Technical SEO

Everything you publish depends on whether machines can fetch it, render it, understand it and keep it. Technical SEO makes sure nothing is lost between your codebase and the systems that read it.

Serves the Structure, Prove stages of the Method.

What it is

Technical problems rarely announce themselves. They show up as pages that never rank, content that is indexed months late, and measurement that quietly undercounts. We find them at the root, in the architecture, the rendering path and the release process, and fix them so they stay fixed.

When you need it

  • Large or JavaScript-heavy sites where crawl budget, rendering and indexation are poorly understood.
  • Migrations, replatforms and redesigns that must not lose organic demand.
  • Slow pages and layout instability that cost both users and visibility.
  • Structured data, canonicalisation and internationalisation implemented inconsistently across templates.

How we approach it

  1. Full crawl and log-file analysis to see the site as crawlers see it, not as the CMS presents it.
  2. Rendering audit for JavaScript-dependent content, with a reproducible test for every template.
  3. Indexation strategy: what should be indexed, what should not, and how the signals say so consistently.
  4. Performance and Core Web Vitals engineering with the development team, in their tooling and release process.
  5. Migration planning and post-launch verification for replatforms and redesigns.

What we deliver

  • Technical audit with prioritised backlog and owner per item
  • Rendering and indexation test suite
  • Structured-data and internationalisation specification
  • Migration plan, redirect map and verification report

How we measure it

  • Indexation coverage and time-to-index for new content
  • Crawl efficiency: share of crawl spent on valuable URLs
  • Core Web Vitals at the 75th percentile, by template

Every figure we report carries a method note and a source. Where a result cannot be attributed with confidence, we say so.

    Log File Analysis for SEO in 2026

    Search Console shows you a summary of how Google crawls your site. Your server logs show every request, from Googlebot and from the AI crawlers. This guide covers how to get the right logs, how to tell real bots from fakes, the six questions worth answering, and what to fix first, checked against Google's, OpenAI's and Anthropic's documentation on 2 November 2026.

    Schema Markup That Still Matters in 2026

    Google has retired more rich results in the last three years than it has launched, FAQ included as of May 2026. Most schema advice online predates that. This guide lists what is gone, what still earns something, and the small set of markup worth maintaining on a normal business site, checked against Google's own documentation on 22 October 2026.

    AI Crawlers: What to Allow, What to Block

    Every AI provider now runs at least two bots, and they do different jobs. One feeds training. One feeds the answers your buyers read. Block the wrong one and you disappear from ChatGPT search or Claude without noticing. Here is each bot, what it does, and a robots.txt that says what you mean.

  • Guide
    Internal Linking as a System

    Internal links are the cheapest ranking lever most sites never pull on purpose. This guide turns them from a chore into a system: three link roles, a hub-and-spoke map you can draw in an afternoon, anchor rules, a four-check audit, and a routine that keeps it alive after launch.

  • Guide
    Core Web Vitals: What to Fix First

    Three metrics, three thresholds, and a long list of things people fix that never move them. This guide gives you the order that works: which number to read, which template to start with, the usual cause behind each failing metric, and what to stop spending time on.

  • Insight
    The noindex that shipped with a release

    A short note from live work. The most expensive technical SEO fault we keep meeting is not decay. It is a single tag that rides along with a normal deployment, and nobody looks for it because nothing looks broken.

    The Technical SEO Audit Checklist for 2026

    A prioritised, testable checklist for auditing crawlability, indexation, rendering, architecture, performance and structured data, with what to fix first, how to prove each fix, and how often to repeat it.

    The Architecture of Organic Growth

    Organic growth is not a content problem or a ranking problem. It is an architectural problem: the relationship between business model, structure, intent, content, technology, authority and measurement.

    Technical Debt and Organic Growth

    How rendering, crawlability, indexation, URL architecture, redirects, duplication, internal linking, performance, structured data, CMS limits and migrations create long-term organic constraints, and what they cost commercially.
