Privacy

The use of online advertising has implications on the privacy and anonymity of users. If an advertising company has placed banners in two Web sites. Hosting the banner images on its servers and using third-party cookies, the advertising company is able to track the browsing of users across these two sites.

Third-party cookies can be blocked by most browsers to increase privacy and reduce tracking by advertising and tracking companies without negatively affecting the user's Web experience. Many advertising operators have an opt-out option to behavioural advertising, with a generic cookie in the browser stopping behavioural advertising.
