Technical SEO Agency

Technical SEO Services that fix the foundations so everything else works.

Crawl issues, JavaScript-rendered pages, slow LCP, broken schema, bloated XML sitemaps — the boring engineering work that decides whether content and links actually move the needle.

What is Technical SEO Services?

Technical SEO Services — explained without the jargon.

Most SEO programmes plateau because the underlying site is technically broken. Pages aren't indexed, JavaScript blocks rendering, Core Web Vitals fail, schema is malformed, the same product is at four different URLs. Our technical SEO team is made up of engineers — people who can read your codebase, write the spec, and verify the PR. We work alongside in-house dev teams as deeply or as lightly as you need.

Why it matters

Three things most teams get wrong about technical seo services.

01

No technical, no rankings

You can produce world-class content and earn the best links on earth. If Google can't crawl, render or index it, none of it ranks.

02

Core Web Vitals are a ranking factor

Google uses LCP, INP and CLS as ranking signals. Sites that fail them lose visibility — and the fix is engineering, not copywriting.

03

Most audits are useless

A 200-page PDF with no prioritisation, no implementation plan and no engineer attached. We deliver fixable spec, not theatre.

What's included

Everything we ship under Technical SEO Services.

01

Crawl & indexation audit

Screaming Frog + Sitebulb deep crawl, log file analysis, indexation gap analysis against actual ranking pages.

02

Core Web Vitals optimisation

LCP under 1.5s, INP under 200ms, CLS under 0.1 — measured at the 75th percentile from real user data.

03

JavaScript SEO

Rendering checks via mobile-friendly test, prerender setup if needed, hydration audit for React/Next/Vue sites.

04

Structured data

Schema.org markup for Organisation, Product, Article, FAQ, HowTo, Event, Recipe, BreadcrumbList — whichever your content demands.

05

Sitemap & robots engineering

Clean XML sitemaps split by template, robots.txt rules that actually align with what Google should crawl.

06

Migration support

Pre-migration URL mapping, 301 strategy, post-launch monitoring — for replatforms, mergers and domain changes.

Technical SEO Services · Case Study

SaaS replatform: PageSpeed 38 → 98, indexation 47% → 99%

A B2B SaaS replatformed from a creaky Drupal stack onto Next.js. Pre-launch their pages were averaging LCP of 4.2s and 53% of URLs were missing from Google's index. We mapped 2,140 URLs, wrote the 301 strategy, audited the new build pre-launch, fixed render-blocking issues in the App Router, and added structured data across every template. Three months post-launch, signups were up 71% and indexed pages climbed from 47% to 99% of the sitemap.

JavaScript SEO depth

Migration safety

Replatforms and domain changes are our speciality. Full URL mapping, 301 strategy, 60-day post-launch monitoring.

FAQ

Questions you were going to ask anyway.

Can you work alongside our in-house dev team?
Yes — that's how most engagements run. We write tickets, your team ships. Or we ship together. We adapt to your workflow (Jira, Linear, GitHub Issues) and PR review cadence.
What's the timeline for a technical audit?
A full 200-point audit takes 1-2 weeks depending on site size. Sites under 10K URLs ship in a week. Large enterprise sites (100K+ URLs) take 2-3 weeks because log file analysis at that scale is non-trivial.
Do you handle international hreflang setups?
Yes — see our International SEO Services page for the full programme. Hreflang implementation, audit, and ongoing monitoring is a sub-discipline of technical SEO that we run regularly.
What if my site uses heavy JavaScript?
No problem. We audit rendering with Google's mobile-friendly test and Chrome DevTools, evaluate whether prerendering or SSR is needed, and audit hydration if you're on React/Next.
How do you measure success?
Core Web Vitals (CrUX 75p), indexation coverage, organic clicks from GSC, and ranking lift on target keyword clusters. We baseline before sprint one and report against that baseline monthly.
