+# SEO Tool + IntelSight — Shared Architecture
+
+**Status:** OPEN
+**Date:** 2026-08-10
+**Products:** SEO Audit Tool (`git.itpropartner.com/ippadmin/seo-tool`), IntelSight (`intelsight.io`)
+
+---
+
+## 1. Core Principle
+
+Two products. One infrastructure layer. Zero product merge.
+
+| | SEO Audit Tool | IntelSight |
+|---|---|---|
+| **Buyer** | ITPP hosting client (small business owner) | Marketing VP, Founder, Strategy lead |
+| **Question** | "Why isn't my site getting traffic?" | "What are my competitors doing?" |
+| **Pricing** | Free / $49/mo Pro | $199–$1,499/mo |
+| **Current state** | Proposal (repo created Aug 10) | Proposal (July 25, 2026) |
+
+They share the crawl engine, the audit checker library, the report renderer, and the Super Search backend. They sell to different people, at different price points, through different channels.
+
+---
+
+## 2. Shared Infrastructure Layer
+
+```

+```
+
+### Crawler Engine
+
+- HTTP crawler that fetches and parses any URL
+- Extracts: HTML structure, meta tags, headings, links, images, structured data, performance metrics
+- Used by both products — SEO tool crawls the client's own site; IntelSight crawls competitor sites
+- Configurable depth, rate limiting, politeness
+
+### Audit Checker Library
+
+- 50+ reusable check functions: `check_meta_description()`, `check_og_tags()`, `check_canonical()`, `check_structured_data()`, `check_heading_hierarchy()`, `check_image_alts()`, `check_internal_links()`, `check_llms_txt()`
+- Each check returns: `{ status: pass|fail|warn, score: 0-100, fix: "", impact: high|medium|low, effort: low|medium|high }`
+- Used by both products — SEO tool runs all checks on the client's site; IntelSight runs summary checks on competitor sites
+
+### Report Renderer
+
+- Takes audit results and produces: HTML dashboard, PDF report, email summary
+- SEO tool renders: per-page issues, fix-it snippets, trend charts
+- IntelSight renders: competitive SEO comparison, AI visibility matrix, CI + SEO combined report
+
+### Super Search Backend
+
+- Already production-hardened: 7 providers, circuit breakers, caching, port 8899
+- Powers IntelSight's competitive intelligence queries
+- Powers SEO tool's AI engine visibility checks (GEO/AEO)

+
+## 3. Product-Specific Architecture
+
+### SEO Audit Tool
+
+```
+┌─────────────────────────────────────┐
+│ SEO AUDIT TOOL │
+│ │
+│ Launch Audit Monthly Crawl │
+│ (on deploy) (cron, 30 days) │
+│ │ │ │
+│ └──────┬───────┘ │
+│ │ │
+│ ┌────────┴────────┐ │
+│ │ Per-Site Audit │ │
+│ │ Dashboard │ │
+│ │ seo.itpropartner│ │

+│ └────────┬────────┘ │
+│ │ │
+│ ┌───────────┴───────────┐ │
+│ │ Fix-It Snippets │ │

+│ (Claude/Cursor/ (GEO/AEO check │
+│ Codex ready-made via Super Search)│
+│ fix instructions) │
+└─────────────────────────────────────┘
+```
+
+**Feature Enhancements (from SeoLoupe analysis):**
+
+| Enhancement | Effort | Value | Description |
+|---|---|---|---|
+| **AI Fix Prompt Generation** | Low | High | Each finding generates a ready-made prompt for Claude/Cursor/Codex — "Fix the meta description on /pricing. Current: '...' Suggested: '...'" |
+| **llms.txt Checking** | Low | Medium | Check if llms.txt exists and is well-formed. Flag missing or malformed. Zero-cost add to crawl phase |
+| **GEO/AEO Visibility Scan** | Medium | High | Query Super Search providers: "Is {domain} cited in AI search results?" Surface how the site appears in ChatGPT, Gemini, Claude, Perplexity |
+| **Impact x Effort Matrix** | Low | Medium | Formalize priority ranking as a 2x2 matrix (not just P0/P1/P2 list). Makes reports more actionable |
+| **<10s Scan Speed Target** | Medium | High | Automate end-to-end pipeline for instant feedback. Dopamine hit = conversion |
+| **MCP Server (Pro tier)** | Medium | High | Expose audit as MCP tools so external AI agents can trigger scans. First-mover in the agent ecosystem |
+
+### IntelSight
+
+```
+┌─────────────────────────────────────┐
+│ INTELSIGHT │
+│ │
+│ Competitor Market Analysis │
+│ Profiles (funding, moves, │
+│ (Crunchbase, team changes, │
+│ Hunter.io, product launches) │
+│ OSINT) │

+│ └───────────────────────┘ │
+│ │
+│ Competitor AI Alert Engine │
+│ Visibility (funding, team, │
+│ (GEO matrix) product changes) │
+└─────────────────────────────────────┘
+```
+
+**Feature Enhancements:**
+
+| Enhancement | Effort | Value | Description |
+|---|---|---|---|
+| **Competitive SEO Health Scan** | Medium | High | Crawl top 5 competitors and surface their SEO health side-by-side with yours. "Their meta tags are complete. Yours are missing on 12 pages." Uses the shared audit checker library |
+| **Competitor AI Visibility Matrix** | Medium | High | How visible are your competitors in ChatGPT, Gemini, Claude, Perplexity, Grok? Which competitors get cited? What queries? The GEO/AEO scan but applied to competitors |
+| **Combined CI + SEO Report** | Medium | Very High | One report per competitor: funding moves, team changes, product launches, AND their SEO health. "They raised $5M, hired a CMO, and their SEO score dropped 15 points — they're distracted, your window is now" |
+| **llms.txt Competitive Analysis** | Low | Low | Flag competitors who have/don't have llms.txt. Trend indicator — who's thinking about AI crawlers? |
+
+---
+
+## 4. Cross-Product Data Flow
+
+```
+SEO Audit Tool IntelSight
+────────────── ──────────
+Client site crawl ──────────────→ Competitive SEO baseline
+(anonymous, aggregated)
+
+ Shared Crawler
+ ←────────────── Competitor site crawl
+
+Client SEO scores ──────────────→ Industry benchmarks
+(aggregated, anon) "Average SMB scores 62/100.
+ Your clients average 78/100."
+
+ ←─────────────── IntelSight alerts
+ "Competitor X launched new site.
+ Run audit comparison?"
+```
+
+Key rule: **client data stays in the SEO tool. Competitor data stays in IntelSight.** The shared layer only moves aggregated, anonymous benchmarks between them. No client PII crosses the boundary.
+
+---
+
+## 5. Implementation Sequence
+
+### Phase 1: Foundation (Weeks 1-2)
+- Build the shared Crawler Engine (Python/requests, configurable depth, politeness)
+- Build the Audit Checker Library (50+ check functions)
+- Stand up shared API Gateway (FastAPI)
+- Separate databases per product
+
+### Phase 2: SEO Tool Launch (Weeks 3-4)
+- Launch Audit: auto-runs on CloudPanel deploy webhook
+- Fix-It Snippets: HTML output per finding
+- Monthly crawl cron
+- AI Fix Prompt Generation (low effort, high impact)
+- llms.txt checking
+- Impact x Effort matrix in reports
+- Dashboard at `seo.itpropartner.com`
+
+### Phase 3: IntelSight Enhancements (Weeks 5-8)
+- Competitive SEO Health Scan (uses shared audit checker)
+- Competitor AI Visibility Matrix (uses Super Search GEO queries)
+- Combined CI + SEO report template
+- MCP Server for external AI agent access
+
+### Phase 4: Cross-Product (Weeks 9-12)
+- Anonymous industry benchmarks from SEO tool data
+- IntelSight alerts triggering SEO comparisons
+- White-label dashboard for agency clients
+- <10s scan speed optimization
+
+---
+
+## 6. What Stays Separate
+
+| Layer | Separate? | Why |
+|---|---|---|
+| **Databases** | Separate | Client site data vs competitor intelligence — different access patterns, retention policies, privacy considerations |
+| **Auth / Tenants** | Separate | SEO tool: ITPP hosting auth (Stack Auth, existing). IntelSight: standalone SaaS auth with Stripe billing |
+| **Pricing / Billing** | Separate | SEO: bundled with hosting or $49/mo add-on. IntelSight: $199-1,499/mo standalone |
+| **Branding** | Separate | SEO: ITPP-branded, "your hosting includes this." IntelSight: standalone brand, intelsight.io |
+| **Go-to-Market** | Separate | SEO: hosting upsell, retention play. IntelSight: SaaS marketing, Product Hunt, direct sales |
+
+---
+
+## 7. Key Decisions
+
+| Decision | Status | Notes |
+|---|---|---|
+| Merge products into one platform? | **SETTLED: No** | Different buyers, different pricing, different GTM |
+| Share crawl engine? | **SETTLED: Yes** | Same underlying tech, no reason to build twice |
+| Share audit checker library? | **SETTLED: Yes** | Check functions are pure logic — zero product coupling |
+| Cross-product data sharing? | **OPEN** | Aggregated/anonymous only. Privacy boundary TBD |
+| SEO Tool MCP Server? | **OPEN** | Pro tier feature. Proximity to agent ecosystem is a differentiator |
+| IntelSight SEO report depth? | **OPEN** | Full audit (like SEO tool) or summary (top 20 checks)? Depends on crawl politeness and competitor detection risk |
+
