Your page has CSS or JavaScript files that are blocking the initial render on mobile devices. This is particularly problematic on mobile because of slower network connections and less processing power. These resources prevent the page from displaying content until they're fully loaded, creating a poor user experience.
<link rel="stylesheet" href="large-stylesheet.css">
<script src="heavy-script.js"></script>Use techniques like inlining critical CSS, deferring non-critical resources, and adding async/defer attributes to scripts.
<style>/* Critical CSS inlined */</style>
<link rel="preload" href="stylesheet.css" as="style" onload="this.onload=null;this.rel='stylesheet'">
<script src="script.js" defer></script>Optimizing render-blocking resources allows the page to display content faster, especially important on mobile devices where every millisecond counts for user experience and Core Web Vitals scores.
This issue can affect your site's search engine rankings and user experience. Addressing it promptly helps ensure optimal performance and visibility in search results.
