Ad delivery and recommendations, including from off-Meta activity

Meta uses cookies to help show ads and to make recommendations for businesses and organisations to people who may be interested in what they promote. Examples: helping deliver ads to people who previously visited a business's website, purchased its products or used its apps, and recommending products and services based on that activity; and limiting how many times you see the same ad. The 'fr' cookie is used to deliver, measure and improve the relevancy of ads, with a lifespan of 90 days. Cookies are placed and read on other companies' sites and apps that use the Meta Products, without further action from you, whether or not you have an account or are logged in. For people with a Facebook account, Meta also uses data advertisers and partners provide about their activity off Meta Company Products to show better ads, and says they can control whether that data is used for ads in their ad settings.

For example, the "fr" cookie is used to deliver, measure and improve the relevancy of ads, with a lifespan of 90 days.

Ad measurement and the _fbp cookie

The '_fbp' cookie identifies browsers for providing advertising and site analytics services and has a lifespan of 90 days. Business partners may also share information with Meta from cookies set in their own websites' domains, and cookies named _fbc or _fbp may be set on the partner's domain.
