- Threads supports 1 clickable link in your profile bio (up to 80 chars of bio text + 1 URL).
- Settings → Profile → Edit profile → Link → paste URL → Save. Link becomes clickable across the Threads app and web.
- For multiple destinations (Instagram, YouTube, Substack, store), use a link-in-bio service like UniLink as your single Threads bio link.
How to Add a Link to Your Threads Bio
- Open the Threads app (iOS / Android) or threads.net.
- Tap your profile icon (bottom right).
- Tap Edit profile.
- Tap the Link field.
- Paste your URL (e.g.,
https://unil.ink/yourname). - Optionally add a title (Threads displays it instead of the raw URL).
- Tap Done.
The link appears below your bio text on your profile. Both your followers and non-followers can tap it.

Why Only 1 Link on Threads?
Threads inherited Instagram's "1 link in bio" philosophy. Meta's design wants users to focus on a single destination, not spam multiple URLs.
This is why link-in-bio services dominate on Threads (just like Instagram). One URL → infinite destinations behind it.
How to Sync Your Threads Bio with Instagram
Since Threads is owned by Meta, your profile picture and link can sync automatically:
- Settings → Privacy → Sync with Instagram.
- Toggle ON.
- Updates to your IG bio link will reflect on Threads (and vice versa, in some setups).
Caveat: Sync is one-way for some accounts. Test by updating IG and checking if Threads picks it up.
How to Make Your Threads Link Clickable
Threads automatically converts URLs to clickable links — both in your bio and in posts:
- Bio link: 1 URL, always clickable, with optional custom title.
- Posts: any URL is auto-clickable (unlike Twitter/X which sometimes hides links).
- Comments: URLs are clickable.
Threads doesn't penalize links in posts the way LinkedIn does. Drop links freely.
Best Links to Add to Threads
- Link-in-bio (UniLink, etc.) — covers all your platforms.
- Personal website / portfolio.
- Newsletter signup (Substack, ConvertKit).
- Latest project / launch.
- Podcast or YouTube channel.
- Online store (Etsy, Shopify).
How to Use Link Title for Better CTRs
Threads lets you show a custom title instead of the raw URL. Use this strategically:
- Raw URL:
https://unil.ink/yourname→ looks like a generic link. - Custom title:
"Get my free playbook"→ 5-10x higher click-through rate. - Action-oriented titles work best: "Join my newsletter", "Download free template", "Latest video".
Frequently Asked Questions
Can I add multiple links to my Threads bio?

Does Threads use Instagram's link?

Why is my Threads bio link not clickable?
