How to test if your positioning really works

Written by Graham Charlton | 11 September 2025

Every startup founder thinks they have a clear, compelling story. 

However, most positioning falls flat outside the founder’s head. What makes perfect sense to you often lands as vague, confusing, or indistinguishable to your customers.

Strong positioning is about clarity, resonance, and proof. And the only way to know if your message is working is to test it.

In this guide, we’ll walk through five practical ways to validate your positioning and messaging, from quick litmus tests to deeper customer research. 

By the end, you’ll know whether your story is landing, or whether it’s time to sharpen, iterate, or overhaul it.

Why testing your message matters

Bad positioning is expensive. It drives up customer acquisition costs, slows sales cycles, and forces you to rely on discounts or persuasion to get deals over the line. 

Good positioning does the opposite by helping people instantly understand why you matter and why you’re different.

“Customers need to quickly understand what you are, why they should care, and why you are different from the alternatives.” - April Dunford, author of Obviously Awesome

If you can’t answer those questions in the language your customers understand, your startup will struggle to grow.

You can’t just believe your positioning works; you need evidence.

1. Ask five clarity questions

Start with the basics. If your positioning is clear, you should be able to answer these five questions in one or two sentences each:

  1. Who is this for? (Your target customer.)
  2. What problem are you solving?
  3. What’s your solution?
  4. Why is it better or different?
  5. Why should they care now?

If you stumble or drift into jargon, your positioning isn’t ready.

Try running this exercise with your leadership team and your sales or customer-facing staff.

If everyone gives wildly different answers, that’s a red flag. You need internal alignment before you can achieve clarity outside..

2. Run the 30-second stranger test

This is the simplest and most brutal test you can do. 

Take your homepage, pitch deck, or one-liner and put it in front of someone who knows nothing about your business. Give them 30 seconds to read or listen. Then ask:

  • What do we do?
  • Who is it for?
  • Why does it matter?

If they can’t answer accurately, your message isn’t working.

A Nielsen Norman Group study found that users often leave webpages within 10–20 seconds if they don’t find a clear value proposition. That’s how little time you really have.

If a stranger can’t get it in 30 seconds, your prospects won’t either.

3. Listen to your customers

Customer interviews are one of the fastest ways to test your positioning. 

Listen for how they naturally describe your product, problem, or value.

  • What words do they use when explaining the problem?
  • How do they describe your product back to you?
  • Do they frame benefits in terms of speed, cost, trust, or something else?

Slack famously found traction when it shifted from ‘a tool for teams’ to ‘be less busy’. 

This was a phrase that echoed how users described its value.

Use feedback to refine your messaging in the same language your audience already trusts.

4. Collect sales and support feedback

Your sales and support teams are on the frontlines. If positioning isn’t working, they’ll know first.

Ask them:

  • Which parts of the pitch resonate? Which are falling flat?
  • What objections come up most often?
  • Do prospects get it quickly, or does it take too long to explain?

HubSpot, for example, constantly iterates its messaging based on feedback loops from its sales reps. The result is positioning that matches real conversations, not just marketing theory.

5. Test with data, not just opinions

Qualitative feedback is powerful, but you also need quantitative signals. Use your digital touchpoints as a lab:

  • Landing pages. Test different headlines or value props. Track bounce rates and conversion lifts.
  • Ad copy. Run A/B tests with different positioning angles to see which messages drive clicks.
  • Email subject lines. Check open and reply rates on messaging variations.

For example, if a landing page with ‘Save time and money’ outperforms one with ‘Streamline collaboration,’ that’s data on what resonates most with your audience.

When to iterate and when to overhaul

Not every messaging tweak requires a total reset. Use this rule of thumb:

  • Iterate if your core audience and product are stable, but your language isn’t landing. Small refinements can sharpen clarity.
  • Overhaul if you’ve pivoted product, target market, or business model. In that case, your old positioning is dead weight.

Think of positioning as a living system, not a one-time project. 

Markets shift, competitors emerge, and customer needs evolve. If you’re not reviewing and testing regularly, you risk slipping into irrelevance.

Summary

Clear messaging drives growth; unclear messaging hinders it. 

Test fast, listen to customers, and use data to decide whether to tweak or reset. The sooner you validate your story, the sooner others will believe it.
