Consent Mode v2 is now mandatory for EEA traffic in Google Ads. The documentation is dense and the CMP vendors disagree on details. Here's what actually matters.
Basic vs Advanced
Basic blocks all tags until consent. Advanced loads tags in a cookieless ping mode and uses behavioral modeling to fill the gap. Advanced recovers 30–70% of conversions for most EU clients.
