Here is the gap that should worry every comms team. Gallagher's State of the Sector research keeps finding the same pattern: far more internal communicators are accountable for outcomes like engagement and retention than actually measure them. The profession is judged on results it does not track. That is not a data problem. It is a choosing-the-right-data problem, and it is exactly what this guide fixes.
The stakes are real. Employees already lose close to 1.8 hours a day, almost a full working day each week, just searching for information (McKinsey, The Social Economy). And Gallup's research has repeatedly linked stronger engagement to better business outcomes, profitability included (Gallup, State of the Global Workplace). Internal communication sits at the center of both problems. If you cannot measure it, you cannot improve it, and you cannot defend its budget.
What is an internal communication metric?
An internal communication metric is a number that evaluates how well a message, campaign or channel performs with employees. It answers three questions: did the message reach its target, did people pay attention, and did it serve a company goal. A good metric is measurable, tied to an objective, and tracked over time to reveal a trend rather than a one-off snapshot.
The classic trap is mistaking activity for performance. A thousand page views tell you nothing about whether the right people read the right message. A useful metric always links data to intent: to inform, engage, align, or drive action.
Internal communication metrics vs KPIs: what is the difference?
A metric is any measurable data point, like page views or comments. A KPI is a metric tied to a strategic goal. Page views are a metric; reach among frontline employees for a safety campaign is a KPI. Every KPI is a metric, but only the metrics you attach to an objective are worth putting in front of leadership. The distinction matters because dashboards drown in metrics and starve for KPIs.
Why measuring internal communication matters more in 2026
Measurement is no longer a nice-to-have you tack on after a campaign. Gallagher's 2025 research is blunt about it: the communicators who thrive, the ones with real influence over leadership, are the ones who consistently use data to prove their value. The correlation is strong. Measurement is how internal comms earns a seat at the table.
There is also a skills shift. The same research flags data literacy as a fast-rising priority for the profession, with many teams planning to train on it this year. The direction is clear: the function is professionalizing around data. A team that still reports "we sent 40 newsletters this quarter" is speaking a language leadership stopped listening to.
The four families of KPIs to track
Instead of a flat list of twenty numbers, sort your indicators into four families. Each answers one stage of the message's journey, from delivery to real effect. Aim for one strong KPI per family before you add anything else.
1. Reach: did your message land with its audience?
This is the foundation, and it is where most teams over-trust a single number. Internal email open rates cluster around 60 to 70% depending on the benchmark (ContactMonkey and PoliteMail, 2025), and tend to run higher on smaller lists and lower on large distributed ones. Sounds healthy, until you remember Apple's Mail Privacy Protection now auto-loads images and inflates open rates, so treat open rate as a soft signal, not proof anyone read anything (Staffbase, 2025). What matters is reach against the target audience: a message seen by 90% of head office but 10% of the field has not reached its audience, however good the global number looks.
2. Engagement: did they pay attention?
Reach without attention is noise. And attention is scarce: across internal email benchmarks, only about 35% of messages are genuinely read (more than 9 seconds), while roughly 40% are skimmed in 1 to 3 seconds (Ragan and PoliteMail internal communications benchmarks, 2025). Engagement metrics get closer to the truth: read time, scroll depth, likes, comments, shares, and click-through, which averages a modest 7 to 8% internally (ContactMonkey, 2025). The contribution ratio, comparing reads to posts and reactions, reveals whether your communication stays top-down or becomes a genuine exchange.
3. Adoption: do they come back?
Adoption is the truest signal of an intranet that became a habit rather than a broadcast channel. The benchmark KPI is the active user rate: the share of employees who logged in over a week or month, against headcount. Pair it with stickiness, the ratio of daily to monthly active users, which tells you whether people dip in daily or once a month. There is no universal target here, so set your own baseline in the first quarter and steer against it.
4. Business impact: what is it for?
This is the family teams skip, and the one leadership cares about. Tie communication to a measurable outcome: onboarding completion, satisfaction or eNPS, reduction in internal email volume, program participation, even retention. This is where internal communication KPIs connect to employee engagement metrics such as eNPS, satisfaction, participation and retention, and where the function stops being a cost center and becomes a lever. Remember the Gallagher gap: far more teams are accountable for retention than actually track it. Closing that gap is where influence is won.
The internal communication metrics table
Here is a ready-to-use table: per KPI, what it measures, a realistic benchmark, and how to track it on Microsoft 365.
Use benchmarks as context, not targets. They vary widely by company size, channel, workforce type and list quality, and open-rate data has grown less reliable since Apple began auto-loading email images. Your own baseline matters more than any market average.
Example internal communication KPI dashboard
A strong dashboard shows one KPI per family on a single screen: reach by audience, read rate, active user rate, contribution ratio, and one business impact metric such as eNPS, onboarding completion or reduction in internal email. Review it monthly, but read trends quarterly to avoid overreacting to a single campaign. The test is simple: if a stakeholder cannot grasp it in thirty seconds, it holds too many numbers. A field-heavy retailer will weight reach to frontline over head office; a knowledge-worker firm will weight adoption and contribution. The families stay the same; the emphasis follows your strategy.
Build your measurement framework in four steps
You do not need a data team to start. You need a method.
- Start from the objective, not the metric. Name the business goal first (faster onboarding, safer sites, less email overload), then pick the KPI that proves it. A metric without an objective is trivia.
- Pick one KPI per family. Reach, engagement, adoption, impact. Four to start, six or seven at most. Resist the urge to track everything.
- Set a baseline. Measure your current level before you change anything. Without a before, there is no after, and no proof.
- Fix a review cadence. Monthly for the dashboard, quarterly for decisions. Communication trends need time to separate signal from a one-off spike.
Common mistakes to avoid
Four errors sink most measurement efforts. Vanity metrics: raw page-view counts flatter the report but say nothing about value; always prefer a ratio over a raw volume. Over-trusting open rates: Apple's privacy changes inflated them, so pair open rate with read rate and click-through. Too many KPIs: tracking twenty indicators means steering none. No baseline: without a starting point, you cannot prove an improvement. Fixing these four alone lifts most dashboards from decorative to decision-grade.
How to measure internal communication on SharePoint and Microsoft 365
You still need somewhere to read these numbers. If your intranet runs on SharePoint, some KPIs are already within reach: native analytics surface page views and unique visitors, inside your Microsoft 365 tenant. Dedicated tools go further with time spent, audience reach and segmented engagement. The limit of native reporting is that it is page-centric and does not show reach by audience, the one thing comms teams need most. To get to adoption, engagement by segment and impact, you need a purpose-built layer. We compared the options, native and third-party, in our guide to SharePoint analytics tools. Jint Analytics, for one, measures adoption, news and pages directly inside your tenant, with data hashed and anonymized, so you keep analytics aligned with your Microsoft 365 governance model. For the wider channel mix, see our overview of internal communication tools.
Measurement is the foundation, including for AI
Clean KPIs are not just for the monthly report. They tell you which pages nobody reads, which content is stale, which channels work, and which audiences you keep missing. That is the raw material of an intranet you improve continuously. It is also the foundation for AI: everyone wants Copilot and internal agents reading their intranet, but an agent is only as good as the information it can reach. Measure what people actually use, prune what they ignore, govern the rest, and your knowledge base becomes something an assistant can answer from. Measure first, automate next. The order is not optional.
What to remember
- An internal communication metric links data to intent; a KPI links that metric to a business goal.
- Four families structure measurement: reach, engagement, adoption, business impact.
- Benchmarks are a compass, not a verdict: roughly 60 to 70% open rate, about a third genuinely read, ~7 to 8% click-through, and set your own baseline for adoption.
- Keep to five to seven KPIs, start from the objective, and read trends quarterly.
- On SharePoint, native analytics are a floor; a dedicated tool unlocks adoption and impact by audience.
