Quantcast Partners

Last Updated: December 8, 2022

We partner with other companies to help us provide and improve our services and products. Sometimes, it is necessary for us to share information that could be considered to be personal information about you with these partners. (Remember that we don’t share directly identifiable information about consumers, such as your name or address, because we do not collect that type of information, as discussed in our Products and Services Privacy Policy). 

Products and Services Partners

Listed below are the partners with whom we share information in the provision of Quantcast’s products and services to our clients. This list identifies those partners, and lists links to their respective privacy policies and opt-out links so that you can learn more about their data collection and usage practices.

We are continually improving and updating our services and our partners will change over time. We will update this page to reflect those changes. Please visit our Products and Services Privacy Policy for more information about Quantcast’s data practices.

Please note that the links in the tables below are provided for your convenience. Each is solely maintained by the respective partner, and are subject to change at such partner’s discretion.

Ad Serving

The companies in this category serve digital advertisements on various digital platforms such as the web, social media, or mobile apps, and issue reports on the performance of advertising campaigns (e.g., the number of users who saw a particular ad, the particular ad type that was served, etc.). We need to use these vendors to deliver and measure the advertising campaigns that we serve. To do this, these vendors collect and use certain identifiers, such as the IP address of the visitor to the digital platform (e.g. to deliver the ad to that visitor’s browser or device) and an identifier specific to the advertisement (so they can identify the ad they need to serve and measure).

Ad Verification

These companies provide a technology to ensure that digital advertisements appear on intended sites and reach the targeted audience; examples include measuring the viewability of an ad, brand safety and fraud (e.g., whether a site is safe for the particular advertiser’s brand or whether it is a fraudulent site). We use these vendors in order to better meet the requirements of our clients and deliver more effective advertising. These companies collect and use certain identifiers, such as the IP address of the visitor to the digital platform and an identifier specific to the advertisement (so that they can pass these details to the ad server, if they determine it is appropriate for the ad server to deliver the ad).

We share online identifiers (e.g., cookie IDs) with them in order to sync identifiers to effectively integrate with their services.

Marketing and Customer Research
Quantcast works with companies to collect and analyze online behavior about Quantcast products for market research, customer satisfaction, website feedback and concept testing.
