SEO optimization and analytics tools

SEO, metadata, and structured data

SEO tools cover the on-page signals that move ranking: meta-title and description preview testers (with the truncation rules Google actually uses), Open Graph + Twitter card validators, JSON-LD schema generators for Article / Product / FAQ / HowTo, sitemap.xml builders, robots.txt validators, hreflang tag generators for multi-locale sites. The bias is toward "what does the bot actually see?" rather than ranking-trick territory — the tools surface the same signals that Search Console and Lighthouse audit. Useful when you're launching a content project, doing a pre-deploy SEO sweep, or debugging why a page that should be indexed isn't.
