What is a link in bio? The complete guide

A link in bio is the single URL you can add to your profile (your “bio”) on social platforms like Instagram, TikTok, Twitter/X, LinkedIn, and YouTube. When someone taps or clicks it, they leave the app and open that link — usually a link in bio page that lists multiple links, such as your website, store, latest video, or newsletter signup.

The phrase “link in bio” is so common that people use it even when the link isn’t literally in the bio (e.g. in a story or post). The idea is always the same: one main link that sends your audience to a hub where they can choose where to go next.

Most social apps limit you to one clickable link in your profile. The reasons are both product and business: they want you to stay in the app, and they don’t want every post to send traffic elsewhere. So you get a single “website” or “link” field — and that’s where a link-in-bio page comes in.

By sending people to one URL that then lists many links (your blog, shop, contact form, etc.), you get around the one-link limit without breaking any rules. Your bio link becomes the gateway to everything you care about.

A link-in-bio page is a small, focused site built around that one URL. It’s designed to be opened on mobile (where most people tap “link in bio”) and to load fast. Typically it includes:

• Buttons or cards that link to your website, store, latest post, or signup page
• Optional profile photo and short bio so it feels like your page
• Sometimes multiple pages (e.g. About, Contact) or a blog so you can share more than just links

The best link in bio tools let you edit your links and layout anytime without coding. You change the destination of a button, add a new link, or switch the order — and your one bio URL stays the same.

Almost anyone with a public profile can benefit from a link in bio. The most common use cases are:

• Creators and influencers — to drive traffic to YouTube, Patreon, merch, or a newsletter
• Freelancers and consultants — to share a portfolio, booking page, or contact form
• Small businesses and brands — to link to a shop, menu, or booking system
• Musicians and artists — to promote new releases, tickets, or a store
• Bloggers and writers — to send readers to articles, books, or a subscription

If your audience is on Instagram, TikTok, or Twitter, having a clear, up-to-date link in bio is one of the easiest ways to convert followers into visitors, subscribers, or customers.

What you put on your link in bio page depends on your goal. Here are the most common elements:

• Your main offer — e.g. “Watch my latest video,” “Shop,” “Subscribe to my newsletter.” Put this near the top.
• Website or portfolio — so people can learn more about you or your work.
• Contact — a “Contact” or “Work with me” link or a contact form so brands and clients can reach you.
• Social links — other profiles (YouTube, TikTok, etc.) if you want to cross-promote.
• One or two seasonal links — a new product, an event, or a limited-time offer. Update these when they change.

Keep the list short and clear. Five to ten links is usually enough. Too many options can make people leave without clicking. If you need more (e.g. a blog or multiple pages), use a link in bio tool that supports multiple pages and blog so your main page stays focused.

Making a link in bio is simple: choose a link in bio tool, create your page, then paste the URL into your social profile.

1. Pick a link in bio service. Look for one that is mobile-friendly, lets you add and reorder links easily, and fits your budget. Some offer a free plan; others add features like custom domains, analytics, or multiple pages for paid plans.
2. Sign up and create your page. Add your profile photo and a short headline or bio. Then add blocks or buttons for each link (website, shop, newsletter, etc.).
3. Get your URL. You’ll get a link like yourname.tool.com or, with some tools, you can connect your own domain (e.g. link.yourname.com).
4. Put the link in your bio. In Instagram, TikTok, Twitter, etc., open your profile settings, find the “Website” or “Link” field, and paste your link in bio URL. Save.

After that, update your links when you have something new — a new video, product, or post. Your bio URL stays the same; only the page content changes.

A few simple habits will make your link in bio more effective:

• Put your top goal first. The first link gets the most clicks. Use it for your main CTA (e.g. “Subscribe” or “Shop now”).
• Use clear labels. “Newsletter,” “Contact,” “Latest video” is better than vague text. People scan quickly; make it obvious where each link goes.
• Keep it mobile-first. Most people tap “link in bio” on their phone. Your page should load fast and be easy to tap and scroll.
• Update regularly. Change “Latest post” or “New drop” when the offer changes. Stale links feel abandoned.
• Consider more than one page. If you need a blog, contact form, or an About page, use a link in bio tool that supports multiple pages and forms so you don’t cram everything into one list.

A link in bio is the one URL in your social profile. Because platforms usually allow only one link, that URL often goes to a link-in-bio page — a simple, mobile-friendly page that lists your most important links. It’s used by creators, freelancers, and brands to send followers to their website, shop, newsletter, or latest content. To make one, choose a link in bio tool, build your page with clear buttons and labels, copy your URL, and paste it into your Instagram, TikTok, or other profile. Keep it updated and put your main goal first for the best results.
