Smartphones are increasingly popular and driving changes in consumer behavior and online activity. This presents new revenue opportunities for agencies to develop mobile optimized strategies, content, and experiences for their clients.

To succeed, agencies must develop mobile-first strategies and prioritize user experience over monetization by fully integrating mobile into their work.
