Technical SEO Audit

A technical SEO audit is a systematic review of a website's infrastructure to identify issues that prevent search engines from crawling and indexing pages. Oddtusk audits site architecture, rendering, and crawl efficiency to remove barriers to ranking.

A technical SEO audit uncovers the infrastructure issues that silently hold back your rankings. We diagnose crawlability gaps, indexation problems, Core Web Vitals failures, broken structured data, and site architecture inefficiencies so every page has the best possible chance of ranking. Sites that combine a clean technical foundation with semantic SEO and topical authority mapping see compounding organic growth.

What a Technical SEO Audit Covers

Our audit methodology is built on Screaming Frog crawl data, Google Search Console diagnostics, and manual code-level inspection. We examine six interconnected layers of technical health that determine whether search engines can efficiently discover, render, and rank your content.

Crawlability and Indexation

We analyse your robots.txt directives, XML sitemaps, canonical tags, and internal linking topology to ensure Googlebot can reach every important page without wasting crawl budget on thin, duplicate, or orphaned URLs. Pages that are crawled but not indexed receive individual diagnosis.

Core Web Vitals and Page Speed

Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift are measured at the URL level. We trace each bottleneck to its root cause, whether that is unoptimised images, render-blocking JavaScript, layout shifts from lazy-loaded elements, or server response time.

Structured Data Validation

Every JSON-LD block is parsed and validated against the schema.org specification. We check for missing required properties, deprecated types, incorrect nesting, and ensure rich-result eligibility for breadcrumbs, FAQs, products, and organisation markup.

Site Architecture and Internal Linking

Click depth, link equity distribution, and topical siloing are mapped to identify orphaned pages, over-linked utility pages, and broken internal link paths. The goal is a flat, semantically coherent architecture where every page is reachable within three clicks from the homepage.

Redirect Chains and HTTP Status Codes

We audit for redirect chains longer than two hops, redirect loops, soft 404s, and inconsistent trailing-slash behaviour. Every non-200 response is catalogued with a recommended fix and assigned priority based on traffic impact.

Security, Accessibility, and Rendering

HTTPS enforcement, mixed-content warnings, hreflang implementation, and JavaScript rendering issues are reviewed. If your site relies on client-side rendering, we verify that Googlebot can access the fully rendered DOM and that critical content is not hidden behind JavaScript execution.
