What is a link in bio, and do you need one?

Most social apps give you exactly one place for a clickable link: the website field in your profile. A link in bio is a single page you put in that field, which then holds everything else you want people to find: your latest video, your shop, your newsletter, your booking page.

When someone says "link in my bio", that page is what they mean.

Why one link isn't enough

You probably have more than one thing going on. A creator might have a YouTube channel, a merch store and a podcast. A café has a menu, opening hours, a map and delivery apps. A coach has a booking calendar, a free guide and paid programmes.

Swapping the one link in your profile every time something new comes out is tiring, and the old link breaks for anyone who saved it. A link in bio page solves that: the address stays the same, and you change what's on it.

What a good link in bio page includes

Keep it short and put the most important thing first. A good page usually has:

• Who you are, in one line. A short bio under your name so visitors know they're in the right place.
• Your top two or three links. The thing you want most people to tap goes at the top.
• A way to stay in touch. An email signup or contact form, so you're not relying on one app's algorithm.
• Social icons. Small icons for your other profiles, so people can follow you where they prefer.

Depending on what you do, you might add a product with a price, a tip jar, a booking link, opening hours, a map or a playable video.

When a link in bio is the right choice

A link in bio page works best when:

1. Most of your audience finds you on social apps. They're on a phone, they want one tap, and they'll leave if a page is slow.
2. You have several destinations. If you only ever share one thing, link straight to it instead.
3. You don't need a full website yet. A link in bio page takes minutes, not weeks, and you can add a website later.

If you already have a website, a link in bio page still helps: it's a quick, phone-friendly hub for social visitors, and it can point to the most useful pages of your site.

What to look for in a link in bio tool

Not every tool is built the same. Before you pick one, check these:

• Fees on sales. Some tools take a percentage of what you sell on their cheaper plans. If you sell anything, that adds up quickly. See our fee comparison for real numbers.
• Analytics without a cookie banner. You want to know what people tap, without making every visitor click through a consent popup.
• Design choices. Your page should look like you, not like everyone else using the same template.
• Your data. Can you download your links, subscribers and stats if you ever leave?
• Your own domain. A custom address like links.yourname.com looks more trustworthy and is easier to remember.

Biotrail does all of these on the free plan: 54 link layouts, analytics with no cookie banner, a custom domain and 0% fees on sales. If you're coming from another tool, you can compare Biotrail with Linktree.

How to set one up in five minutes

1. Claim your name. Pick the same handle you use on social media so people recognise it.
2. Add a photo and a one-line bio. Use the photo people already know you by.
3. Add your top three links. Lead with whatever matters most this month.
4. Pick a look. Choose a layout and colours that match your brand.
5. Put the link in your profiles. Paste it into the website field on every platform you use.

Then check your analytics after a week. Move the link people tap most to the top, and remove anything nobody uses.

The short version

A link in bio is one page, at one address, that points to everything you do. It's quick to set up, easy to update, and saves you from swapping links every week. Keep it short, lead with what matters, and choose a tool that doesn't take a cut of what you earn.
