# PageTold > PageTold is a website technology stack detector and AI-readiness (GEO) assessment platform: through a browser extension and no-install web detection, it detects a website's tech stack and scores sites 0-100 across six dimensions (Discoverability, Accessibility, Parsability, Understandability, Trust, Content Quality) with actionable recommendations to help sites get understood, cited, and recommended by generative AI. ## Product positioning PageTold (the AI-era website checkup / GEO readiness quantification platform) helps website owners understand and improve how their site performs in the generative-AI retrieval ecosystem. It turns AI comprehensibility into quantifiable, fixable engineering metrics - from AI-crawler discoverability to page semantic structure, content quality, and security trust - and outputs a 0-100 AI readiness score with an itemized improvement checklist. ## Scoring model (six dimensions) PageTold's AI readiness score is based on public, authoritative technical standards and weighs six dimensions into a 0-100 score: 1. **Discoverability**: Detects signals such as llms.txt, Schema.org structured data, Open Graph, hreflang, and sitemap to assess whether AI crawlers can find the site. 2. **Accessibility**: Checks HTTPS reachability, robots.txt allowances, status codes, and redirects to ensure AI crawlers can reach the site. 3. **Parsability**: Checks semantic HTML, JSON-LD, and sitemaps to assess whether page structure can be accurately understood. 4. **Understandability**: Evaluates body structure, heading hierarchy, and content density to ensure AI can accurately extract key points. 5. **Trust**: Checks security response headers, TLS configuration, and link quality as trust signals. 6. **Content Quality**: Evaluates content depth, freshness, and authority signals; higher-quality content is more likely to be cited by AI. ## Capabilities - **Free browser extension (Chrome/Edge MV3)**: Local detection on by default, zero network, zero privacy upload, three-tier consent management; open any public page and see the AI readiness badge instantly in the address bar. - **No-install web detection**: Paste a URL and get a score in seconds, no registration required. - **Web insights console**: Technology overview, competitor comparison, AI experience reports, and improvement checklists. - **Public technical profiles**: Publicly shareable pages for a site's AI readiness report. - **Open API**: Usage-based pricing with Python / Node / Go SDKs. ## Privacy and compliance - Local detection is on by default (zero network, zero PII, no consent required). - Cloud contribution is explicit opt-in (off by default, revocable anytime, 14-day cooling-off period). - Zero sensitive personal data collection: emails, phone numbers, cookie content, and browsing history are never stored. - Protected sites (banking / healthcare / government / email / intranet) and sensitive paths such as */api/, */admin/, and */login are automatically skipped from collection. ## Usage 1. Install the browser extension (Chrome / Edge); local detection takes effect immediately. 2. Or paste a URL directly on the site for a no-install score in seconds. 3. Sign in to the web console for technology overview, competitor comparison, and improvement checklists. ## Key pages - [Homepage](https://www.pagetold.com/): paste a URL and get an AI readiness score in seconds - [Domain search / public lookup](https://www.pagetold.com/search): public domain AI readiness lookup - [Methodology](https://www.pagetold.com/methodology): six-dimension weighted scoring standard and calculation logic - [Benchmark](https://www.pagetold.com/benchmark): industry benchmark comparison - [Learn hub](https://www.pagetold.com/learn/index.html): GEO, AI readiness and tech stack detection guides - [What is GEO](https://www.pagetold.com/learn/what-is-geo.html): guide to Generative Engine Optimization - [What is an AI readiness score](https://www.pagetold.com/learn/what-is-ai-readiness-score.html): guide to the 0-100 AI readiness score - [How to detect a website's technology stack](https://www.pagetold.com/learn/how-to-detect-website-technology-stack.html): tech stack detection guide - [Contact](https://www.pagetold.com/contact) - [Privacy policy](https://www.pagetold.com/privacy-policy.html) ## Technical standards and references - [Schema.org structured data](https://schema.org/) - [llms.txt spec (LLM-friendly content manifest)](https://llmstxt.org/) - [Sitemaps protocol](https://www.sitemaps.org/) - [Robots exclusion protocol](https://developers.google.com/search/docs/crawling-indexing/robots/intro) - [GPTBot crawling guide](https://openai.com/gptbot)
