Mobile visitors need readable information and reachable actions without overlays covering the page. Test the full journey on a phone.
Prioritise the decision sequence
Present the offer, fit, evidence and next step in a logical order. Avoid forcing a desktop multi-column layout into tiny mobile columns. Keep specifications readable and allow long technical terms to wrap without creating horizontal scrolling.
Allow room for interaction
Separate adjacent buttons and make labels describe their action. Check fixed contact controls against browser bars, cookie notices and the on-screen keyboard. A sticky button should not cover form errors, privacy text or the final submit control.
Review both languages and states
Test longer translated labels, validation messages and successful submission. Rotate the device and increase text size. Confirm telephone and messaging links use the intended number and that visitors can return to the page after opening another app.
