Photos are the most heavily promoted compared to any other

“According to Kleiner Perkins, an average user spends over three hours
per day consuming digital media on mobile – a growth of nearly
4x over just the past five years. Mobile ads present a huge opportunity
for marketers, they just need to start thinking about using mobile-friendly
content formats. The key with mobile content is to focus on understanding
the nature of mobile, then use those learnings to test and refine your
content until you find what works best for your brand and audience.”
