Why your LinkedIn posts don't just 'work' on TikTok

! Professional tone on LinkedIn clashes with TikTok's casual, entertainment-first audience

+ ! LinkedIn's algorithm now pushes video similarly to TikTok, but the content expectations remain different

+ ! No native way to crosspost LinkedIn posts directly to TikTok

+ ! LinkedIn carousel posts and articles don't translate directly to TikTok's video format

= too much manual work

↓ There's an easier way

What You Need to Know

01

How creators turn LinkedIn posts into TikToks

The workflow creators actually use: take the core insight from a LinkedIn post, strip out the professional framing, and rebuild it as a talking-head video.

The hook becomes the first line you say on camera, not a text opener.

Bullet points become a verbal list.

LinkedIn articles become a series of short TikToks, one idea per clip.

The manual steps — recording, editing, adding captions, choosing a trending sound, writing a TikTok-native caption under 150 characters — easily eat 30-60 minutes per repurposed post.

Many creators use OpusClip or similar tools to clip LinkedIn video content, but text posts still require a full rebuild.

02

Make your TikToks feel native, not recycled

TikTok's algorithm rewards watch time and shares, not polished production.

Drop the suit-and-tie framing.

Speak directly to camera with energy.

Use trending audio where it fits — TikTok's Discover page shows what's gaining traction.

Your caption should be short and punchy: one line that teases the video, not a summary of it.

Hashtags like #LearnOnTikTok and niche professional tags (#MarketingTips, #CareerAdvice) help without looking try-hard.

Vertical 9:16 video is non-negotiable.

Anything letterboxed or square looks like a repurpose job.

03
