Small files a site stores in the visitor's browser to remember settings or the cart, or for analytics and advertising.
Types
Necessary cookies (for example cart, login), analytics cookies (for example Google Analytics) and marketing cookies (for example Meta Pixel, Google Ads).
What the law says
In Europe (GDPR and ePrivacy), only necessary cookies are allowed without consent. The rest switch on after the visitor accepts them, with a clear option to refuse.
In practice
A proper cookie banner, connected to your analytics tools so they do not load before consent.
