In some cases, some performance cookies are managed for us by third parties, but we don't allow the third party to use the cookies for any purpose other than those listed below.

We use Performance cookies to do things like:

Provide statistics and analytics on how our website is used;

4. Targeting

The core purpose of targeting cookies (otherwise known as advertising cookies) is to provide BT with valuable insights into what our customers want, including but not limited to, insight into the communications and services our customers and potential customers may be interested in.

Disabling targeting cookies, generally does not stop you receiving advertising. It simply means that the advertising you receive is less likely to be aligned with your interests.

In order to gain the insights, in some instances we may analyse your personal information to create a profile of your interests and preferences so that we can contact you with information relevant to you. This helps to avoid you receiving advertising that is not relevant to you or your interests.

In some instances, we may also use this information to inform us of how well our communications are received by our customers and website users. In order to do this, we may make use of additional information about you when it is available from internal and external sources to help us do this effectively.

These cookies are also linked to services provided to BT and our customers by our trusted partners (see the Third Parties section below for more information). We/our trusted partners may also share data derived from these cookies with other members of the BT Group for the purpose and provision of the services they provide.

We use Targeting cookies to:

Link to social networks who may use information about your visit to target advertising to you on other websites;
Provide advertising agencies, our trusted partners and other members of the BT Group with information on your visit so that we can present adverts that you may be interested in, and prevent you receiving duplicate ads – see the “Online behavioural advertising” section below for further details;
Deliver content, including video content, tailored to your interests;
Help us to segment and understand our audience by providing additional information so that we can send the most relevant communications possible;
Help us identify customers similar to our audience or to serve relevant adverts to you on third party websites and apps;
Help us to understand how well our marketing initiatives are performing and whether to continue, change or cease those initiatives; and
To provide tailored communications to you and personalise your use of our website when logged in, and in limited circumstances, when logged out (subject to your preferences).

Online behavioural advertising

We, and our trusted partners (see “Third parties” section below) use information collected from targeting cookies to collect information about your device and identify your interests by understanding how you interact with our websites, communications and services. We do this so we can tailor advertising we show you on our own and third party sites and apps.

The information we and our trusted partners collect and share through targeting cookies does not directly identify you and does not include your name or address. For a small number of trusted partners we will share additional information, this is detailed in the table below.

We use your IP address, together with the interests we have assumed based on how you’ve navigated to and interacted with our websites. For example, if you look at our TV and film packages, we will assume you would like to hear about the latest TV and film offerings we, or our partners, have to offer.

We will also share interest-based advertising information with the third parties that set targeting cookies via our website.

You can opt-out of the use of targeting cookies on our website for online behavioural advertising purposes by blocking and/or deleting these cookies as described below.
