How do you measure retargeting effectiveness?

There are a number of ways to measure the effectiveness of retargeting campaigns. One way is to look at the click-through rate (CTR) of the ads. This measures how often people who see the ad click on it. A high CTR means that people are interested in the ad and are more likely to convert.

Another way to measure effectiveness is to look at the conversion rate. This measures how many people who click on the ad go on to take the desired action, such as making a purchase. A high conversion rate means that the ad is effective at getting people to take the desired action.

Finally, you can also look at the cost per conversion. This measures how much it costs to get one person to take the desired action. A low cost per conversion means that the ad is effective at driving conversions.
