Practical explanation:
A responsive website doesn't have a separate mobile version. Instead, the layout reflows based on the device being used. Text stays readable, buttons stay tappable, images resize — all without the user having to zoom or scroll sideways.
More than half of web traffic today comes from mobile devices. A site that works poorly on a phone loses visitors before they even read what you offer. Diligently builds responsive websites as standard across all its web development packages, including optimisation for mobile and tablet.
Why it matters for SEO
Google uses mobile-first indexing, meaning it primarily evaluates the mobile version of your site when deciding how to rank it. A site that performs poorly on mobile is likely to rank lower in search results, regardless of how good the content is. A better user experience leads to longer sessions, which is a positive signal for Google.
