in ads only |
| Exclusions | Irrelevant or competitor brand terms you should not target |
In practice, I’d judge this part hardest. Of the agencies above, ZonHack’s listing service includes keyword research, and SellerApp sells its own
keyword research tools alongside listing optimization. For the others, ask to see the keyword work on one of
your products before signing. Anyone can produce a long list. Lists are cheap. Judgment isn’t. The skill is cutting it down to the terms that
convert. You can check indexing yourself for free with our
keyword index checker, and our guide to
tools for Amazon SEO keyword ranking covers what you can do without
an agency.
A few signals separate careful researchers from volume merchants. Careful ones explain why a phrase was rejected, flag seasonal spikes, distinguish branded from generic demand, notice misspellings shoppers genuinely type, and revisit the work quarterly. Volume merchants paste spreadsheets, quote estimated monthly searches as gospel, and recommend stuffing every variant into the title. You’ll recognize the difference within one call. Trust that instinct.
The verdict
If you want listing optimization wired into ads, images and account management, ZonHack is our pick, and you can judge that against the published results above rather than our position on our own blog. If you want to learn the craft while it is done, My Amazon Guy fits better. Consolidating many channels? Thrive or WebFX.
My honest take: the agency matters less than whether SEO is connected to conversion work. I’d bet on that every time. A keyword-stuffed title with weak images ranks briefly and fades. Quietly, then completely. Whoever you hire, ask how they handle images and A+ content, and walk away from anyone who says rankings alone are the goal.
When the answer flips
- One-off listing rewrite on a tight budget → a vetted freelancer usually beats every agency here on price.
- You sell on Amazon and TikTok Shop → Emplicit covers both.
- You want software you control, with help on top → SellerApp’s tools-plus-service model fits.
- You sell through many retailers, not just Amazon → Vertical Rail’s omnichannel model is built for it.
FAQ
What does an Amazon SEO agency do?
An Amazon SEO agency researches the search terms shoppers use for your product, then optimizes titles, bullets, backend search terms, attributes and often images and A+ content so the listing ranks higher and converts better. Good agencies track rankings on agreed keywords to show whether the work moved anything.
How much does an Amazon SEO agency cost?
Pricing is usually per listing for one-off optimization, or a monthly retainer for ongoing work, and most agencies quote after an audit. ZonHack’s listing optimization starts at $149 per listing, with volume discounts and full-store packages; imagery and A+ content are quoted separately.
What’s the difference between Amazon SEO and Amazon PPC?
SEO earns organic rankings through keyword relevance and sales performance; PPC buys placement through ad auctions. They feed each other, because ad-driven sales help organic rank. Our comparison of Amazon advertising agencies covers the PPC side.
How long does Amazon SEO take to work?
Changes to a listing are usually indexed within days, but ranking movement typically takes several weeks, because Amazon weighs sales performance as well as keywords. Anyone promising page one in a week is describing advertising, not SEO.
Can I do Amazon SEO myself?
Yes, especially with a small catalog. Amazon’s search suggestions, a keyword tool and careful copywriting get you most of the way. Agencies earn their fee at scale, in competitive categories, or when your listings need photography and A+ work you cannot produce yourself.
What should an Amazon keyword research agency deliver?
A relevant search term list for your product, evidence of demand from Amazon’s own data where possible, your current rank and indexing for priority terms, and a plan for which terms go in the title, bullets, backend fields and ads.
How do I know if an Amazon SEO agency is legitimate?
Ask for keyword research on one of your own products, ask how they handle images and A+ content, agree how results will be measured, and check Amazon’s Service Provider Network. Avoid anyone guaranteeing page-one rankings or offering review schemes.
