THE FOUNDATIONUNDER EVERYTHING.

Crawl, render, index and performance engineering for sites where scale is the problem.

Overview

Technical SEO is an engineering discipline. On large sites the limiting factor is rarely content quality — it is how much of the site a crawler can reach, render, understand and choose to keep.

VZN treats a website as a system with budgets: crawl budget, render budget, link equity, performance budget. We measure each, find where they leak, and fix the templates rather than the pages.

Problems we solve
  • /Large sections of the site are crawled but never indexed.
  • /Client-rendered content is invisible to crawlers.
  • /Faceted navigation generates near-infinite low-value URLs.
  • /Migrations lose visibility that never returns.
  • /Core Web Vitals fail on the templates that matter commercially.
Method

How we run it.

  1. 01

    Log and crawl analysis

    Compare what crawlers request with what the site exposes, and where budget is wasted.

  2. 02

    Render audit

    Verify what is present in server HTML versus what depends on client execution.

  3. 03

    Index control

    Canonicals, directives, pagination, parameters and facet rules defined at template level.

  4. 04

    Performance

    Field-data-led work on LCP, INP and CLS on revenue templates first.

  5. 05

    Guardrails

    Monitoring and pre-release checks so regressions are caught before deployment.

Capabilities

What's included.

Technical work is delivered alongside the web team, so fixes ship as template changes in the build pipeline rather than as a document of recommendations someone else has to implement.

  • Log file analysis
  • Crawl budget optimisation
  • JavaScript rendering and SSR review
  • Indexation and canonical architecture
  • Structured data implementation
  • Site migration planning and QA
  • Core Web Vitals engineering
  • Automated technical monitoring
