## Why This Exists

Every SEO tool costs $100-300/month. Ahrefs, SEMrush, Moz — they're great, but they're designed for humans clicking dashboards.

**SEOctopus is different.** It's designed for AI. Your Claude assistant can pull rankings, analytics, and audit data in real-time through MCP — no browser tabs, no copy-pasting, no monthly subscription.

You ask a question. Your AI answers with live data.

```
You: "Where do we rank for 'best mcp servers' and how's our traffic this month?"

Claude: Let me check... [calls rank_check + analytics_overview]

Rankings:
  - "best mcp servers" → #7 (up from #12 last week)
  - "mcp server tools" → #3

Traffic (last 28 days):
  - Sessions: 4,231 (+18% vs previous period)
  - Top source: Organic Search (62%)
  - Bounce rate: 34% (good)
```

## If You Only Try 3 Things, Try These

| Tool | What It Does | Why It's Great |
|------|-------------|----------------|
| `rank_check` | Live Google rankings for any keyword | No API key needed — uses stealth Playwright scraping with anti-detection |
| `analytics_overview` | Full GA4 dashboard in one call | Sessions, users, bounce rate, top pages, traffic sources — with period comparison |
| `octo_score` | 0-100 SEO score weighted by actual Google ranking factors | Research-backed weights, letter grades, actionable recommendations |

---

## The 8 Arms (23 Tools)

### Arm 1: Rank Tracking
*No API keys required. Uses stealth browser automation with anti-detection.*

| Tool | What You Get |
|------|-------------|
| `rank_check` | Where your domain ranks for specific keywords (scans top 100) |
| `rank_history` | Trend analysis: up, down, or stable over time (stored locally in SQLite) |
| `rank_competitors` | Who's ranking above you and why |
| `rank_serp_features` | Featured snippets, People Also Ask, knowledge panels, image packs |

### Arm 2: Google Analytics (GA4)
*Requires OAuth2 setup (one-time, 5 minutes).*

| Tool | What You Get |
|------|-------------|
| `analytics_overview` | Sessions, users, bounce rate, top pages, traffic sources — with comparison periods |
| `analytics_pages` | Per-page performance sorted by pageviews, engagement, or conversions |
| `analytics_traffic` | Traffic breakdown by source, medium, campaign, or channel |
| `analytics_realtime` | Right-now data: active users, current pages, live events |

### Arm 3: SEO Auditing
*Just pass a URL. No setup needed.*

| Tool | What You Get |
|------|-------------|

| `audit_content` | Word count, Flesch readability, keyword density, heading hierarchy |

|------|-------------|
| `keywords_search_console` | Your actual keyword performance: clicks, impressions, CTR, avg position |
| `keywords_suggestions` | Google Autocomplete + People Also Ask expansion from a seed keyword |
| `keywords_gaps` | Quick wins: keywords where you have high impressions but poor position (positions 4-20) |
| `keywords_cluster` | Group keywords by topic and infer search intent (informational/transactional/navigational) |

### Arm 5: Competitive Analysis
*Uses Playwright for SERP scraping + Cheerio for page analysis.*

| Tool | What You Get |
|------|-------------|
| `competitive_analyze` | Side-by-side comparison: word count, headings, images, structured data, load time |
| `competitive_content_gap` | Topics and headings your competitors cover that you don't |

## OctoScore — The SEO Rating System

Not another vanity metric. OctoScore is weighted by what Google actually cares about:

| Factor | Weight | What It Measures | Why It Matters |
|--------|--------|-----------------|----------------|
| Content Quality | **25%** | Word count, readability, depth | Google's #1 ranking signal |
| Core Web Vitals | **15%** | LCP, INP, CLS | Direct ranking factor since 2021 |
| Title Optimization | **12%** | Length, keyword placement | Highest CTR impact element |
| Mobile Friendly | **10%** | Viewport, responsive design | 60%+ of searches are mobile |
| User Engagement | **10%** | Bounce rate, time on page | Behavioral signals Google tracks |
| Backlinks | **8%** | External links pointing in | Still a top-3 ranking factor |
| Link Diversity | **7%** | Internal/external link mix | Healthy sites have balanced links |
| E-E-A-T | **5%** | Author, citations, trust | Critical for YMYL content |
| Freshness | **5%** | Last modified, publish date | Google rewards recently updated content |
| Topical Authority | **3%** | Heading coverage, semantic depth | Comprehensive content ranks better |

**Grades:** **A** (90+) · **B** (75-89) · **C** (60-74) · **D** (40-59) · **F** (<40)

Each score comes with prioritized recommendations ranked by estimated impact.

### Under the Hood

- **Anti-detection SERP scraping** — Random user agents, viewport sizes, human-like delays, webdriver spoofing via Playwright
- **SQLite with WAL** — Concurrent read/write for rank history tracking and trend detection
- **OAuth2 token management** — Auto-refresh, credential persistence, scoped to read-only
- **Rate limiting** — Built-in limiter respects Google API quotas
- **Lazy module loading** — Each tool dynamically imports its module for fast startup
- **3 report formats** — JSON for machines, Markdown for docs, HTML with dark theme for presentations

### Tech Stack

| What | Why |
|------|-----|
| TypeScript (ES2022, strict) | Type safety for 23 tool schemas |
| MCP SDK | Standard protocol for AI tool integration |
| Playwright | Stealth browser for rank tracking |
| googleapis | Official GA4 + Search Console client |
| Lighthouse | Performance auditing (same engine as Chrome DevTools) |
| Cheerio | Fast HTML parsing for audits |
| better-sqlite3 | Embedded storage, zero config |
| tsup | Fast builds, dual entry points |
