Users transfer expectations from other apps, familiar layouts reduce friction.
The Principle: Users spend most of their time on other websites. They prefer your site to work the same way as all the others they already know.
- Follow Conventions: Use standard icons (like a magnifying glass for search) and common layouts.
- Don't Reinvent the Wheel: Prioritize clarity and predictability over unique but confusing innovations.
- Transferable Experience: Leverage existing mental models so users can focus on their tasks rather than learning how to use your interface.
