In today's search environment, rankings are no longer driven by keywords alone. Google's AI systems evaluate technical health, content quality, user engagement, and entity relevance. A comprehensive SEO audit must track the right KPIs to improve both traditional rankings and AI-driven visibility.
Whether you're delivering professional SEO audit services or conducting an internal website audit, these KPIs directly influence performance.
1. Website Health Score
A foundational metric in any site audit, website health score reflects the percentage of technical SEO issues resolved.
What it includes:
- Broken links
- Redirect chains
- Crawl errors
- Duplicate content
- HTTPS issues
Why it matters: Search engines prioritize technically stable websites. A low health score can limit crawl efficiency and ranking potential.
2. Crawlability & Indexation Rate
If search engines cannot crawl or index your pages, rankings are impossible.
Key metrics:
- Indexed vs. submitted URLs
- Orphan pages
- Crawl depth
- Noindex errors
Impact on AI visibility: AI-powered search systems rely on clean indexing signals and structured content.
3. Core Web Vitals (INP, LCP, CLS)
User experience directly affects rankings.
Core KPIs:
- Largest Contentful Paint (LCP)
- Interaction to Next Paint (INP)
- Cumulative Layout Shift (CLS)
These metrics are essential in every modern website audit.
4. Organic Traffic Growth

These metrics reflect real user satisfaction.
9. Structured Data & Schema Coverage
Schema markup improves eligibility for rich results and AI summaries.
Measure:

A complete site audit should include schema validation.
10. Local SEO Performance (If Applicable)
For local businesses, local ranking KPIs matter.
Track:

Local SEO metrics are essential in professional SEO audit services.
