Google this month announced the introduction of behavioral modeling in realtime reports. This enables advertisers to see modeled data in realtime, filling the data gaps of users declining Analytics cookies or equivalent app identifiers.
According to Google, behavioral modeling for consent mode uses machine learning to model the behavior of users who decline analytics cookies based on the behavior of similar users who accept analytics cookies. Modeled data allows advertisers to gain useful insights from the Analytics reports while respecting your users’ privacy.
Only advertisers with consent mode enabled across all pages of your sites and/or all app screens of your apps can have behavioral modeling, and the GA property needs to collect at least 1,000 events per day with analytics_storage=’denied’ for at least 7 days.
