No isolated Facebook metric determines whether content worked well. This guide covers what each platform-specific metric means (reach, plays, retention, shares, reactions) and how to combine them to decide what to improve.

No isolated metric determines whether a piece of Facebook content worked well. Reach, plays, retention, and engagement tell different stories — they read better combined than separately.
The general meaning of video metrics (shared with other platforms) is covered in which metrics to analyze to improve your videos; here we detail how they apply specifically to Facebook.
Retention (what proportion of the video is watched at each moment) works the same as on any short video: a sharp drop in the first few seconds usually signals a hook that didn't deliver on its promise. Accumulated total watch time helps understand a piece of content's aggregate impact beyond just one-off views.
| If you observe... | It usually signals |
|---|---|
| High reach, low initial retention | The hook didn't deliver on its promise or didn't generate enough interest |
| Good retention, few shares | The content entertains but isn't perceived as memorable enough to share |
| Many reactions, few new followers | The content is liked one-off but doesn't communicate a clear reason to follow the profile or Page |
| Many comments with repeated questions | There's a clear opportunity for follow-up content on that same topic |
