Anyone who’s ever abandoned a mobile site for being too slow is familiar with the negative impact of a sluggish user experience. And more than ever, as consumers look to fill their needs on mobile during the current crisis, a fast experience is critical. In fact, a new study1 provides a much clearer view of the positive effect mobile page speed can have on performance metrics that matter to marketers, including conversion rates, average order values, and even page views.
The research, commissioned by Google and conducted by 55 and Deloitte, looked at 37 leading European and American brand sites across four verticals: retail, luxury, travel, and lead generation (for example, insurance or car dealership sites). Mobile load times were monitored hour by hour for 30 days at the end of last year, with the results consolidated in real time against a range of typical mobile purchase journey metrics.
3 mobile page speed opportunities
The study showed that there are significant benefits for brands in speeding up their mobile sites.
1. Faster sites mean more customers will reach checkout
Improving site speed increases progression rates on almost every step of the mobile purchase journey — from the homepage to the checkout — for the majority of brands.

2. Faster sites encourage people to stay longer and purchase more
Decreasing mobile site load times by just one tenth of a second resulted in major performance gains. Specifically, conversion rates went up by 8.4% for retail and 10.1% for travel.
In retail alone, the average order value grew by 9.2%, while luxury sites saw an 8% rise in page views per session.
3. Faster sites have lower bounce rates
One in five retail and luxury sites studied saw their homepage bounce rates improve by 0.6% and 0.2% respectively. The results were even more profound for the lead generation brands studied, where a mobile speed improvement of just 0.1 second for an informational page decreased bounce rate by 8.3% for 1 in 2 lead generation sites.
Build a mobile-first culture
To see the benefits from site speed improvement, businesses need a mobile-oriented culture. Here are some tips to help you get there:
- Start by understanding the impact of speed on your bottom line using your own data, or using the report data as a benchmark.
- If the impact is significant, encourage your senior leadership team to make mobile speed a company priority, and to allocate the necessary resources.
- Establish a strategy to improve site speed; including a speed budget and shared mobile speed KPIs that both your commercial and technical leadership teams can agree and focus on.
- Track your site speed and link it to your analytics data to see the impact of speed improvements.
