Audits are not the goal. Fixes are. This one-day audit focuses on the highest-leverage issues and skips the trivia.

1. Crawl health

  • Validate robots.txt — no accidental disallow on key sections.
  • Run a crawler (Sitebulb, Screaming Frog) and look at 4xx/5xx volumes.
  • Check sitemap.xml: 200, fresh, references only canonical URLs.

2. Index health

  • Search Console > Indexing > Pages: review reasons for exclusion.
  • Spot-check canonical clusters with site: queries.
  • Audit duplicate content across faceted nav.

3. Rendering

Test with the URL Inspection tool: rendered HTML should contain your primary content and links. Heavy JS-dependent rendering is still the silent killer.

4. Performance

PageSpeed Insights on your top 10 templates. Fix the worst INP regression first — it is almost always a third-party script.

5. Schema

Validate Article, FAQPage, Organization and Product. Fix every error; warnings can wait.

Frequently asked questions

Do I need a paid crawler?
Helpful but not required. Search Console covers 80%.
How often should I audit?
Full audit quarterly. Spot checks monthly.
What about log files?
Useful for high-volume sites. Skip for under 10k pages.
