You’ve got an online store. Products are listed, the checkout works and the delivery options are sorted. So why is nobody visiting?
This is where eCommerce SEO comes in. It’s the practice of getting your online store to appear in search engines when people are actively searching for what you sell. Not through paid ads, but by earning those positions organically. When someone types “best waterproof jacket for hiking” or “affordable standing desk UK” into Google, eCommerce SEO decides whether your store appears at the top or sits on page four, where the tumbleweeds live.
This guide explains how it works, what it covers and how to start. We’ve also added something most guides can’t: real numbers from 20 of our own client stores, including how much revenue organic search drives, how it compares with every other channel and how much traffic AI assistants like ChatGPT now send.
What is eCommerce SEO? eCommerce SEO is the practice of getting your online store to appear in search engines when people look for what you sell, without paying for each click. It covers keyword research, on-page optimisation, technical health, content and links across your product and category pages. Our eCommerce SEO services do this work for eCommerce brands turning over £3m or more.
Key Takeaways
- Organic search was the biggest single revenue channel across 20 of our client stores, at 31.7% of online revenue.
- Paid search earns more per visit (£4.47 against £2.09 for organic), so the strongest stores run both.
- Category pages, not product pages, are usually where the biggest wins sit.
- Free Google Shopping listings converted at 3.0%, the highest rate of any channel we measured.
- AI assistants sent 48,823 visits to those stores, and those visitors converted at 2.17%, about 1.6 times the organic rate.
- Google’s new agentic shopping tools reward complete, accurate product data, so your feed is now part of your SEO.

What Is eCommerce SEO, Exactly?
eCommerce SEO is SEO built around one outcome: orders. Instead of chasing traffic for its own sake, you optimise the pages that sell (category pages, product pages and the guides that feed them) so that shoppers searching to buy find your store first.
It’s also bigger than keywords. It covers how your site is built, how fast it loads, how your product data is structured and what happens after the click. A page that ranks but frustrates people on the way to checkout hasn’t done its job.
Four groups of work make up the discipline: keyword and content strategy, on-page optimisation, technical SEO and authority building (links and brand signals). We’ll cover each below. The principles also apply beyond classic online shops. Any site selling products, from marketplaces to B2B catalogues, faces the same issues.
How eCommerce SEO Differs From Regular SEO
General SEO principles apply everywhere, because relevance, authority and technical health are universal. But an online store brings problems a blog or a brochure site never meets. Scale is the obvious one, and duplication is the sneaky one. Manufacturers send the same product copy to every retailer, so thousands of stores publish identical text and Google has to pick a winner. It rarely rewards stores that made no effort.
| Regular SEO | eCommerce SEO | |
|---|---|---|
| Goal | Traffic, leads or enquiries | Orders and revenue |
| Main page types | Articles, service pages, landing pages | Category pages, product pages, filtered pages, buying guides |
| Scale | Dozens to hundreds of URLs | Thousands to millions of URLs |
| Search intent | Mostly informational | Mostly commercial and transactional |
| Duplicate content | Occasional | Constant: manufacturer copy, product variants, filter URLs |
| Page lifecycle | Pages are long-lived | Products go out of stock, get discontinued or return seasonally |
| Technical focus | Speed, indexing, mobile | All of that plus faceted navigation, crawl budget and product schema |
| Success measure | Rankings, traffic, leads | Organic revenue, transactions, average order value |
Where eCommerce Revenue Really Comes From: Our Channel Data
Most guides repeat one cross-industry statistic. BrightEdge’s research puts organic search at around half of all website traffic on average. That’s a useful starting point, but it says little about stores. So we looked at our own data.
We pulled 12 months of Google Analytics 4 data for 20 eCommerce sites we work with, covering about 25 million sessions and £47.7m in online revenue. Here’s how each channel performed.

Revenue per session by channel (£)
Source: eComOne client Google Analytics 4 data, 20 eCommerce sites, default channel grouping, purchase revenue, 12 months to 18 October 2026. A selection of our clients, not the whole market.
Four things stand out:
- Organic search is the biggest revenue channel. It drove 31.7% of revenue from 28.9% of sessions, and organic revenue across these sites grew 9.1% year on year.
- Paid search is more efficient per visit. It earned £4.47 a session against £2.09 for organic, but organic delivered nearly twice the revenue because it brought far more visitors. That’s the case for running both.
- Direct and social are weak earners. Direct traffic produced £1.22 a session and paid social just £0.49. Organic social managed £0.15. For many stores, search is where the buying happens.
- Organic does it without a bid. Every organic visit costs nothing in clicks, and strong rankings keep working long after the work is done.
Your numbers will differ. Category, brand strength and ad spend all move the mix. Across our four most-studied clients, organic’s share of revenue ranges from 5.2% to 41.1%. The point isn’t a universal percentage. It’s that you should know yours.
| Channel | Share of revenue | Share of sessions | Conversion rate | Revenue per session | Average order value |
|---|---|---|---|---|---|
| Organic Search | 31.7% | 28.9% | 1.33% | £2.09 | £156 |
| Direct | 19.9% | 31.0% | 0.78% | £1.22 | £156 |
| Paid Search | 17.6% | 7.5% | 2.95% | £4.47 | £152 |
| Cross-network (Performance Max style) | 15.7% | 11.4% | 2.27% | £2.61 | £115 |
| Paid Shopping | 4.8% | 4.2% | 1.78% | £2.14 | £120 |
| 4.0% | 4.7% | 1.25% | £1.63 | £131 | |
| Paid Social | 0.9% | 3.6% | 0.53% | £0.49 | £93 |
| Organic Shopping (free listings) | 0.7% | 0.5% | 3.01% | £2.45 | £81 |
| AI Assistant | 0.2% | 0.2% | 2.17% | £2.31 | £106 |

Channels follow GA4’s default grouping, and some AI and direct visits arrive without a referrer, so treat the smaller channels as a floor, not a ceiling.
The Four Pillars of an eCommerce SEO Strategy
No single thing makes eCommerce SEO work. It’s a combination of four disciplines, and weakness in one tends to hold back the others.
1. Keyword and Content Strategy: Understanding How Your Customers Search
Before a single page gets optimised, you need to know how your customers actually search. Not how you assume they search. Tools like Google Search Console, Ahrefs and Semrush surface the data, but the real skill is reading it with some commercial common sense.
eCommerce keywords work in layers. Head terms like “running shoes” bring huge traffic and brutal competition. Mid-tier terms like “mens trail running shoes” balance volume with intent. Long-tail searches like “mens wide fit trail running shoes waterproof size 11” are where the magic happens, because the person typing that already knows what they want. Match each type to the right page:
| Keyword type | Example | Intent | Best page to target |
|---|---|---|---|
| Category | trail running shoes | Commercial | Category page |
| Product or model | Salomon Speedcross 6 mens | Transactional | Product page |
| Long-tail attribute | wide fit waterproof trail shoes size 11 | Transactional | Filtered category or product page |
| Comparison | Salomon vs Hoka trail shoes | Commercial | Comparison guide linking to products |
| Informational | how to choose trail running shoes | Informational | Buying guide linking to categories |
| Brand | your store name | Navigational | Homepage and brand pages |
2. On-Page Optimisation: Where Rankings Are Won and Lost
With a keyword strategy in place, optimisation can begin. Product pages are the natural starting point and, honestly, the most neglected corner of most stores.
Writing Product Descriptions That Actually Do Something
Copy-pasting a manufacturer description might feel efficient, but it creates a real problem. If fifty other retailers have the same text, yours adds nothing new, and Google can tell. Writing descriptions that explain who a product is for, what problem it solves and why it’s worth buying improves rankings and conversions at once. Good SEO copy and good sales copy rarely conflict.
Category Pages: The Most Underestimated Pages in Your Store
Category pages deserve at least as much attention as product pages, and arguably more. They’re often the highest-traffic, highest-intent pages on a whole store, yet they’re regularly left as bare grids of products. A well-optimised category page has a clear H1, a short introduction that signals its purpose and enough supporting content for Google to understand its context, without reading like a keyword list forced into a suit.
Title tags and meta descriptions round out the essentials. Your title tag is the clickable headline in search results, so it needs your primary keyword and a reason to click. Meta descriptions don’t directly affect rankings, but they affect whether someone chooses your result over the one next to it. Add product schema (price, availability and review ratings) so those details can appear in search. Our eCommerce SEO services cover all of this, from product page audits to full category optimisation.
3. Technical SEO: The Infrastructure Beneath Everything
Technical SEO covers the behind-the-scenes factors that decide whether Google can crawl, understand and index your site. Think of it as the plumbing: invisible when it works, impossible to ignore when it doesn’t. A technical issue can cost you rankings for months before anyone notices.
| Technical Factor | Why It Matters | Common Fix |
|---|---|---|
| Site speed | Slow pages lose customers and rankings at the same time. Google’s Core Web Vitals targets are LCP under 2.5 seconds, INP under 200ms and CLS under 0.1 | Compress images; audit third-party scripts |
| Crawl budget | Large sites waste budget on low-value URLs | Use canonical tags and robots.txt correctly |
| Structured data (schema) | Enables rich results such as star ratings and prices, and helps AI systems read your products | Implement product and review schema |
| Mobile performance | Google mainly uses the mobile version of your pages for indexing | Test regularly with Lighthouse and Search Console |
| URL structure | Clean URLs are easier for Google and users alike | Use logical, keyword-relevant URL paths |
| Duplicate content | Confuses search engines and dilutes authority | Canonicalise variants; write original copy |
4a. Content Marketing: Earning Trust Before the Sale
Product pages capture people who already know what they want. Content marketing captures everyone else: the researchers, the comparers, the people three searches away from becoming customers.
A buying guide, a considered comparison or a genuinely useful answer to your customers’ most common question builds the trust that makes someone choose your store over a faceless marketplace. Link every guide to the category pages it supports. You can see a real example in our Safelincs SEO case study, where a consistent content strategy helped the brand earn authority in both traditional search and AI-generated results.
4b. Link Building: Why What Others Say About You Still Matters
Links from reputable websites remain one of the strongest signals Google uses to judge trust. A link from a respected industry publication tells Google something on-page work can’t: people outside your own website think you’re worth referencing.
Digital PR is one of the most effective routes for eCommerce brands. Create something genuinely interesting (original research, useful data, a fresh angle) and give writers a reason to link to it. Our SEO services include link building and digital PR, and our RackZone work shows what a targeted link gap strategy can do.
How to Start: A 90-Day eCommerce SEO Plan
Not sure where to begin? This is the order we’d tackle things in, and it’s the same logic we follow with new clients. Adapt it to your catalogue size.
| When | Focus | What you do |
|---|---|---|
| Weeks 1 to 2 | Baseline and audit | Record organic revenue and transactions in GA4. Check indexing and crawl errors in Search Console. Run a full site crawl. |
| Weeks 3 to 4 | Fix technical blockers | Resolve indexing problems, canonical and redirect errors, slow templates and missing product schema. |
| Month 2 | Category pages | Take your ten highest-revenue categories. Rewrite H1s, titles and introductions, and strengthen internal links to them. |
| Month 2 to 3 | Product pages | Replace manufacturer copy on your best sellers. Add reviews, FAQs and complete product data. |
| Month 3 | Content and authority | Publish buying guides that link to your categories. Start a link building or digital PR campaign. |
| Every month | Report on revenue | Track organic revenue, conversion rate and crawl coverage. Rankings alone aren’t enough. |
New Trends Reshaping eCommerce SEO in 2026
Search is changing faster than at any point in the last decade. These are the shifts we’re seeing, backed by data wherever we have it.
1. AI Overviews are cutting clicks
Google AI Overviews now sit above the organic results for many commercial queries. Ahrefs found that AI Overviews cut the organic click-through rate for the top-ranking page by 58%, using December 2025 data. Fewer clicks means every visit has to earn its place, so revenue per visit matters more than raw traffic.
2. AI assistants now send real buyers
GA4 now has an “AI Assistant” channel. Across our 20 stores it logged 48,823 sessions in 12 months, 94% of them from ChatGPT and 4.6% from Gemini. It’s tiny (0.2% of sessions), but those visitors converted at 2.17%, about 1.6 times the 1.33% organic rate. Safelincs, which has earned more than 2,000 AI citations, converted its AI visitors at 4.8%.
3. Free Shopping listings convert best
Our “Organic Shopping” channel (free Google product listings) is small, at 0.5% of sessions, but it converted at 3.01%, the highest rate of any channel we measured. A clean, complete product feed in Google Merchant Center is a cheap way to capture shoppers who are ready to buy.
4. Agentic commerce is arriving
In January 2026 Google launched the Universal Commerce Protocol (UCP), an open standard that lets AI agents browse, build a cart and check out for shoppers. At Google I/O in May it added a Universal Cart and “conversational attributes” for Merchant Center, which cover things like product Q&A, compatibility and substitutes. Checkout is rolling out to selected merchants, starting in the US, so UK availability is still to come. The lesson for UK stores is already clear: complete, accurate product data is now an SEO asset.
5. Spam updates punish scaled thin content
Google’s September 2026 spam update ran from 24 September to 8 October. A spam update targets content that breaks Google’s spam policies, and it’s different from a core update. As of 20 October 2026, Google hasn’t announced a new core update. You can check the Google Search Status Dashboard for the latest. For eCommerce, the message is simple: write original product copy, don’t mass-produce thin pages and keep filter URLs under control.
6. Your product feed is part of SEO
Google’s shopping surfaces, AI answers and agents all read your structured product data. If your feed has missing attributes, wrong prices or thin descriptions, you’re invisible in places your page-level SEO can’t reach. SEO and feed management now belong in the same conversation. If you’d like to see how AI tools currently describe your store, ask us for a free AI visibility audit.
How Long Does eCommerce SEO Take?
Honest answer: meaningful movement typically starts appearing within three to six months. A strong, sustainable organic presence usually takes twelve months or more of consistent work. Our guide to how long eCommerce SEO takes to work goes into more detail.
That timeline makes some people hesitant, which is understandable. But the economics shift over time. A product page that ranks well drives traffic every single day without costing a penny per click. Paid advertising stops the moment you stop spending. Running both works well: ads provide immediate visibility and SEO builds something more durable underneath. Our own data shows why. Paid search earned the most per visit, and organic search earned the most overall. Our PPC service sits alongside our SEO work for exactly that reason.
What Good eCommerce SEO Results Look Like
Measuring SEO properly means looking beyond keyword positions. Rankings are a useful indicator, but revenue is the goal. The metrics worth tracking regularly include:
- Organic traffic: total sessions from search, tracked as a trend rather than a snapshot
- Organic revenue: because traffic that doesn’t convert is just a vanity metric with good numbers
- Click-through rate (CTR): whether your titles and descriptions earn the click
- Crawl coverage: tracked in Google Search Console, confirming that your important pages are indexed
- Core Web Vitals: Google’s page experience signals
- AI referrals: sessions from ChatGPT, Gemini and other assistants, now visible in GA4
Here’s what that looks like for four of our clients. The figures come from each client’s Google Analytics 4 account for the 12 months to 18 October 2026, compared with the 12 months before. They’re a selection, not every account we manage.
| Client | Organic share of site revenue | Organic revenue vs previous 12 months | Organic sessions vs previous 12 months |
|---|---|---|---|
| Safelincs | 14.4% | Up 38.2% | Down 38.6% |
| Heinnie Haynes | 41.1% | Up 24.4% | Up 9.7% |
| RackZone | 5.2% | Up 28.2% | Up 18.0% |
| Splash About (UK site) | 20.0% | Up 8.2% | 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.
Our published case studies add the longer view. Each figure covers the period that case study reports on:
- Heinnie Haynes: 32.9% revenue growth
- Rimmer Bros: 21.1% increase in organic revenue
- Locks Direct: 52% increase in organic revenue
- RackZone: 32% increase in organic revenue
- Safelincs: more than 2,000 AI citations
Brands we’ve worked with include Safelincs, Heinnie Haynes, Rimmer Bros, Locks Direct, RackZone, Splash About, Obam Stairlifts, Lincolnshire Radiators and MPG Group. In October 2026 we also won Integrated Agency of the Year (large) and PPC Agency of the Year (large) at the UK Agency Awards. Read the full story in our awards write-up.
How Much Does eCommerce SEO Cost?
There’s no single answer, because cost depends on catalogue size, how competitive your category is and how many markets you sell in. These are our own estimates for the UK in 2026. They’re indicative ranges, not quotes, so always ask for a written proposal.
- Small stores (under £1m annual revenue, a few hundred products): typically £1,500 to £3,000 a month
- Mid-market brands (£1m to £20m online revenue): usually £3,000 to £8,000 a month
- Enterprise stores (large catalogues, multiple markets): commonly £8,000 a month or more
In-house or agency? A single in-house marketer can cover the basics for a small catalogue. As you grow, the work spreads across technical fixes, content, links and reporting, and it’s hard for one person to cover it all. Many brands keep strategy and brand knowledge in-house and bring in a specialist for technical depth and capacity.
We scope every retainer around your site and goals, and every project has an account manager. We can’t promise rankings or a specific revenue figure, and we’d be wary of any agency that does. The easiest way to start is a free SEO audit. Request yours here. Comparing agencies? Our guide to the best eCommerce SEO agencies in the UK shows how we rank the options, ourselves included.
Common eCommerce SEO Mistakes (and How to Avoid Them)
Even experienced store owners fall into the same traps. Most are fixable once you know they exist.
| Mistake | The Problem | The Fix |
|---|---|---|
| Duplicate product descriptions | Google may not rank any version of the page well | Write original copy for every product |
| Ignoring category pages | Missed traffic and revenue at the highest-intent stage | Add structured content and clear H1s |
| No internal linking strategy | Google struggles to understand your site structure | Link between related products and categories |
| 404 errors on out-of-stock products | You lose the SEO authority built on that URL | Keep the page live for temporary stock-outs, or redirect to a relevant alternative if the product has gone for good |
| Unmanaged filter URLs | Crawl budget wasted on near-duplicate pages | Canonicalise or block via robots.txt |
| Incomplete product feed | Invisible in Google Shopping, AI Mode and agentic tools | Fill every supported attribute and keep prices and stock accurate |
| Measuring rankings, not revenue | You can’t tell whether SEO is paying for itself | Report on organic revenue, transactions and conversion rate |
| Missing image alt text | Missed opportunity for image search rankings | Describe images naturally using relevant terms |

Frequently Asked Questions About eCommerce SEO
What is eCommerce SEO?
eCommerce SEO is the practice of getting your online store to appear in search engines when people look for what you sell, without paying for each click. It covers keyword research, on-page optimisation, technical health, content and links across your product and category pages.
How is eCommerce SEO different from regular SEO?
eCommerce SEO focuses on orders rather than traffic or leads. It deals with thousands of category, product and filter pages, constant duplicate content, products that go in and out of stock and technical issues such as faceted navigation and crawl budget.
Can I do eCommerce SEO myself?
The fundamentals are accessible to anyone willing to learn. However, as stores grow, the technical complexity and volume of work involved usually makes working with a specialist more efficient than managing everything in-house.
Does having more products automatically improve SEO?
No. More pages create more opportunities but also more risk. Thin descriptions, duplicate content and poorly structured URLs can work against you. Quality and structure matter far more than volume alone.
What is the difference between eCommerce SEO and PPC?
SEO drives organic traffic through earned search rankings. PPC means paying for ad placements in search results. In our client data, paid search earned £4.47 per session against £2.09 for organic, but organic delivered more total revenue, so most successful stores run both.
Is eCommerce SEO worth the investment?
For most stores with serious growth ambitions, yes. Organic search was the biggest revenue channel across 20 of our client stores, at 31.7% of online revenue. Businesses that invest consistently tend to become hard to compete with, because they build authority, content and rankings that would cost a significant sum to replicate through paid advertising.
How long does eCommerce SEO take to show results?
Meaningful movement typically starts appearing within three to six months. A strong, sustainable organic presence usually takes twelve months or more of consistent work to build.
Why are category pages so important for eCommerce SEO?
Category pages are often the highest-traffic, highest-intent pages on an entire store, yet they’re regularly left as bare grids of products with no supporting content. A well-optimised category page with a clear H1, an introductory paragraph and supporting content can drive significant organic traffic and revenue.
Does ChatGPT send traffic to eCommerce stores?
Yes, but not much yet. Across 20 of our client stores, AI assistants sent 48,823 sessions in 12 months, about 0.2% of all sessions, and 94% of them came from ChatGPT. Those visitors converted at 2.17%, compared with 1.33% for organic search, so the traffic is small but valuable.
What metrics should I track for eCommerce SEO?
The key metrics are organic traffic, organic revenue, click-through rate (CTR), crawl coverage via Google Search Console, Core Web Vitals and AI referral sessions. Tracking these together rather than in isolation gives a reliable picture of whether your strategy is working.
How much does eCommerce SEO cost in the UK?
Our own estimates for 2026: small stores (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, and enterprise stores commonly invest £8,000 a month or more. Always ask for a written proposal.
