Which publications should be activated as ads within your Product Ads campaigns?

Activating publications that perform better organically is the most effective strategy for Product Ads campaigns. These publications already demonstrate strong customer interest and relevance, leading to higher click-through rates and conversion potential when promoted. Leveraging existing organic success amplifies your ad performance, as the products are already validated by the market. "The set in 'stone' publications" is incorrect because static, unchanging publications may not always be the best performers; organic performance evolves. "New publications" is also incorrect because while new products can be advertised, prioritizing those with proven organic success is generally more efficient for initial campaign setup and optimization.
