Crawl budget is the first thing that matters at ecommerce scale. Large stores have far more URLs than search engines will crawl in any given period, so if crawlers waste their budget on thin, duplicate or parameter URLs, your important category and product pages get crawled less often and rank worse. We audit how search engines actually crawl your store, using log analysis where useful, and reshape crawl paths, robots rules and internal linking so crawl budget flows to the pages that earn revenue rather than to endless low-value URLs.

Faceted navigation is the single biggest crawl and duplicate-content trap on ecommerce sites. As shoppers filter a catalogue by attribute, the store can generate an enormous number of parameter URLs, and left unmanaged, search engines crawl and sometimes index thousands of thin, near-duplicate filtered views. On a big catalogue this both wastes crawl budget and dilutes the authority of your real category pages. We set precise rules for which filtered views are crawlable and indexable and which are not, so the store stays efficient and focused.

Duplicate content is pervasive on ecommerce sites and quietly scatters ranking signals. Products reachable through multiple categories, variant and sort URLs, parameterised and clean paths, and multi-store or multi-region versions can all create near-identical pages that compete with each other. We audit and fix canonicalisation, URL handling and parameter management across the store so each product and category concentrates its authority on one page instead of splitting it across duplicates.

Site architecture is the structural backbone that determines how well authority flows and how easily pages are found. A shallow, logical structure where important category and product pages are reachable in few clicks, with clear internal linking, helps both crawlers and shoppers, while a deep, tangled structure buries pages and wastes authority. We design and refine your store's architecture and internal linking so authority flows to priority pages and nothing important is stranded deep in the catalogue.

JavaScript rendering is an increasingly common technical issue, especially on modern and headless stores. If key content, links or metadata depend on JavaScript that search engines do not reliably render, pages that look fine to shoppers can be partly invisible to crawlers, capping rankings without any obvious symptom. We test how your store actually renders to search engines and fix rendering, so your content and links are fully visible and your fast front end does not come at the cost of visibility.

Core Web Vitals and speed are technical ranking factors that hit ecommerce hard, because stores are image-heavy and often script-heavy. Slow pages lose both rankings and conversions, and at scale even small speed problems compound across thousands of pages. We diagnose and fix the performance issues, image handling, scripts, caching, server response, that drag your store down, so it passes Core Web Vitals and loads fast for shoppers on every device.

Indexation control is a discipline of its own at ecommerce scale, and getting it wrong is expensive in both directions. Letting search engines index everything floods the index with thin, low-value pages and buries your best ones, while over-restricting can hide pages that should rank. We manage the balance deliberately, through robots rules, canonicalisation, internal linking and sitemap hygiene, so search engines index the pages that earn revenue and can find and prioritise them.

XML sitemaps and structured data are the machine-readable layer that helps large stores get fully discovered and richly displayed. Well-segmented sitemaps help search engines process tens of thousands of URLs and reveal indexation problems, while accurate product, review, breadcrumb and organisation markup earns rich results and helps AI systems understand your catalogue. We implement and maintain both at scale, so your store is both fully crawlable and richly represented in the results.

The rise of AI answers raises the stakes on technical SEO rather than lowering them. AI Overviews and assistants can only draw on content they can crawl, render and clearly understand, so the same technical foundation that wins classic rankings determines whether your products can be cited in AI answers. A technically sound, well-structured store is far more likely to be surfaced there, which is why this work underpins the visibility we build through our generative engine optimization approach as well.

International and multi-region stores add a technical layer that is easy to get wrong. Serving multiple languages or regions requires correct hreflang, careful canonicalisation and clear region signals, or the versions duplicate and compete, splitting authority and confusing which should rank where. We configure the technical internationalisation so each version clearly serves its market, turning global expansion into added organic reach rather than internal competition.

Migrations and replatforms are the highest-risk technical moments for any store, and where specialist technical SEO pays for itself many times over. Restructuring URLs, changing platforms or redesigning without careful redirect mapping and preservation of the elements search engines rely on can wipe out organic revenue overnight. We plan and execute the technical side of migrations, redirect mapping, structure preservation, testing and monitoring, so you keep the rankings and revenue you have earned and often improve on them.

Underneath all of it, we treat technical SEO as the foundation that makes everything else work rather than a one-off audit. A large store's technical health drifts as products change, apps are added and the site evolves, so we not only fix the current issues but put monitoring and processes in place to catch new ones early. That way your content and authority investments keep paying off, and the whole effort connects up to our ecommerce SEO hub for the store as a whole.

Pagination and sorting are subtle technical traps that large catalogues rarely handle well. Category pages split across many paginated views, plus sort-order variations, can create crawl inefficiency and dilute signals if handled carelessly, leaving deeper products under-crawled and paginated pages competing with one another. We implement sensible pagination and sorting handling so search engines can reach the full catalogue efficiently and consolidate signals where they belong, rather than getting lost in an endless series of parameterised pages.

Out-of-stock, discontinued and seasonal products are a technical problem at scale, not just a merchandising one. Thousands of products that sell out, get retired or return seasonally can accumulate into dead-end URLs, soft 404s and fluctuating pages that confuse search engines and waste crawl budget. We put clear technical rules in place, keeping and repurposing pages with lasting demand, redirecting the ones truly gone, and preserving the ranking equity of seasonal lines, so product lifecycle changes do not quietly erode your technical health.

We work as a genuine partner to your development team, because ecommerce technical SEO is only valuable once it ships. Many fixes require developer time and touch a live store where a careless change can break things, so we specify each fix precisely, prioritise by revenue impact, provide clear implementation guidance, and test on staging where it matters. That collaboration is what turns a technical audit into shipped improvements and recovered rankings rather than a backlog document that ages while organic revenue keeps leaking.

Finally, we treat technical measurement as part of the work, not an afterthought. We track crawl stats, indexation coverage, Core Web Vitals, and the rankings and organic revenue of the pages our fixes target, so the impact of technical work is visible rather than assumed. Because technical SEO can feel abstract, tying it to crawl efficiency, index coverage and revenue is how we prove it is working and decide where to invest next, keeping the effort accountable to results.

Mobile-first indexing means the mobile version of your store is what search engines actually rank, and on ecommerce sites the mobile experience often quietly differs from desktop in ways that hurt. Content hidden on mobile, links that only appear on larger screens, or a stripped-down mobile layout can leave your rankings resting on a weaker version of each page. We make sure your mobile store carries the full content, links and structured data search engines need, so mobile-first indexing works for you rather than against you.

Hosting, server response and infrastructure sit underneath every other technical factor, and on a busy store they matter more than owners expect. Slow server responses, unreliable uptime during traffic spikes, or misconfigured caching and delivery can throttle crawling and hurt both rankings and conversion no matter how well the front end is built. We assess the infrastructure side and work with your hosting or platform so the store responds quickly and reliably to shoppers and crawlers alike, giving the rest of the technical work a solid base to stand on.

Crawl budget and log analysis. We audit how search engines actually crawl your store, using log analysis where useful, and reshape crawl paths, robots rules and internal linking so crawl budget flows to the pages that earn revenue instead of endless low-value URLs.

Faceted navigation management. We set precise rules for which filtered and sorted views should be crawlable and indexable, so your catalogue's filters stop generating thousands of thin, near-duplicate URLs that waste crawl budget and dilute your category pages.

Duplicate content and canonicals. We fix the canonicalisation, URL and parameter handling that let stores serve the same product or category at multiple URLs, so each page concentrates its authority instead of splitting ranking signals across duplicates.

Site architecture and internal linking. We design a shallow, logical structure with clear internal linking so important pages are reachable in few clicks and authority flows to priority category and product pages instead of stranding them deep in the catalogue.

JavaScript rendering and headless SEO. We test how your store renders to search engines and fix rendering issues so content, links and metadata are fully visible, letting modern and headless stores keep their speed without sacrificing crawlability or rankings.

Core Web Vitals and performance. We diagnose and fix the image, script, caching and server issues that slow image-heavy stores, so your site passes Core Web Vitals and loads fast for shoppers, protecting both rankings and conversion across thousands of pages.

Indexation, sitemaps and structured data. We manage indexation with robots rules, canonicalisation and internal linking, maintain well-segmented XML sitemaps, and implement accurate product and review markup, so your store is fully crawlable, correctly indexed and richly represented in the results.

Migration and international technical SEO. We handle the technical side of migrations and replatforms with careful redirect mapping and structure preservation, and configure hreflang and region signals for multi-region stores, so changes and expansion protect rather than damage your organic revenue.
