What does the bt3 cookie do?

This cookie is set by the BrightTag service on behalf of a third-party advertiser, which uses it to display targeted advertising based on user interests.

Why this cookie matters

This cookie is commonly used by signal for marketing purposes – such as tracking usage behaviour, optimising experience, or enabling marketing functionality.
