Hello, I am enquiring about digital advertising services in London and want to track [clicks / forms / calls / orders or other actions]. Please define each event, where it is recorded and how repeated actions are handled. How are enquiries distinguished from completed sales? What attribution window and data sources are used, and which actions cannot be tracked? Can you demonstrate with an example containing no personal information and list advertising spend and service fees separately? This enquiry only checks reporting definitions; no campaign is authorised and no guaranteed results are requested.
