- Google is focusing on mobile page speed and user experience as part of its search rankings. A study was conducted analyzing the page speed and optimization of over 1 million pages.
- The results showed that optimization score, which measures how well a page leverages browser caching and prioritizes visible content, had a strong correlation with search rankings. However, page speed metrics like first content paint and load time did not correlate as much.
- This indicates that for mobile search rankings, page optimization is more important than raw speed numbers. Site owners should focus on optimizing aspects like response time, redirects, compression, caching, and prioritizing visible content to improve rankings.
