Slow Server Response (TTFB)

High time-to-first-byte hurts user experience and can cap crawl efficiency.

Why this matters

  • - Users bounce when pages feel slow.
  • - Crawlers may fetch fewer URLs per session.
  • - Core Web Vitals and UX signals can suffer.

How to fix it

  1. 1. Enable edge caching and HTML page cache.
  2. 2. Optimize database queries and application cold starts.
  3. 3. Use a CDN in front of your origin.

Weak example

TTFB consistently above 1.2s on key templates.

Better example

TTFB under 300ms for cached pages; under 600ms for dynamic.
