Cookies and other technologies
What are cookies and how do they work?
Cookies are small bits of text that are downloaded to your computer or other device when you visit a website. Your browser sends these cookies back to the website every time you visit the site again, so it can recognise you and can then tailor what you see on the screen.
Pixel tags (sometimes called web beacons): A pixel tag is an invisible image with a line of code which is placed within an email message or on a web page.
We have summarised the cookie types into the following three categories:
1. To provide you with the service you have asked for
For example, keeping you logged in during your visit. Without cookies the site might forget you and you'd have to constantly log back in. When you buy products, cookies make sure they're still in your shopping basket when you get to the checkout. These cookies are sometimes called essential cookies and are necessary to provide you with the services or products you have requested.
2. To provide you with adverts that are more relevant to your interests
3. To analyse and improve your browsing and email experience
For example, for analysis purposes, we like to know what pages and links are popular, including the information in our emails, and which ones don't get used so much to help us keep our sites and emails relevant and up to date. We also use them to customise your visits to the site, for example to remember the choices you make such as your language or region.
How to manage cookies
Most browsers will enable you to manage your cookies preferences e.g. have the browser notify you when you receive a new cookie or use it to disable cookies altogether. If you do decide to disable or delete them altogether some sites won't work as well as they rely on cookies to provide you with the service you have requested.
