Your question is general in and so by necessity shall be my reponse. Without knowing your version of AdminStudio, I can only offer general information.
Advertisement is a property associated with the MSI 'Feature' Table. You can refer to the help for a description of the 'Feature' table and related topics on 'Advertisement'. You should also review the MSI help topic "The MSI Platform Support of Advertisement" to confirm that your destination platform will support advertisement.
In Developer, the advertisement properties are exposed through the Organization - Features view. Tuner has a similar view of the Feature properties.
