Mobile-First or Lose Half Your Traffic — It's Not Optional Anymore
Most of your visitors are on a phone. If your site isn't built for them first, you're frustrating the majority to please the minority.

Google indexes mobile first
Google primarily ranks based on your mobile site. A great desktop experience with a clunky mobile one is a ranking liability, not just a UX one.
