Which metric is commonly used to assess the performance of a Google Ads campaign?

Click-Through Rate (CTR) is a key metric used to assess the performance of a Google Ads campaign because it measures how often people click on an ad after seeing it. This ratio of clicks to impressions indicates the effectiveness of the ad in attracting attention and engaging potential customers. A higher CTR suggests that the ad is relevant and appealing to the audience, which can lead to better overall performance of the campaign. Advertisers often use CTR to gauge interest in their products or services and optimize their ad copy and targeting strategies to improve engagement.

The other metrics, while important, serve different purposes in evaluating a campaign's performance. Return on Investment (ROI) focuses on the overall profitability of the campaign, encompassing costs and revenues rather than engagement. Cost per Click (CPC) measures the amount spent for each click, which is useful for budget management but does not directly assess ad effectiveness. Impressions indicate how many times the ad has been displayed but do not reflect user interaction or engagement levels. Thus, CTR stands out as a direct indicator of an ad's success in generating interest through clicks.
