Requirements Clarification & Assessment

Objective:

  • To optimize ad revenue by aligning advertisements effectively with users.

Key Metrics:

  • Click-Through Rate (CTR): Measures the percentage of users who click on an advertisement out of the total who view it. It is an indicator of how well the ad captures user interest.
  • Conversion Rate: Measures the percentage of users who complete a desired action (e.g., purchase) after clicking on an ad. It reflects the ad's effectiveness in driving revenue.

Assumptions:

  • The advertising agency has control over ad placements and targeting but not over the product or service being sold.
  • External factors influencing conversion (e.g., product quality, pricing) are beyond the agency's control.
  • Historical data on user interactions with ads, including clicks and conversions, is available for analysis.

Data Requirements:

  • User demographic and behavioral data.
  • Historical ad performance data (impressions, clicks, conversions).
  • Product and ad metadata (e.g., category, type, reviews).

Constraints:

  • Limited ability to influence the conversion process beyond user engagement with the ad.
  • Need for real-time or near-real-time decision-making to optimize ad placements.
