Jakob's Law: Users Prefer the Familiar

Users don't judge your site in isolation — they judge it against every other site they've ever used.

The law

Jakob Nielsen's observation from 2000 still holds: users spend most of their time on other websites, so they expect yours to work the same way. Familiar patterns feel intuitive; novel patterns feel broken — even when they're objectively better.

In practice

• Put the logo top-left, navigation across the top, search top-right. Boring? Yes. Usable? Also yes.
• A shopping cart icon doesn't need reinventing. Neither does a hamburger menu.
• Save your creativity for where it differentiates you — the core value proposition — not for reinventing the scroll bar.

The nuance

Jakob's Law doesn't forbid innovation. It says: innovate where you win, conform where you don't. Novelty has a learning cost — spend that budget on the thing that makes you special, and borrow everything else from convention.

The bite

When in doubt, do what everyone else does. Familiarity isn't laziness — it's respect for the user's time.
