What it does
The Retention Rate KPI measures how the audience engagement diminishes over the course of a video, showing where and when viewers tend to stop watching. This metric visualizes the effectiveness of the video's elements—such as brand mentions, key messages, promotions, or calls-to-action—based on their placement and timing.
Why it matters
Viewership naturally declines as a video progresses, especially on social media platforms where attention spans are short. The graph below represents the length of viewers’ attention paid to social reel advertising compared to both social feed and pre-roll advertising.

And here is the same data for just social reels (TikTok, Instagram, YT Shorts)
Less than half of the intended audience watches the first five seconds of a social reel ad – which can be problematic for advertisers who fail to quickly convey what the ad is about. Consequently, just like with other forms of online advertising, immediate attention-grabbing and rapid exposure of both brand and message remain critical.
Understanding the retention rate helps identify the points in your video where engagement drops, allowing you to optimize content delivery for maximum impact. By ensuring key information is communicated before significant drop-offs, you can enhance message retention, brand recall, and overall campaign performance, even when view-through rates are low.
How it works
This KPI tracks the percentage of viewers remaining at each second of the video and visualizes it as a curve. Steep declines indicate segments that fail to retain interest, while a gradual slope suggests better viewer engagement. Annotations along the curve pinpoint when a significant percentage of viewers leave, helping to identify the effectiveness of content placement. The retention/drop-off data can be adapted to our customers' data if available.
How to achieve great results
-
Place Key Information Early: Include critical details such as brand, product, and message within the first few seconds. This ensures viewers are exposed to the essentials even if they don't watch the full video.
-
Engage in the First Few Seconds: Use dynamic visuals, hooks, or questions to grab attention right from the beginning. This can delay the initial drop-off and increase overall view-through rates.
-
Create Multiple Peaks of Interest: Introduce new, engaging content at regular intervals to keep the audience's attention and minimize drop-off rates throughout the video.
-
Monitor and Iterate: Use the Dropoff Curve insights to identify weak spots and refine future content strategy. Experiment with different placements of CTAs, brand elements, and storytelling techniques to achieve a smoother curve and prolonged engagement.
