What is a Cookie?
A cookie is a small amount of data, which often includes a unique identifier that is sent to your computer or mobile phone browser from a website and is stored on your device.
Each website can send its own cookie to your browser if your browser’s preferences allow it, which the site can then access when you visit it again to track online traffic flows, for example.
Why are Cookies used?
Cookies do lots of different jobs, such as:
- Remembering what items a user may have added to a shopping basket or an itinerary as the user moves between pages on a website
- Saving a user's preferences to allow them to customise a website
- Measuring what users do on a website to ascertain which parts of a website are popular, how long they spend on a website, how often users return, where they come from etc
Cookies are set by this website (first party cookies) but may also be set by other websites (e.g. YouTube) that run content on the website’s pages (third party cookies).
Cookies can be set to remember a visitor for the duration of their visit (session cookies) or to remember a visitor for repeat visits (persistent cookies).
- Keep track of whether you are logged in or out of the website
- Anonymously measure how you interact with the website through Google Analytics
- Enable the function of some forms through Dotmailer’s survey tool
- Allow you to share pages with social networks such as Facebook
