Free SEO Audit
Runs 442 checks across 20 categories — on-page SEO, security headers, Core Web Vitals, crawlability, content quality, EU compliance, AI / GEO citability, and more. Produces a 0–100 health score with prioritised findings.
Run a free audit →Meta Description Checker
Paste a meta description and see its character count, byte count, and estimated SERP pixel width against the desktop and mobile truncation points.
Check a description →robots.txt Tester
Fetch any site's robots.txt and test whether a specific URL path is allowed for a given crawler. Shows the matched rule, sitemap declarations, and the raw file.
Test a path →Redirect Chain Checker
Trace every hop of an HTTP redirect chain. See status codes, redirect types (301/302/303/307/308), meta-refresh, loops, and timing per hop.
Trace a URL →Sitemap Checker
Validate sitemap.xml structure. Catches malformed XML, future-dated lastmod values, missing or invalid <loc> URLs, and Google's 50,000-URL / 50 MB hard limits.
Check a sitemap →robots.txt Checker
Test whether a path is allowed for Googlebot, Bingbot, GPTBot, ClaudeBot, PerplexityBot, or any user-agent. Catches the most common cause of “Google stopped ranking us” — and AI search opt-outs.
Check rules →Open Graph & Twitter Card Preview
Paste a URL and see exactly how Twitter, LinkedIn, and Facebook will render the link preview. Surfaces every common mistake — missing og:image, wrong aspect ratio, twitter:card mismatches, and image content-type bugs.
Schema.org & JSON-LD Validator
Paste JSON-LD or a URL. Per-block, per-type required-field check for Product, Article, Recipe, FAQPage, HowTo, JobPosting, LocalBusiness, and 16 more types — the same rules Google's rich-results test applies.
Validate schema →Hreflang Checker
Paste a URL. We probe every alternate language URL and verify it links back in its own hreflang set — the reciprocity check most validators skip. Also catches missing self-reference, missing x-default, invalid BCP 47 codes, and broken alternates.
Check hreflang →Security Headers Checker
Paste a URL. Get an A–F grade plus per-header fix guidance for Content-Security-Policy, HSTS, X-Frame-Options, Referrer-Policy, Permissions-Policy, and Cross-Origin-* headers. Recognises the modern strict-dynamic CSP upgrade most checkers get wrong.
Grade headers →llms.txt Validator & AI Crawler Check
Paste a URL. Validates /llms.txt against the llmstxt.org spec AND cross-checks robots.txt for whether GPTBot, ClaudeBot, PerplexityBot, and the other major AI crawlers are blocked — the silent reason most well-formed llms.txt files do nothing.
