The rule, in one sentence
Any domain you ever pointed at a site you still own has to stay registered until you no longer own that site. Forever. Not 'until the redirect stops sending traffic.' Not 'until I forget about it.' Forever.
The reason is uncomfortable: once a 301 is in place, the receiving domain's authority is partially dependent on the redirecting domain's continued existence. Drop the redirect source and you don't just lose new traffic from it — you hand the equity it was passing to whoever catches it next. The domain forwarding explainer covers the underlying mechanics.
How catchers actually work
Expired-domain monitoring is a small, mature industry. SpamZilla, ExpiredDomains.net, NameJet, GoDaddy Auctions, DropCatch — all of them watch for domains entering the expired pool, and a subset of their users specifically filter for domains that currently have 301 redirects pointing into other properties. The aged-domain value guide covers what makes those captures attractive.
The reason that filter exists: a domain with an active redirect into a high-authority site is a more valuable buy than a comparable domain without one. The buyer can keep the redirect (and inherit whatever equity was flowing), kill it and host new content, or repoint it at a different target.
From the original owner's perspective, all three of those outcomes are bad. The first dilutes whatever effect you were getting because now a stranger controls the on-ramp. The second cuts the equity off. The third actively redirects link equity that used to flow to you into a different site — possibly a competitor. The parked-domain stack explainer covers how to set up routing once you have decided to keep an inherited domain alive.
The math, plainly
The ratio is absurd and the decision is not close. Every dollar you save by letting a redirect source lapse costs you between $40 and $400 in equivalent replacement effort.
Why people let domains drop anyway
Three patterns explain almost all of it:
One: the email at the registrar is a personal Gmail nobody checks anymore. Renewal notices go to /dev/null. The domain expires silently. By the time anyone notices, the catcher has already filed the trademark complaint to keep it.
Two: the credit card on file expired. Auto-renewal fails. The grace period runs out. Same outcome.
Three — the worst one — the redirect was set up by someone who no longer works at the company, and nobody on the current team knows the domain exists, let alone what it's doing.
What 'multi-year prepay' actually buys you
ICANN caps single registrations at 10 years. That's the longest you can prepay any domain at once. Most registrars let you stack — you can renew a domain currently expiring in 2027 out to 2037, then renew it again in 2030 out to 2040.
Doing this once a year, as part of the audit, costs roughly the same as the original renewal but pushes your expiration risk window from 12 months out to a decade. The renewal-notice email going unread no longer matters — the next risk is 10 years away, not 30 days.
For domains that are doing real work — meaningful inherited equity, brand defense, or active 301s — multi-year prepay is the closest thing to 'set and forget' you can buy.
When to actually let a domain drop
There is one case: a domain you registered, never used, never linked from anywhere, and that has never had inbound backlinks of any kind. Those have no inherited equity and can drop without consequence.
Everything else — any domain that has been live, any domain you redirected, any domain that ever held content — is on the renew-forever list. The $12 is not the point. The point is that the alternative is paying $5,000 to a link agency to replace what you just gave away.
Before deciding which inherited domains are worth the renewal, run the domain appraisal calculator and read the DNS / Workers / 301 vs 410 walkthrough for the routing decision.
