Free SEO tools for developers
These free SEO tools help you ship correct HTML snippets and structured data: meta tag generator, JSON-LD, XML sitemap, robots.txt, Open Graph, and canonical URLs. They match searches like “free SEO tools” and “SEO optimization tools” in the technical sense—metadata and crawl hints—not full-site audits or domain authority scores.
