User experience improvements with page speed in mobile search

For the slowest one-third of traffic,  user-centric performance metrics improve by 15% to 20% in 2018. As a comparison.

When a page is slow to load, users are more likely to abandon the navigation.

Speed improvements: 20% reduction in abandonment rate for navigations initiated from Search, a metric that site owners can now also measure via the Network Error Logging API available in Chrome.

In 2018, developers ran over a billion PageSpeed Insights audits to identify performance optimization opportunities for over 200 million unique urls.
