Answer Example

I use metrics like CPM (Cost Per Thousand Impressions) to measure cost efficiency, CTR (Click-Through Rate) to evaluate engagement, and ROAS (Return on Ad Spend) to assess overall profitability. For instance, I identified underperforming placements in a campaign by analyzing CTR and shifted budget to higher-performing channels, which improved ROAS by 20%.
