What is the difference between necessary and non-necessary cookies on your website?

Necessary cookies are the ones your website needs to work – for example to keep visitors logged in or save a shopping basket – and they’re placed automatically. Non-necessary cookies, such as analytics and advertising trackers, may only be placed on a visitor’s device if they’ve given consent.

Cookies are small data files sent from a website’s server to your browser and stored on your device. Their purpose varies, but they’re often used to:

  • Personalise a website
  • Help visitors navigate a website
  • Improve the user experience
  • Store visitors’ preferences and login details

Necessary cookies

Necessary cookies are placed automatically on your computer or device when you visit a website or take certain actions on it. They’re only used to transfer data online and are strictly necessary for the website to work. Examples include:

  • Session cookies that keep users logged in as they navigate the site
  • Persistent cookies that save users’ custom settings
  • Cookies that keep a shopping basket saved during checkout

Non-necessary cookies

These are all other types of cookies that don’t fall under the definition of necessary cookies. Non-necessary cookies and similar technologies are only placed on a user’s device if the user has consented. Examples include:

  • Cookies from analytics tools such as Google Analytics
  • Advertising trackers such as the Facebook Pixel
  • Cookies from third-party widgets or embedded content

Some data protection laws, such as the GDPR, may require you as a site owner to tell your visitors about cookies and ask for their consent to use them. You can do this in Loopia Sitebuilder by turning on the cookie consent banner or connecting CookieBot.
