Almost all of your Substack subscribers will choose whether to subscribe after reading one thing: your publication’s short description.

While it may seem like an afterthought, your short description is crucial to growing your publication and building a strong brand.

For most people, it’s the first thing they’ll read about your publication, and what they read will determine if they decide to subscribe or not.

Your short description is your main sales pitch that will convert most of your subscribers so it’s essential that it adequately conveys your publication’s value.

Where Your Short Description Appears

Your short description will primarily appear in three locations.

Your Author Page

My author page Substack.

Your Welcome Page

Really Good Business Ideas welcome page.

Your Category’s Leaderboard Page

My description on the Substack business leaderboard.

How to Add/Edit Your Short Description

Your short description can be added in your publication’s settings. Navigate to your publication’s “Dashboard” and then to “Settings.”

Then fill in your “Publication short description” in the “Basics” section.

3 Steps for Writing a Perfect Short Description

Your short description can only be up to 255 characters long so each word is important.

1. Gather Your Inspiration

The first step to writing a strong short description is to gather all the inputs you’ll need to come up with great ideas!

Describe Your Ideal Reader

Start by describing your ideal reader. Be as specific as possible. Gaining clarity on who you want to read your publication will make it easier to build a strong pitch that resonates with that audience.

Research Similar Publications

Next, research publications similar to yours by scrolling through the leaderboard page for the category that best matches your publication. Save any that stand out to you and note what they do well.

Develop Your Unique Selling Proposition

Finally, write your unique selling proposition. Your unique selling proposition should describe what makes your publication uniquely valuable. It will generally describe some combination of what you’re good at, what readers want, and what competitors lack.

In many cases, you will find that your unique selling proposition makes a solid foundation for your short description, but it’s best to continue with the process so you can be sure it’s as strong as possible.

2. Generate Ideas

Next, take all the work you did in step one and start developing some short descriptions.

Brainstorm as Many Ideas as Possible

Start by writing as many short descriptions as come to mind. Don’t worry too much about finessing them since you’ll have plenty of time to do that later.

Use AI to Expand Your Brainstorm

Next, use your favorite chatbot to expand your list of ideas. If you’re not sure what to use, Gemini is free and easy to access and my go-to for quick help with brainstorming.

Here’s a prompt you can use.

I’m brainstorming short descriptions for my Substack publication. My ideal reader is [fill in ideal reader description]. My unique selling proposition is [fill in your unique selling proposition]. These are some ideas I already came up with:

[Fill in short description one]
[Fill in short description two]
[Etc]

Can you suggest ten more options for me to consider?

From there, you can tell your chatbot which ones you like and ask it to generate 10 more based on those.

When you’re finished, add all the newly generated ideas to your brainstorm list. It’s unlikely one of the AI-generated descriptions will be better than your own but you will probably find some words or phrases you want to explore.

3. Refine Your Ideas

Finally, refine your ideas and choose a winner.

Create a Shortlist

Create a shortlist of all of the best ideas you generated. If you want to take different parts of different ideas and mix them together now is a good time to do that.

Then, assess your shortlist by asking three questions:

  • Does it accurately convey what my publication is about?

  • Will it make my ideal reader say, “Heck, yes!”?

  • Is it too vague, or, conversely, does it assume readers already know me?

If any ideas don’t meet these criteria, discard them.

Test Your Top Choices

Now, take your top 3-5 and get outside feedback. If possible, ask people who are representative of your ideal reader which one excites them most. It may be someone you know, but it could also be strangers in an online community where your ideal reader hangs out.

Choose a Winner

Finally, using the feedback, choose a winner. If there are strong parts in different options and you want to recombine them, that’s ok too!
