Write2Sell: Which acquisition channel has the highest conversion rate on Substack (and why)

And the content strategy that gets me 9% conversions.

I’m obsessed with numbers. People call me a nerd, and I’m proud of it. The thing is when you run a business you need to speak the language of math.

Or fail until you learn how to speak it.

People keep asking me how do I maintain a high conversion rate. Above Substack average, currently 6%. What’s my secret?

To be honest, I’m not excited. Yes, it’s high, but it’s not great. I’ve seen 11,3% and even 18%. But it’s not terrible either.

One of the main reasons is to know where to focus your growth.

And you’ll know that if you look at the numbers.

Most writers hate numbers. Then struggle with sales. If that’s you, know that you don’t have a conversion problem, you most probably have a channel blindness problem.

If you're posting on Substack, scrambling on Notes, begging for recommendations, promoting like crazy and still wondering, “Why aren’t people converting?, you might just be fishing in the wrong waters.

I know because I tracked mine. Religiously.

So today I’m sharing the raw truth behind my top 3 acquisition channels.

But before that, tell me please:

These aren’t vague “content tips” or algorithm “hacks”.

These are cold hard numbers after 280+ subscriber conversions.

And I’m breaking down:

• What's the most converting acquisition channel

• What actually works in each channel (and why)

• What’s worth your effort (and what doesn’t)

• How to copy my top-performing system starting today

Let’s go!
