The old statistic was ten seconds. Pre-2020 research suggested visitors decided to stay or bounce in about that long. The number kept dropping. Current field data from Chrome UX Reports puts it somewhere between 8 and 15 seconds — and almost half of that budget is spent on the page loading, not reading.
In other words: by the time your page finishes rendering, the visitor already has one foot out the door.
That changes the design problem.
The design problem is not “make a beautiful page.” It’s “earn the next fifteen seconds.”
Second by second
Second 1–3: The page loads. If it’s still spinning, the visitor is gone. Every design decision that delays the hero section’s paint is a decision against the visitor. Heavy fonts, large images above the fold, hero videos — each one spends seconds of a budget you don’t have.
Second 4–6: The visitor’s eye scans the hero. They’re reading the biggest text first. Not your logo. Not your navigation. The H1. If your H1 is vague (“Elevating Your Brand”), the visitor hasn’t learned anything useful yet. Seconds lost.
Second 7–10: The visitor looks for the next piece of information. This is when they decide whether to scroll. If the space below the H1 is more generic marketing speak or a second slogan, they’re already committing to leave.
Second 11–15: The visitor either scrolls (engaged) or reaches for the back button (gone). The only way to earn the scroll is to give them specificity in those first ten seconds — a named audience, a concrete outcome, or a visible proof point.
The sites we build are organized around this rule. The hero’s job is not to tell a story. It’s to answer one question — “am I in the right place?” — in the first fifteen seconds. That’s baked into how we approach website design and development from the first wireframe.
Everything else can wait for the second scroll. But if you don’t earn the first scroll, there is no second one.
