Free SEO Tools
Audit and fix your on-page SEO from end to end. Paste a URL to analyze its meta tags and map its H1–H6 heading outline, preview how the page will look in Google search results, and check keyword density with proper Thai word segmentation. Then generate the markup you need — robots.txt, JSON-LD schema, meta and Open Graph tags, and hreflang for multilingual sites — and test your robots.txt rules to confirm Googlebot can reach the URLs you care about. Copy, paste, no account needed.
