The Ten-Second Green Flag Test

Buyers give a startup site ten seconds. Every green flag they check is a relevancy test, not a design test. What your site must prove before the tab closes.

By Philipp Rimmler

Ten seconds. That is the entire evaluation.

A founder listed what makes them trust a startup site, and not one item on it was a feature:

  • The first sentence says what the product does, in plain words
  • You can try it without creating an account
  • Real screenshots, not stock photos of people laughing at laptops
  • Public pricing
  • One-click reject on the cookie banner
  • They describe your problem before they describe themselves

Every one of those is a relevancy test, not a design test.

The last one does the most work. If a company states your problem accurately, you assume they have seen it before. That assumption sells harder than the demo video.

Most sites fail right there. They open on the company, the round, the category they invented. By the time the problem shows up, the tab is closed.

Ten seconds is not enough time to read a value prop. It is enough time to check whether someone is talking about you.

The free site audit runs this check with a scoring rubric behind it: four relevancy dimensions scored from your URL in 60 seconds. Run it on your homepage.
