Robert Gilbreath, VP of eCommerce Marketing and Analytics at Calendars.com, will discuss testing approaches to optimize the checkout page. The presentation will cover the history of website testing and personalization, avoiding decisions based on gut instinct alone ("HIPPO"), and taking a modern approach using technology and data-driven testing. Case studies from Calendars.com will demonstrate the impact of testing elements like time-based messaging, store locators, email consistency, button colors, page layouts, and shopping cart flows. Testing yielded increases in key metrics like conversion rates and revenue. The presentation aims to demonstrate how small changes from testing can provide meaningful results.
