What is Viewability Rate

Viewability Rate is a key performance indicator (KPI) that measures the percentage of served ad impressions that were actually viewable by users. It helps evaluate the effectiveness of ad placements by determining whether ads are positioned in areas where they are likely to be seen. Simply serving an ad doesn’t guarantee it will be visible, as factors like ad placement, user scrolling behavior, ad blockers, and page load speed can prevent visibility. A high viewability rate indicates optimized campaign settings and strong ad placement, leading to better engagement and a greater potential for conversions. Monitoring this KPI is essential for improving ad performance and ensuring advertising budgets are effectively utilized.
