How do expired domains end up on media plans, and how do buyers catch them?
Part of MFA avoidance
The short answer
When a news outlet, school or charity lets its domain lapse, a new owner can buy the name and fill it with ad heavy or mass produced pages. The old reputation, links and category labels linger, so the domain can pass basic checks. Buyers catch the change by comparing today's content, sellers and site codes with the domain's past.
Key takeaways
- An expired generic domain passes through renewal notices, an optional grace period of 1 to 45 days and a 30 day redemption period before anyone else can register it, and a registrar may auction it during the grace period.
- Google's spam policies name expired domain abuse, with examples such as casino content on a former elementary school site.
- Category labels, popularity data and past reputation describe the old site for a while after the new owner arrives, so they can vouch for content they never saw.
- A changed ads.txt, new sellers.json names, new analytics codes and a gap in archived copies together point to a new owner; any one alone is a reason to look, not a verdict.
What happens when a respected domain expires?
A domain name is rented, not owned outright. For generic domains such as .com and .org, ICANN's Expired Registration Recovery Policy (opens in a new tab) sets the steps a registrar follows when a renewal is missed. The registrar must send at least two reminders, about one month and about one week before expiry, and another notice within five days after expiry if the name is deleted. Notices go to the registrant email on record, which is how a closed newsroom or a dissolved charity can miss them.
| Stage | What the policy says | Why it matters to a buyer |
|---|---|---|
| Before expiry | At least two renewal reminders, about one month and one week ahead | Reminders sent to an abandoned inbox go unread |
| Auto renew grace period | Optional, 1 to 45 days; the name may be available to third parties or auctioned by the registrar, depending on its terms | Ownership can change without the domain ever being deleted |
| DNS disruption | Registrars disrupt DNS for up to 8 days before deletion | The site goes dark, leaving a gap in archives and crawls |
| Redemption grace period | 30 days after deletion, during which only the old holder can restore it | A short window before the name becomes open to anyone |
| Release | The name can be registered again | A new operator inherits the name, its links and its history |
Country code domains, including .ca and .us, follow their own registry's rules rather than ICANN's recovery policy, so the timeline differs. The pattern a buyer cares about is the same: a name with years of reputation passes to someone who had no part in building it.
How are expired domains used for ad revenue?
Google's spam policies for Search (opens in a new tab) (updated August 28, 2026) define expired domain abuse as a case where "an expired domain name is purchased and repurposed primarily to manipulate search rankings by hosting content that provides little to no value to users." Google's examples are affiliate content on a site once used by a government agency, commercial medical products on a former nonprofit medical charity site, and casino content on a former elementary school site.
Search ranking is one payoff; ad revenue is another. A former local paper's name still draws links, bookmarks and some returning readers, and its old articles may still rank. A new operator can fill the site with mass produced articles, add ad slots and sell them through exchanges. The trade group definition of MFA sites (opens in a new tab) lists generic content, templated design and a high ad to content ratio among its signs, and a repurposed domain can show all three behind a name buyers once trusted.
Definition
- Repurposed domain
- A domain that lapsed or was sold and now runs content, ownership and monetization unrelated to the organization that built its reputation.
Why do old domains pass basic quality checks?
Some screening signals look backward. Google's Display & Video 360 help page on digital content labels (opens in a new tab) says its "brand safety classification is updated monthly to reflect any changes and updates to a site." Chrome UX Report popularity data on BigQuery, per the CrUX documentation (opens in a new tab), "is released on the second Tuesday of the following month," so the latest rank describes traffic from weeks earlier. A domain that changed hands recently can carry labels and ranks earned by its former owner.
Domain age misleads in a quieter way. A name that is renewed or sold during the grace period keeps its original registration date, so an old creation date in the registration record says nothing about who runs the site today. A name deleted and registered again starts a new registration with a new creation date. Treat age as background, never as evidence that the organization behind the name is still the same one.
| Signal | Why it can lag | What to check instead |
|---|---|---|
| Content category labels | Reclassified on a schedule; Google's DV360 labels are updated monthly | Read five recent articles yourself |
| Popularity rank | CrUX data arrives the month after the visits | Compare the rank with the volume of new content |
| Registration date | Unchanged when a name is renewed or sold before deletion | Registration events, contacts and name servers |
| Backlinks and reputation | Links from years of reporting stay in place | Whether today's articles match what those links describe |
| Past brand safety reviews | Done on the old site | A fresh review with today's date |
How can a buyer tell a domain changed owners?
No single record proves a change of owner, so the method is to collect several and look for a break. ICANN describes the free RDAP Lookup Tool (opens in a new tab) for reading registration data, but the Registration Data Policy (opens in a new tab), effective 21 August 2025, has registrars publish the registrant organization only when the holder agrees, and redacted fields are marked as redacted. A blank owner field is ordinary under that policy and proves nothing either way.
The advertising records are more telling. The ads.txt 1.1 specification (opens in a new tab) defines OWNERDOMAIN as the business domain of the entity that owns the site, explained in our guide to ads.txt OWNERDOMAIN. In sellers.json (opens in a new tab), the name field is the legal entity paid for the inventory. When the company paid for a domain's ad space changes, a buyer is looking at a new business.
Signs that a domain's owner has changed
- The ads.txt file was replaced wholesale, with new seller accounts and a different OWNERDOMAIN or none.
- The sellers.json entries for the site's direct accounts name a different company than a past snapshot.
- Analytics and ad code IDs on the pages differ from those in archived copies.
- Archived copies of the homepage stop for weeks, then resume with a new design.
- Bylines, staff pages, the masthead or contact details have disappeared or turned generic.
- Topics shifted, for example from county news to casino, loans or product roundups.
- Old article URLs redirect to the homepage or return errors while new articles appear daily.
What should happen to a repurposed domain on a list?
Treat the domain as a new site, not an updated one. The earlier approval was for a different business, so it no longer applies. Pause the domain on active inclusion lists and deals, record the evidence with dates, and either run a full review from scratch or move it to the exclusion list. Google Ads lets advertisers exclude placements (opens in a new tab) by domain, subdomain, path name or individual page, and a repurposed site calls for the whole domain.
Handling a domain that changed hands
- Pause it everywhere it runs. Remove the domain from active inclusion lists and deal lists for every client, not only the brief that surfaced it.
- Write down what changed and when. Save the old and new ads.txt, sellers.json entries and screenshots with dates.
- Review it as a new candidate. Apply the same content, layout and selling path checks as any unseen site, with no credit for its past.
- Record the outcome in the list history. Note the change of owner as the reason, so a later planner does not restore the old approval by mistake.
- Set a date to look again. A new owner can build a real publication, and a fresh review can admit it on its own merits.
What does an expired domain review look like on a real brief?
Fictional example
A driving school's local plan in New Brunswick
A fictional driving school with locations in Moncton, Fredericton and Saint John asks its agency for display beside local news, community events and road safety content, in English and French. The agency reuses a New Brunswick local news list approved two years earlier.
One domain on that list belonged to a weekly community paper. Its category labels still read as local news and its popularity band looks normal. The planner opens five recent articles and finds product roundups and celebrity slideshows with no local bylines. Archived copies of the homepage stop for six weeks and resume with a new design, and the ads.txt now lists different seller accounts with no OWNERDOMAIN line.
The planner pauses the domain on every client list that carries it, saves the old and new ads.txt with dates, and moves it to the exclusion list with a note that the original paper no longer runs it. The rest of the old list gets a fresh content check before the driving school's plan goes out.

Frequently asked questions
Is buying an expired domain against the rules?
Registering a released name is part of ICANN's normal lapse process, and a new owner can build a real site. Google's spam policy targets repurposing an expired name primarily to manipulate rankings with content of little or no value. For a buyer the question is whether today's site meets the plan's standards, judged without credit for its past.
Can a domain change owners without expiring?
Yes. Domains are also sold privately, and ICANN notes that a registrar may auction an expired name during the auto renew grace period, depending on its terms. In both cases the registration date can stay the same, so content, sellers and site codes are better evidence than the record's age.
Do Google ads appear on parked domains?
Not through Google's Search Partner Network. Google's parked domain glossary entry (opens in a new tab) says parked domains ceased to be an ad surface within the Search Partner Network effective February 10, 2026, and the option to include them in content suitability settings was removed. A lapsed domain can still sit parked for a while before a new owner fills it with articles.
Should a buyer exclude a domain because its registrant is hidden?
No. Under ICANN's Registration Data Policy the registrant organization is published only when the holder agrees, so a hidden owner is ordinary. Exclusion should rest on what the site publishes and how it sells, not on missing registration fields.
