Quick answer: Open Instagram, tap Edit profile, then use the Links (or Website) field to paste a URL and save. Instagram allows only one bio link, so to share many links at once, point that one field at a free link-in-bio page like ishort.pro/you.
What is a link in bio?
A "link in bio" is the clickable URL you can add to your Instagram profile, shown just under your bio text. It is the one place Instagram lets you send followers somewhere off the app - a website, a shop, your newest video, or a page that holds several links at once. Instagram does not make links clickable in captions or comments for most accounts, so the bio link is your reliable exit door.
Adding one takes about a minute. Below is the step-by-step for a single link, then how to fit all your links behind that one slot with a free link-in-bio page.
How to add a link to your Instagram bio (single link)
Use the Instagram mobile app - this is the most reliable way to edit your profile links.
- Open Instagram and tap your profile picture in the bottom-right to go to your profile.
- Tap Edit profile.
- Tap Links (on some accounts this is labeled Website).
- Tap Add external link, then paste your URL and, optionally, a short link title.
- Tap Done or Save. Your link now appears under your bio, ready to tap.
That is it - visitors can now tap the link on your profile. But you will quickly hit a wall: you only get this one slot.
The one-link limit (and how to get around it)
Instagram gives you a single website field. If you have a YouTube channel, a shop, a newsletter, and a latest reel to promote, you cannot list them all - you would have to keep swapping the one link and hope followers catch it at the right moment. Typing extra URLs into your captions does not help either: for most accounts, caption and comment links are not clickable, so people would have to copy and paste them by hand. (We cover that fully in Instagram clickable caption links.)
The fix is a link-in-bio page: a single URL that opens a simple page listing all of your links as tappable buttons. You put that one URL in your Instagram bio, and followers choose where to go. This is exactly what tools like Linktree do - and what IShort does for free. If you are weighing options, see our free Linktree alternative breakdown.

Here is the full flow - claim a page, add your links, then paste that one URL into your Instagram bio using the steps above.
- Go to the IShort dashboard and sign in with a free Google account.
- Claim your username - your public page lives at ishort.pro/yourname (3-24 characters, lowercase letters, numbers, or underscores).
- Add your links (up to 20), each with a title and URL. Drag to reorder them, and add your Instagram, YouTube, X, LinkedIn, and website as social icons.
- Pick a theme - five presets or a custom color scheme - then set your display name, bio, and avatar.
- Copy your ishort.pro/you URL and paste it into your Instagram bio's Links field (see the steps above).
Because it is one stable URL, you never have to edit your Instagram bio again - just update your links inside the page and changes appear to visitors within about a minute. The page works right inside the Instagram in-app browser, and it adapts to each visitor's light or dark mode. For more on this setup, see our guide to a link in bio for Instagram.
One more benefit: you can see which links your Instagram audience actually taps. IShort gives you free analytics - page views, link clicks, and click-rate over 7, 30, or 90 days, plus a per-link breakdown - so you learn what your followers care about. These are aggregate counts only; you never see who visited or where they are, and only you can view your own stats.
FAQ
What is a link in bio?
A link in bio is the clickable URL you can place in your Instagram profile, just under your bio text. Instagram does not let you make links clickable in captions or comments for most accounts, so the bio link is the one reliable place to send followers somewhere off Instagram - a website, a shop, a new video, or a link-in-bio page that holds several links at once.
Can you have more than one link in your Instagram bio?
Instagram gives you one website field in your bio, so you can only add a single URL directly. To share many destinations you point that one field at a link-in-bio page - for example a free ishort.pro page - which lists all of your links as tappable buttons. Followers tap your bio link and choose where to go.
Is a link-in-bio page free?
IShort Link in Bio is 100% free. You claim a page at ishort.pro/yourname, add up to 20 links plus social icons, pick a theme, and get click analytics on every link - with no paid plan or fees. You sign in once with a free Google account to manage your page.
Do links in Instagram captions work?
No. For most accounts, URLs typed into Instagram captions or comments show as plain text and are not clickable, so people would have to copy and paste them. That is why the bio link matters. If you want to understand caption links in detail, see our guide on Instagram clickable caption links.
