An advertiser is setting up a Catalog sales campaign that will include prospecting and re targeting audiences. What is the best way to set up the re targeting audience?

Dynamic retargeting is the best approach for a Catalog sales campaign because it automatically shows users ads for products they have previously viewed or interacted with on your website or app. This personalized approach significantly increases the likelihood of conversion. Home feed retargeting is too broad and doesn't focus on specific product interactions. A Lookalike audience is used for prospecting (finding new customers similar to existing ones), not for retargeting users who have already shown interest. Search feed retargeting is not a standard Pinterest retargeting option and doesn't leverage user behavior on your catalog.
