Technical SEO

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.

Technical SEO

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.

Technical SEO

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.

Technical SEO + AI

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 →
Social / Sharing

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.

Structured data

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.

International SEO

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

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 →
AI search

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.
