Why cross-post from TikTok to LinkedIn?
LinkedIn is embracing short-form video, and creators who repurpose educational TikToks are seeing massive engagement. The key is selecting the right TikToks—not every dance trend belongs on LinkedIn. Focus on industry insights, career tips, and behind-the-scenes business content.

How to cross-post from TikTok to LinkedIn
- 1
Select educational or professional TikToks only
LinkedIn is not the place for dance trends. Choose TikToks about industry insights, career advice, productivity tips, or behind-the-scenes business content.
- 2
Download watermark-free
A TikTok watermark on LinkedIn looks unprofessional. Always upload a clean version.
- 3
Rewrite the caption in a professional tone
Replace casual TikTok language with professional insights. LinkedIn captions can be up to 3,000 characters—use this to add context, data, or your expert perspective.
- 4
Add industry-relevant hashtags
Use 3-5 professional hashtags like #Leadership, #Marketing, or #CareerAdvice. Avoid TikTok-style trending tags.
- 5
Keep video under 10 minutes
LinkedIn supports videos up to 10 minutes. Most TikToks fit easily, but consider the context—LinkedIn audiences prefer 1-3 minute educational content.
Formatting tips for TikTok to LinkedIn
Professional tone is essential
LinkedIn audiences expect thought leadership, not casual banter. Rewrite captions with industry language and actionable insights.
LinkedIn supports longer video
LinkedIn allows up to 10 minutes vs TikTok's 3 minutes. But shorter, punchy content (30s-3min) performs best on LinkedIn too.
Use 3-5 industry hashtags
LinkedIn hashtags should be professional: #SocialMediaMarketing, #ContentStrategy, not #fyp or #viral.
Common mistakes to avoid
Posting casual/trendy TikToks on LinkedIn
Only cross-post educational, business, or career-related content. Trendy dances and memes will get negative reactions on LinkedIn.
Using casual language
Rewrite your caption for professionals. "OMG this hack is fire" becomes "Here is a strategy that increased our engagement by 40%."
Ignoring LinkedIn's text-heavy culture
LinkedIn users love reading. Add a substantial caption with your professional take, not just the video with a one-liner.
Pro Tip
Add "What do you think?" or "Has anyone else experienced this?" at the end of your LinkedIn caption. LinkedIn's algorithm heavily rewards comments, and questions are the #1 way to drive them.
