Quick answer
- Technical SEO makes sure search engines can reach, render and index your important pages quickly.
- We diagnose with crawl data, Search Console and log evidence, then write tickets developers can ship.
- Typical fixes: indexation, canonicals, redirects, JavaScript rendering, structured data and Core Web Vitals.
- It is implementation support, unlike the broader SEO audit, which diagnoses and prioritises.
What technical SEO consulting covers
Technical SEO is the work that lets search engines access, understand and trust your website. If a page cannot be crawled, rendered or indexed, no amount of content or link building will help it rank. Our technical SEO services are built around that simple dependency chain: crawl, render, index, rank. We locate the first link that is broken and fix it before moving on.
As a technical SEO consultant, we work alongside your developers instead of handing over a report and disappearing. That means writing tickets with clear acceptance criteria, reviewing pull requests or staging builds, and verifying in Google Search Console that the change had the intended effect.
Crawling and indexation problems we fix
Crawl and index issues are the most common reason a good page does not appear in Google. We check robots directives, XML sitemaps, canonical tags, noindex rules, redirect chains and server responses, and compare what you submit with what Google has actually indexed. Our guides on crawling versus indexing and canonical tags and duplicate URLs explain the concepts if you want the background.
For larger sites we also review crawl budget in practice: whether parameters, faceted URLs or endless calendars are wasting Googlebot’s attention. The aim is simple. Your most valuable pages should be easy to find, quick to fetch and clearly identified as the preferred version.
Rendering, JavaScript and site speed
Modern sites often depend on JavaScript to show content. If key text or links appear only after scripts run, search engines may see less than visitors do. We test rendered HTML against source HTML, identify what is missing, and recommend practical fixes, from server-side rendering to simpler templates. See our JavaScript SEO guide for the checks involved.
Speed matters for people and for search. We measure Core Web Vitals using field data wherever available, trace slow pages to their real causes such as heavy images, render-blocking scripts or third-party tags, and give developers specific changes rather than generic advice. Background reading is in our Core Web Vitals guide.

Structured data and site architecture
Structured data helps search engines and AI systems understand who you are, what you offer and how pages relate. We specify JSON-LD for organisations, services, articles, FAQs and breadcrumbs, validate it, and keep it consistent with visible content. Our structured data guide for service businesses covers the principles.
Architecture is the other half of understanding. URL logic, navigation and internal links decide where authority flows. We map the structure to your commercial priorities so important pages are never buried; see website architecture and internal linking for how this works.
How we work with your developers
Technical SEO succeeds or fails in handover. Our process is designed to make developers’ lives easier.
- Reproduce. We show the problem with evidence and affected URLs.
- Specify. Each ticket states the change, why it matters and how to test it.
- Review. We check staging or pull requests before release.
- Verify. After launch we confirm the effect in Search Console and crawl data.
Technical SEO specialist or full technical SEO consultancy?
Some clients need a technical SEO specialist for one project: a migration, a rendering fix or a speed sprint. Others need an ongoing technical SEO consultancy relationship with monthly reviews and release monitoring. We support both. Single projects are fixed in scope; ongoing support is billed on an agreed monthly allocation, described on our pricing page.
Technical SEO London support for different team sizes
Not every business has an engineering team. For small sites we act as the hands-on technical SEO expert, preparing precise instructions for a freelance developer or your platform’s support. For larger organisations we work with technical SEO consultants on your side, such as engineering leads and product managers, to fit SEO fixes into release cycles. Our technical SEO London clients range from a single web developer to a multi-team platform group.
Some projects suit a freelance technical SEO model, with a defined sprint and a clear end. Others need continuing attention because the site changes weekly. We will recommend whichever is lighter for you.
What a technical SEO sprint delivers
A typical sprint runs for several weeks and ends with fixes live and verified. You receive a prioritised ticket backlog, test evidence from before and after release, and a short summary of what changed in Search Console. If new problems emerge, they are logged with the same level of detail, so nothing depends on memory or goodwill.
When technical SEO is the right first step
Start with technical work when pages are missing from the index, impressions fall after a release, the site is slow, you are migrating or redesigning, or developers and marketers disagree about priorities. If you are unsure, an SEO audit will show whether technical issues are your main constraint or only one factor among several.
Frequently asked questions
What does a technical SEO consultant do?
A technical SEO consultant diagnoses and fixes problems that affect how search engines crawl, render and index a site, then works with developers to implement and verify the changes.
Do you offer technical SEO services in London only?
We are London based, but technical SEO is delivered remotely and works for any UK site. Time zone and language are rarely a barrier.
How is technical SEO different from an SEO audit?
An audit diagnoses widely and prioritises. Technical SEO consulting is the hands-on implementation of technical fixes with your developers over time.
Can you work with our existing developers or agency?
Yes. Most of our technical work is done in partnership with in-house teams or agencies, using tickets and regular reviews.
What tools do you use?
We combine Google Search Console, crawlers, Lighthouse and real-user data, and we interpret the output manually rather than relying on automated scores.
