The data comes from an extensive range of sources across the market. Primarily this is data collected by either TrinityP3 or one of our colleagues and sorted and collated into the database. The data is anonymous in the database with information on the size and type of client and the size and type of agency recorded.
The data is entered into the database on a regular basis to ensure the data within the database is comprehensive, extensive and relevant. While the number of data points against any cost centre will vary, there is always a statistically significant sample size in the database.
The data also comes from those using Ad Cost Checker. The data entered into the database by those using the system is also included in the database, but only after been checked that it sits within the statistically accepted range. Any spurious data entered is flagged and checked by TrinityP3 staff to ensure no false of dubious data is entered into the database.
This data is also not recorded in any identifiable way, except against the same criteria as the rest of the data in the database being the size and type of agency and the size and type of advertiser.
All data is date stamped and is retired from the active database 12 months after it is entered to ensure that the data remains current and relevant.
