Nielsen uses its proprietary digital measurement products to measure and analyze how consumers engage with media across online, mobile and emerging technologies.
We work with various companies, including data providers, advertisers, advertising agencies, and publishers, to measure the effectiveness and reach of content viewed or listened to online and offline, no matter what kind of device people use to consume it. For example, we help advertisers better understand campaign performances across TV, radio, computer and mobile audiences.
Here's how it works: participating companies include proprietary Nielsen measurement software in their content (e.g., audio, video, ads, and any other media consumers might engage with or encounter) on their chosen sites, ads, apps and video players. Nielsen’s proprietary measurement software embedded in the content uses various technologies (including cookies, pixel tags, and our software contained in mobile applications) or watermarks to gather information that help us understand what content users are watching or listening to and interact with, which advertising campaigns are effective, and the aggregated demographic composition of a website's or application's visitors or viewers of digital content. For example, a sample audience measurement report might say "this ad campaign was viewed by 24,000 females between the ages of 24-30 in the U.S., Pacific Northwest region."
We also work with third-party service providers to obtain pseudonymous and/or aggregated data, which we add to our measurements. "Pseudonymous data" means personal data from which the underlying individuals cannot readily be identified. Types of pseudonymous data include information associated with, for example, a cookie, advertising or device identifier, or other persistent unique identifier. "Aggregated data" means a set of data about a group or segment of individuals that prevents specific individuals from within the group from being identified.
Sometimes our mobile measurement software is embedded in Adobe's Primetime, a "TV Everywhere" platform that enables consumers to watch live, linear and on-demand programming on different devices. Learn more about and read the .
Nielsen audience measurement products and Nielsen Marketing Cloud use different solutions. Nielsen does share a limited amount of device or browser-linked non-identifiable or aggregated data between these two separate Nielsen product lines to help them each function better and more efficiently, but audience measurement data is not directly used to help place online ads. For more information about how the Nielsen Marketing Cloud collects and uses data, please read the Nielsen Marketing Cloud Privacy Statement.
We do not identify, or attempt to identify, the individuals we collect content measurement data from or about.
Our proprietary digital measurement software may collect data about the content that was viewed (e.g., which ad campaign or which program episode), where the content was viewed (e.g., on which website or in which app), and general information about the device on which the content was viewed (e.g., tablet or smartphone, advertising identifier, IP address, or operating system). We then match that data with data from other companies that recognize their own users or that collect data about consumers generally. These other companies provide Nielsen with aggregated or pseudonymous audience statistics. We do not tell these third parties what content their users have viewed, and Nielsen never learns the identities of the other companies’ users.
Our Nielsen Digital Brand Effect services randomly present short surveys to users who may or may not have been exposed to our clients' content. Responses are voluntary. If a viewer responds to a survey question, the response is stored in a database. The surveys do not ask for or collect any directly identifiable data, but will collect an IP address and a device identifier.
We use this data to create a variety of insights, reports and analyses, including the composition of the audience that viewed certain content, or about the effectiveness of an advertising campaign.
We may also enhance or calibrate the data collected with other online and offline data sources and research tools, including Nielsen panelists’ viewing data (excluding individually identifying details). Other data sources may include social media or e-commerce sites. These additional sources allow us to perform more robust research and analyses concerning internet audience demographics, preferences and use.
We include only non-identifiable or aggregated data in our insights, reports and analyses.
We employ or engage other companies or individuals to perform certain functions on our behalf. These service providers are granted access to the data needed to perform their functions, but are prohibited from using our data for any other purpose. In addition, we may provide data to third parties when disclosure is required by law or as needed to exercise or preserve our legal rights, or to take action regarding potentially illegal activities, as well as in the event of a sale, assignment, bankruptcy, or other disposal of all or part of our business or assets (in which case we will take reasonable steps to ensure that the data is protected as described in this Privacy Statement). We may also share pseudonymous data to facilitate financing, securitization, insuring or other necessary business activities.
We use reasonable organizational, technical and administrative measures to protect the security and confidentiality of data under our control. Unfortunately, no data transmission over the internet or data storage system can be guaranteed to be 100% secure.
We store data for as long as needed for our research and analysis purposes as described in this Privacy Statement and in accordance with applicable law. We may store data in the U.S., or we may transfer them to another country. Wherever we hold data, we will apply the terms of this Privacy Statement and any applicable law.
We believe that you should have a choice about whether to contribute to our research and insights. If you are not currently a Nielsen panelist and do not wish to participate in Nielsen's digital measurement research, you may opt out on browsers .
With browsers, we use both regular HTTP cookies and HTML5 local storage. We keep in HTML5 local storage only a copy of the unique cookie ID assigned to our HTTP cookie that is placed on your device. When you opt out, our opt-out mechanism replaces the unique HTTP cookie with an "OPT_OUT" cookie and clears out the information Nielsen has placed in HTML5 local storage. If you delete all of your regular cookies (which would include your Nielsen HTTP "OPT_OUT" cookie), you will have to opt out again. Please note that because this is a browser-level opt out, if you use more than one browser, you will need to opt out in each. If you change your mind and want to participate in Nielsen's digital measurement research, you may . Note that the Safari browser no longer supports this functionality and will automatically delete our opt-out cookies after 24 hours. If you want to stay opted out from Nielsen measurement, we suggest that you use another browser.In the mobile app environment, we require each application that contains active Nielsen measurement software to disclose that Nielsen measurement is included in that app, and provide access to a Nielsen opt out. Please note that some of the older apps that contain Nielsen’s software are able to provide only an app-level and device-specific opt out. So, if you have more than one older mobile app that contains our software, or if you have the same older app on more than one mobile device, you will need to opt out in each app on each device. In newer apps, Nielsen offers a device-level opt-out. You need only to activate the “Limit Ad Tracking” (for iOS devices) or “Opt out of Ads Personalization” (for Android devices) option in your device’s settings. If you have the same newer app on more than one mobile device, you will need to change the settings on each device. The app’s privacy notice should make clear which type of opt out is available for Nielsen’s measurement software.
We reserve the right to update and make changes to this Privacy Statement. We will provide a description of changes since the last update in the “Recent Changes to this Privacy Statement” section.
