JSON-LD Schema Generator
Generate rich snippet structured data for any page.
Fill in a form and get copy-paste JSON-LD for Article, Product, Organization, FAQ, Recipe, BreadcrumbList, LocalBusiness, Event, VideoObject, HowTo and more — validated against Schema.org.
Open tool →SERP Snippet Previewer
See how your page shows up in Google — desktop & mobile.
Paste title, meta description, and URL to see a live Google search-result preview with pixel-width truncation (not character count) for desktop and mobile — exactly how Google renders it.
Open tool →Meta Tag Analyzer
Audit any URL's title, description, OG, canonical, robots.
Paste a URL and get a full tag audit — title length, meta description, canonical, robots, Open Graph, Twitter Card, viewport, theme-color, hreflang, JSON-LD — with issue flags.
Open tool →Open Graph & Twitter Card Preview
See how your URL looks on FB, X, LinkedIn, Slack, Discord.
Paste any URL to see a live preview of how the link unfurls on every major social platform. Catches missing og:image, bad aspect ratios, and broken og:title before you ship.
Open tool →robots.txt Tester
Check if Googlebot can crawl any URL on your site.
Paste your robots.txt and a path — instantly see whether it's Allowed or Blocked for Googlebot, Bingbot, GPTBot, or a custom user-agent, with the matching rule highlighted.
Open tool →Hreflang Tag Generator
Generate correct hreflang markup for multilingual sites.
Pick your language + region pairs and get the full <link rel="alternate" hreflang="..."> block — including x-default, XML sitemap output, and HTTP Link header — ready to paste.
Open tool →Redirect Chain Checker
Follow redirects up to 20 hops and spot SEO issues.
Enter a URL and see every hop in the redirect chain with HTTP status codes — catch redirect loops, 302→301 mixups, HTTPS→HTTP downgrades, and unnecessary hops that bleed link equity.
Open tool →Broken Link Checker
Scan any page for 404s and dead redirects in seconds.
We extract every <a href> on the page and fire concurrent HEAD requests against all of them — real HTTP status codes, anchor text, and CSV export so you can fix broken links in bulk.
Open tool →HTTP Security Headers Scanner
Grade HSTS, CSP, X-Frame-Options, and more.
Scan any URL's response headers and get a letter grade on your security posture — HSTS, CSP, Permissions-Policy, Referrer-Policy, X-Frame-Options, COOP/COEP — plus fixes for every failing check.
Open tool →Want more than one page at a time?
These free tools work on a single URL. When you're ready to monitor an entire site — track every on-page change, alert on ranking drops, run audits across hundreds of pages — our full product covers it in one dashboard.
