The short answer
A landing page test checks demand by describing your product on one page, with a price and a single call to action, before it exists. Send at least 100 people who have the problem to it, then count what they do. Around 4% leaving an email is promising; 10% or more, with clicks on paid plans, is strong.
What a landing page test is
A landing page test is the simplest real test of a business idea. You build one page that describes the product as if it were ready, show a price, and ask visitors to do one thing: leave an email, choose a plan or pre-order. Then you send people who have the problem to it and count what they do.
It sits between talking to people and building a product. Conversations tell you a problem is real. A landing page tells you whether people act when they see your solution and its price. It takes a day to build, needs no code, and gives you numbers instead of opinions.
What to put on the page
- A headline that names the problem
- Use the words your customers use. If people write “chasing late invoices”, say that, not “accounts receivable automation”.
- A short explanation
- Two or three sentences on what the product does and the result people get. Skip the feature list.
- Proof that you understand
- A line or two that shows you know their situation, such as the workaround they use today and why it falls short.
- A price
- Show it, even though nothing is for sale yet. Two or three plans tell you more than one.
- One call to action
- Leave an email, choose a plan or pre-order. Pick one main action and make it obvious.
- Nothing else
- No menu, no blog, no links away. Every extra click is a way to leave without deciding.
Who to send to it
The test is only as good as its visitors. Friends, other founders and people who clicked a vague ad will give you misleading numbers. You want people who have the problem, ideally people who described it themselves recently.
- People who asked for a fix
- Posts and comments where people describe the problem. Reply helpfully, and share the page when it's relevant and the community allows it.
- Communities for that group
- Forums, subreddits and groups where people with the problem gather.
- Direct outreach
- Short, personal messages to people who wrote about the problem, referring to what they said.
- A small ad budget
- Targeted search or social ads. Fast, but ad visitors usually convert worse than people who asked, so judge them separately.
How many visitors you need
Aim for at least 100 real visitors before you read the numbers. Below that, a single sign-up moves the rate by a whole percentage point or more, and the result is mostly luck.
More is better if you can get it, especially if you want to compare two headlines or two prices. And count real people only: filter out bots, which can be a large share of the traffic on a new page, and your own visits.
Which numbers mean yes
These are the thresholds Ghostlaunch's 7-day reports use. They're starting points, not laws, and they'll differ by price and audience: a $2,000-a-year business product can work with lower rates than a $5 app.
| What visitors did | Verdict |
|---|---|
| Fewer than 100 real visitors | Not enough data yet |
| Under 4% left an email | Weak: change something and test again |
| 4% to 10% left an email | Promising: talk to the people who signed up, then test the price |
| 10% or more left an email, and at least 40% of plan clicks were on paid plans | Strong: start building for the people who signed up |
When visitors come but don't act
If plenty of people visit but few act, more traffic won't fix it. Look at the page and the audience first: does the headline use customers' words, is the price clear, are these visitors people who have the problem? Then change one thing and test again.

Running the test for 7 days
A week is long enough to reach 100 or more visitors with steady outreach, and short enough that you don't fall in love with the idea. A simple plan:
- Day 1: write the headline and copy from the words in real posts. Build the page with a price and one call to action.
- Day 2: check it on a phone, set up visit and click tracking, and show it to five people who have the problem for a first reaction.
- Days 3 to 6: share the page where people with the problem are. Reply to everyone who signs up and ask what made them do it.
- Day 7: count real visitors, sign-ups and plan clicks. Compare them with your target and decide: build, change or drop.
Questions
What is a landing page test?
A landing page test checks demand for an idea by describing the product on a single page, with a price and one call to action, before the product exists. You send people who have the problem to the page and measure how many leave an email, choose a plan or pre-order.
What is a good conversion rate for a landing page test?
It depends on price and audience, but as a starting point, 4% of real visitors leaving an email is promising and 10% is strong, measured over at least 100 visitors. Clicks on paid plans count for more than free sign-ups, because they show people considered paying.
How much traffic do I need to validate an idea?
At least 100 real visitors who have the problem, and more if you're comparing versions. With fewer, one or two sign-ups swing the result. The quality of visitors matters more than the count: 100 people who asked for a fix beat 1,000 from a broad ad.
Should I show a price on a validation landing page?
Yes. Without a price, a sign-up only shows curiosity. With one, it shows people considered paying that amount. Two or three plans are even better, because which one people choose tells you about willingness to pay. Explain honestly after the click that the product isn't ready yet.
What tools do I need for a landing page test?
Any page builder with a form, and analytics that count visits, clicks and sign-ups. Many website builders do both. Or skip the setup: Ghostlaunch builds the page, reaches people already asking for a fix and sends a report with a verdict after 7 days.
