Which metrics are tracked in the Google+ Post Engagement Report?

The Google+ Post Engagement Report specifically tracks metrics that provide insight into how users interact with posts. The correct answer includes +1s, Reshares, Comments, and Link Clicks, which are critical for understanding the overall engagement level of a post.

+1s indicate the number of users who appreciated the content, similar to a "like" on other platforms. Reshares show how much the content is resonating with users by measuring how many times it has been shared within their networks, which can significantly amplify reach. Comments reflect direct engagement and user opinions, offering qualitative insights into audience sentiment. Finally, Link Clicks measure how effective the post is in driving traffic to links shared within the content, showcasing the actionable outcomes of engagements.

The other options do not encompass the complete range of interactive metrics that Google+ aims to provide for assessing post performance. For example, while Likes, Shares, and Comments were popular engagement measures, they don't specifically capture the unique functions of Google+, particularly the concept of +1s and Reshares that are specific to that platform's engagement framework. Similarly, the options that include Impressions or Favorites don't accurately reflect the comprehensive engagement metrics that Google+ emphasizes in its reports.
