A link in bio, also called a bio link, is the one clickable link on a social media profile. Creators write “link in bio” in captions because Instagram and TikTok don't make caption links tappable, so the phrase sends viewers to the profile link, which usually opens a page listing everything the creator wants them to see.

## What does “link in bio” mean?

It means the link is on the poster's profile rather than in the post. Apps such as Instagram and TikTok don't make links in captions tappable, so creators write “link in bio” to send viewers to the address in their profile, which usually opens a page listing everything they currently want you to see.

## Why can't I just put links in my captions?

On Instagram and TikTok a web address in a caption shows up as plain text that can't be tapped, and few viewers will copy one by hand. The website field on your profile is the dependable clickable spot, which is why everything gets routed through it.

## Do I need a link-in-bio page, or can I link straight to my website?

If everything you share lives on one page of your site, link straight to it. A link-in-bio page earns its place when your posts point at several things at once, such as a release, a shop, a booking page and a newsletter, and those change more often than you would redesign a website.

## How many links should a link in bio have?

As few as cover what your posts are currently pointing to. There is no magic number: each extra link costs attention that the one you most want tapped could have had. Check which links get clicked, and retire the ones nobody uses.

## How do I know if my link in bio is working?

Compare views with clicks. Views tell you how many people crossed over from your profile; clicks per link and the click-through rate tell you which destinations they wanted. When a platform sends visitors who don't click anything, the page isn't matching what your posts there promised.

## Can a link-in-bio page show up in search results?

Yes, for your own name, if its title and description say who you are and your profiles link to it. Serving it on your own domain keeps whatever it earns under your brand. It won't rank for topics it doesn't discuss, because a list of links has little to say. BioFlow keeps a page out of search until its published version has a few real blocks, and a new workspace that hasn't paid for a plan or verified a custom domain waits about a week first.

## Can I make a link-in-bio page for free?

Yes. BioFlow's Free plan costs US$0 with no card: a full public page, every basic block, all 10 integrations and 25 agent messages per 30 days. Custom domains are on Creator and Pro.
