Today, many people use the Internet from their phones. In transport, in a queue, in the kitchen, before going to bed – the phone is always at hand. If your site is inconvenient on a smartphone, people will simply close it and never come back.

Why Mobile Convenience Is No Longer a Bonus, but a Must-Have

It's simple: if the site doesn't work properly on the phone, no one reads it. People won't look for a laptop to visit your site now - everything can be solved in a few clicks directly from a mobile phone.

What happens if the site is not adapted:

  • The person came in and immediately left.

  • Google noticed this and lowered the site in the search.

  • Less traffic, fewer orders, fewer chances to earn money.

And if everything works conveniently:

  • The user stays longer.

  • Transitions, calls, and purchases are growing.

  • The site looks modern and inspires confidence.

Responsive design is the foundation

No need to reinvent the wheel. Just make the site automatically adapt to any screen - phone, tablet, computer.

This is called adaptive design. It:

  • looks great on any device;

  • doesn't require a separate mobile version;

  • liked by Google (and that's really important).

If you make a website on WordPress, Tilda, Wix – choose themes that are already adaptive.

Image - don't overload

Big pictures are beautiful, but not when they take 10 seconds to load. If a page takes a long time to open, a person won't wait - they'll leave.

What to do:

  • Compress images before uploading (TinyPNG, Squoosh – works simply).

  • Use WebP – a modern and lightweight format.

  • Don’t push images from your camera without processing – they weigh 5–10 MB.

  • Don’t upload large images if they are still small on the screen.

Choose normal fonts

Small or fancy fonts look bad on a phone. It's hard for a person to read, their eyes get tired, and they just leave.

Simple rule: it must be readable.

  • Choose sans serif (i.e. simple, modern fonts).

  • No more than two fonts on a site - no need for chaos.

  • The font should be of sufficient size.

Here is a list of fonts that work well:

Font What does it look like?
Roboto ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz
Open Sans ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz
Lato ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz
PT Sans ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz
Montserrat ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz
Source Sans Pro ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz
Raleway ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz
Noto Sans ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz

These fonts are easy to find on Google Fonts and add to your website.

Flash — it's no longer fashionable and doesn't work

If you still have Flash somewhere on your site, delete it. It hasn't been supported in browsers for a long time, especially mobile ones.

Use HTML5, CSS animation instead, or remove this element altogether if it's not needed. In 2025, everything should be simpler and faster.

The site should be "light", not like a tank

On mobile Internet it may not be very fast. Therefore the site should open quickly - not weigh tens of megabytes, not "slow down".

How to make a website lighter:

  • Remove unnecessary scripts and plugins.

  • Use caching.

  • Connect a CDN (e.g. Cloudflare).

  • Optimize HTML, CSS and JS (on WordPress - Autoptimize or WP Rocket).

The faster the site, the better for the user and for Google.

Buttons - so you can press them with your finger

On the phone, everything is done with a finger. If the button is small, or there are several of them close together, it is difficult to press. And again: the user simply leaves.

Adviсe:

  • Large buttons - so you don't miss.

  • Enough space between them.

  • Don't put a bunch of links next to each other.

  • Menu - better "burger" (three stripes), convenient and not in the way.

Content for the phone – shorter, simpler, lighter

On mobile, no one reads "walls of text". If we see a long paragraph, we simply don't read it.

Which is better?:

  • Short paragraphs (2-3 lines).

  • More subheadings.

  • Indents, icons, blocks – separate information.

  • Simple text, no fluff.

Make it look like you wrote this text in another messenger.

Check the site on your phone

Once you've made a website, don't forget to check it out. Not only on your smartphone, but on different ones as well.

  • Check on iPhone, Android, tablet.

  • Go through all the pages: is it convenient to click, is it readable, is the design “off”.

Tools for verification:

  • Google Mobile-Friendly Test (publishes tips).

  • Responsinator – will show how the site looks on different devices.

  • BrowserStack – for detailed testing (paid, but convenient).
