Looking ahead to the 2024 holiday season, U.S. retail e-commerce sales are projected to reach $271.58 billion-a 9.5% increase from 2023-with mobile commerce expected to contribute nearly 28% to this growth. With more consumers shopping on their phones, mobile optimization will be critical for retailers aiming to capitalize on this trend. Nearly 27% of U.S. and UK adults plan to start their holiday shopping in October, giving brands an extended window to capture early sales before the peak period.
