These items are required to enable basic website functionality.
These elements are used to deliver advertisements that are more relevant to you and your interests. They can also be used to limit the number of times you see an ad and measure the effectiveness of advertising campaigns. Advertising networks usually place them with the website operator's permission.
These elements allow the site to remember choices you make (such as your username, language, or the region you're in) and provide enhanced, more personalized features. For example, a website can provide you with local weather reports or traffic news by storing data about your current location.
These elements help the website operator understand how the website works, how visitors interact with the website and whether there may be technical problems. This type of storage usually does not collect information that identifies a visitor.
