Performance for AI Crawlers
AI crawlers have limited resources and time budgets. Fast, efficient pages are more likely to be fully indexed and cited.
Why Performance Matters
AI crawlers face constraints:
- Time limits — May abandon slow pages
- Resource budgets — Limited JavaScript execution
- Crawl quotas — Faster sites get crawled more
- Content prioritization — Quick access to main content
Key Metrics
| Metric | Target | Why It Matters |
|---|---|---|
| Time to First Byte | < 200ms | Server responsiveness |
| First Contentful Paint | < 1.5s | Content accessibility |
| Largest Contentful Paint | < 2.5s | Main content visibility |
| Total Blocking Time | < 200ms | JavaScript execution |
Optimization Strategies
1. Server-Side Rendering
Ensure content is in initial HTML:
// Next.js - SSR or SSG
export async function getStaticProps() {
return {
props: { content: await getContent() }
}
}
2. Minimize JavaScript
AI crawlers may not execute all JavaScript:
- Use SSR/SSG for content
- Avoid JS-only navigation
- Include meta tags in
<head>
3. Optimize Images
<img
src="image.webp"
alt="Descriptive alt text"
width="800"
height="600"
loading="lazy"
>
4. Enable Caching
# .htaccess or server config
Cache-Control: public, max-age=31536000
Testing Tools

Best Practices
- SSR/SSG — Don't rely on client-side rendering
- Fast TTFB — Optimize server response time
- Minimal JS — Critical content without JavaScript
- Efficient assets — Optimized images, minimal CSS
- CDN — Fast global access
