Last updated: 20 October 2026
We’re eComOne. We work exclusively with eCommerce brands, so we know this space well. This guide is our honest view of the best eCommerce SEO agencies in the UK right now. Some of the agencies on this list are competitors. We’ve included them because they deserve to be here.
If you want to understand what specialist eCommerce SEO services look like for an online retailer, this is a good place to start. Looking for a general marketing agency rather than an eCommerce SEO specialist? Our roundup of the UK’s top SEO agencies covers a wider mix of sectors.
How we picked this list: a lot of “best eCommerce SEO agency” guides are published by one agency that ranks itself first, quotes a single flattering statistic and moves on. We’ve tried not to do that. Every agency below was shortlisted on the same criteria: genuine eCommerce specialism (not generalist SEO with an eCommerce case study bolted on), a named platform focus, evidenced client results and enough public information to check our claims. Yes, we’ve put ourselves first. So we’ve shown our own numbers, in full, in our profile. Where we’re not the right fit for a brand, we’ve said so
Best eCommerce SEO Agencies in the UK (2026)
There’s no single right answer when you choose an agency. The best fit depends on your platform, your category, your revenue stage and what kind of support you actually need. That said, the ten agencies below have genuine specialism, real results and the technical depth that eCommerce demands.
The short answer: eComOne is the best eCommerce SEO agency in the UK for brands turning over £3m or more that want organic revenue, not just rankings, and we won Integrated Agency of the Year (large) at the UK Agency Awards 2026. Novos suits content-led growth, Charle suits Shopify-first brands and Re:Signal suits enterprise catalogues. The full ranking is below.

1. eComOne: Lincoln, UK
Location: Lincoln, Lincolnshire
Best for: eCommerce brands focused on revenue from organic search
Platform expertise: Shopify, Magento, WooCommerce, BigCommerce, Custom Builds
We’ll start with ourselves. Not because we think we’re perfect, but because eCommerce is all we do. That focus matters.
eComOne was founded by Richard Hill, who scaled his own eCommerce store before he started the agency. That background shapes how we work. Every recommendation gets judged on its commercial impact first. Rankings are a signal, not the goal.
We’re a Google Premier Partner and a Shopify Plus Partner, and we’re B Corp certified. We’ve won Ecommerce Team of the Year and we’re named in the Sunday Times Top 100 Places to Work. In October 2026 we added Integrated Agency of the Year (large) and PPC Agency of the Year (large) at the UK Agency Awards. A judging panel checked our numbers, case studies and client feedback, and it singled out our long-standing client partnerships. You can read the full story in our awards write-up.
What we actually do well:
Our eCommerce SEO services are built around eCommerce from the ground up. That means category architecture, product page optimisation, crawl budget management and structured data, not just content and links.
For Shopify brands, our Shopify SEO work covers the platform-specific issues that catch a lot of agencies out: URL structure, canonical tag defaults, how Shopify handles collections and the relationship between your theme and your Core Web Vitals.
Technical SEO is a genuine strength. We do proper log file analysis, JavaScript rendering assessment and structured data implementation. For large catalogues, the technical foundations are where the biggest gains tend to come from.
On the AI search side, we’ve built dedicated capability through our AI solutions team, covering visibility audits, Generative Engine Optimisation (GEO), entity optimisation and structured data strategy. Our work with Safelincs is a good example: they’ve picked up more than 2,000 AI citations, reaching customers who never click a traditional search result.
We also integrate PPC with SEO delivery. When the same team is across both channels, you get joined-up keyword strategy, shared audience insight and a clearer view of where each channel earns its keep.
Notable clients
Brands we’ve worked with include Safelincs, Heinnie Haynes, Rimmer Bros, Locks Direct, RackZone, Splash About, Obam Stairlifts, Volvo Cars UK, Lincolnshire Radiators and MPG Group. Our case studies show the work behind each one.
Industries we work across: automotive, outdoor and sport, fashion, home and garden, petcare and B2B eCommerce.
Proven results
Here’s how organic search revenue has moved for four clients we run SEO for. The figures come straight from each client’s Google Analytics 4 account, for the 12 months to 18 October 2026 and compared with the 12 months before. They’re a selection, not every account we manage.
| Client | Organic search revenue | Organic transactions | Organic sessions |
|---|---|---|---|
| Safelincs | Up 38.2% | Up 13.4% | Down 38.6% |
| Heinnie Haynes | Up 24.4% | Up 27.7% | Up 9.7% |
| RackZone | Up 28.2% | Down 19.1% | Up 18.0% |
| Splash About (UK site) | Up 8.2% | Up 5.7% | Up 13.7% |
Look at Safelincs. Organic sessions fell by more than a third, and organic revenue still rose by more than a third. That’s why we report on revenue, not traffic. RackZone tells a similar story: fewer orders, but a much higher order value, so revenue grew.
Our published case studies add the longer view:
- Safelincs: more than 2,000 AI citations
- RackZone: number one in Google Ireland for “shelving” within three weeks, with a 32% rise in organic revenue
- Splash About: three regional Magento stores moved to one international Shopify build, with organic sessions, revenue and Google Ads revenue all up within four weeks
- MPG Group: five automotive brands stopped competing with each other in search, and the campaign made the Best Integrated Campaign (large) shortlist
- Also see our work for Heinnie Haynes, Rimmer Bros and Locks Direct
Pricing and offer
We don’t sell off-the-shelf packages. We scope each SEO retainer around your catalogue size, how competitive your category is, how many markets you sell in and how much content and PR you can handle in-house. You’ll find our estimates for the UK market in the cost section below, and we’ll give you a written proposal for your own site. Every project has an account manager, so you always know who to call.
We can’t promise rankings or a specific revenue figure, and we’d be wary of any agency that does. What we can promise is honest reporting tied to revenue.
The easiest way to start is a free SEO audit. Want to see how AI tools describe your brand? Ask for our free AI visibility audit too. Request yours here.
Why we’re on this list: we’re not the right fit for every brand. But if you’re an eCommerce business turning over £3m or more and you want an agency that ties everything back to revenue, we’re worth a conversation.

5. Charle, London, UK
Location: London, UK

What makes Charle different is that they combine Shopify SEO with Shopify development. That matters.

7. StudioHawk, UK/Australia (remote)

- Core services: Technical SEO, content SEO, link building, local SEO
- Industries: Retail, eCommerce, property, finance
- eCommerce strengths: SEO specialism, technical auditing, link acquisition
8. CEEK Marketing, London, UK
Location: London, UK
Best for: Lifestyle, fashion and consumer eCommerce brands
Platform expertise: Shopify, WooCommerce
CEEK are strong in the lifestyle and fashion space. Their work blends SEO with social and influencer marketing, which suits brands where search and brand visibility are closely connected.

- Core services: SEO, social media, influencer marketing, content
- Industries: Fashion, beauty, lifestyle, consumer goods
- eCommerce strengths: Brand-led SEO, Shopify optimisation, content strategy
9. Coalition Technologies, US/UK (remote)
Location: US/UK (remote)
Best for: Mid-market to enterprise eCommerce brands
Platform expertise: Shopify, Magento, WooCommerce, BigCommerce
Coalition Technologies is one of the larger agencies on this list. They’ve got an extensive case study library and the capacity to handle complex, multi-territory projects. Some UK brands find the time zone difference a limitation, so factor that into your decision.
- Core services: eCommerce SEO, PPC, web design, CRO, email marketing
- Industries: Fashion, retail, healthcare, B2B
- eCommerce strengths: Large catalogue SEO, cross-territory campaigns, technical complexity
10. WebFX, US/UK (remote)
Location: US/UK (remote)
Best for: Brands that want data-heavy reporting alongside SEO delivery
Platform expertise: Shopify, Magento, WooCommerce, BigCommerce
WebFX are known for their proprietary reporting technology. If attribution reporting is a priority alongside SEO, they’ve invested more in that area than most agencies. As with Coalition, the US base means UK clients should ask how account management works in practice.
- Core services: SEO, PPC, content marketing, email, social
- Industries: Retail, manufacturing, professional services, healthcare
- eCommerce strengths: Attribution reporting, integrated campaigns, category-level strategy
What Is an eCommerce SEO Agency?
An eCommerce SEO agency helps online retailers get more organic traffic from search engines. But the job is more specific than that sounds.
Think about the difference between optimising a fifteen-page services website and a product catalogue with 50,000 SKUs. The challenges aren’t just bigger. They’re different in kind. For most eCommerce brands, organic search also costs less to sustain than paid channels over the long run, and unlike paid spend, its value compounds. That’s the core commercial argument for hiring a specialist rather than handling SEO in-house at a surface level or through a generalist.
Whether you call it an eCommerce SEO agency, an eCommerce SEO company or simply SEO for your eCommerce website, the job is the same: engineering organic visibility for a product catalogue, not a handful of static pages. New to the topic? Start with our guide to what eCommerce SEO is.
eCommerce SEO agency vs eCommerce SEO consultant
The two terms get used almost interchangeably, but the practical difference is capacity. An eCommerce SEO consultant is usually one experienced person, covering strategy, technical audits and reporting alone. That can suit a smaller catalogue or a brand with in-house content and development resource that just needs direction. An agency brings a team: technical specialists, content writers, digital PR and account management working to one strategy. For a catalogue of any real size, the volume of work (category pages, product schema, ongoing content, link building, monthly reporting) usually needs more than one person’s time.
Here’s what makes eCommerce SEO distinct:
Category pages are where most organic revenue comes from. Getting them right means understanding keyword intent, user behaviour and how internal linking supports authority at scale.
- Technical SEO: faceted navigation creates duplicate content at scale. Crawl budget matters when Google is working through a large catalogue. Canonical tags, pagination and JavaScript rendering all need specialist attention.
- Structured data: Product, Review and Breadcrumb schema help Google and AI systems understand your catalogue. It’s not optional anymore.
- AI SEO: helping your products show up in AI Overviews, ChatGPT and Perplexity, not just traditional results, takes a different approach to content and authority than standard SEO.
- Shopify SEO services in the UK: Shopify has specific constraints around URL structure, canonical tags and collections. A proper service addresses them instead of applying a generic framework that misses the detail.
- CRO integration: more organic traffic doesn’t help much if your landing pages don’t convert. The best agencies treat CRO as part of the SEO process.
That’s why a generalist agency tends to underdeliver for eCommerce brands. The platform matters. The catalogue architecture matters. The commercial context matters. SEO is broad, and eCommerce SEO is a specialism within it.
What Services Should a Top eCommerce SEO Agency Offer?
There’s no shortage of agencies calling themselves eCommerce specialists. But what should that mean in terms of what they do?
The core services to look for:
Technical SEO is the foundation. Site auditing, crawl architecture, Core Web Vitals, canonical and hreflang implementation, log file analysis and structured data. Without solid technical foundations, content and links underperform.
Content optimisation covers category page copy, product page content, buying guides and blog content. The goal isn’t to fill pages. It’s to build topical authority and capture demand at every stage of the customer journey.
Digital PR and link building build the authority that makes your category pages competitive. Quality matters far more than volume. A handful of editorially earned links from relevant publications outperforms hundreds of directory listings.
CRO makes sure organic traffic converts. Heatmaps, A/B testing, user journey analysis and checkout optimisation all belong in the conversation.
Shopify SEO addresses the platform-specific issues generic SEO misses: theme performance, app stack conflicts, collection architecture and how Shopify Markets works for international expansion. When those are managed well, Shopify competes with custom-built platforms. The same logic applies to WooCommerce SEO services: plugin conflicts, hosting-related speed issues and category taxonomy all need dedicated attention rather than a generic WordPress checklist.
Generative Engine Optimisation (GEO) makes sure your brand appears in AI-generated results, not just traditional listings. That includes structured data strategy, conversational content and entity optimisation.
Google Merchant Centre optimisation connects your product feed to organic Shopping visibility. Feed quality and attribute completeness directly affect which products get surfaced.
International SEO covers hreflang implementation, market-specific keyword research and the strategic choice between subdirectories and subdomains for different markets.
SEO reporting should show you organic revenue and transaction data. If your monthly report only shows keyword positions and traffic, you’re missing the commercial picture.
How Much Does an eCommerce SEO Agency Cost?
There’s no single answer. But here are our own estimates for the UK market in 2026. They’re indicative ranges, not quotes from any agency on this list, so always ask for a written proposal.
Small eCommerce brands (under £1m annual revenue, a few hundred products) typically invest between £1,500 and £3,000 a month. At this level, activity focuses on technical foundations, priority category pages and early authority building.
Mid-market brands (£1m to £20m online revenue) usually invest between £3,000 and £8,000 a month. A comprehensive programme covering technical SEO, content strategy, digital PR and monthly reporting is achievable here.
Enterprise eCommerce stores (large catalogues, multiple markets, complex technical requirements) commonly invest upwards of £8,000 a month. Dedicated resource, international SEO strategy and integration with development teams become standard.
Project-based pricing is also common for defined deliverables such as technical audits and site migrations, where a fixed scope makes a retainer unnecessary.
What drives the cost up or down?
- Catalogue size and site complexity
- How competitive your category is
- The number of territories you’re targeting
- Existing technical issues that need fixing before growth work can begin
- How much of the content and digital PR work you can handle in-house
One thing worth saying clearly: cheap SEO carries real commercial risk. Low-cost providers often rely on methods that look good short term and cause damage over time. Recovering from a manual action or algorithmic penalty costs far more than doing it properly from the start.
On timescales: technical improvements and on-page optimisations can show measurable results within three to six months. Content-led authority building and digital PR typically take six to twelve months to deliver meaningful organic revenue uplift. For competitive categories, twelve to eighteen months is a realistic horizon. Our guide to how long eCommerce SEO takes to work goes into more detail. SEO compounds, and the brands that benefit most are the ones that commit to it consistently.
What Should You Look for in an eCommerce SEO Agency?
Choosing the right agency is harder than it should be. Here are the things that matter.
Genuine eCommerce experience. Ask specifically about eCommerce work. An agency that mostly handles lead generation websites won’t have deep knowledge of product catalogue management, category architecture or Merchant Centre. Ask for examples.
Platform expertise. If you’re on Shopify, ask how many Shopify brands they manage and what their Shopify-specific technical process looks like. Same question for Magento or WooCommerce. Vague answers are a red flag.
AI search capability. Any agency without a clear answer on how they’re approaching Google AI Overviews and Generative Engine Optimisation is behind. This isn’t a future consideration. It’s a present one.
Transparency. The best agencies can show you what they’re working on, why they’ve prioritised it and what they expect it to achieve. If they can’t explain their decision-making clearly, pay attention.
Reporting that shows revenue. Ask to see an example report. Does it show organic revenue and transactions, or just keyword rankings and traffic? You need the former to make good commercial decisions.
Proven results in your category. A strong case study in fashion is more relevant to a fashion brand than impressive results in an unrelated sector. Context matters.
Technical depth. Ask a technical question in the pitch. How do they handle faceted navigation duplicate content? What’s their approach to crawl budget on a large catalogue? What does their site migration process look like? The quality of the answer tells you a lot.
Commercial thinking. The best eCommerce SEO agencies think in revenue, customer acquisition cost and organic contribution to growth. If the conversation keeps coming back to rankings and traffic as the end goal, it’s not the right fit.
7 Red Flags When Choosing an eCommerce SEO or PPC Agency
The biggest danger rarely looks dangerous. It looks like a polished pitch deck. We made a short video on the warning signs, plus the questions to ask in the pitch so you can spot them early.
Here’s the short version:
- They lead with vanity metrics. Impressions, clicks, traffic and raw ROAS say little about profit.
- They over-promise before they’ve audited anything. No account, margin or tracking review means no basis for a promise.
- They dodge questions about attribution and tracking.
- The pitch team disappears after you sign.
- Their reporting looks polished but tells you almost nothing.
- They have no experience with your level of complexity. Think thousands of SKUs, seasonal stock, multiple regions and different margin profiles.
- They never ask about your margins. This one tells you almost everything about how an agency thinks.
A strong agency won’t mind any of these questions. They’ll welcome them, because they separate activity from growth. The same goes for PPC agencies as much as SEO ones.
How Search Is Changing for eCommerce Brands
Search in 2026 looks meaningfully different from three years ago. If your agency isn’t actively addressing this shift, you’re leaving something significant on the table. Ofcom’s Online Nation 2025 report found that Google is still the UK’s most-used search service, but that generative AI services are changing the sector.
AI SEO, sometimes called Generative Engine Optimisation, means optimising your website and content to appear in AI-generated outputs across Google AI Overviews, ChatGPT and Perplexity. It combines structured data, authority building, conversational content and product feed management. It’s not a replacement for traditional SEO. It’s a layer on top of it that matters more every month.
Google AI Overviews now appear for a broad range of commercial queries, especially at the consideration and informational stages. Ahrefs found that AI Overviews cut the organic click-through rate for the top-ranking page by 58%. Fewer clicks means each visit has to count, so revenue per visit matters more than raw traffic.
ChatGPT is increasingly part of how shoppers research higher-consideration purchases. Someone asking for the best trail running shoe under £120 gets a synthesised answer with recommendations. Appearing in that answer takes strong authority, solid structured data and content that shows real product expertise.
Perplexity draws on web sources to synthesise answers to complex queries, and it’s popular with research-minded, high-intent buyers. Clear, well-sourced, well-structured pages give it something worth citing.
Structured data has become critical. Product, Review and FAQ schema help AI systems interpret and represent your content accurately. Incomplete structured data is a growing competitive disadvantage.
Conversational search is reshaping keyword strategy. Optimising for head terms alone isn’t enough. You need content that answers the natural language questions people now ask AI tools directly, which takes a different content architecture from traditional keyword-focused SEO.
Product feed optimisation connects directly to AI-generated Shopping results. Feed quality and attribute completeness influence which products get surfaced. SEO and Merchant Centre management need to be treated as one discipline.
This is where specialist eCommerce SEO agencies are pulling ahead. If your current agency isn’t talking about this shift, ask why.
What Google’s September 2026 Spam Update Means for eCommerce Brands
Google’s September 2026 spam update began on 24 September and finished on 8 October. A spam update isn’t the same as a core update. It targets content that breaks Google’s spam policies. A core update re-ranks content more broadly. As of 20 October 2026, Google hasn’t announced a new core update, and you can check the Google Search Status Dashboard for the latest. Its guidance on core updates is still the place to start if your traffic moved.
Google doesn’t publish a checklist, so this is our reading of what it means for an online store:
- Give category pages real content. Original copy written by people who know the products beats thin, templated text.
- Show first-hand experience. Buying guides, size advice, fitting notes and honest comparisons tell Google and shoppers that a real expert is behind the page.
- Use AI as a helper, not a shortcut. Content produced with little effort or originality adds nothing, whoever or whatever wrote it. Have a person check every claim.
- Keep the technical basics tight. Crawl health, structured data and site speed still decide how much of your catalogue Google can use.
It’s also a good filter for agencies. Ask how they’ve handled Google’s recent updates for eCommerce clients, and ask to see the revenue, not just the rankings.
Frequently Asked Questions
What is an eCommerce SEO agency?
An eCommerce SEO agency, sometimes called an eCommerce SEO company, helps online retailers get more organic traffic from search engines. The work is distinct from general SEO because it involves optimising a full product catalogue rather than a handful of static pages: category architecture, product page optimisation, faceted navigation, crawl budget management and structured data at scale.
What services should a top eCommerce SEO agency offer?
Look for technical SEO (site auditing, Core Web Vitals, structured data), content optimisation for category and product pages, digital PR and link building, CRO integration, platform-specific work such as Shopify SEO or WooCommerce SEO services, Generative Engine Optimisation for AI search, Google Merchant Centre optimisation, international SEO and reporting that shows organic revenue rather than just rankings and traffic.
How much does an eCommerce SEO agency cost?
Our own estimates for the UK in 2026: small eCommerce brands (under £1m annual revenue) typically invest £1,500 to £3,000 a month. Mid-market brands (£1m to £20m online revenue) usually invest £3,000 to £8,000 a month. Enterprise eCommerce stores commonly invest upwards of £8,000 a month. Project-based pricing is also common for defined deliverables like technical audits and site migrations.
What should you look for in an eCommerce SEO agency?
Genuine eCommerce experience rather than generalist website SEO, proven expertise on your platform (Shopify, Magento, WooCommerce or BigCommerce), a clear approach to AI search and Generative Engine Optimisation, transparent decision-making, reporting that shows organic revenue rather than just rankings, proven results in your category, technical depth and a commercial rather than purely traffic-focused mindset.
What is the difference between an eCommerce SEO agency and an eCommerce SEO consultant?
An eCommerce SEO consultant is typically one person covering strategy, audits and reporting, which suits smaller catalogues or brands with in-house content and development resource. An eCommerce SEO agency brings a full team, including technical specialists, content writers and digital PR, working to one strategy. Most catalogues of any real size need the volume of work an agency provides.
How long does eCommerce SEO take to work?
Technical improvements and on-page optimisations can show measurable results within three to six months. Content-led authority building and digital PR typically take six to twelve months to deliver meaningful organic revenue uplift. For competitive categories, twelve to eighteen months is a realistic horizon for sustainable visibility.
Is eComOne an award-winning eCommerce SEO agency?
Yes. In October 2026, eComOne won Integrated Agency of the Year (large) and PPC Agency of the Year (large) at the UK Agency Awards, which are judged on evidence including results, case studies and client feedback. eComOne is also a Google Premier Partner, a Shopify Plus Partner and B Corp certified.
