SEO Inspector 作者： Alanas

SEO Inspector reads the page you're on and shows the SEO data developers actually need.

What it does:
Click the toolbar icon. The audit runs on the current tab and renders title, meta description, canonical, robots, headings, OG and Twitter cards, JSON-LD, image alts, link inventory, hreflang, and conflict flags. Hit the Copy button (or Cmd+Shift+C / Ctrl+Shift+C) and the entire audit lands on your clipboard as JSON.

Features:
- Live SERP preview with pixel-width title and description.
- H1-H6 visual outline. Flags missing or duplicate H1.
- Canonical URL with cross-domain warning.
- Robots meta with unmissable noindex badge.
- Open Graph and Twitter card preview, including the image.
- JSON-LD pretty-print with per-block copy.
- Image alt audit: missing, decorative, lazy-loaded counts.
- Link inventory with nofollow overlay on the page.
- Mobile viewport check.
- Hreflang validation with x-default check.
- Canonical and robots conflict detector.
- Copy the whole audit as JSON.
