关于此扩展
Most SEO tools make you paste a URL into a web app and wait. Scoped SEO works differently. Open any webpage, click the extension, and get a complete on-page SEO audit in under a second — right inside Firefox. Everything runs locally. Nothing leaves your device. No account. No subscription. No limits.
What Scoped SEO analyzes:
Content & On-Page Elements
Title tag length with pixel-width estimate, meta description, canonical tag, robots meta, X-Robots-Tag, language attribute, and word count — all with clear pass/fail status and actionable guidance.
Links
Full internal and external link audit with anchor text, follow/nofollow/UGC/sponsored attributes, duplicate detection, new-tab flags, and one-click CSV export. Filter by link type and search across hundreds of links instantly.
Images
Alt text coverage, file size, pixel dimensions, next-gen format detection (flags JPG/PNG, suggests WebP/AVIF), layout shift warnings for images missing width/height attributes, and hover-to-enlarge thumbnail previews.
Schema / Structured Data
Detects all JSON-LD blocks with syntax highlighting, validates against required properties for 15+ schema types (Article, Product, FAQPage, Recipe, Event, and more), per-block Copy JSON buttons, and direct links to Google's Rich Results Test pre-loaded with your URL.
Hreflang
Lists every hreflang alternate tag with validation — flags missing x-default, duplicate language codes, and malformed values.
Speed & Core Web Vitals
Real LCP, CLS, and INP measured live from the actual page load using the browser's own Performance API. Includes a slowest-resources waterfall and optimization suggestions.
Tech Stack Detection
Detects the CMS, JavaScript frameworks, analytics platforms, and ad tools running on any page.
GEO / AI Visibility Score
19-point AI optimization score checking AI crawler access in robots.txt (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, OAI-SearchBot, Applebot-Extended, and more), schema coverage, content structure, author signals, freshness indicators, and llms.txt.
Social Preview
See exactly how your page will appear when shared on Facebook, LinkedIn, X (Twitter), and in Google search — desktop and mobile previews side by side.
Why Scoped SEO is different:
✓ 100% local — your page content never leaves your browser
✓ Results in under a second on the live page, not a cached snapshot
✓ No account, no paywall, no setup required
✓ Clean, focused interface built for real SEO work
Privacy: Uses only activeTab, scripting, and storage permissions. No background activity. No data collection of any kind. Storage is used only to remember which panel you last had open — cleared automatically when your session ends.
