Top 10 B2B eCommerce SEO Agencies for 2026

Any SEO agency can find keywords and recommend a few blog posts, but that doesn’t make them a strong B2B eCommerce SEO partner.

The best B2B eCommerce SEO agencies understand how large product catalogs behave in search. They know when filtered URLs should be indexed, they can fix duplicate product pages without removing valuable search demand, and they also understand that a Request For Quote (RFQ) matters more than one hundred extra visits.

We work with these problems every day, so broad promises don’t impress us. We’ve seen plenty of “best eCommerce SEO agency” lists, but most focus heavily on B2C stores. So we decided to create something more specific. Below are ten SEO agencies for B2B eCommerce companies that you should consider.

B2BSEO.io

B2BSEO.io is a specialized B2B eCommerce SEO agency that takes the #1 spot in our list. The agency builds its strategies around longer buying cycles, multiple decision-makers, complex product catalogs, bulk orders, distributor relationships, and conversions such as quote requests, calls, and sales inquiries.

Their work covers technical SEO, product and category architecture, faceted navigation, keyword mapping, internal linking, comparison and use-case pages, content, and link-building.

The team also looks beyond Google rankings by checking how clients appear in AI-generated answers and the third-party sources those platforms reference.

Best match: B2B eCommerce companies with complex catalogs, long sales cycles, and quote or inquiry-based conversions.

Core work: Technical SEO, category and product optimization, site architecture, content, internal linking, digital PR, and AI search visibility.

Working style: Founder-led, hands-on, and focused on qualified traffic, leads, and revenue rather than templated reports.

Pricing: Custom monthly retainers based on website size, competition, and the required content and link-building work.

Strongest point: Deep B2B specialization combined with practical experience on large and technically complex websites.

Industries: Manufacturing, industrial products, heavy equipment, healthcare, fintech, SaaS, and technology.
What Earned Them a Spot

Many eCommerce SEO agencies are still built mainly around consumer stores. B2BSEO.io stood out for understanding how product discovery works when buyers are comparing suppliers, reviewing technical specifications, involving multiple decision-makers, and submitting an RFQ instead of completing an online checkout.

Their B2B focus, hands-on strategy, and strong collection of case studies and client reviews earned it the top position.

Who We’d Recommend Them For

We would recommend B2BSEO.io to manufacturers, industrial suppliers, specialized marketplaces, and other B2B eCommerce companies with complex catalogs and longer sales cycles.

They’re an especially good fit for companies that want direct senior involvement and care more about qualified inquiries, pipeline, and revenue than traffic alone.

OuterBox

OuterBox is a large eCommerce SEO and development agency with real B2B capability. Their team works across search, CRO, paid media, analytics, design, and development.

Best match: Established B2B eCommerce companies with large or technically complex catalogs
Core work: eCommerce SEO, AI search, content, CRO, paid media, analytics, design, and development
Working style: Integrated specialist teams with in-house development support
Pricing: Custom, based on the scope
Strongest point: Their ability to implement technical SEO recommendations in-house
Industries: B2B eCommerce, manufacturing, automotive, healthcare, retail, and industrial products

What Earned Them a Spot

OuterBox earned a spot because they can diagnose an SEO problem and deploy the fix. This is particularly important on stores where faceted navigation, platform limitations, weak templates, or poor catalog architecture require development work.

Their results are not limited to traffic. OuterBox reports increasing CORSA Performance’s organic search revenue by 366% and total revenue by nearly 300%.

Who We’d Recommend Them For

Established B2B eCommerce companies with large catalogs or serious technical debt are the strongest match. OuterBox also makes sense when SEO overlaps with a redesign, migration, CRO program, or custom integration.

TopSpot

TopSpot is a B2B and industrial digital marketing agency that has worked with manufacturers, suppliers, and distributors since 2003. Their eCommerce work combines technical SEO, content, CRO, paid search, analytics, and web development. The agency’s specialty is industrial demand generation, not general online retail.

Best match: Manufacturers, suppliers, and distributors with eCommerce or online catalogs
Core work: B2B SEO, eCommerce SEO, content, PPC, CRO, analytics, and web development
Working style: Data-heavy and organized around dedicated customer relationship teams
Pricing: Custom, based on the scope
Strongest point: Understanding industrial search intent and measuring lead quality
Industries: Manufacturing, distribution, industrial services, energy, software, and healthcare

What Earned Them a Spot

TopSpot made the cut for one simple reason: they understand industrial search behavior. Their strategies account for part numbers, product specifications, regional demand, RFQs, and long sales cycles.

They also measure lead quality instead of hiding behind pageviews. TopSpot reports that their work for Rapid Rivets & Fasteners increased site conversions by 155% within six months.

Who We’d Recommend Them For

We would recommend TopSpot for manufacturers and distributors that sell technical products or generate quotes through an online catalog. They are also a strong option when SEO must work alongside paid search and conversion tracking.

Companies looking for a pure retail eCommerce agency should consider someone else.

1Digital Agency

1Digital Agency focuses almost entirely on eCommerce. Their B2B practice works with manufacturers, wholesalers, distributors, and OEMs. The team understands Shopify Plus B2B, BigCommerce B2B Edition, Adobe Commerce, and WooCommerce.

Best match: B2B sellers that need SEO and platform development from one agency
Core work: eCommerce SEO, AEO, GEO, PPC, design, development, and platform migrations
Working style: Senior-led with a US-based core team and vetted global specialists
Pricing: Published packages range from $899 to $5,999 per month; custom scopes are also available
Strongest point: Platform-specific experience across major B2B eCommerce systems
Industries: Manufacturing, wholesale, distribution, industrial products, specialty retail, and food and beverage

What Earned Them a Spot

1Digital Agency belongs on this list because their B2B eCommerce expertise goes far beyond a generic service page. Their team discusses spec-led taxonomies, customer-specific pricing, bulk-order rules, gated accounts, CAD files, safety documents, and certifications.

Their platform specialists can also implement technical recommendations instead of leaving the client with another long audit document.

Who We’d Recommend Them For

The agency should sit near the top of the shortlist for B2B sellers running Shopify Plus, BigCommerce, Adobe Commerce, or WooCommerce. They are especially useful when SEO must be coordinated with development or a migration.

WebFX

WebFX is a large full-service agency with a serious B2B and eCommerce portfolio. Their 750-person team covers SEO, AI visibility, content, paid media, CRO, web design, and analytics. They also use RevenueCloudFX to connect campaigns with leads and revenue.

WebFX is not a narrow B2B eCommerce specialist, but their scale and industrial client experience make them relevant here.

Best match: Mid-market and enterprise B2B eCommerce companies that need SEO and multi-channel execution
Core work: eCommerce SEO, technical SEO, AI search optimization, content, paid media, CRO, and web design
Working style: Dedicated account management backed by a large specialist team
Pricing: eCommerce SEO plans range from $2,500 to $7,500 per month; larger stores receive custom pricing
Strongest point: Connecting search performance with leads and revenue through RevenueCloudFX
Industries: Manufacturing, industrial products, automotive, healthcare, technology, and eCommerce

What Earned Them a Spot

WebFX’s reporting infrastructure and B2B results earned them a spot. The agency can connect search work with CRM data instead of stopping at rankings.

WebFX reports increasing AI and OmniSEO leads for Enabling Devices by 542%. Their case-study library also includes manufacturers, distributors, and eCommerce companies with results tied to leads or revenue.

Who We’d Recommend Them For

WebFX makes the most sense for mid-market and enterprise B2B eCommerce companies that need several marketing channels managed together. Their large team can support SEO, paid media, content, CRO, and web projects at the same time.

Companies wanting regular access to one senior strategist may prefer a smaller agency.

Coalition Technologies

Coalition Technologies combines B2B eCommerce marketing with design and development. Their team works with Shopify, BigCommerce, Magento, and custom storefronts. They also understand segmented pricing, Net 30 terms, minimum orders, account applications, and sales-rep quote workflows.

Best match: B2B eCommerce companies that need SEO alongside storefront design or development
Core work: eCommerce SEO, AI SEO, content, PPC, email marketing, web design, and development
Working style: Structured and execution-heavy with separate marketing and development specialists
Pricing: eCommerce SEO averages $2,500 per month; final pricing depends on the catalog and scope
Strongest point: Understanding the technical and operational requirements of B2B storefronts
Industries: Manufacturing, wholesale, industrial products, fashion, health, and home improvement

What Earned Them a Spot

Coalition Technologies made our shortlist because they understand the systems behind a B2B store. SEO can’t do much if customer pricing, catalog logic, checkout rules, or account workflows are badly built.

Their recent results also include a 766.9% year-over-year increase in AI search sessions for Asphalt Kingdom, a B2B supplier. That gives their AI SEO claims more substance than most.

Who We’d Recommend Them For

The clearest fit is B2B companies that need a storefront build or redesign alongside SEO. Coalition says they frequently serve businesses earning $1 million to $10 million annually, though they also handle larger accounts.

We would still challenge their public recommendation to redirect every 404 to the homepage. Irrelevant redirects can become soft 404s and waste crawl signals.

Searchbloom

Searchbloom is a search-focused agency whose technical depth maps directly onto B2B catalog problems. Their published material covers how platform behavior changes the work across Shopify, WooCommerce, BigCommerce, and Magento, which matters when a wholesale storefront runs segmented pricing or gated accounts on top of a standard platform. 

Their strategy prioritizes URLs by revenue potential, ranking difficulty, and implementation effort instead of pretending every product page deserves equal attention.

Best match: B2B eCommerce and wholesale stores with large catalogs or complex indexation problems
Core work: Technical eCommerce SEO, content, link acquisition, AEO, GEO, PPC, and development support
Working style: Custom and roadmap-driven through their ART and MERIT frameworks
Pricing: SEO services start at $3,000 per month; larger eCommerce programs receive custom pricing
Strongest point: Revenue-led URL prioritization and technical catalog optimization
Industries: B2B eCommerce, wholesale, apparel, automotive, home and garden, and specialty retail

What Earned Them a Spot

Searchbloom's technical thinking is visible before the sales call, and most of it is the thinking B2B catalogs need. They discuss canonicals, faceted navigation, parameterized URLs, segmented sitemaps, programmatic metadata, and Merchant Center feeds in practical terms.

Their published case studies include a 1,839% return on investment for an apparel wholesaler, which is closer to a distribution business than a consumer store.

Who We’d Recommend Them For

Large B2B catalogs with indexation problems are the clearest fit. Searchbloom is particularly relevant when filters create duplicate URLs or several product pages compete for the same commercial keyword.

The agency also suits wholesalers that need template-level optimization at scale. Companies planning deep ERP integrations or a complete storefront rebuild may want a development-heavy commerce agency instead.

Inflow

Inflow is an eCommerce-focused digital marketing agency with experience in SEO, paid media, and CRO. Their senior strategists work directly with clients instead of passing communication through account managers.

Best match: Established B2B eCommerce companies with active organic and paid campaigns
Core work: Technical SEO, content optimization, paid search, paid social, and CRO
Working style: Direct access to senior strategists with no traditional account managers
Pricing: Custom; Inflow says effective SEO services generally cost between $3,000 and $5,000 per month
Strongest point: Deep eCommerce experience combined with senior-level client access
Industries: eCommerce, retail, healthcare, travel, consumer products, and lead generation

What Earned Them a Spot

Inflow earned a spot for their depth in eCommerce, rather than a vague B2B claim. The agency publishes results that include a 126% increase in organic traffic and a 118% increase in organic revenue. Their direct-to-strategist model also separates them from larger account-management structures.

Who We’d Recommend Them For

We see the strongest fit with established B2B eCommerce companies that already have traffic and transaction data. Inflow can diagnose whether growth is blocked by crawl issues, weak category pages, paid media efficiency, or poor conversion paths.

Their team is less suitable for small stores seeking a low-cost package. They also don't position themselves as a B2B-only agency.

Straight North

Straight North has spent more than two decades running SEO for B2B companies. Their team covers national, eCommerce, enterprise, and local search.

For B2B sellers, the important point is their understanding of long research cycles, multiple decision-makers, quote requests, product downloads, and transactions that don't always end in a standard online checkout.

Best match: B2B manufacturers, distributors, wholesalers, and industrial suppliers
Core work: B2B SEO, GEO, eCommerce SEO, content, link acquisition, PPC, and web development
Working style: Full-service and campaign-led with an in-house specialist team
Pricing: SEO starts at $1,500 per month; most clients invest between $4,000 and $8,000 per month
Strongest point: Long-standing experience with B2B lead generation and eCommerce revenue
Industries: Manufacturing, industrial, logistics, professional services, healthcare, and technology

What Earned Them a Spot

Straight North belongs here because B2B is part of their operating history, not a new service page. Their team distinguishes product sales from demo requests, downloads, quotes, and other conversion points.

Who We’d Recommend Them For

The agency should appeal to manufacturers, distributors, and industrial suppliers that need lead generation and eCommerce revenue tracked together.

Straight North can also combine SEO with PPC or a website rebuild. Their broad service model suits companies that prefer one vendor.

Intero Digital

Intero Digital is a full-service agency with dedicated B2B and eCommerce capabilities. Their search team handles technical SEO, content, digital PR, link building, GEO, and structured data.

They also use the patented InteroBOT crawler to inspect large websites beyond the limits of standard desktop tools. The agency can connect organic search with paid media, Amazon, creative, and development under one strategy.

Best match: Mid-market and enterprise B2B eCommerce companies with complex websites
Core work: Technical SEO, eCommerce SEO, GEO, content, digital PR, link building, and paid media
Working style: Integrated specialist teams supported by proprietary search technology
Pricing: Custom, based on the scope
Strongest point: Technical eCommerce SEO supported by InteroBOT and multi-channel execution
Industries: B2B, manufacturing, SaaS, retail, healthcare, financial services, and professional services

What Earned Them a Spot

Intero Digital’s technical stack matches the demands of large eCommerce websites. They audit crawlability, canonicalization, redirect logic, schema, Core Web Vitals, and site hierarchy. Their B2B proof is also concrete.

The agency reports helping Sticker Mountain increase eCommerce sales by 305% and organic traffic by 3,907%, while monthly revenue rose from $6,000 to more than $50,000.

Who We’d Recommend Them For

We would put Intero Digital in front of mid-market and enterprise B2B eCommerce companies with complex catalogs or several acquisition channels. Their team can coordinate SEO, GEO, digital PR, paid media, Amazon, CRO, and development.

Smaller companies that need only a technical audit may find the agency too broad.

The Bottom Line

Our team spent a lot of time reviewing B2B eCommerce SEO agencies for this list. The agencies included here stood out for different reasons, and each one deserves consideration.

However, we don’t think there is one agency that will suit every B2B eCommerce company. Some businesses need serious technical SEO support. Others need content, development, CRO, or paid media alongside SEO. Budget and internal resources also matter.

Use this list to narrow down your options. Then speak with the agencies, ask specific questions, and review their proposals carefully. The right partner should understand your website, customers, and sales process before recommending a strategy.
