When creating custom reports in Pinterest Analytics, what advanced segmentation technique can be used to isolate the performance of specific ad creatives within a larger campaign?

When creating custom reports in Pinterest Analytics, the advanced segmentation technique used to isolate the performance of specific ad creatives within a larger campaign is filtering by 'Pin name' or 'Pin ID'. Each ad creative on Pinterest is associated with a unique Pin name and Pin ID. By applying a filter based on these identifiers within the custom report, you can isolate the data for that specific creative and analyze its performance metrics such as impressions, clicks, saves, and conversions. This allows for a detailed comparison of different ad creatives within the same campaign, identifying which are most effective at driving the desired results. This granular level of analysis is crucial for optimizing ad creatives and improving overall campaign performance. For instance, if a campaign contains multiple variations of an ad promoting a specific product, filtering by 'Pin name' allows you to directly compare the performance of each variation and identify the top-performing creative.
