The one-sentence test for your agency’s offer

Test your agency’s positioning with one sentence: explain what you do, why it matters, and why the right customer should stop to learn more.

THE CORE IDEA

A clear agency offer tells the right customer what you do and why it matters. Try this trade-show test: you have one sentence to make that person stop and ask for more.

The trade-show test

You need an offer SO compelling that people feel stupid saying no to it.

Here’s one of my favorite tests:

Imagine you’re standing at a crowded trade show.

Your ideal customer is walking past you.

You get one sentence to make them stop.

What do you yell?

That sentence should explain what you do, why it matters, and make the right person want to know more.

If your offer takes five minutes to explain, it’s not sharp enough.

Write your one-liner

What’s your one-liner?

Write down the sentence you’d yell across the trade show floor. Then test the demand behind it: a clear offer still needs a customer willing to pay.
