Which video format produces longer view duration?

Meta typically pulls higher absolute view counts at lower per-view depth. LinkedIn pulls fewer views with longer per-view duration on B2B content.

Should I caption my LinkedIn video?

Yes — sound-off impressions are 80% of LinkedIn video traffic. Captions are mandatory for full comprehension.

How long should B2B video creative be?

30-60 seconds is the sweet spot for both LinkedIn and Meta on B2B campaigns. Past 90 seconds completion rates collapse.

LinkedIn Video vs Meta Video Character Limits

LinkedIn Video Ads and Meta Video Feed Ads share the same architectural pattern — autoplay video inside a vertical feed — but with different intro-text ceilings and reading expectations.

LinkedIn Video allows 700 characters of intro text (Meta video uses Feed primary at 500 chars). Both clip at similar visible windows: LinkedIn at ~150 visible, Meta at 125. The 100-character LinkedIn headroom past the visible clamp matters because LinkedIn's audience taps "see more" at 2-3x Meta's rate on professional content.

A second difference: LinkedIn's video autoplay is muted by default for sponsored content, and the platform reports that 80% of video impressions happen sound-off. Meta also defaults muted but with sound-on behavior more common when users actively engage. Both require closed captions for accessibility and comprehension parity.
