Website Usability: What It Is, How to Test It and How to Improve It

Usability means how easy and pleasant it is for a person to use a website: to find what they need, understand the offer and complete an action without effort and mistakes. Website usability directly affects leads and sales: an inconvenient website loses customers even if ads and SEO work. One thing matters: usability is not the same as design. A beautiful website can be inconvenient, and the other way around.

Why usability matters for business

• It affects conversion. The fewer obstacles on the way to a request, the more people leave one.
• It reduces bounce. A visitor who immediately understands what is where stays on the website longer.
• It builds trust. A clear, predictable website feels reliable.
• It reduces the load on support. Fewer questions about “where to find this” and “how to order”.
• It supports SEO. Search engines take behavioral signals into account, and a convenient website more often gives positive ones.

Many of the problems we described in the article “Why your website doesn’t sell” start with usability, and how to measure the return is covered in “How to measure website ROI”.

Signs of good usability

1. Clarity. Within a few seconds it is clear what the website offers and for whom.
2. Simple navigation. Menus are short and logical, and the right section is found in one or two clicks.
3. Speed. Pages open without a long wait. How to improve this is described in our website speed service.
4. Convenience on a phone. Buttons are large enough, text is readable without zooming and forms are easy to fill in. More on this in the article “Mobile adaptation”.
5. Readability. Sufficient font size, contrast, short paragraphs and subheadings.
6. Consistency. The same elements look and work the same on every page.
7. Clear actions. Buttons are labeled specifically (“Book a consultation”), not generally (“Next”).
8. Simple forms. Only the necessary fields and clear error messages.

Common usability problems

• an overloaded menu with dozens of items;
• an unclear statement of the offer on the first screen;
• long forms and required fields that are not really needed;
• pop-ups that cover the content;
• a poor mobile version: tiny text and buttons that are hard to reach;
• a complicated checkout with several unnecessary steps;
• contacts that are hard to find.

How to test website usability

1. The five-second test. Show a page to a person for five seconds and ask what the website offers. If the answer is inaccurate, the problem is the first screen.
2. Walk the customer path yourself. Complete the key scenarios: find a service, leave a request, place an order. Note where delays appear.
3. Run testing with real people. Ask a few people to complete tasks on the website and watch without hinting. Even a small group reveals most problems.
4. Look at analytics. Bounce, user paths, exit pages and the places where visitors get stuck in the funnel.
5. Use click maps and session recordings. They show where people click and where they get lost.
6. Check on different devices. Phone, tablet, different browsers and screen sizes.
7. Collect feedback. Customer questions and complaints often point to weak spots better than any report.

What to improve first

You do not need to fix everything at once. Start with the places that affect leads the most:

• First screen. A clear offer and a visible action button.
• Navigation. Shorten the menu and make the path to a request shorter.
• Forms. Remove extra fields and add clear hints.
• Mobile version. Check whether the key action can be completed with one thumb.
• Speed. Optimize the heaviest pages and images.

If there are many problems and point fixes do not help, it may be time for bigger changes. We describe the signs of such a situation in the article “5 signs your website urgently needs a redesign”.
