Over 60% of website visits now happen on mobile devices, and Google primarily uses your site's mobile version for search rankings ("mobile-first indexing"). A responsive website automatically adjusts its layout, images, and menus to fit any screen size — no separate mobile site needed. Non-responsive sites often show tiny unreadable text, broken layouts, or require constant zooming/scrolling on phones, which frustrates visitors and increases bounce rate. Every website we build is fully responsive and tested across common device sizes before launch.
