Free SEO Tools
Seven free tools for checking a page's tags, crawl rules, structured data and AI readiness.
Title, meta description, canonical, robots, Open Graph and Twitter Card tags on any URL.
How a link card looks on Facebook, LinkedIn and X, built from the page's tags.
Parse a site's robots.txt and test whether a path is allowed for a crawler.
Check JSON-LD blocks for syntax errors and list the schema.org types found.
Which AI crawlers, such as GPTBot, ClaudeBot and PerplexityBot, robots.txt allows or blocks.
Draft an llms.txt file from a site's home page and sitemap.
Analytics, ad pixel, session replay and chat tags in a page's source.
How These Tools Work
Each tool reads what the server sends, the same first response a crawler gets, and does not run the page's JavaScript. No sign-up is needed. For a scored audit of a whole page with 80+ checks, use the SEO Score API; the free tier allows 2 audits a day.
