Substack’s Algorithm Just Changed — And You’re Probably Already Ahead of It
Substack’s new model confirms the future of publishing belongs to creative momentum and reader trust
Curious about your own Substack data? Check out SubSight, a tool I built to help you see the connection between your data, your voice and your audience.
A few weeks ago, Substack’s Head of Data, Mike Cohen, quietly published a technical deep-dive on how their recommendation system now works.
It could’ve flown under the radar — a bunch of graphs, model names and language that most creators might skip. But buried in it was something that lit up my creative radar:
Substack just rebuilt their recommendation architecture to reward the exact kind of publishing you’re already doing — if you’ve been following your creative momentum and resisting rigid formulas.
I didn’t find proof of this shift because I was trying to outsmart the algorithm. I stumbled into it by doing what I always do: writing what felt most urgent, in the order that made the most sense, during a creative window that felt alive. And for the first time in a long time, the platform responded like it was designed to amplify that flow — not fight it.
What Changed — And Why It Matters
Substack’s new model is built on something called sequential modeling.
Here’s what that means in plain language:
Old algorithm: looked at your reader like a static profile.
New algorithm: looks at what journey your reader is on — right now.
Instead of asking, “What does this person usually like?” the system now asks,
“What would be the natural next step for this reader in this moment?”
It’s not just about a single post performing well in isolation. It’s about a publication creating momentum — pieces that build on each other, follow a rhythm and invite the reader into a connected experience.
This shift is subtle but huge. And it aligns with something I’ve always believed:
Publishing is about growing relationships, not one-off punches of content.
How Substack’s Model Is Philosophically Different
Most platforms demand optimization.
TikTok wants a hook in the first 0.8 seconds.
Instagram wants you posting at 11:43 AM on Tuesdays.
The algorithms are visible, demanding and exploitative by design.
But Substack’s incentives are different. Because they make money through subscriptions — not ads — they don’t need to trap readers in infinite scroll. They want people to find writing (or podcasts or videos) they genuinely connect with and choose to support over time.
That means the algorithm’s job isn’t to generate endless engagement. It’s to match subscribers with work they value — the kind of work that builds trust, resonance and longevity.
In short? I don’t think Substack is trying to hack your brain. They’re trying to anticipate and mimic your natural curiosity.
Why This Validates the Framework We’ve Been Using All Along
If you’ve been publishing with creative intelligence — following momentum, building thematic arcs, honoring your natural flow — then this is the moment where everything clicks into place.
This is the framework I laid out in The Substack Publishing Reset earlier this year:
Monthly themes
Intentional arcs
Format follows function
Flow mapping
Building an evergreen library
None of this was ever about gaming a system. It was about designing a publishing practice that felt human, sustainable and true to how creativity actually works.
And now? That’s exactly what Substack’s new system is designed to amplify.
You’ve been ahead of the curve — even if you didn’t know it.
How I Discovered the Shift (By Accident or Instinct?)
Here’s the funny part of today’s post where I admit to you that I didn’t figure any of this out by reading a white paper.
I figured it out because I broke my own schedule and published four short daily posts in a row — something I never do and that I, honestly, felt a bit squeamish about. Each post was connected, each one exploring a different facet of the emotional context inside running a Substack publication.
Saturday’s post caught momentum, and that surprised me.
Saturdays aren’t usually high-traffic days. But something told me to hit publish — and when I saw the spike, I started tracking the pattern.
Then I re-read the technical breakdown of Substack’s new system… and everything clicked.
I hadn’t gotten lucky.
I’d been following the exact creative publishing framework I advocate for. And now, the platform architecture was built to recognize and reward it.
That’s when I knew: something important had changed.
This Should Make Publishing Easier, Not Harder
Of course, I can hear you already: “Greeeeeeeat, another algorithm to optimize for.”
But I really don’t think that’s what’s happening here. This isn’t a new hoop to jump through — it’s confirmation that the way you’ve already been publishing can now work with the system, not against it.
If you’ve felt torn between what you want to write and what you should write for the algorithm?
Here’s your permission slip:
Write the weird and wonky posts that only you can publish. And follow your curiosity for as long as it goes. Build it into a connected journey. That’s what this model is built to reward.
You don’t need to batch endlessly. You don’t need to rotate topics for the sake of variety. You don’t need to force a voice that’s not yours.
You just need to trust your rhythm.
When something feels alive creatively, lean into it. Publish in waves. Follow momentum. Build connection.
That’s how good publishing works. And finally, the platform agrees.
What This Means for Your 2026 Strategy
Substack’s evolution makes a few things very clear. Here’s what I’m exploring in tomorrow’s post:
Think in waves, not isolated posts
Plan in thematic arcs, not scattered content calendars
Follow your momentum, and publish accordingly
Respond faster to resonance — the window for lift is shorter than it used to be
In tomorrow’s paid post, I’ll explore how you can make these shifts inside your real calendar — without burning out, breaking your voice or collapsing from boredom (because publishing for algorithms is b-o-r-i-n-g).
This Isn’t Just a Trend — It’s a Return to What Works
If you’ve been reading my work for a while and digging into your own publishing flow and creative curiosity, you’ve probably already felt this shift — in your writing, your energy and your relationship with readers. Now we have some algorithmic framing from Substack to back it up.
Good publishing is about rhythm, relationship and resonance.
Good algorithms just get out of the way.
Substack’s shift doesn’t mean you have to change everything. It means you get to trust what’s been working — and scale it intentionally.

New to Amanda and The Publishing Spectrum? Here’s how other leading publications work with me (inside a monthly editorial partnership):
I work with a small number of Substack publications each month inside a $499+/mo managing-editor container. You get one call plus one deep deliverable (choose: a developmental edit of one essay or a dashboard/KPI read + action plan).

I love the way this feels. Thank you so much for sharing this update and your insights about it.
I recently read a book called The Correspondent by Virginia Evans. It’s an epistolary novel that Ann Patchett (goddess that she is) called “a cause for celebration.” I bring it up because the experience of reading it made me long to indulge in the natural rhythm and intimate connection of old-fashioned letter writing.
And I found myself thinking about the ways in which a “newsletter” might be more like an actual letter. It feels painfully obvious (I’m almost embarrassed to share it here), but that realization is making me rethink the way I come to my Substack writing. Again. 😆
Happily, what you have shared here seems to encourage what I’m leaning into, so that makes me happy. 💜
Beautiful information, Amanda, and encouraging, thank you! I feel like I'm doing a lot of the things you recommend, although the monthly theme is something I don't really pursue in my writing at The Next Write Thing, but will be using (in a way) for a new project I'm about to launch. You know what I'm referring to. If you get a chance, head on over there, and take a look at the progress. I'd love some feedback and will reach out to you later. Big hug! xo
