Quick Reference
Element Code: PE-010
Issue: Text-based resources not served with compression
Impact: Larger transfer sizes, slower loading
Fix: Enable gzip or Brotli compression on server
Detection: Lighthouse, PageSpeed Insights, HTTP header inspection
What Is This Issue?
Text resources (HTML, CSS, JavaScript, JSON) can be compressed by 60-80% using gzip or Brotli. Without compression, users download much more data than necessary.
Why This Matters for Your Website
Compression is one of the easiest and most effective performance improvements. It reduces bandwidth costs and speeds up loading for all users.
How to Fix This Issue
- Enable on server: Configure Apache, Nginx, or CDN
- Prefer Brotli: Better compression than gzip
- Verify headers: Check Content-Encoding in response
Tools for Detection
- Lighthouse: Reports uncompressed resources
- DevTools Network: Shows Content-Encoding header
TL;DR (The Simple Version)
Your text files are not compressed. Enable gzip or Brotli compression on your server to reduce transfer sizes by 60-80%.
