Enterprise ecommerce SEO becomes complicated when a store grows beyond a manageable set of categories and product pages. Large catalogs introduce faceted navigation, product variants, discontinued inventory, duplicate URLs, international storefronts, and technical decisions that can affect thousands of pages at once. Platform limitations add another layer because Shopify, Magento, Salesforce Commerce Cloud, custom frameworks, and headless setups create very different search problems.
The agency handling this work therefore needs to understand both commercial search demand and the infrastructure carrying the catalog. The six companies below take different approaches to ecommerce SEO, ranging from technical architecture and developer guidance to full-service search, content, analytics, and shopping support.
1. Organic Hackers
Organic Hackers approaches ecommerce SEO from the technical side, with an emphasis on large websites where architecture and implementation directly affect organic revenue. The consultancy works closely with development teams instead of treating SEO recommendations as tasks that end once an audit has been delivered. Its current positioning includes website architecture optimization, technical implementation verification, migrations, shopping-first strategy, generative AI search, and direct communication with technical teams.
That model is especially relevant to stores with large catalogs, where filtering, crawl waste, rendering problems, or weak indexation can quietly affect huge numbers of URLs. The company also works with AI-search infrastructure, giving ecommerce teams a way to think about conventional organic visibility and newer product discovery channels together.
For a large store, the value of this approach sits in the technical details that are easy to miss when teams concentrate only on rankings and content. Organic Hackers can support several areas tied directly to ecommerce scale:
- Catalog architecture: Reviewing how product, category, filter, and market structures affect crawling and discovery;
- Indexation control: Identifying wasted crawl activity, unnecessary URL generation, and sections that fail to reach the index efficiently;
- Developer guidance: Translating SEO problems into specific technical tasks for internal or agency engineering teams;
- Implementation review: Checking whether recommended fixes were deployed correctly and whether they produced the intended technical result;
- AI search readiness: Improving structured information, retrieval paths, and monitoring for platforms beyond conventional Google results.
This is a relatively hands-on technical model rather than a service built around producing large volumes of ecommerce copy. It gives internal teams direction while leaving execution closely connected to the developers who already understand the platform.
Where It Fits Best
Organic Hackers makes the most sense for established retailers with large catalogs and access to engineering resources. Companies expecting one agency to write every product description, run paid media, and execute the entire marketing program will probably need a broader partner alongside it.
2. Amsive
Amsive treats ecommerce SEO as part of a wider search and performance marketing operation rather than a standalone technical exercise. Its ecommerce service combines site audits, technical optimization, keyword research, category and product content, SERP analysis, and reporting. Technical reviews can cover architecture, Core Web Vitals, structured data, crawling, and indexation, while the broader agency also has access to development, UX, analytics, media, and creative teams.
This gives retailers more room to connect organic search work with the rest of their acquisition strategy. Amsive has also expanded into AEO and LLM optimization, so its search offering now covers traditional ecommerce discovery alongside AI-generated answers.
The ecommerce service spans both structural problems and the pages customers actually use when researching products. Relevant parts of the offer include:
- Site auditing: Reviewing architecture, schema, performance, and the health of important transactional pages;
- Product and category optimization: Improving the search value of commercial pages rather than relying entirely on informational content;
- Keyword research: Finding transactional demand and supporting topics around a store’s catalog;
- Technical SEO: Addressing crawling, indexing, JavaScript rendering, internationalization, and Core Web Vitals;
- AI discovery: Extending optimization into AI Overviews, ChatGPT, Perplexity, and other answer-driven surfaces.
Amsive offers more than a narrow ecommerce SEO engagement because clients can bring in other internal disciplines when the project demands them. That breadth can reduce the number of separate agencies a retailer needs to coordinate.
A Good Match For
This setup can work well for ecommerce brands that want SEO connected with development, analytics, content, and other marketing channels. It is particularly practical when organic search is only one part of a larger customer acquisition program.
3. Greenlane Marketing
Greenlane Marketing has worked with ecommerce businesses for years and takes a broader retail-search approach that combines SEO with paid media, analytics, shopping feeds, and marketplace support. The agency works across platforms including Shopify, Magento, BigCommerce, WooCommerce, and Amazon Marketplace rather than building its offer around a single ecommerce system. Its organic work combines technical SEO, content marketing, user experience, and search strategy, while its commerce services also extend into product feeds and shopping visibility.
Greenlane now incorporates AI-search considerations into its ecommerce positioning, including visibility in LLMs and Google AI Overviews. This makes the agency relevant to retailers that care about the entire search-to-purchase journey rather than only technical fixes behind the scenes.
Its ecommerce work reaches several areas that sit close to revenue and product discovery. The service mix can cover:
- Technical SEO improvements: Resolving structural and onsite issues that restrict organic performance;
- Commerce platform support: Working across major store systems without tying the strategy to one technology;
- Shopping feed optimization: Improving product data used across Google and other commerce platforms;
- Marketplace visibility: Supporting product discovery across environments such as Amazon and Walmart;
- Analytics and reporting: Connecting search and shopping activity with the behavior that eventually leads to purchases.
Greenlane differs from a pure technical consultancy because it can stay involved across several stages of ecommerce acquisition. That may appeal to retailers that want one team contributing to organic, paid, shopping, and measurement work.
Who Is Likely to Benefit Most
Retailers with several digital sales channels are the clearest fit for this model. A business selling through its own store, Google Shopping, and external marketplaces may get more value from the wider commerce perspective than from a strictly technical SEO engagement.
4. Screaming Frog
Screaming Frog combines technical SEO consultancy with the crawling technology that made its name familiar to search teams around the world. Its agency specifically states that it works with large and complex ecommerce websites across multiple languages and locations. The consulting side covers technical auditing, architecture, migrations, market research, international SEO, and other search work, while the SEO Spider provides a powerful way to inspect large URL inventories.
This becomes useful in ecommerce because filters, attributes, category structures, pagination, and product variations can generate enormous crawl spaces that are difficult to inspect manually. The agency’s role is not simply to run the crawler but to interpret the resulting data and turn it into prioritized recommendations.
Large stores can generate far more technical data than an internal team can realistically review page by page. Screaming Frog’s work is particularly relevant in areas such as:
- Large-scale crawling: Inspecting substantial product and category inventories for technical inconsistencies;
- Architecture analysis: Reviewing crawl depth, internal linking, navigation, and relationships between commercial sections;
- Migration planning: Protecting organic signals during domain, platform, or structural changes;
- International SEO: Investigating multilingual and multi-location ecommerce setups;
- Technical prioritization: Separating issues with meaningful organic impact from low-value warnings in a large audit.
Its combination of consulting and crawling expertise is useful when the first challenge is understanding exactly what is happening across a very large store. Companies can also involve the wider agency when the findings need to feed into a broader organic-search plan.
Most Useful For
Screaming Frog is a sensible option for ecommerce teams that need a rigorous technical audit or are preparing for a complicated migration. It can also suit internal SEO teams that already know their commercial priorities but need deeper crawl analysis to expose structural problems.
5. SALT.agency
SALT.agency has a dedicated ecommerce SEO practice covering both enterprise retailers and growing commerce brands. Its current service model starts with technical analysis but extends into structured data, international SEO, editorial strategy, Merchant Center, programmatic SEO, and AI visibility. The agency also emphasizes RevOps, connecting search work with measurable commercial outcomes instead of treating traffic as the only goal.
For large retailers, SALT works directly with development and IT teams so technical recommendations can remain connected to sprint planning and implementation. Its experience across ecommerce environments also includes Salesforce Commerce Cloud, where catalog-driven URLs, faceted navigation, and international variations can create significant technical debt.
This creates a service mix that stretches from the technical foundation of the store to the systems responsible for product discovery. Areas worth noting include:
- Technical ecommerce SEO: Improving crawling, indexation, site speed, structured data, and large-site architecture;
- Programmatic SEO: Scaling optimization across extensive catalogs without treating every page as an isolated manual project;
- International search: Managing language, country, and market signals for stores operating across regions;
- Merchant Center support: Improving feeds and product information used in shopping experiences;
- Revenue-oriented measurement: Connecting organic search initiatives with commercial performance rather than reporting visibility alone.
SALT therefore sits between specialist technical consultancy and broader ecommerce search strategy. Its range is useful when product architecture, development, international expansion, and commercial reporting all need to remain connected.
The Right Environment
Enterprise retailers with complicated platforms or multi-market storefronts are likely to get the clearest value from this model. It also suits teams that want SEO specialists involved directly with developers while still having access to wider ecommerce strategy.
6. Onely
Onely approaches ecommerce visibility through technical SEO and, increasingly, AI search rather than through a traditional full-service retail marketing model. The agency has deep experience with JavaScript, rendering, crawling, and indexing problems that can become serious when thousands of product or category pages depend on dynamic front-end technology.
Its JavaScript SEO service includes audits, SPA optimization, performance work, prioritized recommendations, and cooperation with development teams during implementation. More recent ecommerce research from Onely also examines how structured product information, crawlable pages, feeds, reviews, and consistent data influence visibility in ChatGPT and other AI-driven search experiences.
That combination makes the company particularly relevant to technically sophisticated stores where search visibility problems begin at the infrastructure level.
The agency’s ecommerce relevance is strongest where modern front ends or complicated indexation behavior create uncertainty. Its work can address several technical pressure points:
- JavaScript rendering: Checking whether important product and category information is actually available to crawlers;
- Indexation analysis: Finding structural reasons why valuable ecommerce URLs remain outside search indexes;
- SPA optimization: Resolving problems created by React, Vue, Angular, and other dynamic application structures;
- Developer collaboration: Moving from diagnosis into recommendations that engineering teams can implement;
- AI-search visibility: Examining how product information is retrieved, interpreted, and represented by generative search systems.
Onely does not need to resemble a conventional ecommerce marketing agency for this approach to be useful. Its role is strongest when the problem sits underneath the marketing layer and requires detailed technical investigation before growth work can move forward.
When This Approach Makes Sense
Onely is a logical choice for retailers running JavaScript-heavy storefronts or struggling with persistent crawl, rendering, and indexation issues. It may be less suitable for a company primarily searching for paid shopping management, large-scale copy production, or a complete ecommerce marketing department.
Final Thoughts
The strongest ecommerce SEO partner depends on what is actually preventing the store from growing rather than on how many services appear in an agency’s navigation menu. Organic Hackers and Onely lean heavily toward technical infrastructure, while Amsive and Greenlane provide wider marketing support around search and commerce. Screaming Frog brings deep crawling and audit experience, whereas SALT.agency combines technical ecommerce work with international, programmatic, Merchant Center, and revenue-focused strategy.
Catalog size, platform complexity, development resources, international reach, and the need for support outside SEO should all shape the shortlist. A retailer that identifies those constraints before contacting agencies will have a much easier time separating useful specialization from services it does not actually need.
