Link in Bio with a Custom Domain: Why and How (2026)

What a Custom Domain Means for Your Bio Link

Without custom domain, your bio link is at the platform's URL ??” linktr.ee/yourname, beacons.ai/yourname, unil.ink/yourname. With custom domain, your URL becomes links.yourname.com or shop.yourname.com or whatever subdomain you pick on your own domain.

Same page, same content ??” different URL. The platform still hosts the page; visitors just see a URL on your domain instead.

Why Use a Custom Domain

• Trust. Some users hesitate to click unknown short URLs. A domain matching your brand name lowers click hesitation.

• SEO. Slightly better SEO authority on your domain than a third-party platform domain.
• Memorability. links.yourname.com is easier to remember than linktr.ee/abc-xyz-name.
• Email matching. If your email is at yourname.com, visitors expect your bio link to be at the same domain.

Plus the domain itself (~$10-15/year regardless of platform).

Common Setup Issues

• DNS propagation delay. CNAME changes can take up to 48 hours to propagate globally. If verification fails immediately, wait an hour and retry.
• Wrong CNAME target. Each platform has its own target value. Don't copy-paste from another tool's instructions.
• SSL certificate provisioning. The platform auto-issues a Let's Encrypt cert; this can take 5-30 minutes after DNS verifies.
• Conflicting A records. If you have an A record for links already, remove it before adding the CNAME.
• Apex domain restrictions. Some registrars don't support CNAME on the root domain (yourname.com alone). Use a subdomain (links.yourname.com) or use ALIAS / ANAME records.

What Happens to Your Old Platform URL?

Once you set up a custom domain, the platform-branded URL (linktr.ee/yourname) still works ??” it redirects to your custom domain. Visitors using the old URL get to the same page. You don't have to update existing posts or share links retroactively.
