In this homepage experiment with a 4-slide carousel, the slides changed every 3.5 seconds and users could also choose another slide manually. In the variations, instead of the 4 slides in the carousel, static images were used to take up the same amount of space.

In this experiment, a single image carousel gallery was replaced with a grid gallery. In addition the variation also used: taller swatches; a wider size box, added fit (slim, relaxed, straight, wide) options; and used a wider Add to Cart CTA (full width of the column). Impact on sales was measured.

Booking's Homepage Carousel Experiment Fails As Predicted

A - Sep 25, 2019 IMPLEMENTED
B - Sep 25, 2019

I was glad to detect this carousel experiment that Booking recently ran on their homepage because we've already seen similar experiments fail in the past. Instead of showing 5 location tiles, they tested a version that only showed 3 tiles at a time with an ability to slide for more - a carousel. It wasn't the automatic slider type that would unleash the wrath of Karl Gilis, but it was a user-invoked slider nevertheless. View Leak

+0.5 Evidence

For each pattern, we measure three key data points derived from related tests:

REPEATABILITY - this is a measure of how often a given pattern has generated a positive or negative effect. The higher this number, the more likely the pattern will continue to repeat.

SHALLOW MEDIAN - this is a median effect measured with low intent actions such as initiating the first step of a lengthier process

DEEP MEDIAN - this is derived from the highest intent metrics that we have for a given test such as fully completed signups or sales.
