What is Link in Bio?
Link in bio is the clickable URL in a social media profile, and by extension the landing page it points to. Because Instagram and TikTok don't make caption links clickable for most accounts, the bio link is where posts send people to act.

Why link in bio matters
On Instagram and TikTok, links in captions aren't clickable for most accounts, so the profile link is the main path from content to your website, shop or booking page. Every “link in bio” call to action sends people there, which makes it one of the highest-intent clicks on your account. A single URL can only point to one place, which is why many brands use a link-in-bio page that lists several destinations.
Profile links by platform
| Platform | Profile links |
|---|---|
| Up to 5 links in the bio; Story link stickers and links sent by DM also work | |
| TikTok | A website link for business accounts, and for personal accounts that meet TikTok's requirements |
| X | A website field, plus links in the bio text |
| Website links in contact info; pages and Premium profiles can add a custom button | |
| YouTube | Several links on the channel page, and clickable links in video descriptions |
| Website and links on the Page, and clickable links in posts |
What to put on a link-in-bio page
- Your most important action first: shop, book or sign up.
- The current campaign or latest content, updated as posts go out.
- Contact options and a few key pages.
- Roughly six to eight buttons at most; long lists spread clicks thin.
How to measure it
Track taps on the profile link (Instagram insights report them), clicks on each button of your landing page, and conversions on your site from UTM-tagged links.
A worked example
A photographer's bio link points to her homepage. She replaces it with a link-in-bio page with three buttons: “Book a session”, “Wedding portfolio” and “This month's mini-session offer”. Button clicks show that most visitors want the offer, so she keeps it at the top and changes the offer monthly.
Common mistakes
- Pointing to a generic homepage that isn't built for visitors arriving from a phone.
- Leaving an expired offer at the top after a campaign ends.
- Too many buttons with vague labels.
- No tracking, so you can't tell which posts drive clicks.
Link in Bio FAQ
What does “link in bio” mean?
It tells viewers that the link a post mentions is in the account's profile, because platforms like Instagram and TikTok don't make links in captions clickable for most accounts.
How many links can I have in my Instagram bio?
Instagram allows up to five links in the bio. A link-in-bio page is still useful when you want more destinations, your own branding or click tracking.
Is a link-in-bio page bad for SEO?
No. It's a small landing page for social visitors, not a replacement for your website. Link from it to your own site so visitors, and search engines, can reach your main pages.
