What the Free SEO Lighthouse Audit Checks
Document Crawlability
Checks for robots meta tags, X-Robots-Tag headers, and whether the page is blocked by robots.txt — confirming Googlebot can actually access and process the URL.
Mobile SEO Signals
Verifies a viewport meta tag exists, font sizes are at least 12px for legibility, and tap targets (buttons, links) are at least 48x48px — critical for mobile-first indexing.
Link Architecture
Checks that all links have descriptive anchor text (not just 'click here'), external links use rel=noopener, and href attributes contain valid URLs rather than JavaScript handlers.
Structured Data
Validates presence of JSON-LD or Microdata structured data and tests it for schema.org conformity — a prerequisite for rich results in Google Search.
