- Privacy protection: Block sensitive directories like `/admin`, `/private`, or `/user-accounts` from AI crawlers
- Bandwidth management: Control the intensity of AI agent crawling during peak hours
Example robots.txt configuration for AI agent discovery:
```
User-agent: GPTBot
Allow: /
Crawl-delay: 1
User-agent: CCBot
Allow: /
Crawl-delay: 2
User-agent: PerplexityBot
Allow: /
Crawl-delay: 1
User-agent: *
Disallow: /admin/
Disallow: /private/
Crawl-delay: 5
```
This configuration specifically welcomes major AI agents while maintaining appropriate rate limits. The AI-optimized robots.txt generation approach ensures you're making strategic decisions about which AI systems can access your content.
