It isn’t just “does it fit on a phone screen”

It isn’t even one thing – there are a few different features, and a site can pass some and fail others.
Does the layout adjust to a smaller screen, or is it just the desktop site squeezed down, forcing people to pinch, zoom and scroll to read anything.

Can someone actually tap the buttons and links without accidentally hitting the wrong one, which happens constantly on sites designed with a mouse cursor in mind rather than a thumb.

Does it load quickly on a phone connection, which is often slower and less reliable than the office wifi it was probably tested on.

And is the text readable at normal size, rather than needing to be enlarged to make sense of it.

A site can look perfectly fine on the laptop you built it on and still fail on all four of these for the phone in your customer’s hand.

Why it matters

Someone who is struggling with your site to find your phone number, is a customer you’re pushing towards a competitor whose site just works. But there’s another reason this matters for getting found in the first place. Google tests and ranks websites primarily on how they perform on mobile, not desktop, regardless of how many of your visitors actually use a phone. This has been the case for some years now and a site that’s a pain to use on mobile is at a disadvantage in search results. Even for people who’ll go on to view it on a laptop. For Google’s purposes, the mobile version more or less is the real version.

Take a few minutes to check your site

The best check, and the first you should do, is to pick up your phone, go to your own website, and try to actually use it as a stranger would. Find your phone number and tap to call it, find your opening hours, try to fill in your contact form. Read a paragraph of your services page at the size it displays by default, without zooming in.

If any of that is awkward for you, someone who already knows the site well, it will be worse for someone landing on it for the first time.

For something a bit more concrete, Google has a free PageSpeed Insights test you can find by searching for it, where you paste in your web address and it tells you how well (and how quickly) your pages load and flags any technical issues you can pass on to your website support.

If something’s wrong, what actually fixes it

For sites built on WordPress, Squarespace, Wix or similar platforms, most themes are mobile responsive by default, meaning the layout will automatically adjust for different screen sizes rather than just shrinking.

If your site is a few years old and was built before this was standard, or has been added to bit by bit since, that’s often where the problems can accumulate. Old plugins, embedded videos, and tables can all be problematic when resizing from a desktop layout.
Sometimes the fix is really simple: an image set to a fixed width that doesn’t shrink, or is not needed at all in the mobile version. Or a menu that was never tested on a touchscreen. Other times, particularly on older sites, a proper mobile fix means a more thorough look at the whole template rather than patching individual pages.

Either way, this is a good example of something worth diagnosing before you spend money fixing it. Not every mobile problem needs a huge amount of work or a rebuild, so it’s worth running through these checks before committing to either a quick fix or a bigger piece of work.

Where to go from here

If everything checks out, that’s one less thing to worry about. If you found something that needs attention, it’s worth sorting it out – either yourself or by getting in touch for support.
