How to tell if your website is not mobile friendly
The signs are usually obvious the second you open your site on a phone. Text too small to read without pinching the screen, buttons so close together you keep tapping the wrong one, images bleeding off the edge. These aren’t minor annoyances. They’re signals that your site is actively failing most of the people who visit it.
Horizontal scrolling is another dead giveaway. If someone has to swipe sideways just to finish a sentence, they’ll close the tab in under five seconds. Slow load times on a mobile data connection make things worse.
The quickest way to confirm it is Google’s free Mobile-Friendly Test. Paste your URL in and you’ll get a specific list of what’s broken, not just a vague warning.
Why a website not mobile friendly hurts your business
More than 60% of all web traffic now comes from mobile devices. That means if your site doesn’t work properly on a phone, the majority of your visitors are getting a poor first impression before they’ve read a single word about what you do.
People leave fast. High bounce rates tell search engines your content isn’t satisfying visitors, which feeds directly into lower rankings. For small businesses competing for local customers, that’s a serious problem. We spoke to a plasterer in Manchester last year whose enquiry form was completely unusable on mobile. He had no idea. He’d been losing leads for months.
The most direct cost is lost enquiries. A potential customer who can’t tap your phone number or read your contact details on their phone will simply call someone else.
Common reasons your website isn’t mobile friendly
Most mobile problems trace back to one thing: the site was built when desktop was the only screen that mattered. That era ended around 2015, but plenty of older sites are still stuck in it.
Here are the most common culprits:
- Fixed-width layouts — the design is locked to a set pixel width that won’t flex for smaller screens.
- Tables-based HTML — an old coding method that creates rigid structure with no room to adapt.
- Non-responsive theme or template — the design framework simply wasn’t built to adjust across screen sizes.
- Unoptimised images — large files that overflow their containers and slow down mobile load times considerably.
- Third-party plugins or widgets — added features that were never designed with mobile in mind.
- Outdated CMS — older versions of platforms like WordPress may not apply modern responsive standards automatically.
Knowing which cause applies to your site matters. In many cases, patching individual issues ends up costing more in developer time than a clean rebuild would have.
What Google says about mobile-first indexing
Since 2020, Google has used the mobile version of your website as the primary version it reads and ranks. This is called mobile-first indexing. It applies to every site, old or new.
A site not optimised for mobile will rank lower in search results, even for searches made on a desktop. If someone in Leeds or York searches for your type of business, Google is far more likely to surface a competitor whose site works properly on a phone. Our team sees this pattern constantly when we audit sites for new clients.
For small businesses relying on local search visibility, sorting out a mobile problem is not something to put off until next quarter.
Your options for fixing a mobile unfriendly website
There are three realistic paths. The right one depends on how your site was originally built and how deep the problems go.
| Option | Best for | Typical effort | Cost range |
|---|---|---|---|
| Switch to a responsive theme | DIY platforms like WordPress or Wix with minor issues | Low to medium | £0–£200 |
| Hire a developer to recode | Custom-built sites with fixable layout issues | High | £500–£2,000+ |
| Full redesign with a professional | Outdated sites where patching costs more than rebuilding | Low for you | Varies — often most cost-effective long-term |
For many small businesses, a full redesign is the most sensible financial decision. Paying a developer £800 to patch a site built on outdated foundations can easily cost more than building a modern, mobile-first site from scratch, and you’ll likely be back to square one within two years anyway.
How we help small businesses get a mobile friendly website
At Quick to Web, our team works with small businesses and sole traders who are losing enquiries to a site that simply doesn’t work on mobile. Last month we rebuilt a joiner’s website in Leeds. Within three weeks of going live, he had six new quote requests through his mobile contact form, compared to zero the month before.
We offer free website design, so there’s no upfront cost for a brand-new site. We handle website hosting, ongoing maintenance, and support as part of a monthly fee from £29. You’re not left to figure things out alone after launch.
Every site we build is set up with local SEO in mind from day one. If you’re in Leeds, Bristol, Manchester, or York and want to know exactly where your current site is failing, get a free website review from our team today.
