- Add middleware.ts at project root (proper Vercel Routing Middleware) - Runs server-side on every request before page loads - Only tracks requests from known AI crawlers (GPTBot, ClaudeBot, etc.) - Sends 'crawler_pageview' event to PostHog with crawler_name - No layout changes needed - middleware intercepts all requests - Uses matcher to skip static assets Amp-Thread-ID: https://ampcode.com/threads/T-019bc889-197d-71fb-b47e-990975761a3a Co-authored-by: Amp <amp@ampcode.com>

## Summary AI crawlers (GPTBot, ClaudeBot, PerplexityBot, etc.) don't execute JavaScript, so they're invisible to PostHog's client-side tracking. This PR adds a server-side tracking pixel that captures crawler visits. ## Changes - **`docs/api/track-crawler.ts`** - Vercel serverless function that: - Serves a 1x1 transparent GIF - Logs user-agent to PostHog server-side - Detects 30+ known AI crawler patterns - Tags events with `is_crawler: true` and `crawler_name` - **`docs/layout.tsx`** - Adds invisible tracking pixel to every page ## Tracked Crawlers GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, anthropic-ai, PerplexityBot, Google-Extended, Googlebot, Bingbot, Amazonbot, CCBot, Bytespider, YouBot, and more. ## PostHog Event - **Event name:** `server_pageview` - **Properties:** `is_crawler`, `crawler_name`, `user_agent`, `path` ## Query Example ```sql SELECT crawler_name, count() as visits FROM events WHERE event = 'server_pageview' AND properties.is_crawler = true GROUP BY crawler_name ORDER BY visits DESC ``` Co-authored-by: Amp <amp@ampcode.com>
