How much do design, site speed, and product reviews affect e-commerce checkout behavior? Even more than you might think...

Regarding general design, some 93% of people say visuals are the most influential factor in the purchase decision, according to vouchercloud.

Moreover, shoppers assess a product within 90 seconds to determine whether to purchase it.

Site speed also plays a huge role. If a page takes three seconds to load, 57% of online consumers will abandon the site; of those visitors, 80% will never return.

Product reviews, too, influence online shoppers. Some 85% of consumers read online reviews for local businesses before making a purchase. "Of those, 79% trust the reviews as much as a personal recommendation," vouchercloud writes.
