Our advertising and measurement cookies
To help our partners manage their advertising and websites, we offer many products, including AdSense, Google Ads, Google Analytics, and a range of products within the Google Marketing Platform. When users visit a page or see an ad that uses one of these products, either on Google services or on other sites and apps, various cookies may be sent to their browser.
These may be set from a few different domains, including google.com, doubleclick.net, googlesyndication.com, or googleadservices.com, or the domain of our partners’ sites. Some of our advertising and measurement products enable our partners to use other services in conjunction with ours (like an ad measurement and reporting service), and these services may send their own cookies to your browser. These cookies will be set from their domains.
The cookie information on this site is made available to assist with the use of Google’s ad products and reflects cookies that can be associated with these products and may be sent to a user’s browser. Cookie purposes reflect the range of products and features supported in our ad products, but individual cookies may rely on only a subset of purposes, depending on implementation of the product. Although the cookies listed here are those associated with our advertising and measurement products, you can find more details at How Google Uses Cookies.
Purpose descriptions:
Functionality - Cookies used for functionality allow users to interact with a service or site to access features that are fundamental to that service. Things considered fundamental to the service include preferences like the user’s choice of language, product optimizations that help maintain and improve a service, and maintaining information relating to a user’s session, such as the content of a shopping cart.
Security - Cookies used for security authenticate users, prevent fraud, and protect users as they interact with a service.
Analytics - Cookies used for analytics help collect data that allows services to understand how users interact with a particular service. These insights allow services both to improve content and to build better features that improve the user’s experience.
Advertising - Google uses cookies for advertising, including serving and rendering ads, personalizing ads (depending on your ad settings at g.co/adsettings), limiting the number of times an ad is shown to a user, muting ads you have chosen to stop seeing, and measuring the effectiveness of ads.
