Technical SEO services
Technical SEO is the difference between a website search engines can use and one they struggle with. It is usually the cheapest growth available, because nothing else works until it is right.
Technical SEO is the work of making sure search engines can crawl, render, index and understand a website quickly and reliably.
It covers site architecture, status codes, canonicalisation, sitemaps, robots directives, JavaScript rendering, page speed, Core Web Vitals, structured data and mobile usability.
Symptoms of a technical problem
- Pages that never appear in Google despite being published months ago.
- Traffic that fell off a cliff after a redesign, replatform or URL change.
- Thousands of near-identical URLs generated by filters, parameters or pagination.
- A site that scores badly on mobile and loses visitors before the content renders.
Who this is for
- Sites that have been through a migration or redesign
- Ecommerce stores with large catalogues and faceted navigation
- JavaScript-heavy sites where content may not be rendering for crawlers
- Any business whose rankings plateaued despite good content
What a technical audit covers
- Crawling and crawl budget
- Indexing and index bloat
- XML sitemaps and robots.txt
- Canonical tags and duplicate content
- HTTP status codes and redirect chains
- Site architecture and click depth
- Internal linking
- JavaScript rendering
- Core Web Vitals and page speed
- Mobile usability
- Structured data and JSON-LD
- HTTPS, security and hreflang where relevant

Search engine optimisation is the work of making your website the obvious answer to the searches your customers already make. We do it in a deliberate order and explain every step.
A website is a commercial tool, not a brochure. We build sites that load fast, read clearly, rank properly and make the next step obvious.
Most ecommerce SEO problems are structural. Fix how the catalogue is organised and crawled, and the content work starts paying much faster.
WordPress runs a large share of the web for good reasons. Most of the problems blamed on it come from bloated themes, plugin sprawl and cheap hosting.
Technical SEO questions
Do I need technical SEO?
If pages are missing from Google, the site is slow on mobile, or rankings dropped after a change to the website, then yes. If none of those are true, a lighter health check is usually enough.
What is the difference between technical SEO and on-page SEO?
Technical SEO is about whether search engines can access and understand the site. On-page SEO is about whether a specific page deserves to rank for a specific search. Both matter, in that order.
How often should a technical audit be done?
A full audit once a year for most sites, plus a check before and after any redesign, migration or platform change. Large ecommerce sites benefit from continuous monitoring.
Will fixing Core Web Vitals improve my rankings?
It can help, particularly where you are close to competitors, and it reliably improves conversion. It will not rescue a page that does not answer the search.
Can you work with our developers?
Yes. We regularly deliver specifications and tickets that in-house teams implement, then verify the result.
Does WordPress cause technical SEO problems?
WordPress itself is fine. Problems usually come from plugin conflicts, bloated themes, poor hosting and accumulated redirects. See WordPress development.
