Listing

In this experiment on a listing page, the search was expanded to show more listings (variation B). Conditionally, if there were fewer than 36 results, set basic filters such as number bedrooms and bathrooms were expanded and appended to the results. Hence if someone chose 2 bedrooms and 2 bathrooms in variation A, they would only see listing with that filter. In variation B however they would first see the filtered results, and later they would also see results with 3 or more of each.

Listing

In this listing page experiment, color sets of the same product were tested against individual products with unique colors (with additional product tiles). Essentially, the A version here contained fewer product items (with color sets), while the B version contained more results and tiles (with grouped products). Impact on total sales was measured.

(The original control and variation was inverted, but was flipped to match the fewer or more results pattern).

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

B - Jun 13, 2020 IMPLEMENTED

Amazon just completed this wonderful product page layout experiment. The experiment was visible on wider monitors where the main content column was set to either full width (control) or fixed to 1500 pixels (B variation). View Leak

Amazon A/B Tests The List Vs Grid Layout

A - Sep 5, 2020
B - Sep 5, 2020 IMPLEMENTED

A month ago I managed to detect this classic list vs grid layout experiment on two of Amazon's product listing pages. I learned that this a/b test ran at least on two random queries such as "tools for mechanics" and "sports gear". Today, the grid layout view now looks like it was implemented. 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.
