+## Feedback by page
+
+Use the **Feedback by page** view to see aggregated thumbs feedback across all your documentation pages. This view shows which pages have the most positive or negative sentiment based on thumbs up and thumbs down votes.
+
+To access this view, click **Feedback by page** at the top of the feedback tab.
+
+The view displays two lists:
+
+- **Liked by viewers**: Pages with more thumbs up than thumbs down votes, sorted by the difference between positive and negative feedback.
+- **Needs improvement**: Pages with more thumbs down than thumbs up votes, sorted by the magnitude of negative sentiment.
+
+Each item shows the page path, the number of thumbs up and thumbs down votes, and a visual indicator of the feedback balance. Use this view to quickly identify your best-performing content and pages that may need attention.
