Firecrawl Extension for Claude SEO

This skill requires the Firecrawl extension to be installed:

./extensions/firecrawl/install.sh

**Check availability:** Before using any Firecrawl tool, verify the MCP server is connected by checking if `firecrawl_scrape` or any Firecrawl tool is available. If tools are not available, inform the user the extension is not installed and provide install instructions.

Quick Reference

| Command | Purpose | |---------|---------| | `/seo firecrawl crawl <url>` | Full-site crawl with content extraction | | `/seo firecrawl map <url>` | Discover site structure (URLs only, fast) | | `/seo firecrawl scrape <url>` | Single-page scrape with JS rendering | | `/seo firecrawl search <query> <url>` | Search within a crawled site |

Commands

crawl -- Full-Site Crawl

Crawl an entire website starting from the given URL. Returns page content, metadata, and links for all discovered pages.

**MCP Tool:** `firecrawl_crawl`

**Parameters:**

• `url` (required): Starting URL to crawl
• `limit`: Max pages to crawl (default: 100, max: 500)
• `maxDepth`: Max link depth from start URL (default: 3)
• `includePaths`: Array of glob patterns to include (e.g., `["/blog/*"]`)
• `excludePaths`: Array of glob patterns to exclude (e.g., `["/admin/*", "/api/*"]`)
• `scrapeOptions.formats`: Output formats -- `["markdown", "html", "links"]`

**SEO Usage Patterns:** 1. **Comprehensive audit crawl**: Crawl full site, extract all pages for subagent analysis 2. **Section-focused crawl**: Use `includePaths` to audit only `/blog/*` or `/products/*` 3. **Broken link detection**: Crawl with `["links"]` format, check all hrefs for 404s 4. **Content inventory**: Extract all page titles, meta descriptions, H1s at scale 5. **SPA/JS-rendered sites**: Firecrawl renders JavaScript, solving the Issue #11 problem

**Example orchestration for `/seo audit`:**

1. firecrawl_map(url) -> get all URLs (fast, no content)
2. Filter to top 50 most important pages (homepage, key sections)
3. firecrawl_crawl(url, limit=50) -> get full content
4. Feed content to seo-technical, seo-content, seo-schema agents

**Cost awareness:**

• Free tier: 500 credits/month
• 1 credit = 1 page crawled or scraped
• Map operations are cheaper (0.5 credits per URL discovered)
• Always inform user of estimated credit usage before large crawls

map -- Site Structure Discovery

Discover all URLs on a website without fetching content. Fast and credit-efficient.

**MCP Tool:** `firecrawl_map`

**Parameters:**

• `url` (required): Website URL to map
• `limit`: Max URLs to discover (default: 5000)
• `search`: Optional search term to filter URLs

**SEO Usage Patterns:** 1. **Sitemap comparison**: Map site, compare discovered URLs vs XML sitemap 2. **Orphan page detection**: URLs in sitemap but not linked from any page 3. **Crawl budget analysis**: Total indexable pages vs pages linked from homepage 4. **URL pattern analysis**: Identify URL structure patterns, duplicates, parameter bloat 5. **Pre-audit discovery**: Run map first, then targeted crawl on key sections

**Output:** Array of URLs. Present as:

Site: example.com
Pages discovered: 342

URL Pattern Breakdown:
  /blog/*          - 128 pages (37%)
  /products/*      - 89 pages (26%)
  /category/*      - 45 pages (13%)
  /pages/*         - 32 pages (9%)
  / (root pages)   - 48 pages (14%)

scrape -- Single-Page Deep Scrape

Scrape a single page with full JavaScript rendering. More thorough than `fetch_page.py` because it executes JS and waits for dynamic content.

**MCP Tool:** `firecrawl_scrape`

**Parameters:**

• `url` (required): Page URL to scrape
• `formats`: Output formats -- `["markdown", "html", "links", "screenshot"]`
• `onlyMainContent`: Strip nav/footer/sidebar (default: true)
• `waitFor`: CSS selector or milliseconds to wait for content
• `timeout`: Request timeout in ms (default: 30000)
• `actions`: Browser actions before scraping (click, scroll, wait)

**SEO Usage Patterns:** 1. **SPA content extraction**: Scrape JS-rendered React/Vue/Angular pages 2. **Dynamic content audit**: Pages with lazy-loaded content below the fold 3. **Paywall/login detection**: Identify content behind authentication walls 4. **Main content extraction**: Use `onlyMainContent` for clean E-E-A-T analysis 5. **Screenshot capture**: Use `screenshot` format for visual analysis

**When to use scrape vs fetch_page.py:** | Scenario | Use | |----------|-----| | Static HTML page | `fetch_page.py` (no API cost) | | JS-rendered SPA | `firecrawl_scrape` (renders JS) | | Need response headers | `fetch_page.py` (returns headers) | | Need clean markdown | `firecrawl_scrape` (better extraction) | | Rate-limited/blocked | `firecrawl_scrape` (handles anti-bot) |

search -- Site-Scoped Search

Search within a website for specific content. Useful for finding pages related to a topic without crawling everything.

**MCP Tool:** `firecrawl_search`

**Parameters:**

• `query` (required): Search query
• `url` (required): Website to search within
• `limit`: Max results (default: 10)
• `scrapeOptions.formats`: Output format for matched pages

**SEO Usage Patterns:** 1. **Content gap validation**: Search for a keyword on the site to check if content exists 2. **Internal linking opportunities**: Find pages mentioning a topic that could link to each other 3. **Duplicate content detection**: Search for key phrases to find near-duplicates 4. **Competitor content research**: Search competitor site for specific topics
