Answer:
Step-by-step explanation:
If the objective of a campaign is to get as many new users as possible at a certain cost, two metrics that might be most important to review are:
Cost per Acquisition (CPA): This metric measures the cost of acquiring a new user through the campaign. To achieve the objective of getting as many new users as possible, the CPA should be as low as possible. The lower the CPA, the more cost-effective the campaign is in acquiring new users.
Conversion rate: This metric measures the percentage of users who take a desired action (e.g., sign up, purchase, download) out of the total number of users who were exposed to the campaign. A high conversion rate indicates that the campaign is effectively convincing users to take the desired action. Therefore, it would be important to keep an eye on the conversion rate of the campaign to make sure it's high enough to reach the objective.
Both metrics are essential to evaluate the performance of the campaign, CPA will give us an idea of the cost of the campaign and conversion rate will give us an idea of how well the campaign is doing in terms of getting new users.
