Mobile-First Approach Drives Gilt.com's Digital Success

1. Design for each device. For example, take advantage of the large retina displays the iPad offers as well as the browsing nature of its users, while make site search a more prominent feature on smartphones, which offer less screen real estate to display products.

2. Optimize for weekends and downtime. Mobile usage peaks on weekends and holidays, John said, so offer mobile-exclusive content and sales during this time. For example, iPad usage tends to peak in the evening when consumers are relaxing at home, so consider running a flash-sale on your iPad app during this time frame.
