Quick answer: the best Shopify SEO agencies
The best Shopify SEO provider depends on whether you need the storefront built right or an ongoing search program run. For a custom Shopify storefront with SEO built into the code from day one, Liquid Lemon is our pick: a Shopify / Shopify Plus design + development studio with a fixed $9,500 build, or from $12,500 on Shopify Plus, delivered in a 30-day sprint. For an ongoing, retainer-style SEO program, Searchbloom, OuterBox, Inflow, Coalition Technologies, and Siege Media each fit different needs across technical SEO, migrations, content, and answer-engine work. eSEOspace rounds out the list for hands-on Shopify SEO consulting.
Shopify SEO usually involves two overlapping workstreams, and the right provider depends on which one your store needs. One is the storefront's technical foundation: clean code, fast pages, correct structure and schema, so the site can rank at all. The other is the ongoing program: keyword strategy, content, internal links, and now answer-engine optimization aimed at improving how a brand shows up in ChatGPT, Claude, and Perplexity. Some brands need one, some need both.
How we picked these agencies
We compared providers on four things: Shopify and ecommerce specialization, publicly documented services, evidence of relevant client or case-study work, and the type of engagement offered. The "best for" labels describe the use case each provider fits based on its published services, not a measured performance ranking. Liquid Lemon is our own studio, so we place it against a clear, disclosed criterion, SEO built into a custom storefront, rather than presenting this as an independent ranking of agency results.
Two kinds of Shopify SEO help
Knowing the split makes the shortlist obvious.
SEO-ready storefront build
A studio that handles technical SEO in the build: fast, clean, well-structured pages with proper headings, metadata, and schema, plus content structured to be quotable by AI answer engines. Best when you are redesigning or launching and want the foundation right from day one. Ask what SEO and content deliverables are included in the scope. This is where Liquid Lemon sits.
Ongoing SEO program
A retainer agency that runs keyword strategy, on-page and technical fixes, content, and link building month over month. Best when the storefront is solid and you need sustained growth in rankings and traffic.
Answer-engine optimization (AEO / GEO)
A newer specialty aimed at improving how a brand is represented in AI-generated answers. Increasingly bundled into SEO programs, but worth asking about specifically, because the tactics differ from classic ranking work and the terminology varies by provider. We cover the mechanics in our guide to answer engine optimization for Shopify.

The best Shopify SEO agencies in 2026
1. Liquid Lemon: best for SEO built into a custom Shopify storefront
Liquid Lemon is a Shopify / Shopify Plus design + development studio for DTC brands that handles the technical SEO foundation directly in the storefront: clean, fast, well-structured code, correct metadata and schema, and content structured to be quotable by AI search. Pricing is fixed and public at $9,500 for a custom Shopify build and from $12,500 on Shopify Plus, with more complex Plus builds quoted higher, each delivered in a 30-day sprint. Its published work includes custom Shopify builds for DTC brands like Gymshark, Olipop, and Hero Cosmetics, including a public Gymshark Shopify redesign case study: it was the team behind Olipop's subscription experience and Hero Cosmetics' DTC Shopify launch partner, with food and beverage CPG experience including Poppi. Best for: brands launching or redesigning who want SEO handled in the build, on a fixed scope. Tradeoff: this is a fixed-scope build studio, not a month-to-month SEO retainer shop, so pair it with an ongoing program if you need sustained content and link work after launch.
2. Searchbloom: best for ecommerce SEO alongside paid search
Searchbloom is an SEO and PPC agency with dedicated Shopify and ecommerce SEO services, including technical audits, content, site architecture, and link building. Best for: brands comparing an ecommerce SEO program with related paid search from one provider. Tradeoff: a multi-channel search agency running both SEO and PPC rather than a Shopify-only design and development shop, so confirm Shopify depth for your category.
3. OuterBox: best for Shopify migrations and technical SEO
OuterBox offers Shopify SEO, technical optimization, migration support, and related ecommerce services, with a public case-study library covering site structure, schema, and organic performance. Best for: larger Shopify catalogs that need migration SEO, site structure, and product and collection optimization. Tradeoff: a bigger agency footprint than a boutique studio.
4. Inflow: best for ecommerce SEO paired with conversion
Inflow is an ecommerce SEO agency that pairs organic-growth strategy with conversion-focused work. Best for: DTC brands that want SEO joined to on-site conversion rather than rankings alone. Tradeoff: confirm the proposed team structure, capacity, and scope for larger programs.
5. Coalition Technologies: best for integrated SEO, paid, and development
Coalition Technologies is a full-service agency spanning SEO, paid media, design, and development, with a public Shopify services offering; the Shopify Partner directory describes its team as more than 300 people. Best for: brands that want one larger team running search alongside paid and development. Tradeoff: a broad full-service model rather than a Shopify-only specialist.
6. Siege Media: best for content-led SEO and AI-search visibility
Siege Media is a content marketing and digital-PR agency that has documented work on answer-engine visibility, including brand citations in AI Overviews and large language models. Best for: brands whose growth lever is content and visibility in AI answers. Tradeoff: content-first, so it pairs best with a solid technical foundation already in place.
7. eSEOspace: best for Shopify SEO with GEO and AEO services
eSEOspace provides Shopify and ecommerce SEO, including technical SEO, structured data, conversion optimization, and GEO and AEO services, with a published Shopify SEO framework covering both technical and strategic work. Best for: brands wanting a search-focused provider that also addresses AI visibility. Tradeoff: confirm scope and capacity directly for your brand's needs.
How to choose the right Shopify SEO agency
Work through four questions. First, is the problem the storefront foundation, or an ongoing program? A store with real technical or structural problems should have those fixed, in a rebuild or alongside ongoing work, before expecting a retainer to pay off. Second, do you specifically need answer-engine visibility, and can the provider show how it approaches AI answers, not just Google rankings? Third, is the scope and price fixed and clear, or open-ended? Fourth, has the team done real Shopify work in your category? Match those answers to the categories above and the shortlist gets short fast.
