Responsive design at a glance
Responsive design is a way of building websites so they adapt automatically to any screen size, from a large desktop monitor to a phone. Instead of a separate mobile site, one flexible layout rearranges itself to fit the device, keeping the site readable and usable everywhere.
Why responsive design is essential
Most web traffic now comes from mobile devices, so a site that only looks good on desktop loses a large share of visitors. Google also indexes the mobile version of a site first, which means responsive design directly affects rankings as well as user experience. Today it is a baseline requirement, not an option.
FAQ
Is responsive design the same as mobile-friendly?
They are closely related. Responsive design is the technique of one flexible layout that adapts to every screen, which is the most common way to make a site mobile-friendly.
Does responsive design affect SEO?
Yes. Google uses mobile-first indexing and rewards mobile-friendly pages, so a responsive site tends to rank better and keep visitors longer.
