Text resources not compressed: what it is, why it matters, and how to fix it
HTML, CSS, or JavaScript files are being served without gzip or brotli compression. Text compression typically reduces transfer size by 60-80%.
Where this fits: performance in SEO
Why text resources not compressed hurts your rankings
Uncompressed text resources unnecessarily increase page load time and bandwidth consumption. Compression is one of the easiest and most impactful performance optimizations available. Google PageSpeed Insights flags missing compression as a high-priority issue, and it directly affects Core Web Vitals scores.
This is a medium-severity issue: individually modest, but it compounds — dozens of medium issues across hundreds of pages add up to a real quality deficit in how search engines assess the site.
How to fix it
Enable gzip or brotli compression on your web server for text-based content types (text/html, text/css, application/javascript, application/json, image/svg+xml). Most web servers and CDNs support compression with a simple configuration change. Brotli offers 15-25% better compression than gzip.
# Nginx configuration
