What does "link in bio" mean?

"Link in bio" means: go to my profile and tap the link there. It is how people on Instagram, TikTok and other apps send you somewhere else, because links inside posts and captions usually are not clickable.

The meaning of "link in bio"

Your bio is the short description at the top of your social media profile. Most apps let you add a website link there, and it is often the only clickable link on your account. So when a creator says "link in bio", they mean: tap my username, then tap the link under my bio to find the thing I just mentioned.

  • On Instagram: captions and comments do not create clickable links, so "link in bio" became the standard way to point people to a shop, article or video.
  • On TikTok: the same applies to video captions. The website link on your profile is where people go next.
  • On YouTube, X and Threads: you will see it too, usually pointing to the same page as everywhere else.

What is a link in bio page?

A link in bio page is a simple mobile web page that holds all your links in one place. Instead of swapping the single link in your bio every time you post something new, you put one link there that never changes, and update the page behind it.

A good link in bio page does more than list links. It can show your latest video or song, collect email sign-ups, share a countdown to a launch, and tell you which links people actually click. That is what we built Link in Bio for.
