If you use Google Ads, there are several metrics to help you determine if a PPC campaign is a success. One of the most useful is your conversion rate, which tells you how many people completed a desired action versus how many people interacted with your ads. A high conversion rate indicates a significant number of people are taking action after they click your PPC ads and visit your website. You can also use these metrics to assess your digital marketing efforts: Clickthrough rate: CTR tells you what percentage of the people who saw your ad went ahead and clicked it. To achieve a high CTR, make sure your ad keywords match the user's intent. Otherwise, you won't attract as many clicks as you'd like. Return on ad spend: To calculate return on ad spend (ROAS), divide the amount of money you spend on PPC ads by the amount of money you make from pay-per-click advertising. The higher your ROAS, the better. Although it's helpful to know your ROAS, this isn't the best Google Ads metric, as you may have trouble determining if revenue comes from your PPC ads or other digital marketing efforts. Cost per click: CPC is one of the easiest metrics to calculate. Simply add up how much you spent on ad clicks and divide by the number of clicks you received. For example, if you spent $2,100 to get 800 clicks, your CPC is just over $2.62. To keep the cost of your PPC ads as low as possible, make sure you optimize each campaign. Cost per conversion/cost per acquisition: If you want to monitor the performance of a single PPC campaign, make sure you know your cost per conversion or cost per acquisition. This is how much you spend on each desired action, such as email sign-ups, form submissions, or website purchases.
