OpenAI's Ad Pixel Tracks by Default, and European Shops Aren't Switching It Off
OpenAI's ChatGPT ad pixel ships with tracking switched on; a site has to add a line of code to hold it back until a visitor consents. We loaded 341 shops running it, most of them European: 224 send a measurement event to OpenAI before any consent, 95 while a cookie banner is on screen. We tested the SDK: the consent control works, the default is just left on.
