Why Your Site Fails on Phones

Interviewer: Mobile optimization seems obvious now. Why do beginners still get it wrong?

Jennifer: They test on their laptop, it looks fine, they move on. But 63% of Google searches happen on mobile devices. I check a site on my phone and the text is microscopic or buttons overlap.

Interviewer: What specific issues come up most?

Jennifer: Font sizes below 16 pixels that require zooming. Buttons placed too close together, so you tap the wrong one. Images that push content off-screen. Pop-ups that can't be closed on small screens. These aren't just annoying, they're ranking factors since Google's mobile-first indexing started in 2019.

Interviewer: How can someone catch these problems?

Jennifer: Actually test on real phones, not just resize your browser. Use Google's Mobile-Friendly Test tool. Check your Search Console for mobile usability errors. Last month, a client fixed three mobile issues and their mobile traffic jumped 34% in two weeks, same content, same rankings.

Interviewer: So it directly affects visibility?

Jennifer: Completely. Google ranks the mobile version of your site now, not desktop.
