What to test
- Can you read the headline without zooming?
- Can you find and tap the primary CTA with one hand?
- Do phone numbers call, addresses open maps, and forms work without a fight?
- Does the navigation stay understandable on a narrow screen?
- Are images and popups helping the task instead of covering it?
Why it matters
A page can look polished on a laptop and still lose ready buyers on a phone. Mobile friction often shows up in basic tasks: finding hours, understanding a service, calling, booking, or filling out a short form.
Common fixes
- Use readable text and tap targets with breathing room.
- Keep the first screen focused on the offer and next action.
- Reduce form fields and make input types match the question.
- Test the complete path on an actual phone, not only a resized browser window.
