Total page weight
A page that's too large loads slowly.
What it is
Page weight is the sum of all downloaded resources: HTML, CSS, JS, images, fonts, videos. The larger it is, the longer it takes and the more data is transferred.
Why it matters
Heavy pages load slowly, especially on mobile and limited data. A large part of the weight tends to be in unoptimized images and bulky JavaScript.
How to do it
- 1Optimize images (format, compression, dimensions, lazy loading): usually the biggest saving.
- 2Minify and combine CSS/JS, remove unused code.
- 3Enable compression and caching.
- 4Limit heavy external scripts and embeds (widgets, maps, videos): load them only on demand.
Conclusion
Address page weight top-down: images and JavaScript first (the largest parts), then compression and caching. A lighter page = faster loading, better Core Web Vitals, and a lower bounce rate, especially on mobile.
