How to tell if your website is not mobile friendly
The fastest way to check is free. Open Google’s Mobile-Friendly Test, paste your URL, and you’ll get a result in under 30 seconds. It flags specific issues, not just a vague pass or fail.
You can also spot trouble yourself. Text that’s too small to read without pinching, buttons that overlap each other, or a page that forces you to scroll sideways — these are all signs your site is broken on mobile.
Pull up Google Analytics and compare your bounce rate on mobile sessions against desktop. A big gap there usually means mobile visitors are landing and immediately leaving because something looks wrong. Not sure how to read it? Ask a friend to load your site on their phone and just watch what they do. The problems become obvious fast.
Why your website isn’t mobile friendly in the first place
Usually it comes down to age. Sites built before 2015 were typically designed around fixed pixel widths, meaning the layout was locked to one screen size and simply won’t bend to fit a phone. Responsive design only became standard practice several years after smartphones took off.
Other common causes include a missing viewport meta tag in the HTML. Without it, mobile browsers have no idea how to scale your page. Images that aren’t set to scale fluidly are another culprit, as are WordPress themes or plugins that were never built with phones in mind.
If your site runs on a custom-coded template or a CMS that hasn’t been touched in years, those structural decisions are baked in deep. Patching them one by one rarely solves the whole problem. We’ve seen sites where fixing one thing broke three others.
What a website that is not mobile friendly costs your business
Google uses mobile-first indexing. That means it ranks the mobile version of your site, not the desktop version. A poor mobile experience directly hurts your position in local search results, whether you’re based in Manchester, Bristol, or anywhere else in the UK.
Over 60% of all searches now happen on a mobile device, according to Statista’s 2024 data. If your site isn’t mobile friendly, you’re making a bad first impression on the majority of people who find you online.
When visitors have to pinch and zoom just to read a paragraph, most leave within seconds. That pushes your bounce rate up, which signals to Google that your page isn’t worth ranking, making the SEO damage worse over time. Your competitors with a properly built mobile site are taking that traffic instead.
Can you fix a mobile unfriendly website yourself?
Some fixes are genuinely within reach. Adding a viewport meta tag takes about five minutes if you’re comfortable editing HTML. Switching a WordPress site to a modern responsive theme can solve a lot of layout problems in an afternoon, though you’ll need to recheck your styling carefully afterwards.
Harder work includes replacing fixed-width tables, restructuring multi-column layouts, and resizing touch targets so buttons are easy to tap with a thumb. These changes can accidentally break your desktop layout if you’re not careful. Always test on multiple devices before publishing anything.
If your site is more than three years old or runs on a custom-coded template, a DIY patch is unlikely to fix the root issues. At that point, a professionally built mobile-friendly redesign is usually the more practical and cost-effective route.
| Fix type | DIY difficulty | Risk level | Best for |
|---|---|---|---|
| Add viewport meta tag | Easy | Low | Sites missing this one tag |
| Switch to responsive WordPress theme | Moderate | Medium | WordPress sites under 3 years old |
| Restructure fixed-width layouts | Hard | High | Developers only |
| Full mobile-friendly redesign | N/A (professional) | Low (managed) | Older or custom-coded sites |
What a proper mobile-friendly redesign looks like
A well-built site uses responsive layouts that adapt automatically to any screen size, from a small Android phone to a large tablet. You don’t need a separate mobile version of the site. One codebase handles everything cleanly.
Touch targets like buttons and links should be at least 44×44 pixels so they’re easy to tap with a thumb. Images should be served at the right size for each device so they don’t slow the page down on a mobile connection. Body text should sit at 16px or above — anything smaller and people are already reaching to zoom in.
Before launch, every page should be tested across iPhone, Android, and tablet. Browsers update regularly, so ongoing website maintenance matters too. A site that passes today’s test can develop new issues down the line without someone keeping an eye on it.
