Technical SEO in London
Fixing the reasons a London business's site cannot rank regardless of how good its content is — pages search engines never reach, duplicate URLs splitting signals, slow rendering, or a staging site accidentally indexed alongside the real one and competing with it for the same terms.
Why this comes up
The problem
Content and links get invested in while the site quietly blocks crawling, serves the same page at four URLs, or renders nothing without JavaScript. The foundation undoes the work above it.
What you get
What we deliver
- Crawl of the whole site, finding what search engines can and cannot reach
- Indexation reviewed — what is indexed that should not be, and what is missing
- Duplicate URLs resolved with canonicals and consistent internal linking
- Core Web Vitals measured on real user data rather than a lab score
- JavaScript rendering checked, since content only in the client is often not indexed
- Redirects, status codes and sitemaps corrected, with a prioritised fix list

Technical SEO in London — common questions
- How do we know if we have a technical problem?
- Common signs are pages that never appear in search however well written, traffic dropping after a redesign, or Search Console reporting far fewer indexed pages than you have. An audit answers it definitively and is cheap relative to what it can reveal.
- Does site speed actually affect rankings?
- It is a ranking factor and a modest one — a fast site does not outrank a better answer. Its real effect is on conversion, where the difference is far larger than the ranking benefit.
- Our site is built in React. Is that a problem?
- It can be. Search engines render JavaScript but slowly and imperfectly, so client-only content is often indexed late or not at all. Server rendering or static generation resolves it, and that is an architecture decision rather than a setting.
- What is the most common serious issue you find?
- Accidental blocking — a robots directive or noindex tag left over from staging that quietly removes whole sections from search. It is trivial to fix and often has been costing traffic for months.
- Do you work with businesses across Greater London?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of London businesses do you usually work with?
- Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
- Do you cover the areas around London?
- Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
