What are the Methods of evaluating an ad campaign?

There are several methods for evaluating an ad campaign, including measuring brand awareness, brand recall, and brand recognition through surveys and focus groups. Analyzing key performance indicators (KPIs) such as click-through rates, conversion rates, and return on investment (ROI) can also provide valuable insights. Additionally, conducting A/B testing to compare different versions of the ad can help determine which elements are most effective in driving desired outcomes.
