If you are thinking about publishing more of your ideas online, it is easy to get stuck on the platform decision.
Should you use Substack?
Should you publish on Medium?
Should you write directly on LinkedIn?
Should you create a blog on your own website?
Those are useful questions, but they are not the best place to start.
The platform is simply the place where your ideas are published or distributed. The bigger opportunity is building a system that helps the right people discover your thinking, engage with it, and continue hearing from you.
Here is how I would approach it.
Start With the Audience, Not the Platform
Before deciding where to publish, think about who you want to reach and where those people already spend their time.
Where do they currently discover ideas?
Where are they most likely to read something longer?
Where do they participate in conversations?
Where are they already connected to you?
For example, if you already have a meaningful audience on LinkedIn, that existing audience should play a major role in the strategy.
Even if you choose Substack as the primary home for your long-form thinking, I would still distribute those ideas to LinkedIn consistently.
You do not want to start publishing somewhere new and leave behind people who may already be interested in what you have to say.
Separate Creation From Distribution
Your ideas do not have to live in only one place.
You can have a primary home for your deepest, longest-form thinking while using several other channels to distribute and promote those ideas.
That could mean publishing a full article or newsletter on Substack and then creating shorter LinkedIn posts that introduce the idea and direct people to the full piece.
Think of the shorter content like a commercial for a show.
The commercial is not the full experience. Its job is to get the attention of the right people and give them a reason to go watch.
You could also potentially syndicate the full piece across multiple platforms.
That does not always mean publishing the exact same format everywhere. A newsletter and a blog often organize and deliver information differently, so you may want to also include a monthly digest-style newsletter that summarizes separate blog posts that are easier to discover, read, share, and rank in search. I explain that distinction in more detail in Newsletter vs. Blog: How to Publish Your Content Across Both
Think of a television episode that airs on ABC, becomes available on Hulu, and then appears on Netflix later. It is still the same episode. It is simply being distributed in several places so more of the right people can find it.
This means the platform where the content lives does not have to be the same platform where most people discover it.
Bring Your Existing Audience With You
One of the biggest mistakes creators make is starting from zero unnecessarily.
If people already follow you on LinkedIn, subscribe to your emails, listen to your podcast, visit your website, or engage with you somewhere else, use those existing channels to introduce the new publication.
Do not assume people will naturally find your Substack just because you started one.
Remind them that it exists.
Share excerpts.
Publish key takeaways.
Ask questions related to the article.
Turn one section into a standalone LinkedIn post.
Bring the best ideas back into the channels where you already have attention.
The goal is not to force everyone onto one platform immediately. The goal is to consistently help interested people discover more of your thinking.
One Idea Can Appear in Multiple Forms and Places
You do not have to choose between promoting the original piece and publishing the idea elsewhere.
You can do both.
One option is to use shorter content to promote the complete article.
Another option is to syndicate the full content across multiple platforms.
Think about how a television episode might originally air on ABC, become available on Hulu, and later appear on Netflix.
It is still the same core content. It is simply being distributed through several channels to reach different audiences.
Your long-form article could become:
- A Substack newsletter
- A blog article
- A LinkedIn article
- Several shorter LinkedIn posts
- A series of emails
- A video or podcast discussion
- A collection of quotes, clips, or graphics
- A conversation prompt for your community
You do not need a completely new idea for every platform.
You need a strong idea and an effective way to adapt and distribute it.
Build an Email List as the Durable Asset
The real goal is to build an actual relationship with people, regardless of which channel they first discover you on.
Someone may initially find one of your ideas on LinkedIn, read the complete piece on Substack, visit your website later, and eventually reply to one of your emails.
Those channels are simply different touchpoints within the same relationship.
No matter which publishing platform you choose, building your email list should be a major priority.
Social media gives you reach, but email gives you direct access to the people who have asked to continue hearing from you.
If you build the newsletter on Substack, make sure you are regularly backing up your subscriber list.
That could be as simple as exporting the list into a spreadsheet or setting up an automated process through a tool like Zapier.
Platforms can change.
Algorithms can change.
Features can disappear.
Your direct relationship with your audience is much more durable.
The best outcome is not simply having more readers on a platform. It is building a growing group of people who have given you permission to stay in touch with them.
Create an Ecosystem, Not Another Content Obligation
The care and feeding of a newsletter can become overwhelming if you treat every edition as a completely separate project.
Instead, build a system where each strong idea can create several useful pieces of content.
A long-form article can become multiple shorter posts.
A short post that generates a strong response can become the foundation for a deeper article.
Questions in the comments can give you ideas for future newsletters.
A conversation with someone in your audience can become a podcast episode, article, or follow-up email.
The goal is not to constantly feed another platform with brand-new material.
The goal is to create a connected body of work where each idea supports the others.
That makes publishing more sustainable and helps your thinking compound over time.
Discovery and Engagement May Happen in Different Places
There may not be one platform that is best at everything.
LinkedIn may be the best place for discovery because you already have an audience there.
Substack may be a strong place for publishing and sending the newsletter.
Your website may be the best long-term archive and the strongest place to build SEO and AEO visibility.
Email may be the best channel for consistently bringing people back.
Comments, direct messages, or a community platform may be where the deepest conversations happen.
That is perfectly fine.
You do not need one platform to handle the entire relationship.
You need each channel to play a clear role.
For example:
LinkedIn creates discovery and conversation.
The newsletter deepens the relationship.
Your email list gives you ongoing access.
Your website creates a searchable library of your thinking.
Each part supports the others.
Start With a Clear Value Proposition
Before worrying too much about publishing frequency, cross-posting, or platform features, get clear on why someone would want to subscribe.
A broad collection of thoughts across several different subjects may accurately describe what you want to write about, but it may still be too general to give people a compelling reason to follow.
What is the connecting thread between those subjects?
Who will find your perspective most useful?
What will they understand, see, or be able to do differently after reading your work?
Why should they subscribe instead of simply reading an occasional post when it appears in their feed?
A strong publication needs an irresistible value proposition just like a strong podcast, offer, or business.
The clearer the promise, the easier it becomes to attract the right readers and turn occasional discovery into consistent engagement.
Build the Publishing System Around the Goal
If the goal is discovery and engagement, I would not treat Substack, Medium, LinkedIn, or your website as mutually exclusive choices.
Choose a primary place for the long-form thinking to live.
Use the channels where you already have an audience to distribute it.
Give interested readers a clear way to join your email list.
Create a welcome experience that introduces them to your best work.
Publish consistently enough to remain connected without creating a schedule you cannot sustain.
Turn each long-form idea into several opportunities for discovery, conversation, and engagement.
The real decision is not simply where you should publish.
It is how you will build a system around your ideas so the right people can find them, engage with them, and continue following your work over time.
