Parked domains and AdSense for Domains

For about twenty years the simplest search feed of all was a web address with nothing on it. This lesson explains how parked domains worked, because the logic still shapes the industry, and then what happened when Google closed the door.

What a parked domain is

A parked domain is a registered web address with no real website. Instead of an error, the visitor sees a page of links and ads related to the words in the address. Domain parking is the business of earning from those pages. The owner points the domain at a parking company, the parking company supplies the page and a search feed, and they split the revenue.

It is like owning an empty plot beside a motorway and renting it out for a billboard while you wait to sell the land. The plot earns a little every day from passing traffic, and you did not have to build anything.

Where the visitors came from

• Direct navigation. People typing an address straight into the browser, guessing that a generic word plus ".com" would be a real site.
• Expired domains. Addresses that once hosted a site and still receive visits from old links and bookmarks.
• Typosquatting. Misspellings of famous brands. This breaches trademark rules and parking policies, and has led to legal action.
• Domain redirect traffic. Visitors to one parked domain sold on and redirected to another advertiser's page.

Two ways to earn

AdSense for Domains

AdSense for Domains, AFD, was Google's feed for parked pages. Its origins lie in DomainPark, a product of Applied Semantics, which Google bought in 2003. AFD was mainly supplied through contracted parking companies such as Sedo, ParkingCrew, Bodis and others. Google opened a self-serve version to ordinary AdSense publishers in 2008 and retired that hosted version in 2012, leaving the contracted channel in place.

In arbitrage, AFD took on a second life. Operators bought social or native traffic and sent it to parked-style pages, sometimes passing keywords in the link. There was no article and no first screen of content. It was quick to set up and it monetised well, which is exactly why it drew advertiser complaints.

2025: advertisers opted out by default

Advertisers had long been able to exclude parked domains in their Google Ads settings, but few knew the option existed. In February 2025 Google told advertisers it would change the default over a series of months, so that accounts would be opted out unless they chose to opt back in. Trade press reported a start date of 19 March 2025 with later phases. This is the advertiser opt-out change that reshaped the sector.

The effect was a collapse in demand. An ad feed with no advertisers returns no ads, so coverage and RPC on parked pages fell together. By September 2025 Domain Name Wire reported that parking revenue had deteriorated quickly as the remaining advertisers were moved over.

February 2026: removed altogether

Google's Search Partner Network announcements page states that parked domains (AFD) ceased to be an ad surface in the network from 10 February 2026, and that the setting to include them was removed from advertiser accounts. System1's annual report notes that one of its Google agreements was ended by Google with effect from the same date.

1. An advertiser buys a keyword: A car leasing firm creates a search campaign in Google Ads and bids on “SUV lease deals”. It expects its ad to appear when people search for that on Google.
2. One setting widens the reach: Search campaigns include an option to show ads on Google’s search partners as well as Google.com. It is switched on unless the advertiser turns it off. It is all or nothing: partners cannot be picked one by one, only excluded.
3. The ad appears on an arbitrage page: A visitor on a partner site taps a related search for “SUV lease deals”. The firm’s ad appears in the results there, and a click costs it about $1.00 (illustrative), the same budget as a click on Google.com.
4. Does it convert?: What matters to the advertiser is the conversion rate: do these clicks become enquiries? Some partner traffic performs well. Where it converts less, Google says it lowers the price automatically (smart pricing), and invalid clicks are credited back.
5. Seeing where the ads ran: For years partner sites were a black box. Since 2025 Google has reported the individual partner sites where Search, Shopping, App and Performance Max ads appeared, so an advertiser can see each Placement by name.
6. Excluding what does not work: A site that spends money without results can be added to an account-level placement exclusion list, and ads stop showing there. The blunt alternative is the opt-out: switch search partners off for the campaign.
7. One whole category removed: Google went further with parked domains: advertisers were opted out by default in 2025, and on 10 February 2026 parked domains stopped being part of the search partner network altogether.
8. Why arbitrageurs should care: Every exclusion removes a bidder from that page, and fewer bidders mean lower prices. A page that sends advertisers real customers keeps its demand. A page that does not is slowly switched off, one exclusion list at a time.

Why Google did it

Google has not published a detailed rationale beyond its announcements, so what follows is the industry's reading. Parked pages offered the user nothing but ads. Advertisers increasingly asked where partner clicks came from, and Google was, in the same period, adding placement reporting and third-party brand-safety exclusion lists for search partners. A format with no content was the hardest to defend. RSOC, where the user reads something and chooses a term, was Google's preferred replacement.
