Look at the first screen
Main copy, imagery and CTA should appear without depending on heavy effects. Set image dimensions to prevent shifts. Load essential content first and secondary features on demand.
Test the real flow
Open menus, use filters, complete forms and recover from errors on a small screen. Performance includes interaction response and visual stability, not just initial loading.
Measure with context
Compare measurements under similar conditions and follow real-user data when available. Conversion changes can have multiple causes; do not automatically attribute every difference to speed.
