Growing Substack Audience as a Writer: Simple Tips to Attract More Readers

When I started trying to grow my Substack, I kept running into the same problem: I’d write something I genuinely liked… and then it would sit there with barely any new subscribers. It wasn’t that my writing was “bad.” It was more like I was asking people to care before I’d given them a reason to follow.

So I went back and rebuilt the basics—my niche, my bio, how I showed up in other people’s newsletters, and what I actually did week to week. If you’re feeling stuck right now, I get it. The steps aren’t complicated, but they do need to be specific. Here’s what I did (and what you can copy) to attract more readers to your Substack without turning your newsletter into a content factory.

Quick context: my newsletter was focused on a narrow topic, but my early posts were too broad. I was trying to “cover everything,” which usually means no one feels like it’s for them. Once I sharpened the niche and tightened my messaging, things started moving—slowly at first, then faster.

1. Define Your Niche and Write a Clear Bio

This part sounds obvious, but it’s where most people lose momentum. If your niche is “writing” or “tech” or “personal growth,” you’re not niche-ing—you’re just listing interests. I learned that the hard way.

What I recommend is choosing a niche you can describe in one sentence and repeat for 6 months. For example:

• Too broad: “Writing and productivity.”
• Better: “Weekly writing systems for busy founders (draft faster, publish consistently, build an audience).”
• Even better: “90-minute writing workflow for founders who hate marketing emails (with templates and teardown posts).”

Once you have that, your bio should do two jobs: (1) tell the right person they found their people, and (2) tell the wrong person to leave. Sounds harsh, but it actually helps growth.

Here’s a simple bio structure I used and kept coming back to:

• Who I am: 1 line about your background
• Who it’s for: 1 line about the reader
• What you’ll get: 2–3 bullets (specific outcomes)
• Cadence: “I publish every Tuesday” (or whatever you can keep)

Before: “I’m a writer and share helpful tips.”

After (what I actually switched to): “I share practical lessons on [your niche]—weekly breakdowns, templates, and what to do next when things don’t work.” Notice the difference? It’s not just what I do. It’s what the reader gets.

As for keywords: use them naturally. If someone searches “Substack growth tips,” your bio should include that phrase once or twice—but don’t turn it into a robot sentence. And yes, update it. After you publish 10–20 posts, you’ll know what themes you’re best at. Your bio should reflect that reality, not your original guess.

2. Grow Audience Through Partnerships and Collaborations

Partnerships work because they borrow trust. But they don’t work when they’re vague. The first time I tried collaborating, I sent a generic “we should collab” message. Crickets. Why? There was no hook and no clear value.

Here’s the approach that actually helped me: pick 5–10 newsletters that overlap with your reader, but aren’t direct copies of yours. Then reach out with something specific you can do in under an hour.

My outreach template (copy/paste)

Subject: Quick idea for a collab (your newsletter name)

Message:
Hey [Name] — I’ve been reading [their newsletter] and I love your post on [specific topic]. I write about [your niche] and I had an idea: would you be open to a short exchange? I can write a 250–400 word “related lesson” and you could link it in a future issue (or we can do a joint note).
No pressure—if it’s not a fit, totally okay. Either way, thanks for the great work.

What I did week to week

• Week 1: Found 12 creators (not just big ones—mid-size with active comment sections).
• Week 2: Sent 10 outreach messages using the template above.
• Week 3: Did 2 small collaborations (one guest-style note exchange + one “resource list” mention).
• Week 4: Posted a follow-up note: “What I learned from [collab topic]” and linked back to the creator.

That sequence mattered. People don’t just subscribe from the collab post—they subscribe because you follow through and keep the thread going.

Also, don’t underestimate community activity. I’m not talking about dropping “great post!” comments. I mean adding something useful: a takeaway, a question, or a short example. When you reply thoughtfully, you get noticed by both the author and the readers who are paying attention.

Substack Notes can be a real shortcut too—especially when you use them like mini teasers. I’ll write a note that says what I’m working on for my next post, then answer a question in the comments. It turns “promotion” into conversation.

One more thing: I don’t like repeating unsupported stats. If you’ve seen claims like “over 40% of subscriptions come from network effects,” I’d want a direct source before repeating it. If you want to keep this section fully credible, focus on what’s observable: recommendations, comments, and shared posts do drive discovery on Substack.

3. Engage Regularly with Your Readers and Community

Here’s what I noticed after I started replying more: subscribers didn’t just come in—they stayed. Engagement compounds.

So what does “engage regularly” look like in real life?

• Reply to comments within 24 hours. If you can do same-day, even better.
• Turn 1 reader question into 1 follow-up post. This is huge. Readers love seeing themselves reflected.
• Use Notes for quick “in-between” moments. Think: a 3–5 sentence update, a poll, or a mini teardown.
• Ask for feedback in a non-cringe way. Example: “Would you rather have this as a checklist or a short story?”

I also like doing small AMAs, but I don’t schedule them like a big event. I’ll do something like: “I’ll answer 10 questions this week—drop yours in the comments.” Then I write a single post with the best answers and link back to the questions. That turns engagement into content.

And yes, you should stay active on social platforms related to your niche. But don’t just repost your Substack link and hope. I try to share one specific insight from my post (a stat, a framework, a “here’s what I’d do differently”). Then I invite people to read the full version on Substack.

4. Create Consistent, Value-Focused Content

Consistency isn’t about posting constantly. It’s about training your readers to expect you. If you’re inconsistent, people forget you—and forgetting kills growth.

My sweet spot has been a weekly cadence with one “pillar” post and one lighter touch:

• One main post (1x/week): a deep breakdown, case study, or framework
• One note (optional, 2–3x/week): a quick update, question, or lesson learned

If weekly is too much, do biweekly. The key is that your schedule matches your energy. Don’t promise “daily” if you’ll hate your life by day 7.

How to choose what to write (so it actually attracts readers)

I use a simple filter: will this help someone do something, decide something, or understand something better? If the answer is no, I don’t publish it yet.

Here are 3 content angles that tend to perform well:

• Case studies: “I tried X for 30 days—here’s what happened.”
• Teardowns: take a real example and explain what’s working and what isn’t.
• Templates: checklists, scripts, swipe files, outlines.

Storytelling helps too, but I’ve found the best stories aren’t “I went through stuff.” They’re “I went through stuff and here’s the lesson you can use.”

Mix formats so it doesn’t feel repetitive: one article, a short note, an interview, a curated list. Variety keeps readers from getting bored while still reinforcing your niche.

And please—quality over quantity. I’d rather publish 1 solid post that gets replies than 3 rushed posts that nobody engages with.

Finally, revisit your top posts. I’ll often update older pieces by adding one new example, one “common mistake,” or a quick section answering a question I keep seeing in comments. It gives the post a second life.

5. Use Substack Features to Increase Visibility

Substack gives you tools—what matters is using them like a system, not random add-ons.

Notes: a real growth habit

I use Notes for three things:

• Tease the next post: “Working on a post about X—here’s what surprised me.”
• Ask a question: “Which approach would you pick and why?”
• Share a tiny win: a result, a lesson, a resource.

You’ll sometimes see examples like “one user got 106 followers from a single 116-character message.” I’m not going to pretend I can verify that claim without the original source, but I will say this: short Notes can absolutely spark follows when they’re specific and conversation-worthy.

If you want to test your own version, try this: write 3 Notes in a week that each do one job (tease, question, takeaway). Then check which one gets the most replies and follows.

Referral + visibility (without being spammy)

If your Substack has a referral program, use it—but keep it human. I’ll do something like: “If you know a friend who’d like this, feel free to share my newsletter.” Then I add a personal reason: “It’s helped me learn [niche] faster.” People respond to sincerity.

Tags: help the right people find you

Use tags that match what your ideal reader would search for. If you write about “personal finance,” don’t tag everything under the sun. Choose the 3–5 most accurate tags so your discovery isn’t random.

Promote outside Substack (with a better angle)

Embedding your sign-up form on your site is great, and sharing links on Twitter/LinkedIn helps. But I always include a hook in the post—something you can’t get from the headline alone.

Example: “I used this 5-step checklist for 30 days. My biggest mistake was skipping step 2. Here’s the checklist.” Then link to the Substack post.

Pin highlights where they matter

Pin a strong “start here” message or highlight your best post so new visitors don’t have to guess. If your best work is buried, you’re making it harder for people to subscribe.

6. Track Results and Adjust Your Strategies

This is where growth stops being guesswork.

Every week, I check three things in Substack analytics:

• Subscriber growth: are you gaining, holding, or bleeding?
• Engagement: comments/likes, and which posts spark replies
• Topic performance: which themes bring in the right readers

Then I ask one question: What should I do more of next week? Not “what should I change everything about?” One lever at a time.

If a post gets strong engagement, I’ll follow up with one of these:

• a short “part 2” note
• a deeper case study
• a template built from the post
• a Q&A based on the comments

Also watch timing. If your audience tends to engage more on a certain day, don’t fight it. I’ve changed posting days and seen noticeable differences just from that.

And if social sharing brings in more new subscribers than search, don’t ignore it. Double down on the platforms where your readers actually show up.

Growth on Substack isn’t just about numbers. It’s about building a community that trusts you. When you track what’s working, you can earn that trust faster.
