Every SEO tool — free, no sign-up, and nothing to install.
Generate title, description, robots, viewport, canonical and theme-color meta tags from a simple form, with live character counts.

Generate Twitter (X) card meta tags with a live preview — summary, summary_large_image, app and player cards.
Build a valid robots.txt with per-crawler rules, sitemap declaration and crawl-delay. Includes presets for CMS sites and blocking AI crawlers.

Decode percent-encoded URLs and query strings back into readable text, including form-encoded plus signs.
Fetch any live page and audit its meta tags, Open Graph, Twitter cards, headings and images — with a score and prioritised fixes.
Inspect every response header a URL returns, with a security header audit covering HSTS, CSP, X-Frame-Options and more.
Check the HTTP status code any URL returns, with a plain-English explanation of what it means for indexing.
Trace every hop between a URL and its final destination, with the status, timing and type of each redirect in the chain.
Crawl your website and generate an XML sitemap, with depth and page limits, robots.txt support, include and exclude rules, and XML, GZIP, TXT and HTML downloads.

Check a page's canonical tag and follow it to the target — catching canonical chains, redirects and noindexed targets.
Validate an XML sitemap against the protocol — limits, namespace, absolute URLs and lastmod format — with every problem explained.
Test whether any crawler can reach a URL, with the exact rule and line number that decided it. Covers Googlebot, Bingbot, GPTBot and more.

Generate valid JSON-LD structured data for 12 schema types — Article, Product, LocalBusiness, FAQ, Event, Recipe and more — with required fields marked.
