How to Use Website SEO Audit & Site Health Checker

Search Engine Optimization (SEO) auditing is the foundational practice of assessing a web document against the technical and semantic criteria employed by modern search crawlers like Googlebot and Bingbot. This Website SEO Audit & Site Health Checker executes deterministic, rule-based diagnostic algorithms across Technical SEO (HTTPS encryption, canonical links, robots meta, viewport tags, character encoding, and favicon branding), On-Page SEO (title tag length, meta description snippet boundaries, H1 singularity, heading outline hierarchy, image alt text coverage, and thin content thresholds), Social Open Graph / Twitter cards, and simulated Core Web Vitals (Largest Contentful Paint and Cumulative Layout Shift estimates). Designed with zero AI dependency, every check yields reproducible findings, deterministic Site Health scoring (0–100), and prioritized action items ranked by impact and effort.
