What Really Happens When You Click “Accept Cookies” on a Website
OpenAI
When you accept cookies, your browser stores small data files that identify your device on future visits. Some cookies remember logins or shopping carts, but others track browsing habits for targeted advertising. These trackers build detailed behaviour profiles shared across sites through ad networks. Privacy laws like the UK’s GDPR require consent banners - but most users agree without realising how much data they share. Clearing or blocking cookies limits tracking but can break site features.
