Page Speed
Page speed is how quickly a page becomes visible and usable, a driver of both conversion and search visibility.
What page speed is
Page speed is how fast a page becomes visible and usable: content appearing, taps responding, layout settling.
It’s measured both in lab tests and from real visitors’ devices, and the real-world numbers are the ones that count.
Why page speed matters
Slow pages bleed twice: visitors abandon before content appears, and search engines fold speed signals into rankings. Every second of delay is paid in both bounces and reach.
What usually slows stores down
- Oversized, unoptimized images
- Third-party scripts stacking up: pixels, chats, apps
- Render-blocking code before content paints
- Slow hosting and missing caching or CDN
Frequently asked questions
Where should speed work start?
Images and scripts, on the highest-traffic templates: compress and lazy-load the first, audit and cut the second. Most stores find seconds there before touching infrastructure.
Do third-party widgets have to hurt speed?
No: well-built ones load asynchronously after content paints. Test the page before and after adding any script, and cut the ones that don’t earn their milliseconds.
