How to Visualize ERG Data for Free (No Software Required)


A step-by-step walkthrough for turning the ERG data you already collect into a dashboard leadership will actually read — using $0 in software.

Most ERG program managers think the reason their data story is weak is that they don't have the right software. They're wrong. The reason it's weak is that the data isn't standardized. This post is the direct answer to how to visualize ERG data for free, pulled from the video above.
The 4-step order of operations
1. Pick the 5 metrics that actually matter
Don't try to track everything. Track these five, consistently:
- Active members per ERG (logged in last 90 days)
- Events held per quarter
- Average event attendance
- % of ERG leaders still active vs. start of quarter (retention)
- One business-tied outcome (referrals, retention, product input — pick one per ERG)
This is the measurement layer of your ERG operating system. Without it, every quarterly review feels like starting from scratch.
2. Put every ERG on the same template
One spreadsheet. One row per ERG per quarter. Same columns. This is non-negotiable — if every ERG reports differently, no dashboard can fix it. Use your ERG blueprint as the source of truth for what each ERG is supposed to be measuring against.
3. Build 3 charts, not 30
The video covers exactly which three:
- Membership trend — line chart, one line per ERG, by quarter.
- Engagement ratio — bar chart, active members ÷ total members, per ERG.
- Business outcome contribution — table or simple bar, the one tied metric per ERG.
That's the whole dashboard. Three charts on one page. Free, in Google Sheets or Excel.
4. Ship it on a cadence, not on demand
The dashboard's power isn't the visualization — it's the fact that it shows up every quarter, unprompted, in the same format. That's how you stop being the bottleneck in your own ERG program.
Why this beats buying software (for now)
Software solves a data collection problem. Most ERG programs have a data definition problem. Until your 3Ps and MVQ are written down for every ERG (see the 3Ps of ERGs), no platform will save you — it'll just produce prettier versions of the same noise.
Once your definitions are tight and your spreadsheet works, then a platform is worth it. Not before.
