Shopify makes it easy to launch a store and surprisingly easy to cap its organic growth. Duplicate product URLs, thin collection pages, app bloat slowing everything down, filtered pages Google can't make sense of. None of it is fatal. All of it needs someone who knows the platform.
Most "best Shopify SEO agency" lists are written by agencies who rank themselves first. So are we. The methodology is below, we've said who we left out and why, and every other agency here is described the way they describe themselves.
The 10 best Shopify SEO agencies at a glance
| Agency | Based in | Best for | Builds Shopify sites? | Built for AI search (AEO/GEO) |
|---|---|---|---|---|
| 1. Nomada Digital | York, UK | Brands that want to rank on Google and be named in AI shopping answers | Yes - builds and improves stores with AI-assisted development | Yes - core to the model |
| 2. ClickSlice | London | Ecommerce brands wanting a pure SEO specialist | Some web design | Yes |
| 3. Paramount Digital | St Helens / Liverpool | Mid-market stores wanting SEO and dev under one roof | Yes | Partially |

Nomada Digital publishes this list. We've explained the reasoning below rather than pretending to be a neutral party.
How we built this list
Five criteria got an agency onto it.
1. A published Shopify SEO offer - a dedicated Shopify SEO service, Shopify Partner status, or named Shopify brand work.
2. A UK base, confirmed on the agency's own site.
3. Evidence of commercial outcomes - organic revenue, conversions, sales - not just traffic.
4. Readiness for AI search, because shoppers now ask ChatGPT and Google's AI Mode which brand to buy.
5. Clarity on whether the agency builds stores, ranks them, or both.
Who we left out: US-headquartered agencies, freelancers, directory listings, and agencies whose Shopify SEO offer we couldn't confirm from their own site.
We're an SEO and AI visibility agency ourselves, so treat our own entry with the scepticism it deserves. There are no paid placements, affiliate arrangements or reciprocal link deals on this page.
Why Shopify SEO is its own job
General ecommerce SEO applies, but Shopify adds its own quirks.
| What changes | Generic SEO approach | Shopify specialist approach |
|---|---|---|
| URLs | Assumes full control | Works around fixed /products/ and /collections/ paths |
| Duplicate content | Standard canonical fixes | Handles collection-scoped product URLs and filter pages |
| Speed | Image compression | Audits apps and theme code that load on every page |
| Collection pages | Treated as listings | Built as ranking pages with real content |
| International | Separate sites | Shopify Markets, subfolders and hreflang |
| AI search | Ignored | Product data and third-party mentions shaped for AI shopping answers |
The biggest wins on most Shopify stores come from collection pages. They match how people search ("men's waterproof ski jackets", not a product name), and they're usually the thinnest pages on the site.
The 10 best Shopify SEO agencies
1. Nomada Digital
Based in: York, UK. Best for: brands that want to rank on Google and be named when shoppers ask AI what to buy.
Nomada is an SEO and AI visibility agency that also builds and develops Shopify stores. On Shopify we focus on collection and product page rankings, technical fixes the platform makes awkward, and getting brands named in AI shopping answers through placements on the pages those answers cite. Imogen Pope London, a designer lampshade brand, grew organic traffic 76% year on year and became a go-to name for luxury lampshades in the UK. See the case study. Our founder built the agency after running his own ecommerce brand.
Worth knowing: we build and develop Shopify stores as well as ranking them, using an AI-assisted development process, so new pages, SEO fixes and theme changes ship in days rather than waiting in a developer's queue. Where a client already has a development agency, we work to their standards and through their review process. For a very large Shopify Plus replatform, the bigger build teams below are also worth a call.
2. ClickSlice
Based in: Shoreditch, London. Best for: DTC and ecommerce brands wanting a pure SEO specialist rather than a build agency.
ClickSlice has a dedicated Shopify SEO service covering audits, technical SEO, site speed, collection page optimisation, content and monthly link building, with an AEO offer for Shopify stores across ChatGPT, Gemini and Perplexity. Founded in 2016.
Worth knowing: SEO-first, so you'll need a separate developer for bigger theme work.
3. Paramount Digital
Based in: Rainford, St Helens, with a Liverpool office. Best for: mid-market Shopify stores wanting SEO and development from one team outside London.
Paramount describes itself as one of the few specialist Shopify SEO agencies in the UK, with a dedicated Shopify department covering technical fixes, collection and product optimisation, copy, link building and international SEO. Published Shopify work includes Kendal Tools & Machinery (+43% organic revenue) and a Shopify 2.0 upgrade for Charles & Ivy.
Worth knowing: a Shopify partner that builds as well as ranks.
4. Eastside Co
Based in: London, with New York and Dubai offices. Best for: Shopify Plus brands wanting SEO from a large, partner-tier build agency.
Eastside Co says it was among the first three UK agencies accredited as a Shopify Plus partner and has built over 500 Shopify stores. Its Shopify SEO service covers technical issues, collection and product optimisation and authority building, with a dedicated AI search and generative engine optimisation offer.
Worth knowing: build-led agency, so SEO sits alongside a much larger development practice.
5. Swanky
Based in: Exeter, with offices in Australia and France. Best for: Shopify Plus brands, migrations and cross-border stores.
Swanky has been working with Shopify since 2010, is a Shopify Plus partner, and runs a Shopify SEO service covering content, technical SEO, link building, international SEO and GEO. Logos on its SEO page include Boucleme, DockATot and Forthglade.
Worth knowing: strongest when SEO is part of a migration or Plus build.
6. blubolt
Based in: Bath. Best for: established Shopify brands migrating or expanding internationally.
blubolt was founded in Bath in 2006 and offers SEO and GEO for established Shopify and Shopify Plus brands - technical SEO, content, product and collection optimisation, international SEO and migrations, reported against organic revenue. Published work includes Green People (+100% organic sessions).
Worth knowing: aimed at established brands rather than early-stage stores.
7. Charle
Based in: London, with Manchester and New York offices. Best for: Shopify Plus brands wanting design, CRO and SEO from one team.
Charle offers SEO for Shopify and Shopify Plus - category research, technical audits, collection and product optimisation, structured data, digital PR and international SEO via Shopify Markets - plus an AI visibility service. Clients shown include Cambridge Satchel, Candy Kittens and RNLI.
Worth knowing: a design and CRO agency first, with SEO as a strong second discipline.
8. Underwaterpistol
Based in: London. Best for: Shopify Plus brands that want SEO attached to a replatform or redesign.
Underwaterpistol is a Shopify Plus partner with over 20 years in ecommerce. Its SEO is audit-led - competitors, content, technical - followed by strategy, copywriting and reporting. Shopify work includes Ooni, Patou and Omaze.
Worth knowing: SEO is one service within a build agency.
9. Siruss
Based in: Shrewsbury. Best for: SMEs wanting a regional, retainer-style Shopify SEO provider.
Siruss runs ongoing Shopify SEO, technical audits, link building, content, Core Web Vitals work and analytics setup, and has worked with Shopify since 2016. Named Shopify clients include Candy Obsession and The Bed Supermarket.
Worth knowing: a smaller regional team, which suits SMEs that want a direct relationship.
10. Herdl
Based in: Ashby de la Zouch, Leicestershire, with Nottingham and London offices. Best for: SMEs wanting a Shopify partner for SEO and web.
Herdl offers Shopify SEO for stores of all sizes, UK and international, alongside Shopify design and development, and offers a free audit.
Worth knowing: ask for Shopify SEO case studies on the call.
Also worth a look: Found (London) has a dedicated Shopify SEO offer, Search Hog (Cornwall) publishes Shopify SEO from £990 + VAT a month, and Fourmeta and Magic42 are strong Shopify build agencies that handle SEO through migrations.
What a Shopify SEO agency costs in the UK
Few Shopify SEO agencies publish prices. These are UK market ranges, not quotes from any agency on this page.
| Engagement type | Typical monthly range | Best suited to | What's usually included |
|---|---|---|---|
| Audit or migration support | £1,500-£6,000 (one-off) | Stores replatforming or fixing a decline | Technical audit, redirect map, roadmap |
| Small specialist or regional agency | £1,000-£3,000 | Smaller stores | Technical fixes, collection pages, some content |
| Specialist SEO agency | £3,000-£7,000 | Growing DTC brands | Full SEO, content, links, reporting to revenue |
| Shopify Plus build agency with SEO | £5,000-£12,000+ | Plus brands with dev needs | SEO plus development, CRO and design |
Ask whether link building and digital PR are included, and whether theme changes are done by the SEO team or billed as development.
The gap almost every agency on this list still has
Shoppers increasingly ask AI what to buy. "Best waterproof ski jacket under £300", "best electrolyte drink for running", "luxury lampshade brands UK" - and ChatGPT or Google's AI Mode answers with a handful of brands and the pages it got them from.
Those pages are mostly third-party: gift guides, "best of" lists, review sites, editorial roundups. If your brand isn't on them, you're not in the answer, however well your collection pages rank.
Try the test. Ask ChatGPT and Google for the best product in your category three different ways, and note which brands are named and which pages are cited. That list of cited pages is your outreach plan.
Several agencies here are building AI search capability. Ask any of them what share of relevant AI shopping answers currently name your brand, and how they'd move it.
How to shortlist a Shopify SEO agency
| What to check | Why it matters | What a good answer looks like |
|---|---|---|
| Shopify-specific case studies | Shopify has its own technical limits | Named stores with organic revenue results |
| Collection page plan | The biggest ranking opportunity on most stores | A clear plan for content and internal links |
| Who touches the theme | SEO fixes often need code | A named developer, or a clear handover to yours |
| App and speed audit | Apps quietly slow every page | A review of what loads and why |
| AI search measurement | Shoppers ask AI before they search | A tracked share of AI answers naming you |
| Contract terms | Long lock-ins protect the agency | Rolling or 3-6 month terms |
The honest caveat
We rank ourselves first on a list we publish. Weight that accordingly.
We build and develop Shopify stores as well as ranking them, and we're B2B-first - ecommerce is a smaller part of what we do. If your priority is a very large Shopify Plus replatform with a big in-house team, Swanky, Eastside Co, blubolt or Charle are also worth a call, and we'd rather tell you that now.
Where we fit best is a store that needs to be built or improved and found at the same time: ranking on Google and named in AI answers, with the development done by the same team, or alongside your existing developer if you have one.
Frequently asked questions
Is Shopify good for SEO?
Yes, with caveats. Shopify handles the basics well - hosting, SSL, sitemaps, mobile themes - but restricts URL structures, creates duplicate product URLs through collections, and can slow down as apps pile up. All of it is fixable with the right setup.
How much does Shopify SEO cost in the UK?
Most UK Shopify stores spend £1,000-£7,000 a month on SEO, depending on size and competition. Shopify Plus brands using build agencies often spend more, because SEO is bundled with development.
Do I need a Shopify Partner for SEO?
Not necessarily. Partner status shows an agency builds on Shopify, which helps for technical fixes, but plenty of strong SEO agencies work alongside your existing developer. What matters is Shopify-specific results.
How long does Shopify SEO take?
Technical fixes and collection page improvements can move rankings within two to three months. Competitive category terms usually take six months or more, depending on links and competition.
What's the difference between a Shopify SEO agency and a Shopify agency?
A Shopify agency mainly designs and builds stores. A Shopify SEO agency mainly grows organic traffic and revenue. Some do both. If you're happy with your store, hire for SEO; if you're replatforming, a build agency with SEO capability makes sense.
The takeaway
The question isn't "who's the best Shopify SEO agency?" It's "do we need a build, or do we need to be found?"
If your store needs rebuilding, start with a build agency that does SEO. If your store is fine but invisible - on Google, or in AI shopping answers - hire for SEO and visibility.
