What to measure, in one paragraph
The employee advocacy metrics that matter fall into three tiers. Participation metrics — how many people post, how widely spread they are, and whether they are still posting in month three — tell you whether the program is healthy. Content metrics — shares, impressions, clicks and engagement rate — tell you whether the material is working. Outcome metrics — conversations, applicants and pipeline influence — tell you whether any of it matters to the business. Report all three, in that order, and treat a program with great reach but falling participation as a program in trouble.
The order is the point. Most programs report the middle tier only, because it produces the biggest numbers. But reach is a lagging, easily distorted signal: one enthusiastic poster can carry a month's impressions while everyone else drifts away. Participation is the leading indicator. If people keep choosing to post, the content and outcome numbers follow. If they stop, no amount of reach in the launch month will save the program.
Tier 1: participation metrics
Participation is the health check. These three numbers fit on one line of a monthly report and predict more than anything else on it.
Active advocates
The number of different people who published at least one post in the period. Not invitations sent, not sign-ups, not people who opened the material — people who posted. Track it monthly.
Breadth
Active advocates as a share of the people invited, and how they are spread across teams. A program where twelve of fifteen invited people posted is healthier than one where three people posted forty times between them, even if the second has more impressions. Breadth also shows you where the program is carried: if Sales is posting and Engineering is silent, that is a material problem, not a motivation problem.
Month-three retention
Of the people who posted in the first month, how many posted again in the third? This is the single best predictor of whether a program will still exist in a year. Launch-week participation is driven by novelty and by being asked. Month-three participation is driven by people finding it worth their time. The gap between the two is the honest measure of your program.
Set a baseline before you launch
Before the first campaign goes out, write down where you are starting from: how many employees already post about their work in a typical month, how your company page's posts usually perform, and how many applicants or inbound conversations currently mention someone's post. It takes an hour, and without it every later number is a guess about improvement. Many people already post without a program; a baseline stops you claiming credit for them.
Then set targets for participation, not reach. "Eight of the ten pilot members still posting in month three" is a target the program owner can influence through better material and fewer asks. "A million impressions" is a target that encourages chasing the most prolific poster and ignoring everyone else. If you need a reach number for a leadership slide, report it as context beside the participation figures, never instead of them.
Tier 2: content metrics
Content metrics tell you which material works and for whom. They are useful for decisions about what to share next; they are poor evidence that the program is succeeding.
| Metric | What it tells you | Watch out for |
|---|---|---|
| Shares | How many times a campaign's material was actually published by a person | Counting identical reposts as success; ten copies of one sentence is one message |
| Impressions | How many times the posts were shown in someone's feed | Concentration: check how much of the total came from one or two people |
| Clicks | Whether posts sent people somewhere — the job ad, the article, the product | Not every good post needs a link; story posts can win on comments instead |
| Engagement rate | Reactions, comments and clicks relative to impressions | Comparing across people with very different network sizes |
The most useful view of content metrics is by material, not by person. Which campaigns drew posts from many people, and which drew one? Which topics earned comments? Over a quarter, the answers tell the program owner what to look for next. A customer result with real numbers will usually beat a generic announcement; you only learn which customer results work for your audience by comparing.
Comments deserve more weight than reactions. A reaction costs a reader a second; a comment means the post started a conversation, which is closer to what the program is for. For what makes posts earn them, see employee advocacy examples by post type.
Tier 3: outcome metrics
Outcomes are what leadership actually wants to know about, and they are the hardest to measure. Be honest that attribution is partial. Then measure what you can.
- Conversations. Replies, direct messages, introductions and inbound requests that started from an employee post. Ask participants to note them in a shared sheet once a week; it takes a minute and it is the evidence most programs never collect.
- Applicants. Add a "how did you hear about us?" question to your application form, with "a post by someone who works here" as an option, and use tracked links on job posts that employees share. Recruiting is usually where advocacy shows its clearest return; we cover it in employee advocacy and employer branding.
- Pipeline influence. In your CRM, record when a prospect mentions an employee's post or when a salesperson's post started the conversation. You will not capture every case, and you should not claim the deal was caused by the post. "Influenced" is the honest word.
Pick one outcome metric that matches the program's goal and report it consistently. A recruiting program reports applicants; a sales program reports conversations and influenced opportunities. Reporting all of them dilutes attention and invites cherry-picking.
Vanity metrics to stop reporting
These numbers look impressive in a slide and tell you very little. Some are actively misleading.
- Total impressions on their own. Without breadth and retention alongside, a rising number can hide a dying program.
- "Earned media value" from industry averages. Multiply impressions by an assumed price and the figure can be as large as the assumption. If you report a value, use the method below.
- Number of registered advocates. Sign-ups measure how well you launched, not whether anyone posts.
- Content items distributed. How much material you sent out measures the program owner's effort, not the result.
- Reach multipliers. "Employees reach N times more people than the brand" claims depend on assumptions about overlap and feed behaviour that are rarely stated.
- Leaderboard rankings. They reward volume, which encourages the identical, low-effort posts that make readers tune out.
None of these are useless as raw data. The problem is reporting them as success. We go through how volume-chasing kills programs in why employee advocacy programs fail.
How to calculate employee advocacy ROI
Any ROI figure is only as good as its assumptions, so the goal is not the biggest number; it is a number that survives scrutiny. The method below compares the program's cost with what the same reach would have cost you to buy, and adds outcomes only where you can count them.
Step 1: the full cost
Add up the software, the program owner's time and the participants' time. People leave out the last one, and finance will notice. Use a loaded hourly cost and an honest estimate of minutes per post.
Step 2: the equivalent paid reach
Take the program's impressions for the period and price them at your own CPM — the cost per thousand impressions you actually pay in your LinkedIn (or other) ad account for a comparable audience. Do not use an industry average. Your CPM is a number finance can verify, and it reflects your audience and market. If you do not run paid social, skip this step and argue from outcomes instead; inventing a CPM defeats the purpose.
Be conservative about one thing: impressions from employees' networks are not the same audience you would target with ads. Some are colleagues, friends and people outside your market. Apply a discount for that — the example uses half — and say so.
Step 3: countable outcomes
Add outcomes you can count and value with your own numbers: for example, hires sourced from employee posts valued at what you would otherwise have paid a recruiter or a job board for that hire. Leave out anything you would have to guess.
A worked example (hypothetical numbers)
Every number in this example is invented for illustration. It is not a benchmark, a typical result or a Blabigo customer's figures. Replace each one with your own.
| Line | Hypothetical input | Quarterly amount |
|---|---|---|
| Software | €60 a month | €180 |
| Program owner | 3 hours a week × 13 weeks × €50 an hour | €1,950 |
| Participants | 150 posts × 30 minutes × €50 an hour | €3,750 |
| Total cost | €5,880 | |
| Impressions | 300,000 over the quarter | |
| Relevance discount | Count half as comparable to targeted ads | 150,000 |
| Your own CPM | €30 (from your ad account) | |
| Equivalent paid reach | 150,000 ÷ 1,000 × €30 | €4,500 |
| Hires attributed | 1 hire × €4,000 avoided agency or job-board cost | €4,000 |
| Total value | €8,500 |
In this invented case, the program returns roughly €1.45 for every euro spent, or about 45% ROI. Notice two things. Without the one hire, reach alone would not have covered the cost, which is common and worth saying out loud: the participants' time is the biggest line. And the result is sensitive to the CPM and the relevance discount, so show the calculation, not just the answer. A number with its workings attached is far more persuasive than a large number without them.
What this method leaves out — reputation, candidates who applied later, deals influenced but not attributed — is real. Mention it in words, not in the total.
A monthly report that fits on one page
Keep the report short enough that leadership reads it. A useful format:
- Participation. Active advocates this month, breadth (as a share of invited), month-three retention for each cohort.
- Content. The best and worst campaign by number of people who posted, with one sentence on why.
- Outcome. The one metric tied to the program's goal, with two or three named examples.
- Next month. What material is coming and what you are changing based on this month.
Quarterly, add the ROI calculation above. Monthly, it is noise. For how measurement fits into the wider 90-day plan, see how to build an employee advocacy program.
What Blabigo reports
Blabigo's employee advocacy analytics track every share made from a campaign, because each post is published by the employee from their own connected LinkedIn account and is attributed to them. It reports shares, impressions, clicks, likes, comments and engagement rate, rolled up three ways:
- Per campaign — which pieces of material landed and which quietly did nothing.
- Per team — whether one group is carrying the program while another ignores it.
- Per person — the breadth view: how many different people posted, not just the total.
That covers tiers one and two directly. Tier three — conversations, applicants and pipeline — lives in your ATS and CRM, and no advocacy tool can measure it for you honestly. Blabigo does not calculate an "earned media value" and has no leaderboard, by design. If you want to see the per-person view on your own team before deciding anything, you can run a pilot campaign in the free trial, and for how other tools approach analytics, see our employee advocacy software comparison.
