SEO Titan is a free, client‑side SEO audit tool that analyses your page HTML directly in your browser. No data is ever sent to a server. It checks 10 critical modules: title tag, meta tags (description, canonical, robots), heading hierarchy (H1‑H6), images & alt attributes, Open Graph, Schema.org JSON‑LD, internal/external links, content readability & keyword density, mobile & Core Web Vitals hints, and security (mixed content, insecure forms).
