So you want to repurpose your content from Facebook Posts to Substack Notes?

I get it. You’ve spent hours crafting thoughtful Facebook posts, engaging with your audience, and building your expertise. Now you’re looking at Substack and wondering: “Can I make this work for me too without starting from scratch?”

You’re not alone.

Many content creators feel stretched thin trying to maintain presence across multiple platforms. The thought of creating unique content for each one is exhausting.

But what if I told you that your existing Facebook content could find new life—and potentially reach an entirely different audience—on Substack Notes?

Why you should repurpose from Facebook Posts to Substack Notes

Most creators don’t realize that content performs differently across platforms—sometimes dramatically so.

Back in 2020, I created several YouTube videos about note-taking that didn’t gain much traction. On a whim, I decided to repurpose that content for Medium articles. The result? Those repurposed pieces helped me launch a profitable 5-figure course and add 3,000 email subscribers to my list in just 12 weeks.

This difference isn’t random. It happens because of:

  • Different audience demographics on each platform
  • Platform-specific algorithms favoring certain content types
  • Timing and context of consumption
  • Format preferences (text vs. video vs. images)

Facebook Posts might reach your existing network, but Substack Notes can connect you with an entirely new audience hungry for your expertise.

The main differences between Facebook Posts and Substack Notes

Facebook Posts are designed for feeds and social circulation. They reward emotional reactions, controversy, and content that drives comments.

Substack Notes, meanwhile, functions more like a cross between Twitter and a blog. It’s designed for thoughtful, concise insights from writers people already follow or want to discover.

Key differences:

  • Facebook: More casual, ephemeral, algorithm-dependent
  • Substack Notes: More intentional, discoverable by interest, writer-focused
  • Facebook: Broad audience, friends and family
  • Substack Notes: Niche audience, deliberately seeking quality content
  • Facebook: Mixed media preference
  • Substack Notes: Text-forward with occasional images

Why you should post on Substack Notes

Substack Notes creates unique opportunities for experts like you:

1. It’s a gateway to Substack’s ecosystem of paid newsletters

2. The audience actively seeks valuable knowledge (not just entertainment)

3. It’s still growing, meaning less competition and more opportunity

4. Notes can drive discovery of your deeper content

5. The platform is designed for monetization of expertise

What makes good Substack Notes content

Unlike Facebook, where personal updates thrive, Substack Notes rewards:

  • Concise, valuable insights (think: one clear takeaway)
  • Thoughtful questions that demonstrate expertise
  • Bite-sized teachings from your knowledge base
  • Behind-the-scenes glimpses of your expert process
  • Short-form opinions on industry trends

For example, a financial advisor’s Facebook post about “5 ways to save for retirement” might become a Substack Note like:

“The biggest retirement mistake I see smart professionals making? Maxing out their 401k before funding a Roth. Here’s why that order matters if you earn above $150k…”

Notice how it’s more pointed, assumes expertise, and creates curiosity.

Build Your Swipe File Of Winning Substack Notes content

The secret to mastering any platform is studying what already works there—especially content from newer creators getting traction.

Don’t just copy the big names. They can succeed despite the platform rules, not because of them. Instead:

1. Find 5-10 emerging creators in your niche on Substack Notes

2. Save their most-engaged Notes (look for hearts and comments)

3. Analyze patterns: length, tone, hooks, content type

4. Create a template based on these patterns

This requires upfront work but will save you countless hours of trial and error.

Set up an automation to turn Facebook Posts to Substack Notes

Okay, so now that you have these insights laid out…

You could either do this manually like a monkey.

Hire a VA that you need to train for weeks on Fiverr…

Or (my favorite way):

You could use AI and automation tools to make this process as smooth as butter.

Here’s an example:

As soon as you post on Facebook, an automation triggers that extracts your post, reformats it for Substack’s audience, and queues it for publishing.

Tools like Zapier, Make (formerly Integromat), or n8n can handle this workflow:

1. Facebook Post → Webhook trigger

2. Text sent to AI prompt (like ChatGPT API)

3. Prompt: “Transform this Facebook post into a thought-provoking Substack Note that feels more concise and insight-driven. Add an engaging hook at the beginning and a thought-provoking question at the end. Keep the core message but optimize for a reader seeking expert knowledge.”

4. Reformatted content → Substack API (or draft email)

With this system, you create once but reach two entirely different audiences, doubling your impact without doubling your work.

Stop treating platforms as separate islands. Your knowledge deserves to travel, reaching everyone who needs it—wherever they prefer to consume content.
