What Makes a Website Easy to Use?

A website is easy to use when a visitor finds what they came for in a few seconds, without thinking. That comes down to three choices: headings people can scan, one clear next step on every page, and a layout that works with a thumb on a phone. Then you test it. You do not need a lab or a budget. A phone and a friend are enough.

People scan, they do not read

Visitors look for the one thing they came for and skip the rest. In a well-known study by Nielsen Norman Group, 79 percent of test users always scanned a new page, and only 16 percent read word by word. So use clear headings. Keep your paragraphs short. Put the important thing near the top of the page. If someone has to hunt for it, they leave and try another site.

One clear next step per page

Every page should have one main thing to do. Call you. Book a time. Place an order. Ask for a quote. When you put three buttons of the same size next to each other, people freeze. Pick the step that matters most and make it stand out. You do not have long. Nielsen Norman Group found that people often leave a page in 10 to 20 seconds, so say what you offer in the first 10.

Make it work with a thumb

Many of your visitors are on a phone. Text needs to be large enough to read without zooming in. Your phone number should be tappable. And buttons need to be big enough to hit on the first try. The accessibility standard WCAG 2.2 sets a minimum of 24 by 24 CSS pixels for most things you tap, with a few exceptions such as links inside a sentence. Google's web.dev guidance recommends about 48 pixels, roughly 9 mm, with about 8 pixels of space between targets. Nielsen Norman Group says at least 1 cm by 1 cm. Bigger is safer.

Check it yourself in an afternoon

You can find most problems without special tools. Do these checks in order, and write down every spot where you or someone else got stuck.

  1. The phone test. Open your site on your own phone, not your computer. Try the one thing a customer comes to do, like finding your hours or booking a time. Count the taps. Note anywhere you had to zoom in, or tapped the wrong thing.
  2. Tap your phone number and your email address. Each one should open your phone app or your email app straight away.
  3. The five-second test. Show your home page to someone who does not know your business for five seconds, then put the phone away. Ask what you do, where you work, and how to reach you. If they cannot say, your top of the page needs work. Nielsen Norman Group says a page has about 10 seconds to make clear what you offer, so the top of the page has to answer these fast.

  4. Watch a friend use it. Give them one real task, like "find out if they serve my town and ask for a quote". Ask them to think out loud as they go. Do not help and do not explain. Just watch and take notes. See: Thinking Aloud: The #1 Usability Tool (opens in a new tab)
  5. Repeat with a few more people, up to about five. Nielsen Norman Group recommends small tests with no more than five people, run as often as you can. See: Why You Only Need to Test with 5 Users (opens in a new tab)
  6. Run your home page through PageSpeed Insights and look at what it says slows the page down. See: PageSpeed Insights (opens in a new tab)
  7. Fix the problem that tripped up the most people first. Then test again with someone new.

Common questions

What makes a website easy to use?

A website is easy to use when visitors find what they came for in a few seconds. Clear headings, short paragraphs, one obvious next step on each page, and buttons big enough to tap with a thumb. If a visitor has to hunt for your phone number or prices, the site is working against you.

How can I test if my website is easy to use?

Open your site on your own phone and try to do the one thing a customer would do, like book a time or find your hours. Count the taps. If it takes more than a few taps or you have to zoom in to read, your visitors are struggling too. Then ask a friend to try it and think out loud while you watch. A handful of people is enough to find most problems.

What are the most common website usability mistakes?

Common mistakes are too many choices on one page, text that is too small on a phone, buttons too small or too close together to tap, slow loading photos, and hiding the main action below a wall of words. Each one makes a visitor think harder. Every extra bit of thinking is a chance for them to leave.

The takeaway

An easy website does not make people think. Say what you do, show one clear next step, and make all of it work with a thumb. Then hand your phone to a friend, watch quietly, and fix what trips them up.
