How to Do a Complete Technical SEO Audit in 2026

A technical SEO audit is the foundation of any successful SEO campaign. Here is how to run one systematically.

Phase 1: Crawlability

Start by crawling your site with SeoCute Site Audit. Check for pages blocked by robots.txt, noindex meta tags, and crawl errors (4xx, 5xx). Ensure your sitemap is submitted to Google Search Console and contains only canonical, indexable URLs.

Phase 2: Indexation

Compare your crawled page count against Google Search Console indexation. Investigate any large discrepancies. Common causes include thin content pages being de-indexed, parameterised URLs, and duplicate content.

Phase 3: Page Speed

Measure Core Web Vitals for your top landing pages. Focus on LCP (target < 2.5s), CLS (target < 0.1), and FID/INP (target < 200ms). Server response time, render-blocking resources, and unoptimised images are the most common culprits.

Phase 4: Structured Data

Validate your schema markup using Googles Rich Results Test. Errors in structured data can prevent rich snippets from appearing in search results.
