Frequently asked questions
Why does TikTok cut my bio mid-sentence?
TikTok’s limit is short (~80 characters). A LinkedIn-length bio will truncate. Paste once here and shorten until every platform you care about is green.
Should I use the exact same bio everywhere?
Keep one core message, then adapt tone and length. LinkedIn can be more professional; TikTok needs the sharpest line first.
What belongs in a bio so people actually follow?
Who you help, what you do, and one reason to stay (proof, CTA, or niche). Keywords help discovery; fluff wastes the limit.
Do emojis count toward the limit?
Yes — and some count as more than one character depending on the platform. Watch the meters update as you type instead of guessing.
