If you want to increase the effectiveness of your campaign or understand why it is not as efficient as expected, the service ‘Advertising Audit’ is what you need. Advertising audits are contract compliance audits of creative, production, and Below the Line (BTL) agencies involved in the development of advertising campaigns. Any marketing material you produce and distribute must meet advertising standards. If it doesn’t then you could get complaints about it. That’s why having an advertising audit can be useful.
