Amazon A/B Tests And Rejects Wider And Smaller Product Titles

Leak #94 from Amazon.ca   |   Jun 9, 2023 Product

Amazon has been noticed a/b testing their product titles styles with at least 3 variants. The first variation stretched the width of the product title. The second variation decreased the font size. While the third variations combined both changes together - possible checking for interaction effects. Nevertheless, as of today the experiment looks like it completed and all three variations were rejected - hinting at higher optimality for the status quo (the control shown as "A"). 

What's more, Etsy A/B tested very similar smaller product titles, which were also rejected.

Highlighted UI Changes From This Leak

  1. Var B: Wider Product Titles

    In this variation we can see a widening of the product title from a the middle column, stretched over on top of the product photo. As a consequence of this, the product photo was pushed downwards.

  2. Var C: Smaller Product Titles

    Here, the font size of the product titles was decreased.

  3. Var D: Wider And Smaller Product Titles

    Finally, in this variation both variables (title width and font size) were combined together - possibly checking for interaction effects.
