How does mobile page loading speed affect content recommendations on Google Discover?

When mobile page loading speed is too slow, it will significantly reduce the probability of content being recommended by Google Discover. Google Discover relies on user experience signals to evaluate content value, and loading speed is one of the core indicators. Page loading speed directly affects user dwell time - when loading takes more than 3 seconds, the user bounce rate will rise sharply, causing the Discover algorithm to judge that the content has low value to users. In addition, indicators such as Largest Contentful Paint (LCP) in Core Web Vitals have been explicitly incorporated into Google's evaluation system by Google, and slow loading will lower the scores of these indicators, further reducing the recommendation weight. Optimizing mobile loading speed can start with basic methods such as compressing images, enabling browser caching, and using CDN acceleration, which helps increase Discover recommendation opportunities and improve overall user experience.
