I ran a 42-day audience growth experiment on Notes. Here's what I did, and everything I learned.

The results will definitely shape my future approach to Notes.

I may have missed my calling as a scientist.

In Year 11 at school, I once finished top of the class in Physics, completely by accident.

I pretty much guessed my way through the exam.

And when the teacher, beaming from ear to ear, asked why I thought I’d done so well, I made the mistake of telling him just that.

He was not amused.

Ok, so science was never my forte, especially physics (I suck at maths). But I do love experiments. And what could be better than an experiment involving writing?

If you’ve paid any attention to my ramblings over the last few months, you’ll know how much I love Notes on Substack.

It completely changed the game for me at the end of 2023, skyrocketing my previously-stagnant growth on the platform.

And throughout this year, I’ve often wondered if a system could be applied to my Notes-posting process, just like I did on Twitter back in 2022, when my audience there jumped from just 2 people to 16,000+ followers over 12 months.

So, like the good little newsletter growth nerd I am, I decided to run an experiment right here on my current platform of choice, Substack.

Let’s start with the why.

I wanted to see if certain aspects of Notes had any significant impact on audience growth and conversion (from free to paid). These aspects included:

  • Note types

  • Note lengths

  • Text vs image

  • Posting time

  • Posting frequency

It wasn’t an exhaustive list, but it’d give me a fairly good idea of what was working and what wasn’t.

And if I was able to determine what the ideal system for posting Notes looked like, I could replicate it and turn it into a growth lever for my Substack audience.

In short, and as with most of my ventures, I just wanted to see if I could do it.

Next, the how.
