Technical SEO Services

We run a full crawl, cross-reference it against Search Console coverage data and server logs where they are available, and produce an issue list scored by commercial impact rather than by tool severity rating.

• Crawlability — robots.txt directives, crawl budget waste, parameter handling, faceted navigation, pagination, internal redirect chains and loops.
• Indexation — coverage reports, noindex leaks, canonical correctness, duplicate and near-duplicate clusters, index bloat from filters and search result pages.
• Rendering — what Googlebot actually sees on JavaScript-heavy pages versus what a browser renders. This gap is where a surprising amount of "unexplained" ranking failure lives.
• Site architecture — click depth, internal link distribution, orphan pages, and whether link equity reaches the pages that need to rank.
• Structured data — schema coverage, validation errors, and the eligibility gaps that stop rich results appearing.
• Performance — Core Web Vitals measured against CrUX field data, not a one-off Lighthouse score on a fast connection.
• Security and delivery — HTTPS implementation, mixed content, HSTS, redirect correctness, and hosting-level response times.

Lighthouse gives you a lab score on a simulated device. Google ranks on field data — what real users on real connections actually experienced. These two numbers routinely disagree, and optimising for the lab score while field data stays red is one of the most common wasted efforts in technical SEO.

We work against CrUX field data and target the three thresholds that matter: Largest Contentful Paint under 2.5 seconds, Interaction to Next Paint under 200 milliseconds, and Cumulative Layout Shift under 0.1. INP replaced First Input Delay and is materially harder to pass, particularly on sites carrying heavy third-party tag loads — which in practice is most UK commercial sites.

The fixes are rarely glamorous: deferring non-critical JavaScript, setting explicit image dimensions, serving modern image formats, eliminating render-blocking resources, and auditing what your tag manager is actually loading. But they are measurable, and they hold.

The single most common serious issue we find on established UK sites is index bloat. A site with 800 genuine pages reports 140,000 indexed URLs, because filtered category views, internal search results, session parameters and paginated archives are all crawlable and indexable.

The cost is real. Crawl budget gets spent on URLs that will never rank, quality signals get averaged across a huge volume of thin pages, and the pages you actually care about get crawled less often. Resolving it means deciding, URL pattern by URL pattern, whether each should be indexed, crawled but not indexed, or blocked entirely — and then implementing that consistently across robots.txt, meta directives, canonicals and internal linking.

Site migrations are where most organic traffic gets lost, and almost always avoidably. The failure mode is consistent: the redirect map is built from the new site's structure rather than from what was actually ranking, so the URLs earning traffic get mapped to a category page or the homepage.

We handle migrations by crawling the live site first, cross-referencing every URL against Search Console performance data, and mapping one-to-one wherever an equivalent page exists. Anything without an equivalent gets a documented decision rather than a default. Post-launch, we monitor coverage and rankings daily for the first fortnight, because migration problems are cheap to fix in week one and expensive in month three.
