Ecommerce sites built to be found and built to convert.
Most online stores are designed to look good, then handed to an SEO agency to fix. We build them the other way round: fast, crawlable and structured to rank on the category and product pages that actually earn revenue.
Ecommerce website design is the practice of building an online store that is fast, easy to buy from and structured so search engines and AI assistants can read, rank and cite your product and category pages. Rogue Logic builds bespoke ecommerce sites engineered for Core Web Vitals, technical SEO and conversion from the first line of code, on the platform that fits your catalogue rather than a heavy off-the-shelf theme. Bespoke builds start at £5,000 plus VAT, with hosting and management on our own platform from £100 a month.
Ecommerce websites, in full.
Ecommerce is where technical SEO and conversion stop being separate conversations. A store lives or dies on the same handful of pages, the category listings that catch buyers mid-search and the product pages that turn interest into an order, and both have to be fast, readable and trustworthy at once. Get the engineering right and every other effort compounds on top of it. Get it wrong and you pay for the same weakness twice, once in rankings you never reach and again in carts nobody completes.
The failure modes are predictable. A heavy theme with a dozen plugins that drags Core Web Vitals into the red on mobile, where most of your buyers are. Faceted navigation that spawns thousands of near-duplicate URLs and splits the ranking signals your best categories depend on. Product pages thin on the words buyers and search engines actually look for. Checkout friction that quietly loses a share of every session that made it that far. None of these show up as a single obvious fault. They show up as a store that gets traffic but not orders, or orders but not the growth the numbers should support.
We build to remove those ceilings before they form. That means a store hand-built to be light and fast, an architecture that keeps faceted and filtered URLs under control, product and category templates structured with the right schema so they can be read and cited, and a checkout path stripped of the friction that costs conversions. It also means being pragmatic about platform. We build on what suits your catalogue and how you sell, headless, a modern hosted platform, or bespoke, rather than forcing every store onto the same stack.
This is senior work by design. Scoping a faceted-navigation strategy, planning a migration that keeps your existing rankings, or deciding where product schema ends and over-marking begins is judgement, not a checklist. The four of us have spent roughly forty years between us on exactly this kind of build, which is why we take on the stores other agencies called complicated.
Ecommerce websites, broken down.
Category and collection pages
Your highest-value ranking assets and most agencies treat them as an afterthought. We build category templates with genuine indexable content, clean internal linking and the right structure, so they rank for the commercial terms buyers search before they know your brand.
Product pages and product schema
Product pages structured with the detail buyers and search engines look for, marked up with Product and Offer schema so price, availability and reviews can be read and shown correctly in search and AI answers, without tipping into over-marking that gets ignored.
Faceted navigation and URL control
Filters and facets can spawn thousands of near-duplicate URLs that waste crawl budget and split signals. We plan which combinations should be crawlable and which should not, so authority points at the categories you want ranked.
Explore →Core Web Vitals under a real catalogue
Speed measured where it counts, on mobile, with product imagery and a full catalogue loaded, not a stripped test page. We fix performance at the source so it holds as the store grows.
Explore →Checkout and conversion path
The stretch from add-to-cart to confirmed order is where revenue leaks. We keep the path short, fast and clear, and structure it so you can see where sessions drop and why, rather than guessing.
Replatforming without losing rankings
Moving stores is where hard-won rankings vanish if the redirects are wrong. We migrate with a full URL map and redirect plan so you keep the traffic and revenue you already have.
Explore →The way we run Ecommerce websites.
Scope the store and the search
We start from how you need to be found and how you sell: the categories that carry commercial intent, the products that drive margin, the buyers and the AI surfaces. The build is designed around that, not around a template.
Design around the buying decision
A bespoke design built for your catalogue and your buyers, focused on the actions that turn a browse into an order, rather than a theme every competitor is also running.
Build clean, fast and structured
Hand-built and lightweight, with semantic HTML, product and category schema and a controlled URL architecture engineered in from the first line, so it is ready to rank and be cited at launch.
Wire up the commercial plumbing
Payments, inventory, shipping and the analytics that tell you what is actually selling, set up so the store runs cleanly and you can see the numbers that matter.
Migrate and launch safely
If you are replatforming, we launch behind a full redirect map so rankings and revenue carry over, and we verify against live crawl and index behaviour rather than assuming it worked.
Host, monitor and hold performance
Hosted and managed on our own platform where it is our build, kept fast, secure and technically healthy as the catalogue grows and the store changes.
How we approach Ecommerce websites.
Speed engineered in, not patched on
We hand-build light rather than bolting plugins onto a heavy theme, so product and category pages pass Core Web Vitals on mobile and stay fast under a real catalogue, not just on a launch-day demo.
Structured to rank and be cited
Semantic HTML, product and breadcrumb schema, clean category architecture and controlled faceted URLs, so search engines and AI assistants can read, rank and quote your pages instead of guessing at them.
Designed to convert, not just to browse
A bespoke design built around how your buyers decide and buy, with the friction taken out of the path from category to product to completed checkout.
Platform chosen to fit the catalogue
Headless, a modern hosted platform or bespoke, scoped to how you sell and how much you list, rather than one stack forced onto every store regardless of fit.
What Ecommerce websites puts on your desk.
Who builds your store, and how
Rogue Logic is the trading name of Bryley Ltd, a team of four senior practitioners with roughly forty years of combined experience between them. Your ecommerce build is scoped, designed and engineered by the people who have done it before, not passed down to a junior working from a template. We build stores the way search engines and buyers need them read, and we are honest about what we do and do not take on.
Senior hands on the build
Faceted-navigation strategy, product schema, migration planning and performance work are judgement calls, so they sit with experienced practitioners rather than a checklist run on autopilot.
Engineering, not plugins
We hand-build light and fix performance at the source, rather than stacking plugins onto a heavy theme and hoping the score holds once the catalogue is loaded.
Honest about scope
We build marketing-led ecommerce sites exceptionally well and host what we build. We will tell you plainly if a very large custom application is a better fit elsewhere, rather than selling you a build that is not ours to run well.
Ecommerce websites: common questions.
How much does ecommerce website design cost?
Bespoke ecommerce builds start at £5,000 plus VAT, scoped to your catalogue, platform and how you sell, with hosting and management on our own platform from £100 a month where it is our build. We price it properly on a call once we understand the store, rather than quoting a headline number that changes later.
Which ecommerce platform do you build on?
We are pragmatic about platform and choose it around your catalogue and how you sell: headless, a modern hosted platform, or a bespoke build. The point is a store that is fast, crawlable and structured to rank, not loyalty to one stack forced onto every client.
Can you make our ecommerce site rank in Google?
We build the technical and content foundations that ranking depends on: fast, crawlable category and product pages, clean architecture, controlled faceted URLs and the right schema. We cannot promise specific positions, and anyone who does is guessing, but we build so nothing on the site is holding your rankings back.
Will the store be fast on mobile?
Yes. We hand-build light and measure Core Web Vitals on mobile with a real catalogue and product imagery loaded, not a stripped test page, because that is where most ecommerce buyers are and where performance usually breaks.
How do you handle filters and faceted navigation?
Faceted navigation is where ecommerce SEO quietly goes wrong, spawning thousands of near-duplicate URLs that waste crawl budget and split signals. We plan which filter combinations should be crawlable and which should not, so authority concentrates on the categories you want ranked.
Can you rebuild or replatform our store without losing rankings?
Yes. Replatforming is where rankings vanish if the redirects are wrong, so we migrate with a full URL map and redirect plan, launch behind it, and verify against live crawl and index behaviour so the traffic and revenue you already have carry over.
Do you build the store so AI assistants can read it?
Yes. We use clean semantic HTML, Product and Offer schema and crawlable content so assistants can read, understand and cite your products, the same foundations that win classic search rather than a separate trick bolted on.
Do you host and maintain the ecommerce site?
We host and manage the stores we build on our own platform from £100 a month, kept fast, secure and technically healthy as the catalogue grows. We do not take on hosting for stores built elsewhere.
