How to Write a Social Media Bio That Fits Every Platform
The same three facts have to fit 80 characters on TikTok and 220 on a LinkedIn headline. Write the short one first and everything else is that plus room.
Field notes
Playbooks, teardowns and the occasional argument — everything we have learned helping creators grow across every major platform.

The same three facts have to fit 80 characters on TikTok and 220 on a LinkedIn headline. Write the short one first and everything else is that plus room.

Grouping a keyword list so each group becomes one page. The proper way needs ranking data; the approximation you can do in a browser is good enough to plan from.

Everybody can name four themes. The plan fails at the point where three posts of the same one go out in a row because that is the order the ideas arrived in.

The translation is the easy part. What catches people out is that the caption no longer fits, the hook is now below the fold, and the hashtag reaches a different set of people entirely.

A video script is four decisions, not a document: what the first line promises, how long the middle is allowed to be, what you actually say, and what has to be on screen while you say it.

No platform publishes an emoji limit, so any number quoted at you is invented. Three things about emoji are measurable, and they are what should decide the count.

Almost every disclosure that draws a regulator's attention has perfectly good wording. What it does not have is placement. Here is what to say, and where it has to sit.

Length is rarely what stops a crosspost. It is the tenth image, the eleventh hashtag, and a link that is dead text on two networks — and none of them raise an error.

The cap and the useful number are different things, and the gap is large. Instagram allows thirty and recommends three to five. Here is every platform's cap and its sensible count.

Most hashtag mistakes cost you one tag. Three of them cost you every tag on the post, and none of the three announce themselves.

Paragraph breaks vanish, hashtags stop matching, emoji arrive as boxes. Four things happen to a caption between your notes app and the feed, and all four are fixable.

Four income streams, and Twitch publishes the arithmetic for three of them. Subscriptions, bits, ads and tips — with the split applied, which is the part people forget.
