Facebook Pixel

We have installed a 'tracking pixel' that works on all of our pages to help us learn more about Facebook users' interests in the site. This information is then used to create custom audiences within Facebook to potentially allow us to create Facebook adverts targeted at members of these custom audiences. The aim is to make sure that any advertising we create is as relevant as is reasonably possible to our audience.

You can read more about the Facebook Pixel on their website and you can opt out of receiving these targeted adverts by visiting the Your Online Choices website or the Facebook advert preferences page.
