How to Make a Landing Page to Validate Your Idea

Here's something most entrepreneurs learn the hard way: building a product people don't want is expensive and heartbreaking. Spending months (or years) on development, only to launch and hear crickets.

The smart approach? Validate your idea before building anything. And the simplest way to do that is with a landing page,one single page that describes your idea and measures interest.

You can create this today. No coding, no expensive tools, no complete product. Just a page that tests whether people actually want what you're thinking of creating.

Let me show you exactly how.

Why Validate Before Building

Maybe you have an idea for an app, a service, a course, a product, or a business. Before you invest serious time and money, you need to answer one critical question: will people actually pay for this?

A validation landing page helps you:

Test demand before building - Find out if people are interested before you spend months developing something.

Refine your messaging - See which benefits resonate and which get ignored.

Build an early audience - Collect emails from interested people who can be your first customers.

Save money and time - A landing page costs almost nothing compared to building a full product.

Get real data - Instead of asking friends "would you use this?" you're measuring actual interest from strangers.

The landing page approach has launched countless successful products. Companies like Dropbox famously validated demand with just a landing page and video before building their product.

What Goes on a Validation Landing Page

Your landing page needs just a few essential elements. Remember: you're testing interest, not making actual sales yet.

Headline (Clear and Benefit-Focused)

Your headline should immediately communicate what you're offering and why someone should care.

Not good: "Welcome to Our App" Better: "Send Unlimited Invoices Without Monthly Fees"

Or: "Learn Spanish in 15 Minutes a Day"

Or: "Get Fresh Meal Kits Delivered Weekly"

Make it specific. Someone should read your headline and know exactly what you're proposing.

Subheadline or Brief Description

One or two sentences that expand on your headline:

"Finally, invoicing software designed for freelancers. No subscriptions, no per-invoice fees, just simple billing tools you pay for once."

This is where you add just enough detail to clarify what you mean without getting wordy.

The Problem You're Solving

A short paragraph explaining the pain point:

"Freelancers and small business owners waste hours on invoicing and often pay $30-50/month for software with features they never use. Existing options are either too expensive or too complicated."

People need to see that you understand their problem. If they don't resonate with the problem description, your solution won't matter.

Your Solution (3-5 Key Benefits)

Bullet points or short paragraphs explaining how your idea solves the problem:

Simple invoicing in under 2 minutes
One-time payment, no monthly fees
Track payments and send reminders automatically
Works on any device
No complicated setup or learning curve

Focus on benefits (what the user gets) over features (what the thing does). "Save hours each month" is better than "Has automated recurring billing."

How It Works (Optional but Useful)

If your idea isn't immediately obvious, include 3-4 steps:

Create your invoice in minutes with our simple template
Send directly to clients via email
Get notified when they view and pay
Track everything in one dashboard

Keep it simple. You're showing it's easy, not explaining every feature.

The Call-to-Action (Most Important)

This is what you're testing. What do you want people to do?

Email signup - "Get notified when we launch" or "Join the waitlist"

Interest button - "Yes, I want this" or "Count me in"

Pre-order - If you're confident enough, "Reserve yours for $X"

Survey - "Tell us what features you need"

Your CTA should be a big, obvious button with clear text. This is what you're measuring,how many people are interested enough to click and give you their email.

If you've already talked to potential customers, include:

Quotes from people expressing interest
Number of people who signed up
Any press or mentions

But if you don't have this yet, that's fine. Not essential for initial validation.

FAQ (Optional)

Answer obvious questions:

When will this be available?
How much will it cost?
What platforms will you support?

Keep it brief. Three to five common questions is plenty.

Building Your Landing Page

Here's the step-by-step process to get your page live:

Step 1: Choose Your Tool

Several platforms make building landing pages easy:

Carrd - Perfect for this. Simple, affordable ($19/year), designed for one-page sites.

Wix or Squarespace - More robust but pricier monthly. Have landing page templates.

Unbounce or Leadpages - Designed specifically for landing pages. Professional but more expensive.

ConvertKit or Mailchimp - Email marketing platforms that include landing page builders.

Google Forms + Simple site - Ultra-minimal option: create a Google Form for signups and link from a basic site.

For most people testing ideas, I'd recommend Carrd. It's built for exactly this and costs almost nothing.

Step 2: Choose a Simple Template

Look for templates labeled:

Landing page
Launch
Coming soon
Pre-launch

Pick the simplest one. You want:

Clear headline at top
Space for bullet points or benefits
Email signup form
That's basically it

Avoid templates with too many sections or complex layouts. Simple means easier to build and easier for visitors to understand.

Step 3: Write Your Content

Before you start designing, write everything out:

Your headline
Your problem description
Your benefits
Your call-to-action

Write it in a doc first, get it clear, then copy it into your template. It's much easier to edit text in a document than directly in a website builder.

Step 4: Fill in Your Template

Copy your content into the template sections:

Headline at the top
Problem and solution in the main area
Benefits as bullet points or short sections
Big, obvious email signup form
Any FAQs at the bottom

Keep everything above the fold if possible,people should see the key message and the signup without scrolling.

This is crucial. You need to collect emails from interested people. Options:

Built-in forms - Many landing page builders have email collection built in.

Mailchimp or ConvertKit - Create a list and embed their form on your page.

Google Forms - Free and simple, though less elegant.

Gumroad - If you want to test with actual pre-orders.

Keep the form simple. Usually just an email address is enough. Maybe add a name field if you want to personalize follow-ups, but don't ask for too much information,every field you add reduces signup rates.

Step 6: Design Choices (Keep It Simple)

Colors - Pick one or two colors. Use one for your main button to make it stand out.

Fonts - Use the template's default fonts. Readability matters more than style.

Images - If you have a product mockup or relevant image, include one. If not, a clean text-based page works fine. Don't use random stock photos.

Button text - Make it action-oriented: "Join the waitlist," "Get early access," "Notify me at launch"

Professional doesn't mean fancy. Clean and clear beats complicated and flashy.

Step 7: Write Your Thank You Message

When someone signs up, show them a thank you message:

"Thanks for your interest! We'll email you as soon as we launch. In the meantime, follow us on Twitter @yourhandle for updates."

Set expectations for when they'll hear from you next.

What to Test and Measure

Once your landing page is live, you're gathering data:

Visitors

How many people visited your page? Get traffic from:

Social media posts
Relevant online communities (Reddit, Facebook groups, forums)
Friends and networks
Targeted ads if you have a small budget

You need at least 100-200 visitors to get meaningful data.

Conversion Rate

What percentage of visitors signed up? This is your key metric.

10%+ - Strong interest, probably worth building
5-10% - Moderate interest, might work with refinement
2-5% - Weak interest, needs rethinking
Under 2% - Little interest, probably not viable

These are rough guidelines. Context matters,a $1,000 product will have lower conversion than a free app.

Email Responses

After people sign up, email them with a question:

"Thanks for signing up! Quick question: what's the main problem you're hoping this solves for you?"

The responses will give you insight into what people actually care about.

Driving Traffic to Your Page

A landing page without visitors tells you nothing. You need to get people to see it:

Post in relevant communities - Find subreddits, Facebook groups, or forums where your target audience hangs out. Share your landing page (without being spammy) and ask for feedback.

Social media - Share on Twitter, LinkedIn, Instagram, wherever your audience is. Ask people to check it out and share if interested.

Friends and network - Your personal network is a starting point, but remember they'll be more likely to sign up out of politeness. You need stranger data too.

Content - Write a blog post or make a video about the problem you're solving, mention your upcoming solution.

Small ad budget - If you have $50-100 to spend, run some targeted Facebook or Google ads to your landing page.

Direct outreach - If you know people who fit your target audience, send them the link directly and ask for honest feedback.

You're not trying to go viral. You just need enough visitors to see if there's real interest.

Interpreting Your Results

After a week or two of traffic, analyze what you learned:

Good Signs

Conversion rate above 5%
Enthusiastic email responses
People asking "when will this be ready?"
Specific questions about features or pricing
People sharing your page with others

These suggest real demand. Consider moving forward.

Warning Signs

Low conversion rate (under 2%)
Traffic but no signups
Generic "looks interesting" responses with no real enthusiasm
Questions that reveal confusion about what you're offering

These suggest you might need to rethink the idea, messaging, or target audience.

What to Do Next

If validation is strong: Start building (or continue planning). Email your list with updates. Keep them engaged.

If validation is weak: Don't immediately give up. Test different messaging, target a different audience, or refine the idea based on feedback. Sometimes great ideas are poorly explained.

If there's no interest: Save yourself time and money. This particular idea, at least as presented, probably isn't viable. Better to know now.

Common Mistakes to Avoid

Too much information - Landing pages should be scannable. If you're writing paragraphs of explanation, you're probably overcomplicating.

No clear CTA - Make the email signup button impossible to miss. Big, bright, obvious.

Vague value proposition - "Revolutionary new app" tells nobody anything. Be specific about what you're offering.

Not driving traffic - You can't validate with 10 visitors. Get at least 100+ to see patterns.

Ignoring qualitative feedback - The numbers matter, but so do the comments and questions you get.

Waiting for it to be perfect - Your landing page doesn't need to be polished. You're testing, not launching. Ship something good enough and iterate.

The Investment

Creating a validation landing page is incredibly cheap:

Free option:

Free website builder (Carrd free plan, Google Forms)
Platform subdomain
Free email collection (Mailchimp free tier)
Total: $0

Small budget option:

Landing page tool: $10-20/month or one-time
Domain: $10-15/year
Email service: $0-10/month
Small ad spend: $50-100
Total: $100-200

Compare this to spending months building something nobody wants. The landing page is a tiny investment for massive risk reduction.

Moving Forward

A validation landing page isn't a guarantee of success, but it's one of the smartest moves you can make before investing serious time and money into an idea.

It forces you to articulate your idea clearly. It puts your hypothesis in front of real people. And it gives you data,not opinions from friends, but actual behavior from potential customers.

You don't need a fully built product to test demand. You don't need months of preparation. You need one clear page explaining what you want to build and a way for interested people to signal interest.

Build that page today. Write your headline, explain the problem and solution, add an email signup, and start sharing it. By next week, you'll have real data about whether your idea has legs.

And if the validation is strong? You've just found your first customers before you've even built the thing. That's the smartest way to start.
