FAQ
What is SEO Machine?
A specialized Claude Code workspace for creating long-form, SEO-optimized blog content. It covers the full content workflow — research, writing, analysis, optimization, and publishing to WordPress — but focuses on creation rather than auditing. Free under MIT license.
How much does SEO Machine cost?
Nothing — it is open source under MIT license with no hosted or paid tier; seomachine.io is a landing page that points to the GitHub repo. You pay for what it consumes: Claude Code usage plus optional third-party APIs like DataForSEO, which have their own pricing.
How does SEO Machine differ from other SEO tools?
Most tools in the category audit existing sites. SEO Machine creates new content. It is the right tool when you need to write SEO-optimized blog posts, not when you need to diagnose why existing pages underperform.
Does SEO Machine support GEO?
Minimally. SEO Machine was created before the GEO wave (October 2025) and focuses on traditional search content optimization. For GEO-optimized content creation, pair it with a GEO tool like geo-seo-claude.
Who created SEO Machine?
Craig Hewitt (TheCraigHewitt on GitHub), who originally built it for his company Castos before open-sourcing it. The content-first approach solves the problem content teams actually face: producing optimized articles at scale.
Overview
SEO Machine is the content creator's entry in the SEO/GEO agent skills category — while every other tool audits existing sites, this one creates new SEO-optimized content from scratch. It is a specialized Claude Code workspace for researching, writing, analyzing, optimizing, and publishing long-form blog content, built by Craig Hewitt and originally developed for his company Castos.

How It Works
SEO Machine operates as a Claude Code workspace — a preconfigured environment that guides Claude through a content creation pipeline. Rather than standalone commands, it structures the entire content production workflow:
Content Workflow
| Phase | What Happens |
|---|---|
| Research | Topic analysis, keyword identification, competitor content review (/research, /research-serp, /research-gaps, /research-trending) |
| Write | Long-form blog content generation with SEO structure (/write, /rewrite) |
| Analyze | Content quality assessment, keyword distribution, readability (/analyze-existing) |
| Optimize | Title tags, meta descriptions, headings, internal linking (/optimize) |
| Publish | WordPress REST API publishing with Yoast SEO metadata (/publish-draft) |
Data Integrations
Since the March 2026 profile, the workspace has grown into a data-connected pipeline. It integrates Google Analytics 4 (traffic and engagement metrics), Google Search Console (rankings, impressions, CTR), DataForSEO (competitive rankings, SERP features, keyword metrics — a paid third-party API), and the WordPress REST API for publishing. It also ships landing-page variants (/landing-write, /landing-audit, /landing-research), 26 marketing skills covering copywriting, CRO, and email sequences, and specialized agents including a Content Analyzer, SEO Optimizer, Meta Creator, Internal Linker, and CRO Analyst.
The Content Gap
This workflow addresses a real gap. Most SEO tools tell you what is wrong with existing content. They don't help you create new content that is right from the start. SEO Machine flips the script: start with research, produce optimized content, then analyze and refine. The creation step — the hardest and most time-consuming part for content teams — is the core capability.
Workspace Architecture
The "workspace" approach (vs. discrete skills) means SEO Machine sets up the entire Claude Code environment for content work. Context, instructions, and workflows persist across the session. You are not running individual commands — you are working within a content production environment.
Competitive Position
At 7,121 stars as of June 2026, SEO Machine remains the third-most-starred tool in the SEO/GEO agent skills category — behind Marketing Skills (32,921) and geo-seo-claude (8,075). Stars have more than doubled since the March 2026 profile (2,816 → 7,121), reflecting genuine demand for AI-powered content creation at scale.
Its position is non-competitive with most of the category. claude-seo, geo-seo-claude, and Agentic-SEO-Skill are audit tools — they analyze existing sites. SEO Machine is a creation tool — it produces new content. Teams often need both, making SEO Machine complementary rather than competitive with audit-focused tools.
The main weakness is still GEO coverage. Created in October 2025, before the GEO wave hit the agent skills ecosystem, SEO Machine optimizes for traditional search only — the June 2026 README mentions no AI-search or GEO features. As AI-referred traffic grows, content needs to be optimized for AI citation — a gap that pairing with a GEO tool (geo-seo-claude or seo-geo-claude-skills) would address. The project also has a dedicated landing page at seomachine.io, which confirms there is no hosted or paid tier — it points users to clone the GitHub repo.
Strengths
- Content creation focus — fills a gap no other tool in the category addresses
- Strong adoption — 7,121 stars and 968 forks, more than doubled since March 2026
- Complete pipeline — research through WordPress publishing in one workspace, with GA4, Search Console, and DataForSEO data feeding the loop
- Specialized agents — Content Analyzer, SEO Optimizer, Meta Creator, Internal Linker, and CRO Analyst divide the work
- Early mover — October 2025, well-established and battle-tested
- Complementary — pairs well with audit tools rather than competing
Cautions
- Minimal GEO — does not optimize for AI search engines
- Claude Code only — no support for other coding agents
- Content only — no technical SEO auditing, schema generation, or site analysis
- Development paused — no commits since April 10, 2026, two months before this update; the April batch was bug fixes (DataForSEO error handling, AI-watermark scrubbing)
- Hidden API costs — the data integrations are the differentiator, and DataForSEO is a paid service billed separately
What Developers Say
Third-party commentary is mostly social-share enthusiasm rather than in-depth reviews. A representative reaction on Threads: "A dev just turned Claude Code into an SEO machine... Brand voice, Search Console, GA4, and DataForSEO built in. Useful when too much of the SEO process is still fragmented across separate tools." No substantial verbatim developer commentary surfaced on Hacker News or Reddit as of June 2026 — star and fork velocity (2,816 → 7,121 stars in under three months) remains the best available adoption signal.
Bottom Line
Recommended if your bottleneck is SEO content production rather than site auditing — the research-to-publish pipeline with GA4, Search Console, and DataForSEO data is the most complete content workflow in the category, and it is free under MIT. Not recommended if you need GEO/AI-search optimization, technical site audits, or support for agents other than Claude Code. Outlook: cautious — adoption is strong (stars more than doubled in a quarter), but commits stopped on April 10, 2026; if the two-month pause extends, the unaddressed GEO gap will matter more as AI-referred traffic grows. Pair it with a GEO-aware audit tool (geo-seo-claude for GEO depth, claude-seo for SEO breadth) for full coverage.
