Overview

Audit any landing page above the fold in 15 seconds. 6 checks show what a first-time visitor sees.

Your visitors decide in 5 seconds whether they stay or leave. 5sec.io shows you what they see in that time. Click the icon on any page, then click Start scan. The extension reads the part above the fold, takes a screenshot, and grades it on the six questions every first-time visitor silently asks: 1. What is it? Does the headline say what the product actually is? 2. Who is it for? Can a stranger tell if this page is meant for them? 3. What do I get? Does the fold promise an outcome, or only describe the product? 4. What do I do? Is there one obvious next step? 5. Does the text stand alone? Do the words carry the message without the imagery? 6. Does the image help? Does the hero image reinforce the headline? Each check gets a pass or fail, one sentence of evidence, and a concrete fix when it fails. Results arrive in about 15 seconds. Use it on your own landing pages before you launch, or on a competitor's page to see how they compare. Free tests: 2 per month without an account, 5 per month with a free account. Credit packs are available for more. What the extension sends to our servers: the page URL, the visible text above the fold, and a screenshot of the visible area. Opening the extension sends nothing. It only reads the page you are on, and only after you click Start scan. Nothing runs in the background.
