Heavy page
Total transferred bytes determine how fast a page loads, especially on mobile networks.
What it is
This check flags pages whose combined transferred size (HTML, CSS, JS, images, fonts) is excessive.
Why it matters for SEO
Heavy pages load slowly, worsen Core Web Vitals, cost users data, and increase carbon emissions per visit.
Example
Total page weight - 6.1 MB
How to fix
- Compress and resize images; adopt WebP/AVIF.
- Trim and split CSS/JS; remove unused code and heavy libraries.
- Enable text compression and caching; subset fonts.
- Re-crawl to confirm the page is lighter.
