Slack Metric
Collaboration
Pin Engagement Rate = Pinned Messages with Interactions in Period / Total Active Pinned Messages x 100
Pin Engagement Rate measures the proportion of pinned Slack messages that receive a reaction, reply, or click within a defined period, relative to all active pins across your channels. Slack pins are meant to surface the most important reference material in a channel, so this metric tests whether those pins are doing their job. A low rate suggests pins have gone stale or were never the right things to highlight.

A low rate suggests pins have gone stale or were never the right things to highlight.
How to calculate pin engagement rate
Why pin engagement rate matters for Slack users
Pins are one of the few persistent surfaces in Slack, where most content scrolls away within hours. When teams treat pins as a lightweight knowledge base for onboarding notes, runbooks, and key decisions, it matters whether anyone actually reads them. A high Pin Engagement Rate confirms that pinned content is current and discoverable, while a low rate signals that people have learned to ignore the pin tray.
Tracking this over time also exposes channel hygiene problems. Channels with many pins but little engagement are usually carrying outdated references that mislead new members, so the metric gives admins and channel owners a concrete prompt to prune and refresh what they keep pinned.
Understand and act on pin engagement rate with KPI Tree
Sync your Slack pin and message interaction data into your warehouse and compute Pin Engagement Rate in KPI Tree. Link it inside a metric tree to channel engagement rate and active channel ratio so you can see whether low pin engagement tracks with broader channel health or stands out as a distinct knowledge problem.
Assign RACI ownership so channel owners are accountable for the pins in their spaces, with a workspace administrator as the accountable role for the metric overall. Set a monthly review cadence in KPI Tree to revisit low-engagement pins, retire stale ones, and confirm that newly pinned content is earning attention.

Channel Engagement Rate
CollaborationMetric Definition
Channel Engagement Rate = Unique Posters in Period / Total Channel Members × 100
Channel Engagement Rate measures the level of participation within a Slack channel, calculated from the ratio of unique posters to channel members and the volume of messages, reactions, and thread replies. It distinguishes between channels that foster active discussion and those that are broadcast-only or dormant.
Active Channel Ratio
CollaborationMetric Definition
Active Channel Ratio = Channels with Messages in Period / Total Channels × 100
Active Channel Ratio measures the percentage of Slack channels that have received at least one message within a defined period. It reveals workspace sprawl - the accumulation of dormant channels that clutter search, confuse new joiners, and dilute information discoverability.
Channel Activity Analysis
CollaborationMetric Definition
Channel Activity Analysis evaluates individual Slack channels across multiple dimensions - message volume, unique contributors, thread depth, and reaction frequency - to produce a comparative view of channel health. It enables workspace administrators to rank channels by value and identify those that need intervention or archival.
Active User Rate
CollaborationMetric Definition
Active User Rate = Users with Engagement Actions in Period / Total Provisioned Users × 100
Active User Rate measures the proportion of provisioned Slack accounts that demonstrate meaningful engagement - sending messages, reacting, or participating in threads - within a defined period. Unlike simple login counts, it captures whether users are genuinely integrating Slack into their daily workflows.
