Technical SEO audit checklist
- 32 checkpoints, from crawling to Core Web Vitals
- Google’s official thresholds, sourced and dated
- A grid to prioritize by impact and effort
What the checklist covers
The 32 points are split into eight steps, in the order an audit is carried out:
| Step | What you check |
|---|---|
| 1. Before you start | Access gathered, site history, no manual action, staging site not indexed |
| 2. Crawling | robots.txt, blocked resources, crawl errors |
| 3. Indexing | Gap between crawled and indexed pages, canonicals, sitemap |
| 4. Architecture and internal linking | Click depth, orphan pages, breadcrumbs |
| 5. HTTP codes and redirects | 4xx and 5xx errors, 302 redirects, redirect chains |
| 6. Performance | LCP, INP and CLS at the 75th percentile, image weight |
| 7. JavaScript rendering and mobile | Content present in the raw HTML, mobile and desktop parity |
| 8. Reporting | Findings backed by data, prioritized actions, roadmap |
The performance thresholds are the ones Google publishes on web.dev, “Web Vitals” page, accessed on September 24, 2026. A page is rated good with an LCP of 2.5 s or less, an INP of 200 ms or less and a CLS of 0.1 or less. These values are read at the 75th percentile of page loads.
How do you use it?
- Print or open the PDF next to Search Console and your crawler.
- Tick each point, noting the data that proves it: export, screenshot, date.
- Rank the non-compliant points by impact and effort, with the grid from the last step.
- Refer to the guide for each point that raises a question.
The full method, point by point, is detailed in the technical SEO audit guide. To place the technical audit among the other audits (content, link building, semantic), read the SEO audit guide.
