Why your website is not converting: 7 causes you can see in 5 seconds

Key takeaways

• A website that does not convert usually fails in the first five seconds: the visitor does not understand what is offered, for whom, or what to do next.
• Visitors often leave a page within 10 to 20 seconds unless the value is clear, according to Nielsen Norman Group, so the first screen decides most of the outcome.
• The seven causes below are visible without analytics. Show your first screen to a stranger for five seconds and ask what they saw.
• Fix the words first. The headline and the button label are the cheapest fixes and the ones with the largest effect.

What “not converting” means

A website converts when a visitor takes the action the page asks for: a purchase, a signup, a booked call. A website that is not converting gets visits and little else.

A benchmark tells you how far off you are. Unbounce analysed more than 57 million landing page conversions and found a median conversion rate of 6.6 percent across industries. A page far below the figure for its sector has a problem on the page, not in the traffic.

This guide covers the first five seconds, when a stranger decides whether your page is worth reading. Forms and checkout come after that moment.

The seven causes you can see in five seconds

Jakob Nielsen found that visitors often leave a web page within 10 to 20 seconds, unless the value is clear, and 57 percent of viewing time lands above the fold. All seven causes live in that first screen.

1. The headline does not say what you sell

• What you see. A slogan in the place of a description. “Work smarter, not harder” above a time-tracking app.
• Why it costs you. Nielsen Norman Group found that 79 percent of test users scan a new page; only 16 percent read word by word. A scanner reads the headline and little else.
• The fix. Name the product and the job in the headline, in words a stranger uses. “Time tracking for freelancers who bill by the hour.”

2. Nobody can tell who it is for

• What you see. A page that speaks to everyone: businesses, teams, professionals. No sector, no size, no role.
• Why it costs you. A visitor who does not recognise themselves assumes the offer is for someone else.
• The fix. Put the audience in the headline or the line under it. One audience per page. If you serve three, make three pages.

3. The benefit is missing

• What you see. Features, integrations and a product category, but no sentence about what changes for the visitor.
• Why it costs you. The visitor understands what the thing is and still has no reason to act. “An invoicing platform” is a category. “Get paid two weeks sooner” is a reason.
• The fix. One line under the headline that names the outcome, with a number where you have one.

4. The button does not stand out, or there are two

• What you see. A main button in the same colour as the navigation, or two buttons of equal weight: “Book a demo” next to “Start free trial”.
• Why it costs you. The visitor does not see the next step, or has to choose between two.
• The fix. One primary button in the accent colour, with a label that says what happens next. “Start my free trial”, not “Submit”.

5. The image carries the message and the text does not

• What you see. A product screenshot or a photo that explains the offer, next to a headline that does not. Cover the image and the page says nothing.
• Why it costs you. Images load last, get cropped on phones, and are skipped by screen readers and by AI assistants. The words have to stand alone.
• The fix. Write the headline so it works without the image. Then let the image show the product, not a stock photo of a handshake.

6. Nothing on the first screen says you are real

• What you see. No client names, no numbers, no photo of a person, no address. Proof sits three screens down, if it exists.
• Why it costs you. Stanford’s Web Credibility guidelines, built on research with more than 4,500 people, put “show that there is a real organisation behind your site” at the top of the list.
• The fix. One line of proof near the button: a client count, a named customer, a rating, or a photo of the founder with a name.

7. Something is in the way

• What you see. A cookie banner over the button, a pop-up before the first line is read, a video that autoplays, or a page that is still loading when the five seconds are up.
• Why it costs you. The BBC lost 10 percent of users for every extra second of load time, as reported by Nielsen Norman Group. A pop-up spends the visitor’s seconds on something they did not come for.
• The fix. Load the first screen first. Delay every pop-up until the visitor has scrolled. Keep the cookie bar at the bottom and out of the way of the button.

The seven causes at a glance

Cause	Five-second question that catches it	Fix time
1. Headline names no product	What does this company offer?	An hour
2. No audience	Who is it for?	An hour
3. No benefit	What would you get from it?	An hour
4. Weak or doubled button	What would you click first?	An hour
5. Text does not stand alone	Does the text work without the image?	Half a day
6. No proof	Do you believe them?	Half a day
7. Something in the way	Did you see the page at all?	A day, with a developer

The first four are the four questions of a five-second test. They are also the cheapest fixes on the list: words, not design.

What to do first, by type of site

If you run a SaaS page

Start with causes 1 and 4. Software headlines drift to slogans, and most SaaS heroes carry two buttons. Name the product in the headline and demote the second button to a text link.

If you sell a service

Start with causes 2 and 6. Service pages speak to everyone and hide the people behind the company. Name the client you serve, and put a face and a client count near the button.

If you run a shop

Start with causes 3 and 7. Shops lead with products, forget the reason to buy here, and load slowly. Add one line that says why this shop, and time the first screen on a phone.

When the first screen passes and the page still does not convert

Then the problem sits below the fold or on another page. Baymard Institute puts the average documented cart abandonment rate at 70.22 percent, lost in checkout, not in the hero section. A conversion optimisation audit walks the whole journey. The Above the Fold Audit (€249) covers the first screen of about 15 key pages.

Frequently asked questions

Why does my website get traffic but no sales?

Because the visitors who arrive do not understand the offer fast enough to act. Run a five-second test on the page your ads land on. If strangers cannot say what you sell and for whom, the page loses them before the sales argument starts.

What is a good conversion rate for a website?

Unbounce’s benchmark puts the median landing page conversion rate at 6.6 percent, with large differences per sector. Compare against your sector figure and against your own page last quarter.

Can I fix a website that is not converting without a redesign?

In most cases, yes. Five of the seven causes are words: the headline, the line under it, the button label and the proof line. Change the words first, test again, and redesign only if that did not move the result.

How long should it take a visitor to understand my website?

About five seconds. People judge a site’s look within 50 milliseconds, per research summarised by Nielsen Norman Group, and leave within 10 to 20 seconds when the value is unclear. Five seconds covers a headline and a button, which is all a scanner reads.
