How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- This is an agencies list: eight SEO companies that work with online stores, judged on e-commerce specialism. No agency can guarantee rankings or revenue, and any that promises a first page position by a date is telling you how it will treat every other promise. Behave accordingly and keep scrolling past such offers.
- E-commerce SEO is a distinct trade: category and product page strategy, faceted navigation control, product feed and schema work, and platform specific mechanics on Shopify, Adobe Commerce, BigCommerce and WooCommerce. Generalist SEO skill transfers only partly.
- Prices are quote based throughout, so the fields read See website. Real retainers for serious store SEO usually run from the low thousands of dollars a month upward, scaled by catalogue size and market competitiveness.
- Contract length and reporting transparency separate the adults from the churn merchants: monthly reporting against revenue adjacent metrics, and exit terms you can actually use, matter more than any pitch deck metric.

The best SEO companies for e-commerce

OuterBox is the first call for a store whose SEO problem is structural: platform, catalogue, navigation, the deep mechanics a content only agency cannot fix.
Ask who implements the technical recommendations and how fast. If the answer involves your developer's queue rather than their team, the specialist advantage shrinks; pin it in the proposal.
What we like- OuterBox is the purest specialist here: an agency built around e-commerce, offering SEO alongside store design and development for platforms including Shopify, BigCommerce, Adobe Commerce and WooCommerce. That combination matters because e-commerce SEO recommendations so often die waiting for a developer
- Here the people who audit can also implement. Its case material is store specific, catalogue sizes, category strategy, migration handling, rather than generic traffic charts.
Watch out for- A specialist's focus means broader brand and media services live elsewhere. Project queues in a design plus SEO shop can affect pace, a question to put directly. Pricing is opaque until scoping. Stores wanting a giant full service roster under one roof will find the menu narrower than WebFX or NP Digital.

Coalition suits the ambitious Shopify or BigCommerce store that wants a heavyweight team with platform specific pattern recognition across hundreds of stores.
Request the actual strategist's store portfolio, not the agency reel. Platform depth is real here, but it lives in individuals; contract for the individuals if you can.
What we like- Coalition Technologies, Los Angeles based, has one of the deepest Shopify SEO benches in the agency market, alongside BigCommerce, WooCommerce and Adobe Commerce work, backed by a large in house team and a long public record of store case studies. Its recruitment led scale means dedicated specialists per function: technical, content, digital PR. Stores on Shopify in competitive categories are its home fixture.
Watch out for- Scale cuts both ways
- Account team quality varies and the named team matters more than the brand. Its breadth across web design and paid media means SEO only buyers must keep scope focused. Time zone spread across a global team suits some clients and frustrates others. Retainers for competitive categories are substantial.

WebFX fits the multi brand or larger store that wants one accountable vendor, board grade reporting and SEO inside a wider digital programme.
Test the revenue reporting on your own analytics during the pilot. Attribution claims are the industry's favourite magic trick; the demo should reconcile with numbers you already trust.
What we like- WebFX is the industrial scale option: a full service digital agency of well over a thousand staff whose SEO offering plugs into its MarketingCloudFX reporting stack, which ties search work to pipeline and revenue attribution, the reporting store owners actually want. E-commerce is a major vertical, with platform experience across the majors and published pricing frameworks for many services that reduce the quote fog. Process maturity suits companies with procurement departments.
Watch out for- Published framework pricing still resolves to custom quotes for serious SEO programmes. A machine this size assigns accounts by tier, and smaller stores will not get its best people. Creative distinctiveness is rarely the selling point
- It sells system and scale. Long onboarding processes reflect its size.

Victorious is the process buyer's agency: you can read how the sausage is made before signing, and the reporting keeps showing you.
Ask for a sample quarterly roadmap for a store like yours. The document's specificity, page types, catalogue segments, revenue logic, predicts the relationship better than any reference call.
What we like- Victorious is an SEO only agency, which concentrates its mind: a documented methodology covering technical audits, keyword strategy mapped to page types, content and link acquisition, delivered with unusually explicit process transparency for the industry. It works with commerce brands among its client mix and publishes its approach in detail, letting a buyer diligence the method before the meeting. For owners burned by black box retainers, that openness is the product.
Watch out for- SEO only means paid, lifecycle and CRO help must come from elsewhere, a feature or a gap depending on your team. It is not the cheapest process on this list
- Rigour bills accordingly. Its e-commerce bench, while real, is less exclusively deep than OuterBox or Coalition. Enterprise scale programmes may stretch its model.

Ignite fits the established store ready to run search as part of an integrated growth programme rather than a siloed retainer.
Guard the SEO scope contractually for the first two quarters. Integrated agencies earn expansion; making them earn it keeps priorities honest while trust builds.
What we like- Ignite Visibility, San Diego based, runs SEO inside a broad digital practice, paid media, social, email, CRO, which suits stores whose growth problem spans channels and whose search strategy must coordinate with promotions and launches. E-commerce clients feature prominently in its case record, and its senior team is visible in industry education, a soft signal of genuine practice depth. Forecasting led planning is a house strength.
Watch out for- Breadth can dilute: the SEO bench, while strong, shares the stage with many services competing for your budget. Minimum engagements aim at mid market and up. Cross channel pitches can expand scope beyond the search problem you brought. As ever, the assigned team decides the experience.

Straight North suits the mid market store, or hybrid store and lead business, that has been hurt by vanity reporting and wants a vendor allergic to it.
Define the reporting contract in the agreement: which metrics, which cadence, which access to raw data. This agency will sign such terms happily; that willingness is itself the review.
What we like- Straight North built its name on accountability mechanics rare in SEO: lead validation and reporting that separates real prospects from noise, carried into its e-commerce work as a revenue minded reporting culture. It serves mid market companies across SEO, paid and web design from its Chicago base, with a long operating history and a sales process that talks business outcomes earlier than most.
Watch out for- Its commerce specialism is genuine but less platform deep than the top two here. Validation reporting shines brightest for lead generation
- Pure retail stores should test how it translates to transaction reporting. Scale is mid market by design. Brand recognition trails the coastal agencies despite the track record.

Siege is the authority builder: hire it when your technical house is in order and the gap is earning the links and coverage your competitors' content wins.
Sequence honestly. If your faceted navigation is broken, fix that with a specialist first; Siege's content cannot outrank a catalogue the crawlers cannot read.
What we like- Siege Media is the content specialist: an agency whose SEO engine is research driven content and digital PR that earns links, with a strong record for consumer brands and commerce adjacent publishers. For stores whose categories support real editorial, guides, data studies, comparisons, its work builds the authority that product pages alone cannot. Design quality of its content assets is visibly above the industry norm.
Watch out for- Content led means technical and platform SEO are not its core
- A store with structural problems needs those fixed first or elsewhere. Premium content pricing reflects the craft. Results compound over quarters, testing impatient owners. Product page and category strategy, the revenue core of store SEO, is outside its centre of gravity.

NP Digital closes the list as the board level option: the agency shortlisted when the store is a division, not a business, and the map is international.
Use its scale where scale is the problem, multi market coordination, stakeholder reporting, and negotiate experimentation rights for your core market team explicitly.
What we like- NP Digital, co-founded by Neil Patel, is the enterprise and global play: SEO at multinational scale, multi language and multi market programmes, supported by its Ubersuggest data tooling and a large specialist workforce. Big commerce brands use it when the programme spans countries, languages and stakeholder layers that smaller agencies cannot administer. Its content and technical arms are both substantial.
Watch out for- Enterprise orientation prices out most independent stores, and account attention follows account size. Tool led marketing can blur whether you are buying counsel or a software ecosystem. As with all the giants, the named team is the real product and must be diligenced as such. Agility on small catalogue experiments is not a giant's strength.
How we chose
We selected agencies with verifiable e-commerce practice, platform specialism across Shopify, Adobe Commerce, BigCommerce or WooCommerce, and public case material involving stores. Pure generalists without commerce depth and firms making ranking guarantees were excluded on principle. Pricing is unpublished across the category, so all fields read See website, with retainer context from agency market comparisons. No agency was engaged or paid, and no results are promised for any of them, which is the only honest way to write this category.
Buying guide: hiring an SEO agency without buying a story
Start with their questions, not their claims. A serious e-commerce SEO agency asks about your platform, catalogue structure, margins by category, stock realities and past migrations before it mentions traffic. An agency that pitches before diagnosing is selling a package, and packages are how stores get hurt.
Demand store specific evidence: case studies naming the platform, the catalogue size and the exact work, category restructuring, faceted navigation control, schema, content programmes, with revenue or at least transaction movement attached. Traffic screenshots without commerce context are decoration.
Contract for the exit and the evidence. Insist on monthly reporting you can audit, your own analytics as the source of truth, all content and links remaining your property, and a break clause after the first quarter. Agencies confident in compounding results accept these terms; agencies selling hope negotiate against them.
Finally, price the alternative honestly. An experienced in house SEO hire costs a senior salary and brings total focus on one catalogue; an agency brings breadth, tooling and pattern recognition across many stores. Stores above a certain catalogue complexity usually need both eventually. The agency that tells you where its own value ends is the one to hire.
Frequently asked questions
How much does e-commerce SEO cost in 2026?
Agency retainers for serious store SEO typically start in the low thousands of dollars per month and rise with catalogue size, market competitiveness and how much implementation is included, with enterprise programmes reaching well into five figures monthly. One off technical audits and migration support are usually project priced. Any quote far below the market for a competitive category is buying very little work, whatever the proposal says.
How long before SEO results show?
Technical fixes can recover lost ground within weeks of deployment and recrawling. New content and authority building compound over three to six months before revenue movement is reliably visible, and competitive categories take longer. This timeline is precisely why contracts should judge agencies on leading indicators early, crawl health, indexation, category rankings, while holding revenue judgement for later quarters.
Can an agency guarantee first page rankings?
No, and the claim itself is the industry's most reliable red flag. Rankings depend on Google's systems, competitor actions and your own site's state, none of which an agency controls. What a good agency can guarantee is process: the audits it will run, the work it will ship, the reporting it will stand behind. Buy those guarantees in writing and treat ranking promises as disqualifying.
What should an agency handle on Shopify specifically?
Shopify SEO has platform specific mechanics: its fixed URL structures, collection and tag duplication, theme level schema, app bloat effects on speed, and the limits of its native blogging. An agency with real Shopify depth will raise these in the first conversation, along with workarounds it has shipped before. Generic audits that ignore the platform's constraints produce recommendations your store literally cannot implement.
Should I hire an agency or an in house SEO?
An agency buys breadth, tooling and cross store pattern recognition; an in house hire buys focus, speed of iteration and product knowledge. Smaller stores usually start with an agency or a strong freelancer, add in house ownership as search revenue justifies it, and keep the agency for specialist work like migrations and digital PR. The ownership of strategy and data should live in house from the start, whoever executes.
