HTML Compression

Checks if GZIP or Brotli compression is enabled.

What is this check?

This check verifies if your web server is using compression (like Gzip or Brotli) to reduce the file size of your text-based assets (HTML, CSS, JavaScript) before sending them to the browser.

Why is it important?

Compression can reduce file sizes by up to 70-80%. This is one of the most effective ways to decrease page load times, as smaller files are downloaded much faster.

What is the impact?

Not using compression is a major missed opportunity for performance optimization. It leads to significantly slower load times, especially for users on slower connections.
