Technical SEO audit checklist for growth teams

Technical issues can cap rankings even when content quality is strong. Use this checklist to remove blockers that hurt discoverability and conversions.

1) Crawlability and sitemap hygiene

  1. Confirm robots.txt allows critical pages and references your sitemap.
  2. Keep sitemap URLs canonical and indexable only.
  3. Remove redirected or duplicate URLs from the sitemap.

2) Indexation and canonical checks

  1. Use self-referencing canonicals on unique pages.
  2. Fix noindex tags on revenue pages that should rank.
  3. Eliminate redirect chains and conflicting canonical signals.

3) Performance and Core Web Vitals

  1. Improve LCP by reducing render-blocking CSS/JS and image payload.
  2. Reduce INP by trimming long JavaScript tasks.
  3. Keep CLS low with stable layout boxes for media and embeds.

4) Structured data and entity clarity

  1. Implement valid JSON-LD for organization and core page types.
  2. Add FAQ schema only where visible FAQ content exists.
  3. Validate structured data and monitor errors after deployment.

If you want this translated into a page-by-page fix queue, run a SignalLift audit and prioritize changes by impact.
