Dana Ditomaso discusses the importance of choosing the right metrics to measure for clients and campaigns. Key points include: - Picking the right metrics may be the most important decision that is made, as choosing the wrong metrics can lead to bad decisions. - Metrics need to align with client goals, which do not always match internal goals, so multiple reports may be needed. - When building reports, use principles of data visualization like simplifying information, comparing data over time, exploring different views of data, and being honest about performance.
