Prototypicality (Jakob's law)

People prefer sites that look and work like the ones they already know.

Where it applies

Four of the eight page areas.

How to use it

Five ways to use it, and one to avoid.

  • Put the logo top left, linking to the homepage, and the basket top right.
  • Make search prominent.
  • Keep checkout in the standard order.
  • Look like a shop in your sector at first glance.
  • Keep the first screen visually simple.
  • Avoid: centred logos, which NN/g found made getting home fail six times as often.
What the research found

Typical, simple sites are rated more attractive within 50ms. No sales studies were found.

Centred logos made reaching the homepage in one click fail six times as often.

Tuch and colleagues found sites that looked typical and visually simple were rated more attractive within 50ms, and even at 17ms. Roth and colleagues (516 people) found web users largely agree where online shop elements belong. In a 50-person NN/g study, centred logos made reaching the homepage in one click fail six times as often. No sales studies were found.
