Substack’s New “Growth Sources” Feature Is Here — And It Shows Us a Lot

The dashboard just got smarter. Here’s what it means — and what’s still missing.

Substack just added one of the most important features creators have been asking for:

A Growth Sources dashboard — which just went live inside my Substack account. (Substack sometimes rolls these things out slowly, so don’t worry if you can’t see it in your dashboard yet.)

In this dashboard, you can now see where your traffic, new subscribers and paid subscribers are coming from, which recommendations are working, how Notes are driving traffic and how much of your growth is happening inside vs. outside the Substack network.

This is a major shift.

For years, creators have been working with an incomplete picture of their publication’s data — guessing where their subscribers were coming from, wondering which recommendations mattered and hoping for growth attribution tools that never came.

And now we’re seeing things organized in a single place inside the dashboard.

The dashboard is new. The questions are real.

A Huge Step Forward — One I’ve Been Waiting For

For more than a year now, I’ve been doing this kind of analysis manually for clients — pulling CSVs, interpreting patterns, mapping subscriber spikes to posts and campaigns and identifying what’s actually making a difference and where audiences are getting stuck.

I built a product around this need — the Substack Signal Scan — a PDF-based health check that helps creators interpret key performance pieces inside their publication’s performance and then match that data with wise next steps.

So yes, I’m thrilled Substack has brought this into the dashboard.

This kind of visibility is long overdue — and it validates the work so many of us have been doing behind the scenes.

If you haven’t looked at the new Growth Sources dashboard yet, here’s what it includes:

These are my own numbers — and what’s striking is how much clarity this brings around what’s working and where growth is actually happening.

But Here’s What It Still Can’t Tell You

As exciting as this update is, there are still some major gaps.

Substack tells you where your subscribers are coming from. But it still can’t tell you:

• How quickly your audience is upgrading to paid

• Which segments of your audience are more likely to upgrade (and when)

• What price point certain groups convert at more reliably

• How active your subscribers are based on how they found you

This is the kind of insight I surface for the creators I work with — going beyond top-line data to interpret how your audience behaves and what they might need from you next.

It’s not just about visibility. It’s about interpretation, context and action.

My Role in This Ecosystem

Whether through a Signal Scan or in deeper strategy partnerships, my work is about helping creators:

• Understand what their numbers really mean

• Connect those insights to audience psychology

• Design sustainable, strategic nurturing plans — without compromising their creative voice or values

Because to me and the kind of folks I work with, growth isn’t just about maximizing numbers. It’s about building momentum that connects with your life, creative goals and the audience you are nurturing a relationship with.

TL;DR

Substack’s new Growth Sources dashboard is a long-awaited upgrade — it gives you real visibility into where your audience is coming from.

But as with all data, the surface view is just the beginning.

I’m here to help you understand what your audience is doing once they arrive — which segments are most ready to upgrade, how different referral sources behave and what your numbers are actually saying about readiness, resonance and next steps.

If you’re curious about what your dashboard is telling you — or what to do with that information — I’ve opened up a few extra 1:1 Signal Sessions if you want to bring your dashboard to a live call and talk through what this data means for you.

Or add a comment to this post and tell me what you’re seeing.
