Back to toolSEO Audit
Enter a site URL and get a unified report: meta tags, Open Graph, structured data, HTTP headers, robots.txt, sitemap, and PWA manifest — in a single request.
Unlike most tools in this lab, this audit fetches the site from the server (not your browser), because third-party HTML is usually blocked by CORS.
How to use
- Paste the URL (with or without
https://). - Click analyze.
- Browse the report tabs (summary, checklist, meta, and more).
You can also share the tool URL with the analyzed page as a query parameter.
What the audit collects
| Area | Contents |
|---|---|
| Page | Final URL (after redirects), HTTP status, content-type |
| Meta | title, description, canonical, robots, Open Graph, Twitter Cards |
| JSON-LD | structured-data blocks found in the HTML |
| Headers | raw headers plus common security checks |
| Crawl | robots.txt and sitemap.xml (at the root or via a Sitemap: declaration) |
| Manifest | Web App Manifest (PWA), fields, and icons |
| Checklist | pass / fail / warn checks with suggestions |
Preview images (when present) go through a proxy on this site, so they do not depend on hotlinking the analyzed domain.
Scope: technical metadata checker
This tool is a fast technical checklist for metadata and public files — not a full-site crawler and not a market “SEO audit” suite (Ahrefs, Screaming Frog, and similar).
What this tool does not replace
- Google Search Console, Bing Webmaster Tools, or ranking tools
- A full site crawl (only the given URL plus related robots/sitemap/manifest)
- Editorial content audits, backlinks, or field Core Web Vitals
- A guarantee of indexing or search ranking
Frequently asked questions
Why doesn’t the fetch run in my browser?
Because most sites block cross-origin reads (CORS). A server-side fetch avoids that, with SSRF protections.
Are results cached?
Yes, for about 5 minutes (server and client) so the same URL is not re-fetched on every click.
Privacy and fetch safety
- The server fetches the URL with SSRF protections (it will not open private/local targets improperly).
- Do not request analysis of URLs you are not authorized to inspect.
Technology used
- node-html-parser to read the HTML and extract meta tags, JSON-LD, and the like.
