Claude Can Now Do SEO Like a $10,000/Month Agency (For Free)

I spent last week stress-testing every SEO workflow I could think of inside Claude Cowork.

The results changed how I think about SEO execution entirely.

Competitor analysis that used to take 3-4 hours? Done in 12 minutes. Technical audits that required $200/month tools and a specialist? Handled by a single prompt. Keyword research that junior analysts would spend a full day on? Finished before my coffee got cold.

The output quality is genuinely on par with what mid-tier SEO agencies deliver for $5K-$10K/month.

Quick context for those unfamiliar: Claude Cowork is not a chatbot. It launched in January 2026 as an autonomous AI agent that lives inside the Claude desktop app. You give it a task, point it at a folder or a website, and it executes. It reads files, opens Chrome, visits pages, runs analysis across multiple tabs, and delivers structured outputs like spreadsheets and reports. All locally on your machine.

It is available on Pro ($20/month), Max ($100-200/month), Team, and Enterprise plans. Mac and Windows.

Below are 15 ready-to-use prompts that cover the full SEO operation. I organized them into 6 categories so you can jump straight to what matters most for your business right now.

What you’ll get from this guide

I wanted to build the most comprehensive, actually useful SEO resource I’ve seen for Claude Cowork. Here is what is inside, section by section:

Research and Competitive Intelligence (Prompts 1-3)

Map your competitive landscape, reverse-engineer their keyword strategy, and find the exact content gaps worth filling. This is the foundation. Everything else builds on it.

Keyword Strategy (Prompts 4-5)

Two different workflows depending on your business model. One for local and service businesses. One for SaaS and online companies. Both focused on keywords that drive revenue, not vanity metrics.

Technical SEO Audits (Prompts 6-8)

Full site health checks, schema markup validation with JSON-LD generation, and internal linking analysis. The diagnostic work agencies charge $2K+ for.

Content Optimization (Prompts 9-11)

On-page scoring for existing pages, pre-publish checklists for new content, and E-E-A-T analysis against Google’s September 2025 Quality Rater Guidelines. Get more traffic from content you have already written.

Local SEO and Google Business Profile (Prompts 12-13)

Competitor-informed GBP post generation and a full 30-day posting calendar. The most underutilized free channel for local businesses.

Backlinks and Reporting (Prompts 14-15)

Reverse-engineer competitor backlink profiles into a 90-day outreach plan, plus a monthly reporting framework you can reuse every month.

Bonus: The Claude SEO open-source skill

A Claude Code extension with slash commands that takes this even further. Includes AI search optimization for Google AI Overviews, Perplexity, and ChatGPT.
