What key performance indicators (KPIs) should be prioritized when evaluating the success of a brand awareness campaign compared to a direct response campaign on Yahoo! Japan?

When evaluating campaign success on Yahoo! Japan, brand awareness and direct response campaigns require different key performance indicators (KPIs). For brand awareness campaigns, which aim to increase brand recognition and positive perception, prioritize reach, impressions, frequency, and brand lift. Reach measures the unique number of users exposed to the ad. Impressions track the total number of times the ad was displayed. Frequency measures the average number of times a user saw the ad. Brand lift surveys track changes in brand awareness, perception, and recall. Direct response campaigns, which aim to drive immediate action like sales or leads, prioritize click-through rate (CTR), conversion rate, cost per acquisition (CPA), and return on ad spend (ROAS). CTR measures the percentage of users who clicked on the ad. Conversion rate measures the percentage of users who completed the desired action (e.g., purchase). CPA tracks the cost of acquiring one customer. ROAS measures the revenue generated for every dollar spent on advertising. For example, a brand awareness campaign for a new beverage would focus on maximizing impressions and reach to get the brand in front of as many people as possible, while a direct response campaign for an e-commerce store would focus on maximizing conversions and ROAS to drive sales. Measuring clicks is less important for brand awareness, while measuring brand perception is less important for direct response. It is crucial to focus on appropriate KPIs, as incorrect measurement leads to flawed strategic decisions.
