Nielsen Online Measurement Products Privacy Policy

Nielsen has several products that measure and analyze online activity to offer insights into consumer behavior.

Nielsen Online Campaign Ratings Measurement

Nielsen works with various data providers to measure the effectiveness and reach of online advertising campaigns. As a result, advertisers are able to better understand campaign performances across both a TV and online audience. With this system, advertisers can learn if their ads were shown to the right types of people, just like a TV ad.

Here’s how it works: Advertisers tag their ads and then place them on their chosen sites around the web. When the ads are displayed, the tags make a call to a data provider, which then searches its own user database to find the age and gender that it has on file for that member. This age and gender information is sent back to Nielsen in an aggregated form. Nielsen is then able to report to the advertisers the age groups and gender of users to whom their ads for a particular campaign were displayed. A sample report might be "the ad was viewed by 5 million females between the ages 24-30."

All of this happens while protecting the privacy of both the advertisers and data providers’ users. The ads do not pass identifiable information about the campaigns to the data provider and the data provider does not pass personally identifiable information about its users to Nielsen. The technology utilized in this process uses standard browser cookies and Web beacons that do not contain any personally identifiable information.

This aggregated demographic information is retained only as long as needed for the purposes described in this notice.

We currently work with the following data providers. Please review each data provider`s privacy policy to learn more about their respective privacy practices.

Nielsen Web Analytics Products

Nielsen provides various other analytics and online measurement services to understand, and to help others understand, how people use and interact with the Internet in the United States and throughout the world. We do this by gathering research data on the traffic and users on our clients' websites and about their advertising campaigns.

Nielsen is able to gather this research data in different ways.

What information do we collect?

We gather statistical information on behalf of our clients. This information may include:

  • The number of visitors to their websites
  • The total audience exposed to an ad campaign and the demographic composition of that audience
  • Which pages or portions of pages (such as Web videos) are visited
  • The duration of page/video views
  • Advertising click-through metrics and advertising effectiveness metrics
  • The sites the users were visiting before they accessed our clients’ websites, and
  • Details about the browsers the visitors were using

We also administer surveys to some users of our clients' websites while they are visiting those websites. These surveys request additional demographic, non-personally identifiable information. Participation in surveys is always voluntary, and users choose whether or not to provide the requested survey information.

What technologies do we use to collect information?

Most of our online measurement services use regular cookies to gather statistical information to help understand what users find interesting and useful on our clients' websites, what advertising campaigns are effective, and the aggregated demographic composition of a website’s visitors or of the users that viewed an ad campaign. You can control these cookies through your browser’s settings and can opt out as described below. Alterations to these settings may, however, affect the functionality of certain web sites. Our VideoCensus product uses Flash cookies to study users’ interactions with streaming video online, e.g., whether they pause or stop them. For information about how to delete the Flash cookie, please click here.

We also embed a piece of code (sometimes referred to as "1x1 clear pixel," "Web beacon" or "clear GIF") in the pages of certain client websites in order to gather additional statistical site usage information. These pieces of code may also be embedded in client ad campaigns appearing on ad placements across many websites.

How do we use this information?

We use statistical information to provide our clients with detailed reports and analyses of traffic to their websites, the audiences of their websites and advertising campaigns, and the effectiveness of their advertising campaigns. We use the information collected in surveys in conjunction with information gathered through our cookies and code, in order to provide our clients with an even more detailed understanding of their Internet audience.

Nielsen may also combine the information collected on our clients' websites with other online and offline data sources and research tools, including non-identifying Nielsen panelist viewing. The other data sources may also include social media or ecommerce sites. These additional sources allow us to perform more robust research and analyses concerning Internet audience demographics, behavior and use.

Only non-identifiable or aggregated data are included in our reports.

With whom do we share information?

We employ or contract with other companies or individuals to perform certain functions on our behalf. Such companies or individuals may be provided with access to your information needed to perform their functions, but are prohibited from using such information for any other purpose. In addition, we may release information to third parties when disclosure is required by law or when necessary or desirable to exercise or preserve our legal rights, or to take action regarding potentially illegal activities. If all or part of our company is sold, merged or otherwise transferred to another entity, your information, whether personally identifiable or otherwise, may be transferred as part of that transaction.

How do we protect this information?

We store the information described in this policy for as long as needed for market research purposes as described in this policy. We may store these data in the United States or we may transfer them to another country. Wherever we hold the data, we will apply the terms of this policy and any applicable law. Nielsen has implemented certain security measures to help protect the security and confidentiality of information while controlled by us.

We limit access to your information to employees and agents who we believe reasonably need to come into contact with that information, all of whom are bound by this privacy policy. Access or use of information for any purpose other than those explained in this privacy policy will not be authorized.

Opting Out

If you do not wish to participate in any of Nielsen’s online measurement research, please click here to receive an opt-out cookie.

Please note: if you regularly delete your cookies, you will need to opt-out each time you delete your cookies.
