Yesterday, something dropped on GitHub that I had to stop and look at twice. Eleven SEO skills for Claude, built from scratch and released completely free. The author is a Reddit user from r/PromptEngineering with over 10 years of hands-on SEO experience, and these skills reflect that depth. Not a weekend project. A decade of real client work compressed into prompt files.
We’re not talking about generic prompts like “write me a meta description.” This is a full library covering link building, site auditing, and content writing that actually sounds like a human typed it. The repo is called superseo-skills and it’s live on GitHub right now.
Here’s the twist
Most AI SEO content fails the same way. Technically correct, but reads like a robot who memorized every ranking guide ever written. The gap between “Claude wrote this” and “this actually ranks” is real, and a lot of people in the SEO community have felt that frustration for a while now.
What makes this pack different is where it came from. These skills weren’t written by a prompt engineer trying to reverse-engineer SEO. They were built by someone who has done SEO professionally for a decade, working through real campaigns with real clients. That’s a very different starting point. The prompts encode the kind of judgment that takes years to develop through actual client work, real audits, and campaigns that either won rankings or didn’t.
The original poster specifically called out natural-sounding content writing as one of the core skills. That’s the hard part. Getting Claude to write copy that doesn’t trigger every “AI-written” alarm in a reader’s head takes real craft in the prompt design, and that’s exactly what this expert tackled. The skill doesn’t just ask Claude to “write naturally.” It builds in the structural and tonal cues that make the output feel like a person actually thought it through.
One community member raised a sharp question: how do you handle the gap between what Claude generates and what actually ranks? It’s a fair challenge. The answer here is that the skills are built on real SEO principles, not just writing prompts. The author trained Claude on the same mental models that inform their day-to-day SEO work. That’s the leverage.
🔧 How to get started
- Find the superseo-skills repo on GitHub (linked in the original Reddit thread below)
- Clone or download the repo to your machine
- Browse the 11 skill files and pick the one that matches your current task: link building, site audit, or content writing
- Copy the skill into a Claude conversation or use it as a system prompt
- Run your task and compare the output against what you’d normally get from a generic prompt
No setup, no API keys, no configuration. Copy, paste, run.
💡 Pro tips
Start with the content writing skill. That’s where the pain is sharpest for most people. If you see a noticeable quality jump there, the other 10 skills are worth your time. Pay attention specifically to sentence variety and how the output handles transitions between ideas.
Read the skill before you run it. Don’t just paste and go. Look at what the author encoded and why. The real value isn’t the output. It’s understanding what a 10-year SEO pro considers important enough to put in a prompt. You’ll pick up patterns you can apply to your own prompt work.
Pair these with real data inputs. The skills are strong at analysis and writing, but they still need good inputs: keyword research, competitor backlink data, actual site crawl results. Strong skills with weak data still produce weak outputs.
Test the audit skill on a page you already know has issues. It’s the fastest way to calibrate whether the skill is catching the things that actually matter or just flagging surface-level stuff. You already know the answer, so you can see how well the skill’s diagnosis lines up with reality.
Why this is worth your attention
There’s a real shift happening in how professional knowledge gets packaged and shared. Ten years ago, you hired an SEO consultant or paid for a course. Today, that same expertise can live in a prompt file that anyone can run. The barrier between “expert knows this” and “you can do this” is shrinking fast.
This repo is a clear example of that. One person took a decade of hard-earned knowledge and made it free and accessible. The community reaction has been positive, and the questions being raised in the thread are exactly the right ones: how does this hold up against what actually ranks?
That’s the conversation worth following. And now you have the tools to run your own tests and find out.

Frequently Asked Questions
Q: How do you balance naturally-written content with keyword optimization when using Claude for SEO?
This is one of the trickiest parts of AI-assisted SEO writing. You’ll need to iterate on your prompts, providing Claude with examples of naturally-written, high-ranking content helps it learn that effective SEO isn’t about keyword stuffing. Many users find that treating keywords as one factor among readability, user intent, and structure helps Claude produce content that ranks while sounding human. Some also add a manual polish pass before publishing to make sure it reads naturally.
