Consider the largest visual
The large visual on the initial screen sets the tone for the page, but improper sizing can lead to unnecessary data downloads. Using a massive file intended for desktop on a mobile device does not provide a good experience. Space for the visual should be reserved in advance so it doesn't push text down upon loading. Purely decorative elements that convey no meaning should not overshadow critical content.
What purpose does the animation serve?
A transition can help users perceive a choice, understand a process, or notice an important outcome. Conversely, constantly flickering elements are distracting. Motion should be adaptable, simplifying based on device capabilities and user preferences. Providing feedback when a button is pressed can be a more significant improvement than a complex 3D scene.
Interpret measurements correctly
A single desktop test score does not represent the experience of every customer. Factors such as mobile connectivity, low-power devices, and whether it is a first or repeat visit can yield different results. Record the environment in which the measurement was taken. Base improvements not just on the score, but on... Evaluate based on readability, form completion, and ease of navigation between pages.
