Rolled out between June and September 2021, this update made mobile-friendliness, web safety, interstitials, and overall UI/UX official ranking signals.
Websites that prioritized page experience saw ranking improvements, while those that didn’t fell behind. This guide walks you through how to optimize your site to align with Google’s Page Experience metrics

💡 What Is UX & Why Does It Matter?
💡 What Is UX & Why Does It Matter?
User Experience (UX) measures how users interact with your site before, during, and after visiting.
A beautiful design alone isn’t enough — your interface must make it easy for users to achieve their goals.
Key UX Statistics:
88% of users won’t return after a poor experience.
50% of sales are lost to bad UX.
75% of credibility judgments are based on usability.
53% of mobile users leave if a page takes longer than 3 seconds to load.
A well-optimized UI can improve conversions by up to 200%.
With competitors only a click away, great UX isn’t optional — it’s essential for visibility and conversions.
