Introduction
Most teams treat page speed as a technical detail. Visitors treat it as a first impression. Every extra second before a page responds is a moment where someone can decide to go elsewhere, and they rarely tell you they did.
This note walks through how to turn that quiet loss into a number you can plan around, using data you most likely already collect.
What slow actually costs
Start with the pages that matter most: the ones people reach before they enquire, book or buy. Compare how often visitors continue from fast loads and from slow loads. The gap between the two is the revenue you are leaving on the table.
If you cannot say what a slower page costs you, you cannot say what a faster one is worth.
Where to look first
- Large images that are served at full size
- Scripts that block the first paint
- Fonts that load late and shift the layout
Conclusion
Speed work pays for itself when it is measured against outcomes instead of scores. Pick a handful of key pages, track conversions next to load time, and review the numbers every week.
