Functionize adds OpenAI marketing trackers
What changed
- Added OpenAI marketing trackers (
oaiq_cs,__oaiq_domain_probe,__obref) to monitor ad banner conversions. - Increased the number of marketing cookies from 34 to 39.
- Updated Vimeo and YouTube cookie classifications, including new bot detection and player preference trackers.
- Reclassified several OpenAI cookies from "Unclassified" to the "Marketing" category.
Why it matters
Functionize is now using OpenAI tracking tools to measure how well their ads work. This suggests they are likely increasing their spend on AI-related marketing campaigns and want better data on who is converting.
