What does link in bio mean?

Link in bio means the link a post mentions is on the account's profile, not in the post. Instagram does not make web addresses in captions or comments clickable, so creators put the link on their profile and send you there. Tap the account name, and the link sits under the bio text.

Why posts say link in bio

Instagram turns the links on a profile into tappable links, but not web addresses typed into a caption or a comment. So when a post mentions a new video, a product or a sign-up, the caption points you to the one place a link works: the profile. TikTok keeps its website link on the profile too, and only accounts with 1,000 followers or a verified business account can add one.

Finding it

Where to find the link in someone's bio

Tap the account's name or photo to open the profile. On Instagram, the links sit under the bio text, and anyone who views the profile can see them. An account can show up to five. On TikTok, the website link also appears under the bio, and it opens in TikTok's own browser, which may hand you over to your phone's browser.

What a link in bio page is

Many creators do not point their profile link at a single website. They point it at a link in bio page: a small mobile page that lists everything they currently share, such as a new video, a shop, a booking link or an email signup. The profile keeps one link, and the page behind it changes as often as they like.

Link in bio: frequently asked questions

Short answers on what it means, where to find it and how to add one.

What does link in bio mean?

It means the link the post talks about is on the account's profile. Tap the account name to open the profile, and the link sits under the bio text.

Why can't people put links in Instagram captions?

Instagram does not turn web addresses in captions or comments into clickable links. Links work in the Links section of a profile and in stories with a link sticker.

Where is the link in bio on Instagram?

Open the profile by tapping the account name. The links appear under the bio text, and anyone who views the profile can see them.

Where is the link in bio on TikTok?

On the profile, under the bio. TikTok only lets accounts with at least 1,000 followers or a verified business account add a website link, so smaller accounts may not have one.

What does check the link in my bio mean?

The same thing: the person wants you to open their profile and tap the link there, because the post itself cannot carry it.

Is it safe to tap a link in someone's bio?

The link opens like any other web page, so the usual care applies. Check the address before you sign in or pay for anything, and be careful with accounts you do not know.

How many links can I put in my Instagram bio?

Up to five, according to Instagram's help centre. You add them in the Instagram app under Edit profile and Links, not on a computer.

How do I add a link to my TikTok bio?

Tap Profile, then Edit profile, then Add next to Links. TikTok shows the option to accounts with at least 1,000 followers or a verified business account.

What is a link in bio tool?

A service that gives you a small mobile page with several links, which you then use as the link on your profile. PostNext, Linktree and Beacons all offer one.

Is a link in bio page free?

Often, yes. The PostNext Free plan includes one published page at postnext.io/s/yourname with every block type, click analytics and a QR code. Paid plans add more pages, your own domain and the option to remove the small Made with PostNext badge.

Does link in bio work on other platforms?

The phrase is most common on Instagram and TikTok, but the idea works anywhere a profile has a website field, such as YouTube, X, Threads and LinkedIn. One link in bio page can serve all of them.

What should I put in my link in bio?

Whatever your recent posts point to: your newest video, a product, a booking page or an email signup. If you share more than one thing, a link in bio page keeps every post's link live at once.
