There is a real difference between sending people to a long shared address and sending them to your own name dot com. One looks borrowed; the other looks like a business. But the case for a custom domain is bigger than a first impression.
Here's when it's worth doing, and what it actually buys you.
It looks like you mean it
A clean domain signals permanence and care. On a business card, in a video, said out loud, yourname.com is easier to trust and easier to remember than a string of characters after someone else's brand.
You own the address, not just the page
This is the part people miss. If you build your audience on a shared link and later switch tools, every one of those links breaks. With your own domain, you can move the page underneath it and every printed card, bio and post still works.
- Your links keep working even if you change platforms.
- You aren't advertising someone else's brand for free.
- It's yours to redirect wherever you need over time.
It compounds your brand
Every mention of your domain is a small deposit in the same account. Say it in every video and print it on every card, and the name sticks. A shared slug spreads someone else's brand instead of building yours.
When to skip it
If you're just testing an idea this week, the free shared link is completely fine — get the page working first. Add the domain once you're serious enough that you'd hate to lose the address.

What a Domain Actually Changes, and What It Doesn't
A custom domain — yourname.com instead of a shared address with someone else's brand in it — changes two real things: how the link looks when you say it or print it, and who owns the address if you ever move tools. It does not, despite the folklore, meaningfully lift your Google ranking or make the page load faster. Being honest about that saves you paying for benefits you won't receive.
Where it genuinely earns its keep is off-screen. On a business card, a market-stall banner, a podcast read-out or the back of a van, 'onesol.io/yourname' is fine but 'yourname.com' is easier to remember and read back. If most of your traffic is people tapping a link inside an app, the domain matters far less; if you hand your address to people in the physical world, it matters more.
The underrated benefit is portability. Because the domain is yours, you can point it at one tool today and a different one in two years without reprinting a single card or losing anyone who bookmarked it. The address becomes an asset you control rather than a line you rent.
Setting One Up Without a Support Ticket
The mechanics are less frightening than they sound. You buy the domain from any registrar, then add one DNS record that points it at your link-in-bio page. Most people should use a subdomain such as 'link.yourname.com' or 'go.yourname.com', which needs a single CNAME record and leaves the bare 'yourname.com' free for a proper website later.
Give the change time before you decide it's broken. DNS updates can take anywhere from a few minutes to a day to propagate, so if the link doesn't work immediately, wait a few hours rather than piling on more records and confusing things. Once it resolves, load the page on your phone off Wi-Fi to confirm it works on a normal connection, not just at your desk.
- Buy the domain from any registrar — the cheapest plain .com is fine
- Add the CNAME record your link tool specifies, usually on a subdomain
- Wait for it to propagate before touching anything else
- Confirm the padlock (HTTPS) shows before you share the link
Choose a Name You Can Say Down a Phone Line
The test for a good bio-link domain isn't how it looks in a logo — it's whether you can say it to someone across a noisy room and have them type it correctly. Hyphens, creative spellings and swapping numbers for letters all fail that test. 'sarahbakes.com' survives being spoken aloud; 'sarah-bakes-co.link' does not.
Be wary, too, of the unusual endings that look cheap for the first year and quietly renew at a premium. A plain .com or .co is worth a little more up front for how ordinary and trustworthy it reads; a novelty ending can look like spam to exactly the people you're trying to win over. If the .com of your name is taken, adding your craft — 'sarahbakes.com' over a strange ending — usually wins.
One last check before you buy: say the full address out loud, then ask a friend to write down what they heard. If it comes back exactly right, you've found your domain. If they add a hyphen you didn't mean or guess the wrong ending, keep looking — you'll be repeating this address for years.
