What cookies are
Cookies are files created by websites you visit. By saving information about your visit, they make your online experience easier. For example, sites can keep you signed in, remember your site preferences, and give you locally relevant content.
There are 2 types of cookies:
- First-party cookies: Created by the site you visit. The site is shown in the address bar.
- Third-party cookies: Created by other sites. A site you visit can embed content from other sites, for example images, ads, and text. Any of these sites can use third-party cookies to personalize content and ads, and learn about actions you take on other sites.
Tip: Some sites may prompt you to accept or reject cookies.
There are other ways that sites can personalize content and ads. Features like ad topics and site-suggested ads in Chrome allow sites to show you personalized content. These features limit what sites and their partners can learn about you. Learn more about managing these features.
Delete all cookies

For a specific group of users, Google is testing features in Chrome that significantly limit sites from using third-party cookies to track you while browsing. If you’re part of the test group, third-party cookies are limited by default except where they are required to allow basic website services to function.
If you choose to, you can block third-party cookies completely in your settings. You can manage your third-party cookie preferences in your “Privacy and Security” settings.
