Content Best Practices

Fundamental Principles

The 3-Second Rule

You have about 3 seconds to capture attention. Your main message should be understood at a glance.

Less is More

Don't overload the screen with information. One clear message per screen is more effective than multiple messages competing for attention.

Clear Visual Hierarchy

The most important element should be the most visible. Use size, color, and position to guide the viewer's eye.
