Explanation: Optimized targeting is a useful feature when creating a video action campaign as it can help reach new and relevant audiences who are more likely to convert. This feature looks beyond manually selected audience segments to find new audiences that may have been missed, improving the performance of the campaign. Advertisers should use optimized targeting if they want to acquire new customers, increase conversions without increasing bids or cost per customer, or identify new people who perform well for the campaign. Optimized targeting is automatically turned on for all campaigns, but can be turned off in the ad group settings. Additionally, criteria such as audience segments or keywords can be added to the optimized targeting, which will use these signals to find similar criteria to serve ads on.
