How information collection on websites works:


Meet Maggie: To show how information is collected on Websites and across the internet, we’ll use Maggie as example. Maggie will help demonstrate one person’s journey on the web, and how we help make her online experience more meaningful and relevant.


Maggie is a 42 year-old mother of three who lives in a small town on Long Island, New York. Maggie likes to shop, research, and read content online, particularly about her gardening hobby. She uses email and social media and enjoys receiving advertising relevant to her interests so she can learn about new products and ideas. However, Maggie is concerned about her privacy and what data is collected about her. She often wonders how her computer knows she likes gardening when she sees gardening ads, even when she is not on a website about gardening. The data use practices below will help Maggie and others better understand just that. These practices explain who GroupM is and how we collect and use information in connection with the Website and GroupM Services. Website Privacy Practices


Before we get detailed on our privacy practices, we want to point out that we collect data in two different ways. This section talks about our data collection and use practices for this Website; later we will talk about data collection and use via services provided on behalf of our clients.


Collection and Use of Non-Personal Information (information that doesn’t identify you): When Maggie goes to, we automatically gather non-personal information (also known as non-PII) by placing a cookie,  or number, on her device. We do this to help understand what parts of our website Maggie enjoys most. This allows us to improve with content that Maggie prefers for future visits. We do not automatically collect or use any of Maggie’s personally identifiable information (PII) when she visits


Collection and use of Personally Identifiable Information (PII). We only use PII when a user voluntarily provides it. There are a few instances where we may collect PII from Maggie. But, we never collect PII without consent and never use PII in advertising or marketing placements. Examples where Maggie or other users might voluntarily provide PII include:


  • Responding to Maggie's requests: we keep a record of information, including email address and other PII solely for responding to a user’s request. For example:
    • If Maggie clicks on the “contact us” link and submits a question or comment, we will collect her name, email address, and phone number in order to send her a reply.
    • If Maggie voluntarily asks to be added to our newsletter list, we would collect her email address to send her our email newsletter.
  • Purchases: If Maggie were to purchase or subscribe to GroupM services for a fee via, information collected such as payment information would only be used for processing payment.


How to manage information we have about you and your subscriptions. If at any time Maggie decides she would like us to remove her from our marketing e-mails or newsletters, unsubscribe from our database, or if she’d like to change or correct any contact information, she can contact us at She must include her name, email address, and clear instructions regarding changes she is requesting, like the specific newsletter or mailing from which she would like to be unsubscribed. She may also unsubscribe from email newsletters by clicking on the “unsubscribe” link found at the bottom of the email.

GroupM uses cookies, pixels and similar technologies to collect Non-PII  about visits to our Website. A cookie is a file placed on a user’s browser that uniquely identifies browser and device. Cookies allow us to customize Maggie’s website experience to include more content she likes, and less content she may find not useful. If Maggie does not agree to our use of cookies, she may prevent their use through her browser settings, elect not to use this Website, or just opt out of cookies on our Website as described below. By opting out, Maggie may not be able to use certain Website features.


Sometimes a cookie resides on Maggie’s device for just the single time she’s visiting our website; this is called a session cookie.  Sometimes a cookie remains on Maggie’s device until she deletes it; this is called a persistent cookie. Both types of cookies may be used on our Website. Cookies help us analyze how users like Maggie use our Website by telling us the pages viewed. They also tell us about the number of visitors to the Website and the webpages that referred them. The Google Analytics cookie we use is an example of a persistent cookie.

California Online Privacy Protection Act Disclosures: California law requires us to tell you that GroupM does not authorize third parties to collect PII without separate consent by you, the user.

Interest Based Advertising (IBA) 


Remember Maggie and her gardening hobby? With Interest Based Advertising (IBA) technology, (also known as behavioral advertising or audience buying), Maggie will see more gardening ads online because she visits many gardening websites and reads a lot of online content about gardening. If our client is a Brand that sells gardening tools, GroupM’s Services will help place ads on sites where people who like gardening, like Maggie, will see them.


When Maggie visits websites, watches videos online, or clicks on ads, we store a number on her browser using a “cookie” or in the case of mobile apps, a “device ID” to remember her visits. Accomplished with partners (digital publishers such as online gardening magazines, for example), this cookie (number) will never collect personally identifiable information (PII) about Maggie. More on this a bit later…


Because many websites Maggie visits are related to gardening, the number which identifies her machine or device is put in the “gardening enthusiast” interest category. As a result, we may show Maggie ads that are relevant to gardening enthusiasts as she browses websites. This is how we use information collected about Maggie through the cookie (number). This is an industry standard approach; you can learn more about these practices at . Remember the cookie, or device ID does not tell us who Maggie is specifically. All we know is that someone used that particular device to view a gardening website. We tag the device with the cookie so we can later serve more gardening ads to that device.


NO PERSONAL INFORMATION is collected for IBA. So what do we collect?


Through the process described above, we do not collect any of her PII and do not know Maggie’s name or any other personal information. We simply recognize the cookie (number) stored in her browser which tells us someone likes gardening websites. We then show Maggie ads related to interests in gardening and based on inferred demographics associated with gardening. We will never show ads based on sensitive information categories such as those based on race, religion, sexual orientation, health, or sensitive financial categories.


Sharing this information and how online advertising works:


Maggie’s Non-Personal information (non-PII) collected through our Services (or ads placed by us on behalf of clients) may be shared with our clients and vendors. This is essentially how we do business and is how online advertising works. By sharing Maggie’s Non-PII with our clients and vendors, the information helps them deliver more tailored ads to potential customers. The non-personal information allows clients to best understand what ads Maggie likes most based on how she interacts with the ads and when. This also enables serving of personalized ads to Maggie’s devices so she sees ads relevant to her interests, hobbies and things she may be shopping for at the moment. This information also helps clients formulate more efficient ad campaigns which can help Maggie in the long run. We do not collect PII via our clients’ ads, except in instances where consent is given by you or you provide the PII voluntarily, and therefore, we do not sell, rent, or share personal information collected on with anyone other than as set forth in this Privacy Notice.


What to do when you prefer not to share your non-personal information – how to “opt out


Opting out of Interest Based Advertising (IBA) is different from opting out of cookies from as described above under the section about our “Website”.


While Maggie really enjoys receiving ads relevant to her gardening interests, if she, for some reason, chooses to stop sharing certain non-personal information for targeting advertising, she can “ opt out” of some cookie, or number, placements. If she opts out, it does not mean Maggie will stop receiving ads altogether. It only means she’ll stop receiving ads tied to her interests. Maggie has a few options on how she may opt out. One option would be to adjust her browser settings to block third party cookies. She can learn how to do this by viewing the Browser “help” menu (see more detail in our Privacy Notice Highlights above). In addition, she can go to the Digital Advertising Alliance’s, (DAA), Consumer Choice page, where Maggie will be able to opt out of allowing the companies listed to place a cookie, or number, on her device. Maggie needs to remember that if she opts out by clearing her browser cache or by resetting her cookies, she will have to take these steps from time to time to opt out again.


GroupM is an active member of the Digital Advertising Alliance and complies fully with the DAA Self-Regulatory Principles.
