Consider the following scenarios and decide if each demonstrates an effective approach to bidding within ad sets:
- Scenario 1: A campaign for a seasonal fashion line uses a cost-per-impression (CPM) bidding strategy across all ad sets, regardless of the varying competition for different fashion categories.
- Scenario 2: An ad set for a new coffee brand uses a cost-per-click (CPC) bidding strategy to drive traffic to its website, with bids based on competitive keyword analysis.
- Scenario 3: An online course provider uses automated bidding for its ad sets targeting different educational segments, allowing the platform to adjust bids for optimal results.
- Scenario 4: A tech gadget campaign uses manual bidding and frequently adjusts bids throughout the day based on real-time ad performance data.
Identify which scenarios represent effective use of bidding strategies in ad sets.
