Page size is within limits

page_size

Checks that total page size is within limits.

What does this rule check?

Total page size includes HTML, CSS, JavaScript, images, and all other resources. Large pages take longer to download, especially on mobile networks. The recommended total size is under 3MB.

Why is this important?

Large pages result in slow load times, especially on mobile. This hurts user experience, increases bounce rate, and negatively affects Core Web Vitals scores.

How to fix

Compress images, minify CSS/JS, enable gzip/brotli compression, lazy-load below-fold resources, and remove unused code.

Examples

<!-- 8MB total page size with uncompressed images -->

<!-- 1.5MB total page size with optimized assets -->
