You can now analyze and optimize server-side ad performance across your streaming content with the new Ad insertion analytics tab. This feature gives you clear visibility into how SSAI contributes to monetization, delivery quality, and viewer experience.

High ad demand doesn’t always translate into strong revenue. Delivery failures, low fill, or poor render rates can limit performance. Ad insertion analytics help you understand where ads succeed, where they fall short, and why.

New Feature

The Ad insertion tab provides detailed insights into SSAI performance, helping you refine your ad strategy using key delivery and demand metrics:

• Measure ad delivery with impressions, render rate, and ad breaks
• Evaluate demand quality using fill rate and ads per session
• Discover how many video plays generate monetizable ad opportunities
• Identify performance trends across countries, devices, media, and ad configurations
• Detect revenue gaps caused by low fill, delivery failures, or weak demand

See our documentation to learn more. 

The Keep watching player has been moved to the Dynamic Strategy Rules Advertising settings and now supports an additional trigger based on ad playback during a media item.

New Feature

When Dynamic Ads use a 1:1 Maximized ad rule, the Keep Watching button and countdown appear once the required ad-to-content duration ratio is reached during playback:

• If the viewer clicks Keep Watching, playback of the current video continues.
• If the viewer does not click the button before the countdown ends, the player advances to the next video, starting a new session and resetting the ad time.

We’re excited to introduce the Ad Serving tab, bringing clearer visibility into how advertising performance drives your revenue.

High player starts don’t always lead to strong monetization, since ad delivery varies by geography, platform, demand source, and auction dynamics. The Ad Serving tab helps you understand where revenue is earned and what’s influencing it.

New Feature

The Ad Serving tab helps you monitor and analyze monetization performance with insights across revenue, ad impressions, demand sources, and delivery quality:

• See which geographies, platforms, and domains generate the most revenue
• Compare player starts, ad impressions, and win rates
• Identify high-performing and underperforming demand sources and line items
• Spot revenue gaps caused by low win rate, low fill, or low-value traffic
