+# Crawl Budget Optimizer
+
+Analyze server access logs to identify crawl budget waste and generate optimization recommendations for search engine bots.
+
+## Capabilities
+
+1. **Log Analysis**: Parse Nginx/Apache/CloudFront access logs to extract bot crawl data
+2. **Bot Profiling**: Per-bot behavior analysis (Googlebot, Yeti, Bingbot, Daumoa)
+3. **Waste Detection**: Parameter URLs, redirect chains, soft 404s, duplicate URL variants
+4. **Orphan Pages**: Pages in sitemap but uncrawled, and crawled pages not in sitemap
+5. **Recommendations**: Prioritized action items for crawl budget optimization
+
+## Workflow
+
+1. Parse server access log with `log_parser.py`
+2. Run crawl budget analysis with `crawl_budget_analyzer.py`
+3. Compare with sitemap URLs for orphan page detection
+4. Optionally compare with Ahrefs page history data
+5. Generate Korean-language report with recommendations
+6. Save to Notion SEO Audit Log database
+
+## Tools Used
+
+- **Ahrefs**: `site-explorer-pages-history` for indexed page comparison
+- **Notion**: Save audit report to database `2c8581e5-8a1e-8035-880b-e38cefc2f3ef`
