  • Understand the different metrics used across CORE


Engagements are the total number of reactions or interactions a user has with an original post. This can include retweets, replies, likes, etc. but this varies depending on the source and whether you are viewing private or public data.

You will collect the following engagements for Public data:

X - The sum of Replies + Likes + Retweets
Facebook - The sum of Comments + Likes + Shares
Instagram - The sum of Comments + Likes

Plugging in a profile will allow you to access the following engagements as Private data:

X - The sum of Replies + Likes + Retweets + Video Views + Micro Engagements
Facebook - The sum of Comments + Likes + Shares + Video Views + Micro Engagements
Instagram - The sum of Comments + Likes + Video Views + Story Tap Backs + Story Views + Micro Engagements
YouTube - The sum of Comments + Likes + Video Views

LinkedIn - The sum of Comments + Likes + Shares + Video Views

Google Analytics - The sum of Comments + Likes + Shares

Engagements per Post

This value shows you the average number of engagements a piece of content receives in the given time frame. This number is calculated as shown:

Total Engagements / Total Number of Posts = Engagements per Post

Engagement Rate

Engagement Rate helps you understand how often users engage with the Profile's content. This is shown as a percentage and is calculated using the following formula:

(Total Engagements / Total Number of Impressions) * 100 = Engagement Rate%

Growth Rate

A Brand's Growth Rate is meant to show how the Brand's following is shrinking or expanding. The Growth Rate is calculated as follows:

(Total New Followers, Page Likes, or Subscribers in a Selected Time Range) / (Total Number of Days in the Selected Time Range) = Growth Rate for Time Range

Impressions (AEI)

Impressions measure the estimated number of times people have seen your posts. This is calculated using a proprietary formula that takes into account followers, engagements, and shares depending on the data source.

Impressions per Post

This metric shows you the average number of Impressions a piece of content has generated. It's calculated using the formula below:

Total Number of Impressions / Total Number of Posts = Impressions per Post

Micro Engagement

A micro engagement is a tiny engagement where a user has clicked or opened up a post to view it in full but has not performed a full engagement. Micro engagements allow you to view interactions that are not publically visible, which is why this data is only available for Plugged In Profiles.

New Followers

The New Followers metric shows you the total number of new followers, new page likes, or new subscribers gained in a specified time range.

📝 Note: If you see a negative number of New Followers, this indicates that the Brand or Profile has lost followers in the selected time range.


This shows the total number of original pieces of content published by the Profile in the selected time range.

🚨 Important: This number does not include replies or @mentions


This metric is similar to Impressions in that it helps you understand the number of times the Profile's content has been seen. However, the Reach only counts unique individuals who have viewed the content.

Tap Back

This metric is exclusive to Instagram stories and measure the number of times a user has "tapped back" to replay a section of the story.

Total Followers

The total number of followers, page likes, or subscribers to date.


Visibility is a score that measures the popularity and impact of a piece of content. This is calculated using a proprietary formula that takes into consideration the following four factors:

  1. The format of the message (whether it's a post or a reply, contains an image, contains a link)

  2. The channel where the message has been posted (i.e. tweets have a lifespan that's shorter than a news article or a blog post)

  3. The size of the audience of the person posting that content (i.e. followers on X or monthly unique visitors for a news website)

  4. The number of people who react by engaging with the post (including comments, shares, retweets, etc.)

The Visibility score is assigned to every single post and the scores are then aggregated for each author to estimate the influence level of the author.
