If you choose to turn off online behavioural advertising it does not mean you will no longer receive advertising on the internet. However, it does means that the display advertising you see on websites may not be tailored to your likely interests or preferences on the web browser you are currently using. Using this tool only applies to online behavioural advertising and will not affect other services that use the same technology, called cookies, such as email, shopping basket preferences and photo hosting. Web sites that you visit may also still collect information / use cookies for other purposes.
You can also manage cookies in the privacy settings on the web browser you are using. Please see our top tips sections sections to show you how to do this. However, deleting browser cookies can remove the preferences you have made using this site, so you should visit this page periodically to review your preferences.
