In order to assess the efficacy of a campaign or advertisement based on customer response, advertising reporting is required. This type of report is critical because it determines whether an advertisement's return on investment (ROI), which is one of the objectives of advertising, has been met. Advertising metrics and Key Performance Indicators (KPIs) are used to quantify and assess a company's attempts to influence the attitude and behavior of a target audience. Advertising KPIs now include methods for assessing the effectiveness of both traditional and digital marketing platforms. Measuring brand mentions and cost per impression (CPM) across social media channels, as well as return on investment for conventional media such as print and television, are examples of this. Examples of advertising KPIs are: impressions, ROAS, conversions, engagements, page likes, revenue, sessions etc.
