Crawl and indexation
Discovery, blocked resources, parameter handling, pagination and the difference between what Googlebot fetches and what users see.

Technical SEO that search engines can actually use
If Google cannot crawl, index or trust the site, content and campaigns waste money. Technical SEO is the engineering of those foundations: rendering, canonicals, sitemaps, robots, Core Web Vitals and schema that matches what the page really says. We implement the fixes rather than handing you a slide deck.
Technical SEO audits and fixes
Technical SEO is the engineering of crawl, indexation, canonicalisation, performance, structured data and rendering so search engines can understand a site and users can use it.
What technical SEO is for
- A crawl path that matches the URLs you actually want indexed
- Canonicals, robots and sitemaps that agree with each other
- Faster, more stable pages on mobile as well as desktop
- Structured data limited to what is visible and true
Who technical SEO is for
- Teams whose content is decent but pages will not index reliably
- Sites with duplicate URLs, parameter chaos or conflicting canonicals
- Businesses that need Core Web Vitals and rendering fixed, not another content calendar
Crawl, index and performance problems we fix
- Googlebot and users see different things
- Preview, staging or localhost URLs have leaked into production SEO
- JavaScript-rendered content is the only version of important copy
Canonicalisation
Self-referencing canonicals on indexable pages, no localhost or preview domains in production, and no accidental homepage canonical on inner URLs.
Performance
Core Web Vitals as a product of lean front-end work: images, fonts, JavaScript cost and server response — not a plugin lottery.
Structured data
A coherent graph of Organisation, WebSite, WebPage, Service and Breadcrumb entities. No fake reviews, no unsupported rich-result chasing.
Implemented, not recommended
The people who find the issue can change the Next.js app, the headers and the templates. That is the point of a technology company doing SEO.
Supports the SEO engagement
Technical SEO is not a substitute for content architecture or local work. Those remain on their own pages so the clusters do not fight.
We work with UK businesses. Berkshire and the South East — Newbury, Thatcham, Reading, Basingstoke, Oxford and Swindon — are a practical focus for local-service clients, not a limit on who we will work with.
Typical work on this engagement covers crawling, indexing, canonicalisation, robots.txt, sitemaps, structured data, Core Web Vitals and rendering.
Questions we are asked
- Is technical SEO a one-off audit?
- The first deliverable is usually a prioritised audit. The value is in the implementation. We do that work in the same team that can change the codebase.
- Do you only work on Next.js sites?
- Next.js is what this company uses for its own properties, but technical SEO applies to any serious stack. The principles are the same: crawlable HTML, clean canonicals, fast pages.
- Will you invent schema to chase rich results?
- No. We mark up what is visible and true. Fake review schema and doorway FAQ markup are liabilities.
