Best Shopify SEO agencies in 2026: 12 ranked

One of the few Shopify agencies that will work month-to-month, which matters when the last one locked you into twelve months and sent a PDF each quarter. Strong on collection-page strategy, internal linking and the on-page fundamentals Shopify themes get wrong by default. Content volume is moderate, and they serve local clients alongside stores, so the Shopify specialisation is real but not exclusive.

A large Shopify partner with design and development in-house, which removes the usual standoff where the SEO team recommends a template change and the dev agency quotes six weeks. Good for Plus merchants with real theme debt. Large agencies spread attention, and top-tier retainers here reach five figures a month.

Engineering-led Shopify Plus support where SEO sits beside ongoing platform work — Liquid, rendering, speed, collection templates, app conflicts. If your rankings are being held back by the theme rather than the content, this is the right kind of vendor. The writing side is minimal, so plan to source content elsewhere.

Not Shopify-exclusive, but nobody on this list has been doing store SEO longer. That experience pays off on catalogues large enough that Shopify's faceted filters start generating thousands of near-duplicate URLs. They are also doing real work on getting product and category pages into AI answers. Agency pricing, headcount-limited output.

Large, heavily reviewed, and a safe pick for a merchant who wants to verify a vendor before signing. Competent on Shopify basics: product schema, collection titles, site speed, paid search alongside organic. Less strong on the content programmes that win the category and guide terms sitting above your product pages.

A big full-service agency with a long roster of Shopify accounts and reporting a non-marketer can read. Reasonable for a mid-size store that wants steady competence. The playbook is standardised, so you get a solid version of the same programme every other merchant gets rather than something shaped to your catalogue.

Platform-agnostic but very comfortable on Shopify, and unusual in running SEO, paid and conversion work as a single program. That matters on a store where lifting conversion 0.3% beats another 5,000 sessions. Senior people stay on the account. Content output is deliberately small and pricing is mid-to-upper market.

A well-regarded agency covering SEO, paid, email and social for DTC brands. Convenient when you want one vendor across every channel a Shopify brand runs. Shopify SEO specifically is a slice of a much wider offer, and the pricing reflects the full package rather than the organic work alone.

Shopify stores lose category terms to publishers and marketplaces with far stronger domains, and links are usually why. Siege earns them properly, with original research and designed assets rather than outreach spam. It is expensive per placement and Shopify is not a specialisation.

Aimed at smaller merchants who cannot justify a five-figure retainer, with straightforward keyword, on-page and link work and quick replies. Honest about what a small budget buys. What it buys is incremental: expect steady improvement rather than a change in how much of your catalogue is covered.

Best known for ecommerce web design, with SEO offered alongside the build. A fair choice if the real problem is that your storefront looks dated and converts badly, and organic is the second priority. As an SEO-first pick, content output and AI-search work are limited.
