What does the Private Graph identity stitching option do when creating a new merge policy?

The Private Graph identity stitching option is designed to enhance customer segmentation by merging related identities into one cohesive profile. This process is crucial for marketers who aim to create more personalized and targeted campaigns. By incorporating various identifiers (like email addresses, device IDs, or cookies) associated with a single individual into one unified profile, businesses can gain a holistic understanding of their customers' behavior and preferences. This comprehension ultimately leads to improved accuracy in audience segmentation, allowing for more relevant marketing strategies.

In contrast, options suggesting the separation of identities or preventing profile merging do not align with the objective of the Private Graph feature, which is focused on consolidating identities for richer insights. The ability to merge identities offers a strategic advantage in developing a deeper connection with customers, making it possible to tailor marketing efforts effectively.
