LinkedIn Ad Best Practices (2026)
B2B Golden Duration
15-30 seconds is the ideal video length on LinkedIn. Professional audiences are more willing to watch short, value-packed content.
Professional + Authentic
LinkedIn users expect professional content, but real people on camera build more trust than pure animation or text overlays.
Weekday Publishing
Tuesday through Thursday mornings deliver the best performance. LinkedIn engagement drops significantly on weekends.
Thought Leadership
Content that educates or shares industry insights outperforms direct product promotion. Lead with value, follow with CTA.
