How It Works

This metric aggregates video view data from all connected advertising platforms (Meta, Google, TikTok) to show what percentage of viewers watch at least 25% of your videos. A high 25% completion rate indicates that your video openings effectively capture viewer attention in the critical first moments.

When to Use
