+
+## Architecture
+
+The system is built with a modular architecture:
+
+```
+app.py                 # Main Streamlit application
+modules/
+  ├── technical_seo.py # PageSpeed Insights integration
+  └── content_audit.py # Web crawling and content analysis
+report_generator.py    # HTML report generation with charts
+pdf_generator.py       # PDF export functionality
+```
+
+## Report Structure
+
+1. **Executive Summary** - Overall health score and quick wins
+2. **Technical SEO** - Performance metrics and optimization opportunities  
+3. **Content Audit** - Metadata completeness and content quality
+4. **Competitor Analysis** - Basic performance comparison
+5. **Future Modules** - Placeholder sections for keywords, backlinks, etc.
+6. **Recommendations** - Prioritized action items
+
+## Success Metrics
+
+✅ Report generates without failures for multiple domains  
+✅ PageSpeed data fetched reliably via Google API  
+✅ Crawl completes within 200 pages, respecting robots.txt  
+✅ Charts render correctly in HTML and export cleanly to PDF  
+✅ Report structure matches defined format  
+✅ Professional visual design resembling agency decks
+
+## Contributing
+
+The system is designed to be extensible. To add new modules:
+
+1. Create a new module in `modules/` following the existing pattern
+2. Update `report_generator.py` to include the new section
+3. Add placeholder sections for future enhancements
+4. Update the main app to integrate the new module

+
+# PRD: One-Click SEO Report Generator (v1 MVP)
+
+## Objective
+
+Deliver a working demo system that generates a structured SEO report from a website URL.
+The report should highlight **content audit** and **technical SEO performance**, and demonstrate the framework for future modules (keywords, backlinks, competitors).
+
+---
+
+## Scope (v1)
+
+**In scope**
+
+1. **Input**:
+
+   * User enters website URL (and optional competitor domains).
+   * System validates and normalizes URL.
+
+2. **Modules implemented**:
+
+   * **Technical SEO** (PageSpeed Insights API)
+
+     * Mobile & desktop performance scores
+     * Core Web Vitals (LCP, CLS, INP)
+     * Key flagged issues (e.g., oversized images, render-blocking JS)
+   * **Content Audit** (custom crawl)
+
+     * # of pages discovered (via sitemap / bounded crawl, capped \~200)
+     * Metadata completeness (Title, Description, H1)
+     * Avg. word count per page
+     * CTA keyword presence (“contact”, “download”, etc.)
+     * Content freshness (last modified vs today)
+
+3. **Report generation**:
+
+   * Render as **HTML** report (modular sections).
+   * Provide **Download as PDF** option (same HTML rendered to PDF).
+   * Include **charts/visuals** (e.g., doughnut/pie for metadata completeness, freshness buckets, bar for Core Web Vitals vs benchmarks).
+
+4. **Interface**:
+
+   * **Streamlit app** for demo UI.
+   * Inputs: URL (+ optional competitor domains).
+   * Buttons: “Generate Report”, “Download PDF”.
+   * Report preview inline in Streamlit.
+
+**Out of scope (v1, stub/fallback only)**
+
+* Keyword Rankings (GSC/SEMrush) → show placeholder section.
+* Backlink Profile (Ahrefs/SEMrush) → placeholder section.
+* Competitor benchmarking → limited to PageSpeed/content freshness comparison if URLs provided.
+* GA4 / conversion metrics.
+
+---
+
+## Output structure (MVP report)
+
+1. **Executive Summary**
+
+   * Quick health snapshot: Technical performance + Content audit highlights.
+   * “Quick wins” (e.g., missing metadata, low mobile score).
+
+2. **Technical SEO**
+
+   * PageSpeed scores (Mobile + Desktop).
+   * Core Web Vitals chart.
+   * Top issues flagged.
+
+3. **Content Audit**
+
+   * Indexed pages count (discovered pages).
+   * Metadata completeness (% with title, description, H1).
+   * Avg. word count per page (vs benchmark 800–1200 words).
+   * CTA presence (% pages with calls-to-action).
+   * Content freshness buckets (<6 months, 6–18 months, >18 months).
+
+4. **Competitor Light (optional if input provided)**
+
+   * PageSpeed score comparison.
+   * Content freshness comparison (avg. last-modified).
+
+5. **Placeholder sections**
+
+   * Keywords, backlinks, conversions → visible but labeled as “to be added in future versions.”
+
+6. **Recommendations**
+
+   * Auto-generated based on findings (ruleset from benchmarks).
+   * Example: “50% of pages missing meta descriptions → prioritize metadata optimization.”
+
+---
+
+## Success criteria
+
+* **Functional**: User can input a URL and receive a full HTML + PDF report in <3 minutes.
+* **Professional output**: Report visually resembles an agency deck (charts, tables, summaries).
+* **Modular design**: Technical SEO and Content Audit implemented as independent modules, with stubs for others.
+* **Extensible**: Report generator uses templates so adding future modules is straightforward.
+
+---
+
+## Evaluation metrics
+
+* Report generates without failures for at least 3 different domains.
+* PageSpeed data fetched reliably via Google API.
+* Crawl completes within 200 pages, respecting robots.txt.
+* Charts render correctly in HTML and export cleanly to PDF.
+* Report structure matches defined format.
+
+---
+
+This PRD keeps the v1 realistic (2–4 days build) while laying the bones for the full system.
+
+Do you want me to next **map this PRD to required API keys/libraries** so we know what accounts to set up before coding, or should we first design the **module interfaces (input/output contract)**?
