Cross-posting

Cross-posting is publishing the same piece of content on several platforms. It is the most common way creators cover more ground without making more work.

Does it hurt your reach?

The version people worry about is watermarks. A video exported with another platform's logo on it is the thing most likely to be treated as recycled, and removing it solves most of the concern.

Posting the same idea in each platform's native format is normal and does not carry a penalty. Uploading a visibly borrowed file might.

Doing it well

• Export clean, without watermarks.
• Rewrite the caption per platform. Length and tone differ more than the video does.
• Do not post everywhere at the same minute. Different audiences are awake at different times.
• Skip platforms the format does not suit rather than forcing it.

When not to

If a platform is genuinely a different audience for you, cross-posting everything trains them to expect content that was not made for them. Some of your output should be native to wherever it does best.
