Technical SEO Audit
Every Infrastructure Issue Found and Prioritised
A deep-dive audit focused entirely on the technical foundation of your website. Crawlability, indexation, Core Web Vitals, security headers, redirect chains, canonical tags, robots.txt, XML sitemaps, structured data, and JavaScript rendering, 40 checks across 12 categories.
Every finding scored by severity and business impact. An AI-generated remediation plan tells your team what to fix first. Works the same for 20-page brochure sites or 20,000-page enterprise sites.

Credentials
Experience
I built the BrightIQ audit engine, 40 deterministic technical checks, Chromium-based rendering, and a site architecture graph with PageRank distribution. When you order a Technical SEO Audit, the same person who wrote the rules reads the output and writes the remediation plan. No handoffs, no junior analysts.
Why this matters
- ✓ 40 checks written and maintained by one person, I know exactly what fires, why it fires, and what to do about it
- ✓ Chromium-based crawling sees JavaScript-rendered content exactly as Googlebot does, no simplified HTML-only view
- ✓ Every finding is severity-weighted by business impact, not just flagged as a pass/fail

Frequently Asked Questions
What does a technical SEO audit check?
BrightIQ runs 40 deterministic checks across 12 categories: crawlability, indexation, Core Web Vitals, security headers, redirect chains, canonical tags, robots.txt, XML sitemaps, structured data, mobile rendering, internal linking, and JavaScript handling. Every check returns pass/fail/warning with severity weighting.
What do I receive from the technical audit?
Three deliverables: a branded audit PDF (severity-scored findings, site architecture visualisation, Core Web Vitals assessment, prioritised remediation plan), a combined issues spreadsheet with dev action tabs, and ready-to-deploy schema JSON-LD files for all flagged pages.
How long does delivery take?
24 hours from receiving access. The audit engine runs a full-browser technical crawl via Crawl4AI, applies 40 checks, and generates a prioritised remediation plan. Turnaround is the same for 20-page brochure sites and 20,000-page enterprise sites.
Does the audit work on JavaScript-heavy sites?
Yes. Crawl4AI launches a real Chromium browser, it renders JavaScript, captures dynamically loaded content, and sees the site exactly as Googlebot does. SPAs, React sites, and page-builder output are all captured accurately. The crawl includes a rendering comparison so you can see what Google sees vs what the raw HTML contains.
Is the report white-label ready?
Yes. The branded audit PDF is delivered with your agency's logo, colours, and contact details. Your client sees your brand, not BrightIQ's. Agencies using the technical audit as part of their onboarding process can request custom report templates.
How is this different from a Screaming Frog crawl?
A crawler collects data. This audit interprets it. BrightIQ runs 40 deterministic checks, weights findings by severity and business impact, maps the site architecture graph with PageRank distribution, and delivers a prioritised remediation plan. The issues spreadsheet gives your dev team the raw data. The report gives decision-makers the story.
