What is GZIP Compression?

GZIP is a file compression method that shrinks HTML, CSS, JavaScript, and other text-based files before sending them to visitors’ browsers.

How It Works:

Server compresses files (e.g., a 100KB CSS file → 30KB).
Browser receives & decompresses files instantly.
Result: Faster load times, lower bandwidth usage.

File Types GZIP Affects:

✅ HTML
✅ CSS
✅ JavaScript
✅ JSON & XML
❌ Images (JPEG/PNG already compressed)

Why GZIP Compression Matters for SEO & Speed

1. Faster Page Load Times = Better Rankings

Google’s Core Web Vitals prioritize speed—GZIP helps pass these metrics.

2. Reduced Bandwidth Costs

Smaller files = lower hosting data transfer costs.

3. Improved User Experience

Visitors stay longer on fast-loading sites.

4. Higher Conversion Rates

Amazon found that 100ms slower load times = 1% lost sales.
