Public Interest Registry does not guarantee its accuracy. Users accessing the Public Interest Registry RDAP service agree to use the data only for lawful purposes, and under no circumstances may this data be used to: a) allow, enable, or otherwise support the transmission by e-mail, telephone, or facsimile of mass unsolicited, commercial advertising or solicitations to entities other than the registrar's own existing customers and b) enable high volume, automated, electronic processes that send queries or data to the systems of Public Interest Registry or any ICANN-accredited registrar, except as reasonably necessary to register domain names or modify existing registrations. When using the Public Interest Registry RDAP service, please consider the following: the RDAP service is not a replacement for standard EPP commands to the SRS service. RDAP is not considered authoritative for registered domain objects. The RDAP service may be scheduled for downtime during production or OT&E maintenance periods. Queries to the RDAP services are throttled. If too many queries are received from a single IP address within a specified time, the service will begin to reject further queries for a period of time to prevent disruption of RDAP service access. Abuse of the RDAP system through data mining is mitigated by detecting and limiting bulk query access from single sources. Where applicable, the presence of a [Non-Public Data] tag indicates that such data is not made publicly available due to applicable data privacy laws or requirements. Should you wish to contact the registrant, please refer to the RDAP records available through the registrar URL listed above. Access to non-public data may be provided, upon request, where it can be reasonably confirmed that the requester holds a specific legitimate interest and a proper legal basis for accessing the withheld data. Access to this data can be requested by submitting a request to WHOISrequest@pir.org. Public Interest Registry Inc. reserves the right to modify these terms at any time.

The Quantcast Measure dataset
Every site we've detected as running Quantcast Measure, with version, hosting, country, TLD and traffic rank.
Quantcast Measure lives inside 2 datasets
Quantcast Measure detection is part of Technologies (€159/mo) and All data (€599/mo). Buy either to filter the full 105,320-site list, or grab a free preview first.
About Quantcast Measure
The geography of Quantcast Measure does not match the product. Quantcast built an audience measurement network for advertising buyers, and the pixel that feeds it was free for any publisher to install, yet as of September 2026 the tag appears on 105,320 sites of which Japan accounts for 95,382. A skew that extreme is never a national preference for a measurement vendor. Concentrations like this come from a platform: one blog host, one site builder or one advertising template that shipped the tag in a default theme, and every site created on it inherited the pixel whether or not the owner ever opened an account.
So the honest reading is that there are two populations here and the dataset does not label them. One group are publishers who deliberately installed the Quantcast Corporation pixel to get free audience demographics they could show to advertisers, which was the trade the product was built on: contribute measurement data, receive an audience profile that makes your inventory sellable. A larger group, on current evidence, carries the tag because a platform put it there. Anyone treating the whole file as a list of advertising-funded publishers will be wrong more often than right.
Filtering fixes it, and filtering is exactly what a list makes possible. Cross-referencing this column against country, TLD and the other tags on the same domain separates the groups cheaply. A site running the pixel alongside an ad server, a paywall or a newsletter platform made a decision. A site running it alongside nothing else, on a shared platform domain, did not. Working that filter needs the full population in front of you, which is the practical difference between a download and a lookup that confirms one domain is measured.
The tag dates to 2006 and is a Freemium Analytics service embedded as JavaScript, so detection is a simple script match and is dependable about presence. Dependable about presence is not the same as dependable about use. Tags stay in templates long after an account lapses, and Quantcast has changed shape repeatedly as an advertising business, so a live pixel is not proof of a live measurement relationship. .com leads the domain breakdown, which in a population this concentrated tells you more about where the hosting platform sells than about the audiences being measured.
Ad tech vendors sizing a competitive footprint, publisher sales teams looking for comparable inventory, consent and privacy auditors enumerating third-party trackers in a national market, and anyone doing diligence on what reach the network still has all want the same file rather than the same single answer. The value sits in the joins between columns, not in any individual row.
