The useful bits
- Use the explanation when investigating a discrepancy between the consent state the team expects and the behaviour of a tag. Compare the consent-management platform, default and update commands, tag timing and the resulting request rather than diagnosing the whole setup from one parameter.
- This is an implementation reference, not legal advice or a new Google consent requirement. The article explains technical behaviour; it does not verify that a particular site has collected valid consent.

David Vallejo explains how Google Consent Mode resolves consent signals and encodes them in the gcd parameter. The article is a technical troubleshooting reference for the person implementing measurement, rather than a new consent policy. It can help investigate why a tag behaves differently from the setting a team expected.
