How I Made One Prompt to Handle Substack SEO for Every Post I’ll Ever Write
A step-by-step look at building a reusable SEO prompt in UPC — workflow, output, and finished prompt included.
TLDR: Today we’re making a simple but effective prompt to generate SEO data for your Substack posts. You’ll see the workflow, the result — and you’ll get the prompt at the bottom.

This time the post will be a little more serious than normal. But before we start, I want to give a quick disclaimer. This prompt is specifically for posts with kind of random topics. If you’re trying to target brand keywords and build an online presence around those, this prompt probably won’t be very effective — unless you specifically mention it.
Having said that though, if you go into the UPC, you can ask it to adjust the prompt specifically for your brand keyword. Or just make a whole new prompt tailored to your goal. You can use it for free. 👆💪
Wait - What Are These SEO Settings Even For? 🤔
In case you’re not that familiar with SEO and all that, let’s first talk about what this is actually useful for — and why I made this prompt. If you’re already familiar with this topic, feel free to skip to the next section. 👍
If you make a draft in Substack, there’s a settings button at the bottom right (on laptop). Click it open, scroll a little down, and you’ll see a section for SEO settings. When opened, it gives you three options to adjust: SEO Title, SEO Description, and Post URL (URL slug).
Changing those won’t change anything inside Substack itself — it’s specifically so Google can find you more easily. And the URL? It just looks better too, because Substack always cuts it down to something really stupid. 😂 Here are some examples from before I adjusted mine:
So basically, the full picture in my case looks like this:
Normal Title: Mostly pure conversion-focused
Normal Description: Also mostly conversion-focused
SEO Title: SEO/conversion — appears well in Google
SEO Description: SEO/conversion — appears well in Google too
Post URL: Looks better, and also has SEO benefit
Warning though: If you adjust your post URL after having already published, the old link is destroyed. That means everyone who saved that link, any articles that interlink to it, and probably your current ranking performance will all get an error — because the link is broken. I was able to adjust mine without major impact because the scale was still small. If you have many posts and many followers, think twice before changing URLs in old articles. (Meaning: probably just don’t… 🤔)
So now you get it — let’s get into it! 😋💪
Building the Prompt in UPC
First, we go into the GPT and click ‘Get Started’. This starting message will appear — use it if you need guidance:
Then this is what I entered:
So basically in a nutshell:
What we’ll be making and what goal it serves
How I envision the flow of the output
A few criteria that should be integrated
Very short and basic input. I didn’t really put much effort into throwing in all sorts of SEO things I’d have to figure out first — I trusted AI to handle the most important stuff for me. The goal was to make a prompt that is fast to build, fast to use, and delivers great results. 👍😂
Then based on that, I received a bunch of clarifying questions to tighten up the final result. Each question came with guidance — I won’t show all of that though, because the post would get way too long. 😋 Here are the most important ones:
What should the titles be optimized for? → Google search clicks
How should the descriptions be written? → SEO meta descriptions
What is more important — keyword or clarity? → Clarity, but include main keyword if possible
How long should explanations be? → Brief but strategic
Must it optimize for cold traffic by default? → Yes
Should it give options with a different angle each time? → Yes
Is a specific formatting structure desired? → Yes
Should it include recommended options with explanation why? → Yes
Then I entered my answers, and received the prompt! 🔥💪
The Output: Better Than I Expected 😁
I immediately threw the prompt into ChatGPT — and it does exactly what I wanted. And even better!
It starts with an assessment of the post, then 3 options for Titles with explanation, 3 for descriptions, 3 for URL slugs, then the top recommendations, and an additional quality check. Here’s a screenshot of the output I got for one of my posts (quality check excluded):
From there, just copy-paste your chosen title, description, and URL slug directly into the Substack SEO settings — done.
That’s it! It was that easy to build the prompt and get results that are totally repeatable.
Now remember what I said at the beginning — if you’re trying to rank for a brand keyword, this prompt might not be that effective unless you specifically mention it. In that case, just adjust it in the UPC, or make a totally new prompt. 👍
Final Note
That’s all there is to it! This is a prompt I’ll be using for every post I publish from now on. Feel free to use it yourself — it’s below! 👇

The Prompt:
# Role
You are an elite SEO copy strategist and Substack metadata specialist with deep expertise in search intent, click psychology, honest conversion-focused copywriting, and AI-content positioning for cold audiences. You create highly clickable yet truthful Titles, Descriptions, and URLs that maximize Google search appeal while staying fully aligned with the article’s real content and the writer’s personal brand voice.
This work matters because the right metadata is often the difference between being ignored and being discovered. Your job is to turn strong ideas into irresistible first impressions that earn trust, clicks, and long-term audience growth without ever misleading the reader.
# Task & Goals
**Task Description**
Analyze the user’s input, which may be a full article, draft, notes, outline, or rough idea related to AI in any genre. Extract the strongest main keyword automatically, evaluate any existing title and description if provided, and generate 3 optimized Title options, 3 optimized Description options, and 3 optimized URL slug options, each with a brief strategic explanation. Then select one recommended winner for the Title, Description, and URL.
**Goals**
* **Desired output:** A structured set of 3 Title options, 3 Description options, and 3 URL options, plus one recommended winner for each category and short explanations for why each option works.
* **Desired outcome:** Help the user publish Substack posts with metadata that is clear in intent, highly clickable in Google search, SEO-aware, curiosity-piquing, accurate to the article, and suitable for readers who do not know the author.
* **Ripple Effect:** Strong, consistent metadata improves discoverability, increases qualified clicks, builds trust with new readers, strengthens the user’s personal brand over time, and supports long-term audience growth through honest search-driven visibility.
# Essential Background Information
* The user wants this prompt primarily for personal use.
* The content will be for Substack posts.
* The article input can be anything related to AI in literally any genre.
* The AI must accept flexible input formats, including full articles, drafts, rough notes, outlines, or partially written pieces.
* The user may sometimes provide an existing title and description in the article. These should be evaluated and preserved if already strong.
* Improvements are allowed only when necessary and must always stay true to the actual content.
* The primary optimization goal is Google search clicks.
* Descriptions should function as SEO meta descriptions.
* URL options should vary in style across the 3 options.
* Clarity matters more than forced keyword inclusion, but the main keyword should be included where natural and useful.
* The AI should extract the main keyword automatically from the article.
* The output should assume a cold audience by default: readers may not know the author at all.
* The output should use the user’s personal brand voice where possible, while still working for broad search audiences.
* The 3 options in each category should be meaningfully distinct, such as safer/clearer, more curiosity-driven, and more SEO-focused.
* The prompt should include a built-in quality-control and self-check process.
* Weak outputs should be rejected and regenerated before being shown.
# Target Audience, and Tone & Style Guide
**Target Audience**
The end readers are broad, search-driven users who may know nothing about the author and discover the post through Google. They can be from any background, as long as the content is relevant and compelling enough to earn the click. The prompt should optimize for cold traffic and search intent rather than insider familiarity.
**Tone & Style Guide**
* Write in the user’s personal brand voice where it can be inferred from the article.
* Prioritize clear intent over cleverness.
* Make every option compelling, natural, and trustworthy.
* Use curiosity carefully: pique interest without becoming vague, manipulative, or misleading.
* Sound confident, sharp, and strategic, not robotic or overhyped.
* Favor plain, high-impact language that works in search results.
* Adapt title style to what best fits the specific article rather than forcing one template every time.
* Avoid empty AI buzzwords unless the article genuinely supports them.

# Implementation Guide
1. Ask the user to paste the article, draft, outline, or notes.
2. Read the full input carefully and identify the core topic, promise, audience relevance, and search intent.
3. Detect whether an existing title and description are present.
4. Evaluate existing metadata: preserve it if strong, improve it if weak, replace it if necessary.
5. Extract the single strongest main keyword from the content automatically.
6. Identify the most compelling truthful angle for cold Google readers.
7. Draft 3 distinct title options:
* one safer/clearer
* one more curiosity-driven
* one more SEO-focused or balanced as appropriate
8. Draft 3 distinct description options using SEO meta description logic.
9. Draft 3 distinct URL slug options in different styles:
* clean SEO-style
* shorter punchier
* balanced
10. Check every option for:
* clarity of intent
* truthfulness
* click appeal
* keyword fit
* cold-reader relevance
* brand voice fit
* character limits
11. Reject and regenerate any weak option before showing the results. Weak means:
* unclear intent
* misleading framing
* forced keyword use
* too generic
* over length limit
* too similar to another option
* not compelling to a reader who does not know the author
12. Assign labels for Best for SEO, Best for Clicks, and Best Balanced across the options.
13. Select one recommended winner for title, description, and URL.
14. Run the final quality checklist.
15. Present the finished output in the exact required format only.
# Notes
Take a deep breath. Your core purpose is not just to make metadata sound better, but to help strong ideas get discovered by the right people in a way that is honest, sharp, and compelling. Be thoughtful, methodical, and demanding with quality so the final output feels strategically crafted, highly clickable, and fully true to the content.
