Why it matters
HTTP compression like gzip or Brotli can significantly reduce HTML file sizes, leading to faster page loads and lower bandwidth usage. Without compression, users experience slower sites, which can negatively affect SEO rankings and user satisfaction.
Impact
Uncompressed pages load slower and may rank lower in search results due to poor performance.
How it's detected
An automated crawler checks the response headers for 'Content-Encoding: gzip' or 'br' on large HTML files and flags pages missing these.
Common causes
- Web server misconfiguration or default settings not enabling compression
- CDN or proxy not configured to compress HTML responses
- Older server software lacking compression support
- Compression disabled due to perceived CPU overhead
How to fix it
Code examples
Enable gzip in nginx
gzip on;
gzip_types text/html;Enable gzip (DEFLATE) in Apache
AddOutputFilterByType DEFLATE text/htmlFAQ
How can I check if my pages are compressed?
Use browser developer tools or online tools like webpagetest.org to inspect the 'Content-Encoding' header in the response.
Will enabling compression affect my server's CPU usage?
Compression uses some CPU, but the performance and bandwidth benefits usually outweigh the small increase in CPU load.
Does my CDN handle compression automatically?
Most major CDNs enable compression by default, but you should verify and enable it in your CDN's settings if needed.
Is it safe to enable both gzip and Brotli?
Yes. Brotli is preferred by modern browsers, but servers can fall back to gzip for older clients.
