Claude Skill
Updated: July 25, 2026

What Is A Claude Skill?

A Claude Skill is a reusable workflow system inside Claude.

Instead of:

→ writing massive prompts every time

→ repeating your writing style

→ manually adding SEO instructions

→ fixing internal links yourself

You package everything once.

Then Claude remembers your workflow every time you activate the skill.

Think of it like this:

Normal prompting:

You train a freelancer every single day.

Claude Skills:

You train an employee once.


Why Claude Skills Matter For SEO

Most people use AI like this:

→ open Claude

→ type random prompt

→ get generic article

→ spend 1 hour rewriting everything

The biggest problem:

AI forgets everything in every new chat.

Your:

✓ tone

✓ structure

✓ website pages

✓ writing preferences

✓ SEO rules

✓ internal links

All disappear.

Claude Skills solve this problem.


Difference Between Skills, Projects, And Custom Instructions

1. Custom Instructions

Global settings across all chats.

Example:

→ “Always answer concisely”

→ “Act like a software engineer”

Always active.


2. Projects

A workspace with:

→ documents

→ instructions

→ files

Useful for specific projects.


3. Claude Skills

Skills are activated only when needed.

Most important difference:

Skills can include external files.

Example:

✓ style guides

✓ CSV files

✓ screenshots

✓ case studies

✓ writing samples

✓ sitemap data

This makes outputs far more personalized.


What You Need Before Building The Skill

You need 3 core documents.

These documents are the real engine behind the SEO skill.


Document 1. Tone Of Voice File

This teaches Claude:

→ how you write

→ how you structure sentences

→ phrases you use

→ phrases you hate

→ your communication style

Without this:

AI sounds generic.

With this:

Claude sounds like you.


What To Include

Writing Style

→ conversational

→ direct

→ technical

→ educational

→ storytelling

Sentence Structure

→ short sentences

→ long explanations

→ humor level

→ formatting style

Words You Avoid

Very important.

Example:

Avoid:

✗ “game changer”

✗ “revolutionary”

✗ “unlock”

✗ “delve into”

This removes obvious AI writing patterns.


Best Way To Create It

Do NOT write this manually.

Instead:

  1. Gather: → old blog posts → YouTube scripts → newsletters → emails
  2. Upload them into Claude.
  3. Ask: “Analyze my writing style and create a detailed tone of voice document.”

Claude generates the file automatically.


Document 2. Mini Sitemap CSV

This helps Claude create internal links correctly.

Without this:

AI invents random links.

With this:

Claude links to real pages on your site.


What To Include

You only need:

✓ important pages

✓ blogs

✓ products

✓ landing pages

✓ course pages


CSV Structure Example

Document 3. Experience Document

✓ case studies
