# Technical SEO Audit

## Categories

### 1. Crawlability
- robots.txt: exists, valid, not blocking important resources
- XML sitemap: run `claude-seo run sitemap_discovery.py <url> --json`; require a
  valid entry in `found`, and report stale or unsafe robots.txt declarations
  separately from working fallback locations
- Noindex tags: intentional vs accidental
- Crawl depth: important pages within 3 clicks of homepage
- JavaScript rendering: check if critical content requires JS execution
- Crawl budget: for large sites (>10k pages), efficiency matters
- Googlebot **fetch limits**: Googlebot fetches the first **2MB of HTML** and first **64MB of a PDF** (uncompressed; 15MB is the broader crawler-infra default). Long-standing, not a 2026 change, but inline base64 images, oversized inline CSS/JS, or bloated nav can push critical content/JSON-LD past the cap and out of the index. Keep key content + structured data within the first 2MB.
