What meta tags does it extract?

SmartScan extracts title, meta description, canonical URL, robots directives, hreflang attributes, all Open Graph tags (og:title, og:description, og:image, og:type, etc.), Twitter card tags, and all JSON-LD structured data blocks.

Does it work on JavaScript-rendered pages?

Yes. Switch to Dynamic rendering mode to fully render JavaScript before extracting — important for SPAs where meta tags are injected by React, Vue, or Next.js.

Can I export the meta tags?

Yes — results are available as a structured JSON file inside the downloadable ZIP archive. Includes all meta tag groups in a clean, readable format.

Is this useful for SEO audits?

Absolutely. You can quickly check if a page has a canonical, if og:image is set, whether robots is set to noindex, and if structured data is correctly implemented — all in one scan.

Yes — SmartScan is free. Register for 1,000 scans/month. No credit card required.
