Final answer:
Share of Voice is not typically a metric generated by an Overview metrics module as it relates to market presence rather than traffic or content analytics.
Step-by-step explanation:
When referring to the metrics from an Overview metrics module, traditionally metrics such as Posts, Owly Traffic, Share of Voice, and Engagement are typically included as they are directly related to social media or website performance analysis. Followers, on the other hand, is a metric related to the audience or subscriber count of a social media account or platform, rather than traffic or content performance.
Therefore, the metric type that is not generated by the Overview metrics module from the options provided would likely be C) Share of Voice. This term often relates to the market presence of a brand or product and may require specific analytical tools and more complex data processing that are not usually part of a standard Overview metrics module which focuses on basic analytics like traffic, posts, and engagement.
