Shared link domains,
explained.
By the peekin team. Updated . 4 minute read.
A shared domain is one address used by many people, like a link service's main domain with your name after it. Platforms judge addresses as well as pages, so you share in the reputation of everyone else on it. Your own domain carries only your own record.
What counts as a shared domain
Most link pages give you an address on their own domain, with your name as a path or a subdomain. Everyone on that service shares the same domain. Some services also run extra "mirror" domains that many creators share.
Link shorteners are shared domains too. So are free website builders that give you a subdomain. The pattern is the same: one domain, many unrelated owners.
Why platforms judge addresses
Spam and abuse filters work at more than one level. They look at the page, and they look at the domain. A domain that has hosted a lot of reported or restricted pages builds a poor record, and new pages on it start from that record rather than from zero.
This is how email and web filters have worked for a long time, and it is reasonable to expect social platforms to do something similar. Meta does not publish the details of how it rates domains, so we cannot tell you how much weight it carries. We can tell you the direction: a domain shared with thousands of adult pages is not a neutral starting point.
The specific problem for adult creators
On a mainstream link service, most pages are fine. But a service that welcomes adult creators will, by design, host many adult pages on one domain. That is exactly the cluster a filter learns to recognise.
If one page on the domain is reported, it does not directly affect yours. If the domain as a whole is judged, it affects everyone on it, including people who did nothing wrong. You have no control over that and usually no warning.
What your own domain changes
- Its record is yours alone. Nobody else's reports land on it.
- You can move it. If you change link page provider, you point the domain at the new one and every posted link keeps working.
- It reads as you. A clean, personal address looks more trustworthy to fans than a service name.
It does not fix a page that gives its destination away, and it does not change anything about your posts. It removes one signal. See custom domains for OnlyFans for how to choose one.
When a shared domain is fine
If you are not linking anything adult, a shared domain is usually fine. Millions of people use them without issue, and a free page on a big service is a perfectly good choice for a shop or a band.
If you are an adult creator just testing the waters, a free shared page can still be a reasonable first step. Just know what you are trading, and plan to move to your own domain before the link carries real income.
On peekin, a page with no domain of its own goes live on a shared address too, but a small one. One address shared by everyone is the risk, so we spread creators across many small addresses, cap each one, check them daily, and move you in a tap if one is ever flagged. Your own domain is still the safest place for your link, because it removes the neighbours entirely.
A spare domain, for emergencies
Even your own domain can be flagged or blocked. Having a second one ready shortens the outage. On peekin, a spare domain is set up and secured in advance, shows nothing until you switch, and when you do, the old address is retired rather than forwarded, so a flag cannot follow you. It uses one of your plan's domains.
Every plan goes live on a shared address, included. Your own domain is not included in any plan: bring one you own for free, or buy one from £7 a year (£14 on Starter). See how to buy a domain for your link page.
How to tell if your current link is shared
Look at the address in your bio. If it is the name of a service followed by your name, such as service.com/yourname or yourname.service.com, it is shared. If it is a name you bought, such as yourname.link, it is yours.
Some services show your own domain to fans but still send them through a shared address when they tap. Tap your own link and watch the address bar. If it passes through a domain you do not own before reaching the platform, that domain is part of your link too.
The free scanner reports whether a page sits on a shared host with other adult pages, as one of its nine checks.
What happens if a shared domain is blocked
If a platform blocks a shared domain, every page on it stops working from that platform at the same moment. Fans tap and see an error or a warning. You cannot appeal it for your page alone, because the block is not about your page.
Your only fix at that point is to change the link in your bio, which brings back every problem in our guide to moving your link page. On your own domain, the same event would affect only you, and only if your own page caused it.
Asked most often.
Is linktr.ee a shared domain?
Yes. Every free Linktree page sits on the same domain with a different path. That is true of most link services unless you connect your own domain.
Does a custom domain stop my account being restricted?
No. It removes one signal, the shared address. Your posts, profile and link page still count.
Can I bring a domain I already own?
Yes, on most services that support custom domains. On peekin, connecting a domain you own is free.
Check your own page first
The scanner reads any link page the way Meta's crawler does and runs nine checks. It is free and needs no account. If you want a page built this way, the plans start at the price on the pricing page.
