A link in bio with your own custom domain, registered and connected for you
A link in bio with a custom domain is the difference between sending people to an address on someone else's site and sending them to one that is yours. It is the address you say out loud in a video, print on a card and type into a bio that has very few characters to spare.
On Pro, we register the domain and connect it to your page. You do not paste DNS records, you do not change nameservers, and you are not left comparing an A record against a CNAME at midnight because a help article assumed you knew which one you needed. You choose a name and the page answers on it over https.
Pro is 29 euro a month or 290 euro a year and also includes analytics and per-link geo filtering, with a 7-day free trial and a 30-day money-back guarantee. Your heybio.io/yourname address keeps working alongside the new domain, so nothing you have already posted breaks.
What actually happens when you add a domain
You tell us the name you want. We register it, connect it to your page, and the page is served over https on that address. That is the whole process from your side.
The parts people get stuck on are the parts you do not touch. DNS records are the classic one: an incorrect record type, a typo in a value, or a change made at a registrar that will not show up for hours, all producing a page that either does not load or loads with a browser warning that scares visitors away. Certificates are the other one, and a link page that throws a security warning is worse than no link page at all.
Because the connection sits on our side, there is also nobody to coordinate with. You are not opening a ticket with a registrar, waiting on a reply, then opening a second ticket with your page host when the reply does not help.
Custom domain or heybio.io/yourname
Both work, and you keep both. The question is what you tell people to type.
A custom domain reads as a business rather than as a page on a service. It is shorter in a bio where every character counts, it is easier to say out loud in a video without spelling out a slash, and it survives changes in your tooling. If anything about your setup changes later, the address people memorised is one you control.
There is a claim we are not going to make. A custom domain will not make Instagram or TikTok treat your link better, and nobody can promise you it will. A newly registered domain has no history behind it, which cuts both ways. What you are buying is control and presentation, and those are worth buying on their own terms without a ranking story attached to them.
Choosing a name that still works in two years
Pick something short. Every character is one more thing to mistype and one less character in a bio that is already tight.
Say it out loud before you commit. If it needs spelling when you mention it in a video, it is the wrong name. Hyphens and digits are the usual culprits, along with word pairs that run together into something you did not intend when the spaces disappear.
Match your handle where you can. One name across your profile, your page and your address is one thing for people to remember instead of three.
Avoid naming yourself after something narrow. A domain built around one platform, one offer or one city becomes a problem the moment you move on, and moving means editing every bio, every video description and every profile you have ever set up, and losing whatever anyone bookmarked.
Everything else works the same on your own domain
A custom domain changes the address, not the behaviour. Clicks arriving from inside the Instagram or TikTok in-app browser are still pushed out to the device's real browser, and the rescued-click count still appears in your dashboard.
Analytics carry on reporting visitors, clicks per button, referrer, device, country and hour of day. Per-link geo filtering carries on hiding or showing individual buttons by country, and still fails closed when a visitor's country cannot be determined.
The share card stays neutral with no photo on it. Outgoing links are still checked before they go live: https only, no crypto domains, no shorteners, and the brand has to match the destination. Changes are still versioned with one-click rollback, and a full export of the page and its images is still available. Nothing becomes conditional on which address the visitor used.
What a custom domain will not do for you
It is not an SEO trick. A fresh domain with one page on it does not arrive with authority, and if someone sells you a link page on the basis that a custom domain will lift you in search results, they are selling you something they cannot deliver.
It will not stop a platform reviewing or classifying your link. Those decisions are made by systems we have no access to and no influence over, and they change without announcements.
It will not repair a page that is not converting. If the first button is wrong or the headline says nothing, a better address does not fix it, and Pro analytics will tell you that faster than a domain will.
What it does do is real: an address you control, cleaner in a bio, easier to say, and stable if anything else about your setup changes.
Questions
Who holds the domain registration?
The domain is registered and connected as part of your Pro plan, so you do not deal with a registrar. If you need it held in your own registrar account, or you want to be able to move it elsewhere later, raise that with support before you upgrade so it can be set up that way from the start rather than changed afterwards.
Can I use a domain I already own?
The Pro custom domain is designed around us registering and connecting the name for you, which is the simplest path. If you already own a domain you want to use instead, contact support before upgrading so we can confirm it can be pointed at your page and tell you what it needs from your side.
How long before the domain works?
The connection on our side is quick, but domain registration and DNS propagation across the internet are not instant everywhere and we are not going to quote you a number we cannot hold to. Your heybio.io/yourname address keeps working throughout, so there is no window where your bio link is dead.
Does the custom domain replace my heybio.io link?
No, both addresses keep working. That matters because your old link is already sitting in video descriptions, old posts and other people's messages. You can start using the new domain everywhere going forward without going back to fix anything you have already published.
What happens to the domain if I move off Pro?
The custom domain is a Pro feature, along with analytics and geo filtering, so those go with the plan. Your page itself keeps working at heybio.io/yourname, and a full export of the page and its images is available at any point, whichever plan you are on.
Pick the name you would be happy saying out loud in a video, and we will register and connect it for you on Pro.
