After three months of close observation, here’s what became clear. Everything we used to believe about visibility on Substack is outdated.
There’s no “growth hack,” no SEO, no discoverability trick. There’s only movement — and the system follows movement.
1. Email is over
Most new readers never open newsletters in their inbox. They read inside the app, scroll Notes, join chats, and treat Substack like a social field — not a mailing list.
That means: if you still rely on titles, subject lines, or click-rates, you’re speaking to ghosts. The real people are reading elsewhere.
2. Recommendations don’t grow you
Following “recommended writers” doesn’t bring real visibility. It fills your feed with noise — the same 50–100 voices repeating each other.
Discovery doesn’t happen through recommendations anymore. It happens when your reader talks in public — in a chat, or a comment that lives longer than the post.
3. Analytics are blind
Metrics show views, not presence. They can’t see the delayed response, the quiet echo, or the people who keep rereading without subscribing.
Substack’s analytics only catch motion that looks like traffic. They miss motion that looks like attention.
4. The real driver: sustained conversation
Chats, cross-comments, and slow replies create more movement in the network than a new essay.
One active dialogue equals a week of visibility. A silent post equals a private diary entry.
The field rewards exchange, not output.
5. The “active core” is smaller than you think — and stronger
Your publication might have 300 readers, but only 50 interact. Those 50 are your real system. They’re the ones generating visibility, because their reactions — not your posts — trigger the algorithmic pulse.
If you feed that core, the system keeps you alive. If you ignore it, the field goes still.
6. Substack in 2025 is not a platform — it’s a field of live frequencies
Readers find you by rhythm, not by tags. They join because they recognize your tone, not because of “shared interest.”
Movement is everything. Conversation is movement.
That’s the only law still working.
THE CHAT IS THE ALGORITHM
How Substack quietly replaced its feed with conversation
Everyone’s still chasing “growth.” Still posting, optimizing, wondering why recommendations don’t move the needle. Meanwhile, the real engine of Substack has shifted — and most people haven’t noticed.
The algorithm isn’t in your dashboard. It’s in the chat.
1. The illusion of reach
You can have 10,000 subscribers and still talk to the same fifty people. Analytics call it an “active core.” I call it reality. Because beyond those fifty, everything is silence — polite, measurable, and irrelevant.
For months, I tried to decode the pattern: posts with high reads, zero dialogue; recommendations that cluttered my feed but never brought real readers. Then I opened the chats.
And the field changed instantly.
2. Chat is not “community.” It’s signal.
Substack Chat isn’t a social add-on — it’s the only functioning algorithm left. Every reply, every presence ping, every thread you join creates a visible pulse in the app’s ecosystem.
A single active chat triggers more visibility than a week of new posts. Push notifications go out, new readers enter, and — here’s the secret — the system treats chat engagement as proof that your publication is “alive.”
3. Notes are echo. Chat is gravity.
Notes scatter meaning like static electricity: one spark, one scroll, gone. Chat compresses meaning into conversation. It’s slower, denser, and sticks.
Readers don’t want to be audiences anymore. They want to be witnesses — to think with someone, not after them. The chat gives them that role. And Substack’s backend rewards it.
4. What actually happens inside the metrics
When someone joins your chat, the system logs it as engagement — even if they never open your main post.
That person now becomes part of your active core. Your visibility rises. Your “read rate” stabilizes, even without new followers. Because the chat counts as “reading behavior.”
That’s the hidden loop: conversation = discovery = retention.
5. Why this matters now
Substack isn’t a publishing platform anymore. It’s an ecosystem of micro-dialogues. Text is the pretext. The chat is the transport.
You don’t “post” to be read. You enter the stream to be located — by rhythm, by tone, by recognition.
The writers who understand this are already ahead. They’ve stopped treating chat as backstage. They treat it as the main stage — where new readers actually appear, and where old ones finally speak.
6. The new logic of visibility
Here’s the math of 2025:
1 good chat = 5 posts worth of discovery
10 replies in a chat = 1 week of sustained feed presence
Comments in posts ≈ static; chats ≈ living signal
A chat with 50 people can move your publication more than a 5,000-sub newsletter
Substack doesn’t promote text. It promotes movement. And chats are where movement lives.
7. The next step
Stop chasing “content strategy.” Start building live moments.
Open one chat per week. Use a single paragraph, one question, no pressure. Let the field talk back.
That’s where the algorithm listens.
The Practice of Motion — Three Circles That Keep a Field Alive
Substack used to reward output. Now it rewards circulation — the slow, visible breathing of a field.
If you stop moving, your work disappears. But “moving” doesn’t mean producing more. It means creating loops of attention.
Here’s the practice: three circles that keep a publication alive.
1️⃣ The First Circle — The Post
The post is not the main act anymore. It’s the ignition.
Write as if you were starting a resonance, not explaining an idea. A good post now is not the one that gets read — it’s the one that makes people speak.
Structure:
One central line (the pulse)
Two paragraphs of context
One question that opens space
The post is the fire. Don’t pour water on it by “concluding.” End with a fracture, not a closure.
2️⃣ The Second Circle — The Chat
Open a chat within 24–48 hours. Use one phrase from the post — the one that vibrated the most.
This is where the algorithm wakes up. Chats are the kinetic continuation of text. They show the system that your field is breathing.
Keep it short. Ask, wait, reply, withdraw. Let others create the motion.
One active chat can keep your whole publication visible for a week.
3️⃣ The Third Circle — The Answer
The answer is what ties it back. A few days later, make a small post — not analysis, not commentary, just trace.
Example:
“From our last chat: most of you said that real discovery happens in conversation, not through posts. I think that means we’ve entered a new stage — writing as collective attention.”
This closes the loop. It tells the system — and your readers — that the field is still in motion.
The Rhythm
Repeat every 10–12 days. That’s the natural breathing of a Substack field now.
Post → Chat → Answer. Fire → Movement → Reflection.
Keep that rhythm alive, and no algorithm can bury you.

🔥 VIRAL CHAT: THE ANATOMY OF SUBSTACK MECHANICS
1️⃣ THE NAME is a hook, not a title
The chat names in the feed are displayed as push notifications.
This is the only line that a person can actually see.
💡 Formula: [Emotion / Conflict / Question] + short context
Examples:
“The system doesn’t see rhythm — discuss.”
“Чат: кто ещё чувствует, что тексты перестали работать?”
The task is to immediately give the tone and input.
People don’t know “what to talk about” — you have to set the frequency, not the topic.
💡 Structure:
One short statement.
“Substack — это больше не платформа, а поле для прослушивания”.
One line of context.
“Я заметил, что большинство моих новых читателей пришли не из постов, а из чатов”.
One question.
“Где вы на самом деле сейчас находите людей — в сообщениях, заметках или разговорах?”
📏 400-600 characters maximum.
The system likes a short first post — it shows up faster in “Active Chats”.
3️⃣ TIMING — When to open
Optimal time windows (according to the platform and user flows):
08:00-10:00 UTC — Europe / Asia Online
17:00-20:00 UTC — USA wakes up
⚡️ The most viral slot: Thursday and Sunday are the peaks of readability in the app.
4️⃣ DYNAMICS — How to hold a wave
Substack gives the chat 48 hours of “life”, after which the activity drops.
To extend:
Answer the first 3-5 lines briefly, without paragraphs.
After 12-16 hours, add a new question to the same chat.
After 36 hours, mark 1-2 comments with an emoji or quote (this returns the chat to the feed).
The goal is not growth, but the rhythm of movement.
5️⃣ INERTIA – When to close
Don’t close the chat quickly.
Leave it open for 3-5 days.
Late replies are still registered by the system as “engagement”,
and this chat will pop up in the digests of new users.
6️⃣ VIRALITY — How the system decides who to show
The “Active Chats” algorithm in the app responds to:
The first 3 responses in 30 minutes trigger the display in the general list.
More than 10 participants within 24 hours — the chat gets into “Recommended”.
If authors participate with their own audience, visibility increases.
The trick: invite 3-5 authors you are already reading to the beginning of the conversation (via @).
Their appearance will give you visibility in their field.
7️⃣ SYNTAX – How to write inside a chat
🧩 Principles:
Each replica has less than 3 lines.
Without “posts inside the chat”.
Less narrative, more reflections (“Yes, I see the same thing”, “That’s how it sounds to me”).
Rhythm > content.
The algorithm responds to frequency, not length.
8️⃣ AFTEREFFECT – How to convert to growth
When the chat is finished, don’t close it in silence.
Make a mini-post in Notes:
“Из нашего последнего чата: оказалось, что 80% новых читателей приходят из разговоров, а не из постов”.
“So I’ll keep testing it. Thank you for being my laboratory.”
→ This turns chat into content and conversation into visibility.
9 . RESONANCE – Hidden mechanics
Chat doesn’t just give subscribers,
it activates the “second wave of engagement”:
those who participated
start reading your texts more often within a week after that.
The platform considers them “returning users” and raises general metrics for you.
This is the feedback loop that used to create recommendations.
SUBSTACK CHAT’S VIRAL FORMULA (2025)
, An example of your first viral chat
Title:
“What if posts don’t matter anymore?”
The first message:
“Lately I noticed something strange — new readers don’t come from posts, or even from Notes. They come from chats. Maybe Substack quietly replaced the algorithm with us. So, tell me: when was the last time you found someone through a post — or through a conversation?”
Viral Chat in Substack — how it really works
1. The headline
This is the only thing the reader sees in the notification.
Therefore, the headline should immediately cause movement — interest or slight tension.
Formula: feeling + theme.
Examples:
“It seems that the texts have stopped working?”
“Do you also feel that the tape has become quieter?”
“Conversation as a new form of writing”
The main thing is not to describe, but to call.
2. The first message
Three short paragraphs.
One is a statement, one is an observation, one is a question.
Example:
Something is changing.
New readers come not from posts, but from chats.
Is it the same for you? Do you find people through texts or through conversations?
This is the ideal volume: 3-4 lines.
Longer, and the chat loses momentum.
3. When to open
Платформа живее всего в двух окнах:
morning
evening
The best days are Thursday and Sunday.
That’s when people log into the app more often, rather than reading from the mail.
4. How to keep moving
Substack “sees” The chat is active only while there are replies in it.
Therefore, it is important:
respond to the first 3-5 comments;
after 12 hours, add a short clarification or a new question.;
after a day, mark a couple of comments (this returns the chat to the feed).
Don’t overload it. Just a few taps are enough.
5. How long to keep the chat open
Don’t close it right away.
Optimal — 3-5 days.
Even if there is silence, the system still considers it “alive”.
6. Why do chat rooms attract new readers
Because everyone who participates in the conversation
becomes visible in the general feed of “active chats”.
If a person with their own audience writes to you
, you automatically get into the field of his subscribers.
This is the “new algorithm”:
not publications, but intersections of audiences through conversation.
7. How to write in a chat
In simple lines.
No long paragraphs.
No monologues.
This is not fasting, but breathing.
It’s better to keep it short:
“Yes, I feel it.”
“It’s the same for me.”
“What’s next?”
The system responds to frequency, not volume.
8. After the chat
When the conversation has subsided,
make a short note.:
“In the last chat, almost everyone said that new readers come not from posts, but from conversations.
It looks like this is a new form of meaning movement.”
This will fix the wave and give you another circle of visibility.
10. An example
Title:
“What if posts don’t matter anymore?”
The first message:
I notice a strange thing.
New people come not from publications, but from chats.
Maybe Substack has quietly replaced the algorithm with us?
How do you find others — through texts or conversations?
The bottom line is simple:
chat is not an add—on, but the main point of attraction.
Once a week — one short conversation.
It works better than five publications in a row.
How the chat brings new readers: a detailed diagram
1) Signals that the system considers to be “life”
The platform captures not “content”, but behavior.:
log in to the chat,
The first message,
responses, mentions, reactions,
time spent inside a conversation,
refunds (the person came to the chat again).
Each of these acts is a signal of presence. These signals raise the conversation in the visible areas of the application.
2) Points of visibility inside the application
There are several “windows” where the system can take your chat.:
The feed of “active chats” is short flashcards of current conversations.
Push notifications to subscribers of the author who created the chat (and sometimes to the authors you have subscribed to and who are already in this chat).
The tabs/digests inside the application are the “what’s being discussed” blocks.
Participants’ personal feeds — if a participant has his own audience, his participation “lights up” the chat for his subscribers (the intersection effect).
This is the “new algorithm”: the system does not try to guess “who to show the text to”, it highlights the nodes of the conversation.
3) Audience intersection — how it counts
Simplified logic (in words):
Let’s have Author A (his chat) and Participant B (he has his own audience).
When B leaves a noticeable mark on A’s chat (message/series of replies), the system writes: “B’s subscribers now have a context for A’s chat.”
In the app, subscribers of B can receive:
the card “B participates in the conversation”,
the appearance of the chat in their recommended/active conversations,
push “B wrote in the chat” (if they have the appropriate notifications enabled).
Some of B’s subscribers use this chain to enter the chat And → get to know A → subscribe to A.
This is an “audience intersection”: not a mass screening, but a bridge signal that arises from every real participation.
4) Threshold events (which “turns on” the display wider)
Observed thresholds, which often include wider illumination:
The first 3-5 responses in the first half hour — the chat gets into the “active” ones.
10+ participants in the first day — the conversation begins to flash from more distant connections.
The participation of the author(s) with their own audience multiplies visibility (their “bridges” are longer).
Returns of participants after 12-24 hours — the system understands that this is not a one-time surge, and prolongs the “life” of the chat.
Important: these are not “hard rules”, but behavioral thresholds. The bottom line is the frequency and variety of participation.
5) Chat half-life (visibility decay)
Conversations have a natural decay:
Peak visibility is the first 24-48 hours,
Then the curve drops,
adding point cues/questions can give a second ridge (another 12-24 hours).
If you close the chat too early, you cut off the tail of the “delayed” participants and their audience. The optimum is to keep the chat open for 3-5 days.
6) How does chat affect the “core” and metrics of the publication
When a new person enters the chat, the system marks them as involved with your publication.:
this increases the basic “tone” of your profile.,
Your post/notes are more likely to pop up among people associated with the chat participants.,
The “readability percentage” is stabilizing (the chat is considered “reading/interacting”, even if the posts have not yet been opened).
Then the loop is triggered: conversation → discovery → subscription → refunds → new visibility.
7) Why are chats stronger than notes and emails
Email: many people read inside the application, mail is ignored.
Short notes: unidirectional signal (like a flash, it went out).
Chat: two-way and long-lasting. It gives a lot of micro signals during its lifetime, “stitches” the audience and transfers trust.
It is easier for the reader to “enter into a conversation” than to immediately “read a long post” — the threshold is lower, and the sense of presence is higher.
8) Invisible but important mechanics
Mentions (via name/response to a remark) — increase the chance that a person will receive a push and return.
The pace of short messages (2-3 lines) accelerates the set of the first thresholds.
The variety of participants (not 1-2 people in correspondence, but 8-12 different voices) expands the display area.
Inertia: those who participated in the chat will open your next post more often (even if silently) — the system will “tweak” their display.
9) Limiters and traps
Excessive frequency: too many chats in a row — users turn off notifications, the system reduces the “weight” of your conversations.
Monologues that are too long: they turn the chat into a feed of posts, the participation rate decreases, and visibility decreases.
Private/paid chats: good for depth, but almost no intersections (visibility is limited).
Plotless chats: without a clear entry question, people do not understand what to do — they remain silent, the chat “dies” in an hour.
10) A mini example of a complete chain
You opened the chat with a simple question (3-4 lines).
In 15 minutes, 5 replies arrived → the chat was in the “active” list.
The author came in with his own audience, left 2 lines.
His followers saw the “he’s in this conversation” card, clicked, and came to you.
10-12 new members per day → the chat got into the recommended active chats.
In 3 days: +N subscriptions, an increase in returns, a stabilization of the readability percentage, new names in the comments to the next post.
No advertising, no “publication recommendations.” Only bridges of participation.
Practical checklist (in short)
A headline with a hook (feeling + theme).
First message: statement → observation → question (3-4 lines).
Two launch windows: morning and evening.
To answer the first lines, come back in 12-16 hours with another short question.
Keep the chat for 3-5 days.
At the end is a short note with a conclusion (anchors the wave).
That’s the whole mechanics.
Conversation creates intersections. Intersections provide new readers. New readers are recorded as “alive”, and they receive your next text.
Then there’s repetition, rhythm, and density.
