Question: Which of the following are benefits of reporting usage? Select three.
- Edit creatives
- Compare and optimize campaigns and ad creatives
- Measure conversions
- Understand your audience
Explanation
LinkedIn reporting helps advertisers evaluate campaign performance through Campaign Manager metrics and breakdowns. It supports comparison across campaigns and ad creatives so budgets and optimization decisions can be guided by performance data. Reporting also helps measure lower-funnel actions when Conversion Tracking is configured. Audience reporting can reveal which professional segments are engaging with ads, helping refine targeting and messaging.
Why the other options are incorrect
Edit creatives is not a reporting benefit because creative changes are campaign setup actions, not reporting usage outcomes.
