Free SEO Audit Tool — Find What's Hurting Your Rankings
Most sites have SEO issues they don't know about. Missing meta descriptions, broken structured data, pages Google can't crawl, slow load times killing mobile rankings.
SiteAudit AI checks all of it in one pass and tells you what to fix first.
What the SEO audit checks
- Meta titles and descriptions (missing, duplicate, too long, too short)
- Heading hierarchy (H1 presence, logical H2/H3 structure)
- Structured data / JSON-LD (Organization, FAQ, Breadcrumb, Article)
- Indexability (noindex tags, canonical issues, robots.txt blocks)
- Crawlability (broken internal links, orphan pages)
- Core Web Vitals (LCP, CLS, INP)
- Mobile-friendliness
- Image optimization (alt text, formats, compression)
- HTTPS and security headers
