Which of the following is NOT a method to customize a prospect's score?

The correct answer is based on the context of how prospect scoring is typically customized in account engagement platforms. While adjusting baseline rules, manually modifying scores, and utilizing automation rules are all recognized methods for customizing a prospect's score, social media interactions are generally not a direct method used to alter a prospect's score.

Adjusting baseline rules involves setting foundational criteria that define how scores are applied based on certain behaviors or attributes. Manually modifying scores allows for immediate adjustments to reflect specific user interactions or changes in data. Automation rules are designed to automate the scoring process based on predefined criteria, ensuring that scores are updated dynamically in response to various triggers.

In contrast, while social media interactions can influence engagement and overall metrics, they do not serve as a standalone method for customizing scoring directly within the configuration of a prospect’s score. Thus, selecting social media interactions as the method that does not fit within the established ways to customize a prospect's score is justified.
