Key takeaways

  • A technical audit typically starts with crawlability: checking robots.txt, server responses, and blocked resources that may prevent search engines from accessing pages.
  • A separate indexation review is needed to confirm which pages are actually indexed and whether important URLs are excluded by noindex, canonical tags, or other directives.
  • XML sitemaps should exist, be current, and contain only URLs you want indexed; they should also be submitted and monitored in Google Search Console.

For SEO practitioners, it helps surface issues that can stop Google from crawling or indexing important pages, which is often a prerequisite for ranking improvements. It also creates a repeatable workflow for monitoring fixes, prioritizing errors, and tracking technical regressions over time.
