What is responsive design?
SEO Definition and Examples
Responsive design is a web design method that makes a site automatically adapt to any screen size (desktop, tablet, mobile).
Full Definition: What is responsive design
Responsive design uses CSS media queries to adapt the page layout based on screen width. Example: on desktop a page has 3 columns; on tablet 2 columns; on mobile 1 column. CSS determines this automatically. The HTML stays the same — only the CSS changes. The alternative (bad): a separate mobile site (m.site.com) — dual management, sync issues. Google recommends responsive design as best practice. Mobile-first responsive: design for mobile first, then scale up to desktop with media queries for larger screens.
Why Does Responsive Design Matter for SEO?
Responsive design = a single site version, easily maintained. Mobile-first = ranks well on mobile. Non-responsive sites = frustrate users on mobile = high bounce rate = poor ranking.
