The need for mobile speed.
Today, we’re excited to share insights from a new study on how mobile speed can impact user engagement and publisher revenue. As people’s expectations for mobile experiences have grown, simply loading on a mobile device is no longer enough. Mobile sites must be fast and relevant.
Unfortunately, based on our analysis of 10,000+ mobile web domains, we found that most mobile sites don’t meet this bar: the average load time for mobile sites is 19 seconds over 3G connections.1 That’s about as long as it takes to sing the entire alphabet song!2
Slow loading sites frustrate users and negatively impact publishers. While there are several factors that impact revenue, our model projects that publishers whose mobile sites load in 5 seconds earn up to 2x more mobile ad revenue than those whose sites load in 19 seconds.3
The study also observed 25% higher ad viewability4 and 70% longer average sessions5 for sites that load in 5 seconds vs 19 seconds.
That’s why we’ve been so focused on mobile-first solutions to help publishers succeed — from our participation in the nearly year old AMP project, to our launch of a scalable native advertising solution, to our investment in products that help publishers increase revenue while minimizing latency. Never before has mobile speed been more important.
3...2...1… goneSlow page load times are a big blocker:
- 53% of visits are likely to be abandoned if pages take longer than 3 seconds to load6
- One out of two people expect a page to load in less than 2 seconds7
- 46% of people say that waiting for pages to load is what they dislike the most when browsing the web on mobile devices8
- The average size of the content on mobile sites is 1.49 MB, which takes 7 seconds to load over 3G connections9
- Mobile pages make an average of 214 server requests, and nearly half of all server requests are ad-related10
Getting up to speedThere are many tools out there to help diagnose the problem and fix it. We recommend a 3-step process to speed up mobile sites:
- Assess the current performance of the site using tools like PageSpeed Insights, Mobile-Friendly Test, and Web Page Test.
- Monitor performance after making changes and run A/B tests to regularly audit the setup of your site, flagging and removing anything that adds latency.
