Mobile Friendly Website Check: How to Test and Fix Yours
Picture how someone actually finds you. They’re standing in a car park, or on a bus, or in your competitor’s doorway, and they’ve typed “electrician near me” into a phone held in one hand. They tap your listing, your site loads, and within about three seconds they’ve decided whether to ring you or go back and tap the next one.
That’s the real test. Not how the site looks on the 27-inch monitor it was designed on — how it behaves on a five-year-old Android with two bars of signal. For most local businesses the phone version isn’t a secondary view of the website. It is the website, and the desktop version is the afterthought. Here’s how to check yours honestly, and what to do about it if the answer is uncomfortable.
The five-minute check you can do yourself
You don’t need a tool for this. You need your own phone, off the wi-fi.
That last part matters more than anything else on the list. Testing at your desk on full-strength broadband tells you almost nothing, because the slow bit — downloading a page full of enormous photographs — happens instantly. Walk outside, turn wi-fi off, and load your own site over mobile data. Then work through these:
- Does it load before you get bored? Count it out. If you’re still looking at a blank white screen after five seconds, so is everyone else, and most of them have already left.
- Can you read the text without pinching? Body text should be comfortable at arm’s length. If your first instinct is to zoom, it’s too small.
- Can you hit the buttons with a thumb? Not a fingertip — a thumb, one-handed, while walking. Links crammed together in a row are the usual offender.
- Is the phone number tappable? Tap it. It should open the dialler with your number in it. If it just sits there as plain text, you’re asking a stranger to memorise eleven digits and type them in.
- Does anything scroll sideways? Swipe left and right. If the page slides horizontally, something on it is wider than the screen — usually a table, a wide image or an embedded map.
- Can you close the popup? If a newsletter box or cookie banner appears, find the X. If it’s off-screen or too small to hit, the site is now unusable and there is nothing the visitor can do about it.
- Is the important stuff visible without scrolling? What you do, where you do it, and how to contact you. On a phone screen that’s a very small amount of room, so it has to be the right small amount.
Anything that fails is worth fixing. Anything that fails badly is costing you calls right now.
Why this matters more than it used to
Two reasons, and neither is a fad.
The first is simply where people are. Local, urgent, “who can come out today” searches happen overwhelmingly on phones, because that’s the device in your hand when the boiler goes. A business that only works properly on a desktop has effectively closed the front door and left the back one open.
The second is that Google indexes the mobile version of your site by default. It’s not looking at your desktop layout and making allowances. If content is hidden, broken or painfully slow on a phone, that’s the version being judged — which makes this an SEO issue as much as a usability one, and worth reading alongside our plain-English guide to local SEO.
The usual culprits on older small-business sites
If your site was built more than a few years ago, or built cheaply, the problems tend to be the same handful.
| The problem | What it looks like on a phone | The fix |
|---|---|---|
| Fixed-width layout | The desktop site shrunk down, everything tiny, pinch-to-zoom required | Rebuild on a responsive layout — this is standard, not an extra |
| Huge unoptimised photos | Long white screen, then images appearing one by one | Resize and compress images before upload; modern formats help a lot |
| Tables and wide images | The page scrolls sideways | Let tables scroll inside their own box, cap image width to the screen |
| PDF used as a menu or price list | Opens in a separate viewer, unreadable without zooming | Put the content on an actual web page |
| Popups that can’t be closed | A cookie or newsletter box with no reachable X | Remove it, or make sure the close button is a proper thumb-sized target |
| Phone number as plain text | Nothing happens when you tap it | Make it a tel: link |
| Tiny navigation links | Fat-finger taps landing on the wrong page | Bigger tap targets, more spacing, a proper menu button |
Worth being blunt about one thing: “responsive” is not an upgrade you pay extra for. It’s the baseline of how websites have been built for over a decade. If a quote lists mobile compatibility as a paid add-on, that’s a flag.
Fix it, or start again?
Rough rule of thumb. If the site is fundamentally sound and the problems are photographs, a stubborn popup and a phone number that isn’t a link, that’s an afternoon’s work and well worth doing — the sort of thing a decent maintenance arrangement should cover, as we set out in what website maintenance costs.
If the underlying layout is fixed-width, you’re not fixing it. You’re propping it up. A site built to a fixed desktop width can’t be made responsive without rebuilding the layout, and the effort usually costs more than a fresh start. In UK terms a small business site typically runs somewhere in the £300–£1,500 range depending on scope and where you are in the country — the South East sits at the top end — which is often less than a year of patching something that was never going to work.
Here’s where we declare our interest, openly: Ready Set Web builds your site free from your Google Business Profile, mobile-first as standard, with a free .co.uk domain thrown in and £24 a month including VAT for hosting as the only cost. It’s live within 48 hours of the domain being registered. Here’s how it works.
Before you touch anything else
Whatever route you take, do the walk-outside-and-load-it test first. Not because it’s clever, but because it’s the only version of your website most of your customers will ever see — and it’s remarkable how many owners have never looked at it that way.
Once it loads fast and works with a thumb, the next question is whether the right things are on it at all. Our guide to what to put on a small business website covers that side of it.
