Does Your Website Look Bad on Mobile? You Are Losing 70% of Your Customers

In 2025, sitting in front of a computer to browse for leisure or to look for a restaurant is almost a rarity. We do everything from the sofa, the subway, or walking down the street, with the mobile in hand.

However, many companies still design their websites looking at a large desktop screen. Mistake.

The statistics are overwhelming: in most B2C sectors (restaurants, renovations, clinics, shops), between 70% and 80% of traffic is mobile. If your website doesn’t work perfectly on an iPhone or an Android, you are ignoring the vast majority of your audience.

The Tyranny of the Thumb

Mobile design is not just “making everything smaller”. It requires a different mindset: touch usability.

The mobile user is impatient and navigates with their thumb.

• Large Buttons: They must be easy to tap without making mistakes. Nothing is more frustrating than trying to hit a tiny link and opening the one next to it.
• Accessible Menus: The “hamburger” menu must deploy smoothly and be easy to close.
• Direct calls: When someone sees your phone number on the web, they want to tap it and call. If they have to memorize it or copy and paste, you have lost them.

Mobile-First Indexing: Google is watching you

For several years, Google has applied the “Mobile-First Indexing” policy. This means that Google, to decide what position you appear in the search engine, examines the mobile version of your web, not the desktop one.

Even if your website looks beautiful on your 27-inch computer, if the mobile version loads slowly, has unreadable text, or elements that go off-screen, Google will penalize you and send you to page 10.

Test it yourself

Take out your mobile right now and go to your website. Be honest:

1. Does it take more than 3 seconds for something to appear?
2. Do you have to “zoom” with your fingers to read the text?
3. Can you tap the buttons comfortably with one hand?

If the answer to any of these questions is negative, you need an urgent renovation. Your website is not broken, it is simply living in the past.
