How to check if your website actually works on a phone in 10 minutes

A florist in Fountain Square showed me her website on her phone three weeks ago. She had it redesigned six months earlier, paid a local firm $3,200 flat rate. I asked if she had ever tried to contact herself through it.

She hadn't.

We pulled it up on her phone. The gallery loaded. The About page loaded. The "Contact us" button led to a six-field form. She filled it out, hit Submit, and we watched the page go blank.

No confirmation message. No email arrived. The form had been sending leads to nowhere for at least six months, probably longer.

That's the extreme version. But smaller failures, a phone number that won't dial when you tap it, a nav menu that opens on desktop and freezes on mobile, hours buried three scrolls past the footer, show up on probably half the small business sites I look at. The shop owner just doesn't see them because they're not checking on a phone.

Here's a six-check audit you can do right now, on your own phone. No developer, no tools, no budget required.

The six checks

Check 1: Can you read it without zooming?

Open your website on your phone and set it down on a table. Can you read your business name without picking it up and pinching the screen?

Text should be legible at arm's length. Buttons should be large enough to tap with a thumb, not the corner of a fingernail. If you're squinting at your own homepage, every customer who lands on it is squinting too.

If the text is tiny and the layout looks like a shrunken desktop page, your site probably isn't built responsively. That's a structural problem, not a settings tweak.

Check 2: Tap the phone number

Find your phone number on the page. Tap it.

Did your phone offer to dial it? Or did nothing happen?

A phone number that doesn't trigger a call when tapped isn't a phone number. It's a picture of one. A customer standing in a parking lot at 6 PM won't troubleshoot it. They'll call whoever comes up next in search.

The fix is a tel: link: <a href="tel:+13175550000">317-555-0000</a>. On Squarespace, Wix, or most managed platforms, look for the link field in the button or text settings and change it from a URL to a phone number. Two minutes for a developer, sometimes two minutes for you.

Check 3: Open the navigation menu

Tap the menu icon, usually three horizontal lines in the corner. Does it open? Does it close when you tap again? Do all the links in it go somewhere real?

Menus that work on a 27-inch monitor and break on a phone are common. Developers test on what they build on. Nobody tested it on a 6-inch screen at arm's length.

Tap every nav link. Confirm each one loads a real page.

Check 4: Submit your own contact form

Fill out the contact form on your site. Use your real email address. Include a note. Hit Submit.

Check two things: did a confirmation message appear on the page? And did an email arrive in your inbox? Check your spam folder too.

If nothing came through, your form is broken. Every submission over however long that form has been live has disappeared. This is the most common invisible problem I find on small business sites, and it's almost always fixable in under an hour.

Check 5: Find your hours in 15 seconds

Set a timer. Open your site on your phone. Find your hours.

If it takes more than 15 seconds or more than three taps, it's too long. A customer standing on the sidewalk outside your door at 5:45 PM is not going to spend 30 seconds looking. They'll check your Google Business Profile instead, and if that's incomplete, they'll move on.

Hours belong on the homepage or one tap away. Not inside a footer. Not under "About" on a subpage called "Visit us."

Check 6: Turn off Wi-Fi and reload

Switch to mobile data only, turn off Wi-Fi in your phone settings, then open your site.

Does the page load in under 3 seconds? Or does it sit there for 5, 8, 10 seconds while images slowly trickle in?

According to Google's mobile page speed benchmarks, 53% of mobile visitors leave a page that takes longer than 3 seconds to load. A hair salon in Fishers competing against six others in Maps results cannot afford a 9-second load time on cellular.

The most common cause is uncompressed photos. A homepage hero image uploaded at 4MB could be 180KB with no visible quality difference. This is a free fix on most platforms, or a 20-minute job for someone who knows what they're doing.

What to do when something fails

If the contact form is broken, email whoever manages your site and describe what happened specifically: "I filled out the form on [page], hit Submit, and received no confirmation email." That's enough detail to find and fix it. If you're paying a monthly maintenance fee and this was missed, say so plainly.

If the phone number doesn't dial, ask them to wrap it in a tel: link.

If the site is slow, ask about image compression. If they can't explain specifically what they'd compress and why, that's useful information.

If the whole site looks broken on mobile, tiny text, sideways layout, images overflowing the screen, it may not be responsive at all. Google moved to mobile-first indexing in 2024, which means a site not designed for phones ranks worse in search, not just looks worse. A non-responsive site in 2026 should be replaced, not patched.

Most shop owners haven't looked at their own website on a phone in over a year. Pull yours up tonight on mobile data. You might find that the thing quietly costing you business isn't your location, your pricing, or your marketing. It's a form that's been broken since the last redesign.
