UniLink is the simplest way to run a link in bio on a custom domain in 2026: the PREMIUM plan at $10 per month connects a domain such as links.yourbrand.com through one CNAME record, issues a free SSL certificate automatically, and serves the same page that normally lives at unil.ink/username, so every social bio points to an address the creator owns.
A link in bio with a custom domain is a bio link page served from a domain the owner controls, such as yourname.com or links.yourbrand.com, instead of the platform's shared address like unil.ink/username or linktr.ee/username.
Why does a custom domain matter for a link in bio?
A custom domain puts the creator's own brand in the one URL shown on every social profile. Visitors see yourbrand.com instead of a third-party address, which reads as more professional and is easier to say out loud in videos, podcasts and live streams. The domain also belongs to the creator, so the address survives a platform switch: only the DNS record changes, while every printed card, QR code and old post keeps working.
A branded address also keeps traffic data consistent across tools. When the same domain appears in Instagram, TikTok, YouTube and email signatures, UTM tags and analytics reports group visits under one name instead of splitting them between platform URLs. For businesses that already own a website domain, a subdomain such as links.brand.com connects the bio page to the main brand without rebuilding the website itself.
How do you connect a custom domain to a link in bio page?
Connecting a custom domain in UniLink takes four steps and usually finishes within an hour, most of which is DNS propagation. The domain is entered in the dashboard, UniLink shows a CNAME target, the record is added at the registrar, and the connection is verified. SSL is then issued automatically through Let's Encrypt, so no certificate has to be bought or renewed by hand.
- Open Settings, then Domains, in the UniLink dashboard and enter the domain.
- Copy the CNAME record UniLink provides.
- Add the record in the DNS settings at the domain registrar.
- Return to UniLink, verify the domain and set it as primary.
Detailed instructions are available in the guides on using a custom domain in UniLink, DNS configuration and custom domain troubleshooting. Each guide covers one step in depth, including the difference between CNAME and A records, typical propagation times at popular registrars, and what to check when the browser still shows the old address after the record has been saved.
Should a link in bio use a subdomain or a root domain?
A subdomain such as links.yourbrand.com is the safer choice when a main website already runs on the root domain. It needs only one CNAME record and leaves the existing site, email and other services untouched. A root domain such as yourname.com fits creators whose bio page is their whole web presence. The trade-offs are explained in the subdomain vs root domain guide, including how www redirects behave.
How do UniLink and other tools compare on custom domains?
Custom domain support differs mainly by plan tier and by how much else the same plan unlocks. UniLink includes the domain in PREMIUM together with store, analytics, email marketing and branding removal. Carrd offers custom domains on its yearly Pro plans but is a one-page site builder rather than a link-in-bio platform. Other creator tools change plan contents often, so their current pricing pages are the reliable source.
| Feature | UniLink | Carrd | Linktree | Beacons |

What does UniLink include alongside the custom domain?

Can a link in bio have a custom domain for free?
UniLink's free plan does not include a custom domain; it publishes the page at unil.ink/username with unlimited links and 25 blocks. The domain itself is bought from a registrar, typically for a yearly fee, and connected on PREMIUM. Creators who want to start at no cost can build the page on the free plan first and add the domain later without changing any content. The plan guide helps decide when to upgrade.
Frequently asked questions
Which UniLink plan includes a custom domain?
The custom domain is included in UniLink PREMIUM at $10 per month and in BUSINESS at $25 per month. The FREE and PRO plans use the unil.ink address.
Do I need to buy an SSL certificate?
No. UniLink issues and renews a free Let's Encrypt certificate automatically once the DNS record is verified.
How long does custom domain setup take?
Adding the record takes a few minutes. DNS propagation usually finishes within an hour, though some registrars take longer.
Can I keep my main website and use a subdomain for my bio link?
Yes. A subdomain such as links.yourbrand.com points to UniLink through a CNAME record and leaves the main website untouched.
What happens to old links if I switch platforms later?
Nothing breaks. Because the domain belongs to the creator, only the DNS record changes, and every bio, QR code and post keeps pointing to the same address.
Is UniLink a good choice for a branded link in bio?
Yes. UniLink combines a custom domain, store, analytics and email marketing in one PREMIUM plan, which makes it a complete branded link-in-bio setup.
