Meta Video 50% Views: Measure Mid-Video Engagement

The number of times your video ads were watched to at least 50% completion—indicates moderate viewing engagement.

Formula

Meta Video 50% Views = COUNT ( 50% Completion Views )

Type	Number
Data Source	Meta Ads
Aggregation	Sum

Example

Your fitness brand ran a 40-second workout preview across three ad sets last week. Here’s how viewers progressed through each video:

Ad Set	Impressions	50% Views	50% View Rate
Morning Routine	62,000	18,600	30%
HIIT Preview	48,000	20,160	42%
Recovery Tips	55,000	11,000	20%

The HIIT preview maintains viewer attention through the midpoint, while Recovery Tips needs a stronger narrative hook.

How It Works

Meta fires a 50% completion event when a viewer watches at least half of your video’s total duration. For a 40-second video, this means watching at least 20 seconds. This metric counts each qualifying view, including repeat views from the same person.

When to Use

Scenario	Action
Strong 25% but weak 50% views	Your middle content loses viewers—tighten the narrative
Comparing video lengths	Shorter videos often have higher 50% rates; test formats
Building warm remarketing audiences	Target 50%+ viewers for bottom-funnel conversion ads
Evaluating message delivery	50% completion means your core message likely landed

Metric	Relationship
Meta Video 25% Views	Earlier funnel stage showing initial hook effectiveness
Meta Video 75% Views	Next milestone showing strong content retention
Meta Video Completions	Viewers who watched your entire video
