  SEO Tools PRO — Instant On-Page SEO Audit + Live Google Rank Tracker, Right In Your Browser.
  
  The fastest way to audit any page's SEO and track Google rankings — free, unlimited, no login. Built for professionals who want answers, not a SaaS bill.
  
  One click reveals everything that matters: title, meta, schema.org markup, Core Web Vitals, link health, image audit, keyword density, and a 100-point SEO score. Plus a live Keyword Rank Tracker that measures your TRUE organic position on 20+ Google domains — separated from the visual position that counts ads, AI Overview, and featured snippets above you.
  
  ▸ WHY TEAMS PICK SEO TOOLS PRO
  
  • Free forever. No trial, no upsell, no upgrade prompts.
  • Works in any country — 20 Google search domains, 8 native UI languages.
  • Honest numbers. Organic position is reported separately from visual position.
  • Privacy-first. Everything runs locally. No tracking by default.
  • Lightweight. ~150 KB. Loads in milliseconds. Zero third-party libraries.
  
  ▸ LIVE GOOGLE RANK TRACKER (FLAGSHIP)
  
  Enter a keyword + target domain. We open Google in a new tab and our content script reads the live SERP to compute:
  
  • Your real ORGANIC position
  • Your VISUAL position (counts ads, featured snippets, AI Overview, PAA, knowledge panel, image / video / news packs above you)
  • Multi-occurrence warning when your domain ranks more than once
  • AI Overview citation detection in 8 languages — knows when Google's AI cites your domain
  • Visual overlay: #N badge next to every organic result, 🎯 sticker on your domain, sticky summary bar
  
  Supports 20 Google domains: .com, .com.vn, .co.uk, .de, .fr, .es, .it, .com.au, .ca, .co.jp, .co.kr, .com.br, .com.mx, .com.tr, .com.sg, .com.hk, .co.in, .com.tw, .pl, .nl.
  
  Multi-page accumulation: scroll to page 2, 3, 4 — we merge with a 30-minute freshness window. History of 50 checks with one-click re-scan.
  
  ▸ ON-PAGE SEO AUDIT
  
  100-Point SEO Score — weighted across 16 factors with pass / warn / fail and an animated gauge. Click any quickstat to filter to just Passed, Warnings, or Failed.
  
  Schema.org Reader — parses JSON-LD (including @graph and root arrays from Yoast / RankMath / Schema App), Microdata (itemscope / itemtype / itemprop), and RDFa Lite (typeof / property). Matches Schema.org Validator's entity count. Tree view shows nested entities (HowToStep × 4, Product Offer, Article author + publisher + ImageObject). One-click jump to Google Rich Results Test.
  
  Core Web Vitals — LCP, CLS, INP measured with web.dev's official thresholds via PerformanceObserver. No third-party services.
  
  Meta & Social Preview — pixel-accurate Open Graph and Twitter Card previews exactly as your link will look when shared. Title, meta description, canonical, robots, hreflang.
  
  Link Inspector — every row shows anchor + URL. Click to expand: full URL, raw href, title, rel breakdown (nofollow / sponsored / ugc / noopener / noreferrer), target. Detects tabnabbing (target="_blank" without rel="noopener"). Filter by internal / external / nofollow / warnings.
  
  Plus: Heading H1–H6 tree, image audit (alt / width / height / lazy-loading), readability (Flesch + reading time), keyword density (1- to 6-gram, 5 language stop-word lists auto-selected), technical health (HTTPS, viewport, robots.txt + sitemap.xml probe, mixed-content detector), page performance (TTFB / FCP / heaviest resources).
  
  ▸ EXPORT & WORKFLOW
  
  • Export as JSON, CSV (formula-injection-protected for Excel safety), or self-contained HTML — ready for client deliverables
  • 8 native UI languages: English, Vietnamese, German, French, Spanish, Japanese, Korean, Simplified Chinese
  • Light / Dark / Auto theme — syncs with your OS in real time
  • WCAG 2.2 AA accessibility — full ARIA tab pattern, keyboard nav, focus-visible, prefers-reduced-motion, forced-colors
  • 10-tab dashboard in a 720 × 540 (4:3) popup that respects your eyes
  
  ▸ WHO IT'S FOR
  
  • SEO specialists running dozens of on-page audits and rank checks per day
  • Agencies producing client-facing audit + ranking reports
  • Content writers checking meta, headings, and keyword balance before publish
  • Web developers validating schema.org / JSON-LD / Microdata / RDFa output
  • Vietnamese SEO consultants needing google.com.vn rank tracking with AI Overview detection
  • Small-business owners who want a professional second opinion on their own site
  
  ▸ PRIVACY — HONEST DISCLOSURE
  
  No account. No login. No profile. No tracking by default.
  
  What runs locally only:
  • On-page audit — reads the active tab when you click the icon
  • Rank tracker — runs only on Google search pages you visit
  • Rank history (50 entries) + affiliate click counters — stored on your device in chrome.storage; never transmitted
  
  Optional diagnostic telemetry (OFF by default):
  If you enable it in Settings, the extension logs anonymous scan-complete events (version, browser kind, sanitized score, counts) to a local 200-event ring buffer. URLs, hostnames, page contents auto-redacted. Optional self-hosted beacon endpoint — if blank, the log stays purely on your machine.
  
  ▸ AFFILIATE DISCLOSURE
  
  The footer's Smart Tool Recommendations slot surfaces one context-aware partner suggestion based on the tab you're viewing — KWFinder when reviewing content, LinkMiner when auditing backlinks, SiteGround / Hostinger when reviewing performance, etc.
  
  Partners: SE Ranking, Mangools (KWFinder, SERPChecker, SERPWatcher, LinkMiner, SiteProfiler), SiteGround, Hostinger, Make.com, Parallels, Envato.
  
  Each link is clearly labeled "Affiliate" / "Quảng cáo" and includes affiliate tracking codes plus UTM tags. The partner sees that you arrived from this extension — never which page you were auditing. We earn a small commission if you sign up; the price you pay is the same. Toggle off anytime in Settings → "Tool recommendations".
  
  ▸ PERMISSIONS
  
  • activeTab — read the focused tab when you click the icon
  • scripting — inject the audit scanner
  • storage — persist settings, 50-entry rank history, click counters
  • downloads — export audits as JSON / CSV / HTML
  • alarms — periodic freshness check for rank results
  • Content scripts on Google search pages — required for live SERP rank tracking; runs only on the 20 listed Google domains, never any other site
