III-Informed decision-making is costly. It's one of those cost factors where it's hard to put a price tag on, but the shadow costs add up. Think about some marketing campaign you are running ads for. The cost per conversion for this campaign is measured at the level of website sign-ups. The cost per conversion is at ~6 USD at the moment. Is this a good value? Using a holistic dashboard which connects marketing spend data, advertiser data, and website analytics you could find it out! Maybe the landing page which visitors reach when clicking on your ad is not optimal for your ad target audience. Maybe another ad platform you previously used is better at reaching your target persona. But you can only tell when you have all the data connected in one place. Hence, a proper data warehouse and analytics suite is needed.
