Test #218 on Yummly.com by Kimberly Cheung Jan 14, 2019 Desktop Mobile Home & Landing

Kimberly Cheung Tested Pattern #94: Visible Search In Test #218 On Yummly.com

Hypothesis: Anonymous users can't use global search while on the home promo page. We believe that if we show a global search bar to anonymous users, it presents a higher converting funnel (guided search) and will increase our sign-up rates significantly.

Control (A): Logged out users don't see global search bar.

Variant (B): Logged out users see global search bar. After searching for a keyword, the signup funnel starts with a more personalized reason to continue the signup process.
