Site Audit

A technical-SEO crawler that scans your site for 140+ issue types and returns a 0-100 Site Health score with issues ranked Errors / Warnings / Notices. Fix your own foundation before chasing rankings: crawlability, broken links, duplicate content, Core Web Vitals, HTTPS, and structured-data problems all surface here.

Syntax

semrush

Site Audit → configure crawl (scope, limit, user-agent) → Site Health score → Errors > Warnings > Notices

Example

semrush

// Triage order after a crawl
Errors first (break indexing/UX):
  - 4xx / 5xx pages, broken internal links
  - pages blocked in robots.txt you WANT indexed
  - duplicate title tags / meta descriptions

Then Warnings:
  - slow pages / Core Web Vitals
  - missing alt text, low text-to-HTML ratio

Thematic reports:
  Crawlability · HTTPS · Core Web Vitals ·
  Internal Linking · Markup (schema)

// Re-crawl after fixes to confirm Site Health climbs.
