Mobile-first design means we design your site for a phone screen before anything else, then make it work on bigger ones. For most local businesses that is simply where the customers are: standing in a flooded kitchen, sitting in the car outside a school, or scrolling on the sofa. Every Nerdsharks site has tap-to-call on every page and a call button that stays on screen as people scroll, so ringing you is always one tap away. If you use WhatsApp for work we can add a button for that too. Text is readable without pinching, buttons are big enough for a thumb, and forms ask for as little typing as possible.

## How it works

1. **Designed on a phone screen first** - We lay out every page for a small screen before a large one, so the important things, what you do, where and how to contact you, are near the top.
2. **Tap-to-call everywhere** - Your phone number is a tap-to-call link on every page, and a call button stays fixed on screen while people scroll.
3. **WhatsApp if you want it** - If you prefer messages to calls, we add a button that opens a WhatsApp chat with you, with a short opening line already filled in.
4. **Forms built for thumbs** - Fields bring up the right keyboard, choices are tap-to-pick instead of typed, and photos can be added straight from the camera.

## Why it matters

- **More calls from the same visitors** - When calling you is always one tap away, fewer people drift off to the next result while hunting for your number.
- **Easy in a hurry** - People searching on a phone are often stressed or short of time. A site that works well with one hand respects that.
- **Looks right everywhere** - Designing for the smallest screen first means the site holds together on tablets and laptops too, instead of the other way round.

## Questions

### Will my website work on mobile phones?

Yes, every Nerdsharks site is designed for phones first and then adapted for tablets and computers. We test it on real phone screen sizes before it goes live.

### Can customers call me straight from my website?

Yes, your phone number is a tap-to-call link on every page, and a call button stays on screen as people scroll, so calling you always takes one tap.

### Can I have a WhatsApp button on my website?

Yes, if you use WhatsApp for work we can add a button that opens a chat with your business number. You can have it alongside the call button or instead of it.

### Does a mobile-friendly site cost more?

No, mobile-first design is simply how every site is built, on every plan including Monthly at £99 a month. There is no separate mobile version to pay for.
