Scroll Substack Notes for thirty seconds and you’ll find one. “Drop your link and I’ll read it.” “Under 500 subscribers? Post your stuff below.” Hundreds of comments, hundreds of links, and everyone waiting for someone else to read theirs.
These threads can pay off big for whoever starts them. For the people replying, the payoff is much less clear, and a bare link is the weakest move you can make. Reply with one specific sentence, comment on other writers’ work, and post your own human notes without a link. Here’s the data, then exactly what to do.
The one documented win I found went to the person who posted the thread
Writer Alesia Zakharova tracked her early Notes and published the numbers. At 96 subscribers she posted a “drop your link below” note. It drew 11,537 impressions, 231 likes, 397 comments, and 79 new subscribers in two days. She went from 96 to 175.
A month earlier she’d posted a nearly identical note and got 41 likes, 36 comments, and 3 new subscribers. Same format, wildly different result. Her explanation is the month in between: two to three notes a day, photos, real engagement with other new writers, and a weekly post. The thread worked because the ground was prepared, not because the note was clever. She sells a Notes playbook, so weigh her advice accordingly, but the numbers are hers and they’re specific.
Here’s what I couldn’t find: anyone who has published what those 397 commenters got. The data on the person who starts the thread exists. The data on the person who replies doesn’t.
Likes and comments are not subscribers
Subscriber counts are private on Substack, so the best public data comes from analytics tools that authors have connected. It isn’t Substack’s own data and it isn’t perfect, but the patterns agree with each other.
One analysis of 243,483 Notes from November 2025 through April 2026 looked at the most-liked 8.2%: 20,066 Notes that cleared 46 likes. Forty percent of them earned zero subscribers. A separate look at 35,845 Notes from May 2026 found that below 100 likes, roughly one Note in two converted nobody. Above 250 likes, only one in ten did.
So a 400-comment thread feels like traction. Whether it is depends on who’s reading, and in a link thread most of the people reading are busy posting their own.
The link itself costs you reach
An analysis of roughly 655,000 Notes from July 2026 found that adding a link cut median likes from 4 to 2 and doubled the share of Notes with zero likes, from 14.6% to 29.0%. Short notes with a link fared worst: 40.7% of the ones under 150 characters got no likes at all.
Where the link points matters too. Among 29,993 Notes from 657 authors with analytics attached, a link to a Substack converted 6.56 subscribers per 100 likes, against 2.22 for Notes with no link. A link to any other site produced 0.147 subscribers per Note, and 92.4% of those Notes produced none.
The takeaway: link only to your own Substack, and only when the note has something to say. Even then, a Substack link lands about 7% behind a link-free Note on subscribers per Note, because it reaches fewer people. A link isn’t a growth lever. It’s something you spend.
What to do when you see a drop-your-link thread
Four moves, in the order I’d use them.
Reply with text and no link. Say what you write and who it’s for in one sentence. Your name and profile link already ride along with every reply, so you don’t need to paste a URL. Writer Karen Cherry makes the same point about link dropping. This is my default.
Reply with a link, done right. Point to one specific post on your own Substack and add one line: who it’s for and what they’ll get. “My post on X for people trying to Y.” Not your homepage. Not “check out my stuff.”
Skip it. In a thread with 400 replies, yours lands at the bottom. Ten minutes go further reading five posts in your niche and leaving three real comments. Zakharova suggests new writers spend about 70% of their time on conversation and 30% creating.
Post your own note instead. Zakharova’s on-topic tip Notes earned about 7 likes and no subscribers. Then she posted about hitting 44 subscribers and doubting it was working: 132 likes, 31 comments, 20 new subscribers. People rarely follow the most useful note. They follow the person they feel like they know. Keep it human, keep it over 150 characters, and leave the link out.

What to ask so people answer with more than a link
According to WriteStack’s analysis, 62% of Notes get zero replies. A good question is specific enough to answer in one sentence and doesn’t invite a link dump. Try these:
What’s the one thing you wish someone had told you at your first 50 subscribers?
What did you stop doing this month that made your writing better?
Which writer in your niche should everyone here be reading, and why?
What’s the best comment anyone has left on your work?
The third one does the most work. It’s generous, it gets the writer you name to notice you, and Substack reportedly leans on audience overlap when it decides who sees a Note.
I’ve been in podcasting since 2004, and every platform with a discovery feature grows a ritual like this one. It feels like activity. Activity isn’t growth. Show up in other people’s work, post something human, and treat a link like money you spend.

FAQ
Does posting a “drop your link” note on Substack actually get you subscribers?
It can, but the groundwork decides it. One writer picked up 79 new subscribers in two days from a drop-your-link note after a month of daily posting, and only 3 from a nearly identical note the month before. Likes and comments alone don’t predict growth: an analysis of 20,066 viral Notes found 40% earned zero subscribers.
Should I reply to those threads with a link to my Substack?
Only if you do it well. A bare link is the weakest reply. Better: one sentence on what you write and who it’s for, no link, since your profile travels with every reply. If you do link, point to one post on your own Substack and say who it’s for. Or skip the thread and comment on posts in your niche.
Do links hurt Substack Notes?
They cost reach. An analysis of about 655,000 Notes from July 2026 found a link cut median likes from 4 to 2. Short Notes under 150 characters with a link did worst, with 40.7% getting zero likes. Links to your own Substack convert better per like than links to other sites, so if you link, link there.
What should I post on Substack Notes instead of links?
Human notes without a link, longer than 150 characters. One writer’s on-topic tip Notes earned about 7 likes and no subscribers. A note about hitting 44 subscribers and doubting it earned 132 likes and 20 new subscribers. Ask questions people can answer in a sentence, and recommend other writers in your niche.
How many subscribers does a viral Substack Note bring in?
Fewer than you’d guess. In an analysis of 35,845 Notes from May 2026, Notes with 250 to 999 likes averaged about 17 new subscribers, and Notes over 1,000 likes averaged 15, though that top group was small. Notes under 20 likes averaged 0.12. Likes help, but they aren’t the same thing as growth.
