# Minimize critical request chains

Long chains of dependent requests delay the initial rendering of the page, as each resource must wait for its parent to be fetched and processed.

## Quick Reference

- Reduce the depth of dependent resource requests
- Inline critical CSS to avoid extra network roundtrips
- Use `preload` hints for essential assets found deep in the chain

## Check

Identify long chains of dependent requests that block the critical rendering path using Lighthouse or WebPageTest.
