Heavy page footprint
Every byte transferred consumes energy. Heavier pages mean higher emissions per visit, and usually slower loads.
What it is
This check flags pages whose weight pushes their estimated carbon footprint above a healthy level.
Why it matters for SEO
A lighter page is faster and greener; performance and sustainability improvements reinforce each other and support better Core Web Vitals.
Example
Estimated CO2 - 1.9 g per visit (heavier than ~80% of pages)
How to fix
- Reduce image, script, and font weight.
- Lazy-load below-the-fold media.
- Cache aggressively and use an efficient CDN.
- Re-crawl to confirm the footprint dropped.
