| Campaign            | Impressions | Clicks | CTR   |
| ------------------- | ----------- | ------ | ----- |
| Spring Bedding Sale | 45,000      | 1,800  | 4.00% |
| Outdoor Furniture   | 32,000      | 960    | 3.00% |
| Kitchen Appliances  | 28,000      | 560    | 2.00% |

CTR is calculated by dividing clicks by impressions and multiplying by 100. Higher CTR signals your ad copy and targeting resonate with your audience. Google uses CTR as a key factor in Quality Score, which affects ad rank and cost-per-click.
