“Link in bio” means the single URL you put in your Instagram, TikTok, X, YouTube, or Substack profile. Social apps often allow only one clickable link, so that URL becomes the door to everything else.
That door should open a short page: your name, a line about you, and a list of links — portfolio, newsletter, shop, booking, socials. It is not a blog and not an ad wall.
1kb.bio gives you that page without the clutter. One clean bio page at 1kb.bio/yourname. Share it anywhere people ask for “the link in my bio.”
See a sample designer link in bio page — with a profile photo and the same simple layout you get on 1kb.bio.
