Mobile Page Speed Optimisation
Reducing page weight and processing cost specifically for cellular connections and the limited computing power of a phone.
Analogy Mental model
Driving a small-engine car up a mountain road. Everything unnecessary comes out of the boot before the climb, or the car simply does not make it.
In practice What you actually do
Mobile scoring simulates a mid-range Android device on a slow connection, which is why the number runs well below the desktop score. Serve smaller images through responsive picture elements, drop heavy animation and chat widgets on small screens, and stop shipping desktop-sized hero banners to phones.
