How to Post a Carousel on LinkedIn (Step-by-Step Upload Guide)

Q: Can I schedule carousels directly in LinkedIn?

Personal profiles cannot schedule documents natively. Company pages offer limited scheduling, but Postiv.ai handles multi-profile scheduling with approvals and analytics.

Q: How long should my caption be?

Stay under 1,500 characters. Lead with the hook and CTA, then use line breaks for readability.

Q: What hashtags should I use?

Select three to five hashtags aligned to your topic and target audience. Focus on tags with roughly 20k–200k followers to balance relevance and reach.

Q: Should I add the link in comments or slides?

Use both. Add clickable links on your final slide and post the primary link in the comments, pinning it for visibility.

Q: How do I track performance after posting?

Use Postiv.ai analytics or LinkedIn’s document insights to watch impressions, clicks, viewer demographics, and saves. Compare against previous carousels to find top performers.

You’ve created the perfect carousel—now publish it correctly so LinkedIn’s algorithm gives it full reach. This walkthrough covers desktop, mobile, scheduling, and promotion tips.

Tag collaborators. Mention team members or partners to increase reach.
Choose audience. Default to Public unless it’s for a private community.
