## Definition

ThruPlay is Meta's standard video-view event, counted when a viewer watches a video to 15 seconds or — for videos shorter than 15 seconds — all the way to completion. It exists as both a reported metric (how many ThruPlays an ad earned) and an optimization/billing event (you can bid for ThruPlays on certain awareness and video-view objectives). ThruPlay replaced Meta's retired 10-second video view as the platform's headline attention threshold. The share of plays that become ThruPlays is the ThruPlay Rate, and spend divided by ThruPlays is Cost Per ThruPlay. It is a Meta-specific term — TikTok, YouTube, and CTV each count a 'view' at a different threshold.

## Formula

**Formula:** `ThruPlay = 1 view counted at 15s (or completion, if video < 15s)`

A single video view credited once a viewer reaches 15 seconds — or finishes a video shorter than 15 seconds. Meta-specific, and also biddable as an optimization event.

## Calculation

**Formula:** `ThruPlays = plays reaching 15s (or completed, if the video is under 15s)`

**Explanation:** A ThruPlay is counted per qualifying play — 15 seconds of watch time, or full completion for videos shorter than 15 seconds. It is a count (and an optimization event), not a rate: divide ThruPlays by video plays for the ThruPlay Rate, or divide spend by ThruPlays for Cost Per ThruPlay.

### Components

- **Qualifying Video Views**: Plays that reached 15 seconds, or completed for videos under 15 seconds

## Examples

- A 12-second ad earns a ThruPlay every time a viewer watches it to the end
- A 45-second ad earns a ThruPlay only from viewers who reach the 15-second mark
- 10,000 video plays and 2,000 ThruPlays means a 20% ThruPlay Rate

## FAQs

### What is a ThruPlay on Meta?

A ThruPlay is Meta's video-view event, counted when someone watches your video to at least 15 seconds — or all the way through if the video is under 15 seconds. It is both a reported metric and an optimization/billing event you can bid for on awareness and video-view objectives.

### What's the difference between ThruPlay and ThruPlay Rate?

ThruPlay is a count of qualifying video views; ThruPlay Rate is that count divided by video plays, expressed as a percentage. An ad with 10,000 video plays and 2,000 ThruPlays earned 2,000 ThruPlays and a 20% ThruPlay Rate. Use the count for volume and cost (Cost Per ThruPlay), and the rate for creative-quality comparisons.

### How is a ThruPlay counted?

For videos 15 seconds or longer, a ThruPlay is counted when a viewer reaches 15 seconds of watch time. For videos shorter than 15 seconds, it is counted on full completion. The 15-second threshold is fixed regardless of total video length, which is why short videos earn ThruPlays far more easily than long ones.

### Is ThruPlay the same as a video view on TikTok or YouTube?

No. ThruPlay is Meta-specific. TikTok counts a video view at 2 seconds (with a separate 6-second metric), and YouTube TrueView counts a view at 30 seconds or completion. Because the qualifying thresholds differ, ThruPlay counts and rates are not directly comparable across platforms.
