Mobile-Friendly (Responsive Design)
A mobile-friendly site automatically adjusts to look and work well on phones and tablets, not just computers. Since most web traffic is now on phones, it's no longer optional.

In plain English
A mobile-friendly (or "responsive") website reshapes itself to fit whatever screen it's on. On a computer it might show three columns; on a phone those stack into one easy-to-scroll column, with text and buttons sized for a thumb. The same site, automatically rearranged so it's comfortable to use whether someone's on a laptop or a phone in a parking lot.
Why it matters for your business
Most people will visit your site on a phone — often more than half. If it's hard to read, pinch-to-zoom awkward, or the buttons are too small to tap, those visitors leave, and you never know why. On top of that, Google judges your site mainly by its mobile version, so a poor mobile experience can quietly drag down your search ranking as well.
What to check
Pull your site up on your own phone and actually try to do what a customer would — read, tap, scroll, submit a form. If it's a struggle for you, it's costing you customers.
Common questions
- How do I know if my site is mobile-friendly?
- Open it on your own phone and try to use it — read the text without zooming, tap the buttons without missing, fill out a form. If any of that is fiddly, your customers are struggling too, and most of them are on phones.
- Does mobile-friendliness affect my Google ranking?
- Yes. Google primarily judges your site by its mobile version, so a site that's clumsy on phones can rank lower — on top of frustrating the majority of visitors who arrive on a phone in the first place.
