Best Ecommerce SEO Agencies

Ecommerce SEO is a narrower specialism than most people expect. Category and collection pages, faceted navigation, duplicate content across thousands of near-identical product variants, and non-branded organic growth all make it a genuinely different discipline from general SEO. Not every agency that lists “ecommerce” as a service on their website has actually built a process around it, plenty are web design or full-service generalists who build Shopify stores and treat SEO as an afterthought.

Here’s an honest, researched look at eight UK agencies that have. If you’re not sure an ecommerce SEO agency is even the right call versus a solo consultant, the decision framework below is worth reading first.

1. NOVOS #

London, UK. Founded 2019, employee-owned, 40+ SEO professionals.

NOVOS was built exclusively around ecommerce from day one. In six years they’ve supported 200+ ecommerce brands, including Pooch & Mutt, Osprey, Antler, Vitabiotics, Bloom & Wild, and Made.com, and claim over £50M in organic growth generated for clients across the UK, US, and Europe. Their award haul is substantial too: Global eCommerce Agency of the Year 2023, plus recognition at the UK Search Awards, Global Search Awards, and The Drum Awards.

Genuinely good at: non-branded organic growth on category and collection pages specifically, one of the genuinely harder problems in ecommerce SEO, backed by real, named client results rather than vague claims.

Worth weighing up: a 200+ brand client roster built over six years suggests real scale and process, but also real competition for attention. Worth asking directly how many accounts your strategist is actually running at once.

2. Eastside Co #

London, UK, with offices in Birmingham, New York, and Hamburg. Founded 2012, 80-strong team.

Eastside Co is a Shopify Plus specialist covering design, development, SEO, PPC, paid social, CRO, and email under one roof, the largest team on this list by a clear margin. They’ve worked with recognisable names like Carex, Wild Deodorant, Absolute Collagen, and Chelsea FC.

Genuinely good at: scale and breadth. If you want SEO handled alongside a full Shopify Plus build or replatform, rather than as a bolt-on to work someone else did, this is a legitimate one-stop option.

Worth weighing up: SEO is one discipline among several for an 80-person, multi-office team built primarily around Shopify Plus design and development. Worth confirming SEO gets a dedicated specialist, rather than a generalist splitting time across design, dev, and marketing work.

3. MadeByShape #

Atherton, near Manchester. Founded 2010, team of 16.

MadeByShape is a smaller, boutique web design and branding agency with organic SEO as one of its core services alongside Shopify builds, working largely with fashion and lifestyle ecommerce brands. Fifteen years running as a small, stable team is a real signal in an industry where agencies come and go.

Genuinely good at: a genuinely collaborative, small-team relationship, no layers between you and the people doing the work, with real design sensibility for fashion and lifestyle brands specifically.

Worth weighing up: SEO sits alongside web design and branding rather than being the agency’s core reason for existing. Worth asking for ecommerce SEO results specifically, separate from design portfolio work.

4. Futur Media #

Cardiff, Wales.

Futur Media is a Shopify-first agency covering design, custom development, SEO-safe migrations, CRO, and SEO, with most work happening remotely and, notably, direct access to the founder rather than an account manager layer.

Genuinely good at: SEO-safe Shopify migrations specifically, a real, common failure point where ecommerce sites lose rankings during a replatform, and direct founder access by design rather than as an exception.

Worth weighing up: less independently published detail on team size, founding date, and named ecommerce SEO case studies than the other names here. Worth asking directly for proof of organic results specifically.

5. Reboot Online #

London, with a remote UK team. Founded 2012, 70+ ecommerce SEO specialists (reported).

Reboot Online has worked with ecommerce brands including Uswitch, Mattress Online, and Clear It Waste over more than a decade in search marketing. Digital PR and content sit alongside SEO as part of the same offering rather than a separate add-on, and the agency picked up wins at the Global Search Awards and UK Search Awards in 2025.

Genuinely good at: a long-running, dedicated ecommerce specialism with digital PR built in, useful if link building is a gap in your current setup rather than something you want to coordinate separately.

Worth weighing up: reported team size varies a lot by source, from under 50 to 70+. Worth confirming directly how many people are actually working ecommerce accounts specifically, rather than the headline company-wide figure.

6. eComOne #

Lincoln. Rebranded to eComOne in 2018, team of around 20.

eComOne works exclusively with ecommerce brands, with a stated focus on retailers in the £1M–£30M revenue range, larger than most names on this list. Named clients include Maplin, Splash About, Bushwear, and Safelincs, and the agency holds Google Premier Partner and Shopify Plus Partner status. In 2025 it brought on Stephen Kenwright, former co-founder and chief commercial officer of Rise at Seven, as a non-executive director.

Genuinely good at: working with larger, more established ecommerce brands specifically, rather than being a generalist agency that happens to also do ecommerce.

Worth weighing up: the revenue range they focus on suggests they may fit a bigger store better than a smaller, newer one. Worth asking directly whether a store below that range gets the same level of attention.

7. Opace #

Birmingham. Founded 2008, reported team size ranges from around 8 to 22 depending on the source.

Opace has specialised in ecommerce SEO for over 15 years, working primarily with WooCommerce and Magento stores, and reports having delivered 500+ projects across its history.

Genuinely good at: specific platform depth on WooCommerce and Magento, two platforms that get less dedicated agency attention than Shopify.

Worth weighing up: I couldn’t find named client case studies independent of the agency’s own site. Worth asking directly for specific, verifiable ecommerce results rather than a project count.

8. Blue Array #

Basingstoke, with offices in Reading and London. Founded 2015, 25+ SEO specialists.

Blue Array describes itself as the UK’s largest pure-play SEO agency, meaning it doesn’t run PPC, social, or other broader digital marketing channels alongside SEO. Clients include Zoopla, Pret, Boden, and Yell, with a published case study showing +119% organic traffic growth for Pepper Money. Ecommerce and retail are among the industries it serves, rather than its sole focus.

Genuinely good at: SEO depth without the distraction of running other channels alongside it, plus a verifiable, named case study with a real number attached.

Worth weighing up: ecommerce is one of several industries it serves rather than an exclusive specialism, closer to Eastside Co’s position on this list than to NOVOS or eComOne.
