The five-second homepage test: can a stranger tell what you do?

In 2006, a team of researchers led by Gitte Lindgaard showed people web pages for just 50 milliseconds, about a twentieth of a second. Their judgements of those pages lined up closely with the judgements people made after looking for longer. In other words, first impressions form almost instantly, and they tend to stick.

Nielsen Norman Group, one of the most respected usability research firms, found something similar about attention. People often leave a web page within 10 to 20 seconds. Pages that clearly communicate their value can hold attention for much longer, but you have to make that value clear within about 10 seconds.

Both studies are more than a decade old, and they still hold up because they describe how people behave, not how websites looked at the time. Your homepage has a few seconds to earn the next few minutes.

1. 1What do you do? In plain words, not a slogan. "Commercial HVAC and plumbing repair in Calgary" beats "Excellence in every system."
2. 2Who is it for? Visitors need to see themselves. Name the industries, business sizes or situations you serve best.
3. 3What should I do next? One obvious next step, like booking a call or getting a quote, repeated down the page.

Notice what's missing from that list: your history, your values and your awards. Those things matter, but they're supporting evidence. They belong lower on the page, after you've answered the three questions.

You don't need software or a budget. You need five people who don't know your business well. A friend of a friend, a neighbour or someone from another department at a partner company all work.

1. 1Open your homepage on a laptop or phone and let them look for five seconds. Use a timer.
2. 2Close the page or turn the screen away.
3. 3Ask three questions: What does this company do? Who is it for? What would you click first?
4. 4Write down their answers word for word, without correcting them.
5. 5Repeat with the next person, then compare the answers with what you hoped they would say.

That job-site detail is easy to miss. If your customers find you while standing next to a broken boiler, your homepage needs a phone number they can tap with one thumb. Clarity isn't only about words. It's about understanding the moment your customer is in.

• A slogan instead of a sentence. Clever lines are hard to repeat and easy to forget.
• Talking about yourself first. "We are a family-owned company founded in 1998" tells visitors nothing about their problem.
• Too many choices. Five buttons at the top of the page usually means none of them gets clicked.
• Hiding the next step. If booking a call means scrolling to the footer, many visitors won't bother.
• Stock photos of strangers. Real photos of your team and your work build more trust than smiling models.

If your test results were mixed, start with your message. A homepage can only be as clear as the sentence behind it. Our guide to telling one story everywhere walks through how to write that sentence, and the Brand Clarity Checklist has a full section on your homepage.

A homepage rewrite is also one of the five deliverables in the Marketing Reset. We write conversion-focused copy that shows visitors what you do within five seconds, based on the customer profile and message we build with you first.
