The middle website of the 178 we scoredi
2.25 MBan average page view
Why weight matters
- Slower.Every megabyte downloaded is time spent waiting, on a phone, a laptop or a slow connection. Lighter pages appear sooner.
- Costs more.Many people pay for every megabyte they use, especially on mobile phones. A heavy website spends their data, not yours.
- Carbon.Moving and storing data uses electricity. Across millions of page views, the waste really starts to add up.
- No harder to do well.A light website looks and works the same as a heavy one. Building it properly costs about the same.
