who it's for

Who Claude Seo is for#

SEO agencies running weekly client audits

Claude SEO cuts a full audit from 4 to 8 hours down to 10 to 15 minutes, so agencies can run audits before every client check-in rather than quarterly. The /seo drift command monitors for SEO regressions between audits using SQLite snapshots, catching technical problems before they compound into ranking drops.

Skip if:

Your clients primarily need bulk crawl data exports from very large sites with hundreds of thousands of URLs. Claude SEO excels at prioritized analysis; raw bulk crawling at that scale is better served by a dedicated crawler like Screaming Frog.

In-house SEO teams at SaaS and e-commerce companies

The /seo ecommerce command covers product pages and marketplace intelligence. The /seo geo and /seo agentic commands check AI search readiness for brands that want to be cited in Google AI Overviews, ChatGPT, and Perplexity. The /seo google command connects Search Console and GA4 for live field data, with your API keys staying on your machine.

Skip if:

Your team's primary need is keyword rank tracking across thousands of keywords over time. Claude SEO audits a site's current technical and content state; it does not replace a dedicated SERP rank tracker.

Freelance SEO consultants scoping new clients

Running /seo audit <url> on a prospect's site before the first call takes 10 to 15 minutes and produces a prioritized action plan with a real score. Showing a concrete deliverable in the first meeting changes the proposal dynamic compared to consultants who rely on manual audits or generic exported dashboards.

Skip if:

You primarily sell backlink acquisition or content production services. Claude SEO is audit and technical analysis; it does not build links or write content at scale.

Developers building or launching SEO-sensitive sites

The /seo schema command generates JSON-LD markup directly and validates existing blocks. The /seo sitemap command validates or generates XML sitemaps. For developers building with Next.js, React, or Vue, the headless browser automatically renders JavaScript before auditing. The /seo setup command creates an isolated Python environment and headless browser without touching the system.

Skip if:

Your site is pre-launch or not yet indexed. Checks that use Search Console, Chrome UX Report field data, or crawl budget analysis need real traffic and indexing to return meaningful results.

the problem

The problem it solves#

Running a professional SEO audit requires checking dozens of independent areas: crawlability, indexing, page speed, Core Web Vitals, structured data, E-E-A-T content signals, AI search readiness, local citations, backlinks, and international hreflang tags. Doing it by hand takes 4 to 8 hours per site. Hiring an SEO agency runs $2,000 to $15,000 per project. Paid audit tools each cover a different slice and charge $99 to $449 per month, but none of them produce a single prioritized action plan or cover the AI search changes that now affect how Google, ChatGPT, and Perplexity surface results.

The harder part is that SEO requirements keep shifting. Google AI Overviews and AI Mode change which pages get cited. New Schema.org types appear. Core Web Vitals thresholds move. Most teams either skip checks they cannot afford to run regularly or maintain multiple tool subscriptions and still miss the gaps between them.

how Claude Seo solves it

How it solves it#

Parallel 17-agent site audit

Runs up to 17 specialist agents simultaneously: technical SEO, content quality, schema, performance, visual QA, AI search readiness, local, maps, backlinks, and more. A full audit completes in 10 to 15 minutes. Each agent covers its domain independently so findings from different areas arrive in parallel, then merge into a single prioritized action plan with verification steps for every recommendation.

AI search readiness scoring (GEO and AEO)

The /seo geo command scores how likely Google AI Overviews, AI Mode, ChatGPT, Perplexity, and Gemini are to cite your pages. It checks that AI crawlers can reach content, reviews brand presence on Wikipedia, Reddit, YouTube, and LinkedIn, and follows Google's published AI Optimization Guide. The /seo agentic command adds Lighthouse Agentic Browsing, WebMCP, and llms.txt checks.

Technical SEO across 9 check categories

The technical agent covers crawlability, indexing, sitemaps, robots.txt, redirects, page speed, Core Web Vitals, image optimization, and hreflang tags. When a page requires JavaScript to render its content, Claude SEO opens it in a headless browser automatically, so single-page apps built with Next.js, React, or Vue are audited as a real visitor sees them.

Schema.org detection, validation, and generation

The schema agent finds existing JSON-LD blocks, validates them against Schema.org specs, and flags content-schema mismatches that confuse search engines. It also generates corrected or new markup directly. Runs as part of the full audit or standalone with /seo schema <url>.

Markdown, PDF, and JSON output saved locally

Every audit saves its findings as Markdown files on your machine. Running /seo google report converts the Markdown into a polished PDF via the Google APIs extension. Reports include a prioritized action plan formatted for client delivery or internal review. No data is sent to a third-party service.

30 commands across 6 categories

Commands cover audits, technical SEO, content and E-E-A-T, schema and AI search, local and e-commerce, plus extensions. Highlights include /seo drift for SQLite-snapshot-based change monitoring, /seo cluster for SERP-based semantic clustering, /seo sxo for search experience analysis, and /seo ecommerce for product pages and marketplace intelligence.

Strengths and trade-offs#

Strengths

Free with MIT license and no per-site or monthly feesClaude SEO is MIT licensed with no usage caps, no per-site pricing, and no telemetry. The only requirement is Claude Code. Paid SEO audit tools charge $99 to $999 per month; a single agency audit runs $2,000 to $15,000. For anyone already on Claude Code, the cost difference is total.
Nearly 20,000 GitHub stars since February 2026The repo reached 19,886 stars and 2,868 forks in roughly eight months, with the last push on 2026-10-22. With 40 open issues and 1,077 passing tests, it shows the commit frequency and community review of an actively maintained tool rather than an abandoned prototype.
Every recommendation includes a way to verify the fixEach finding in the audit report names what the issue is based on, what it depends on to be resolved, and how to confirm it worked. Most SEO tools output a list of warnings; Claude SEO outputs an action plan where closing a recommendation has a defined done-state.
All audit data stays on your machineClaude SEO runs locally inside Claude Code. It does not send your site's audit data to any third-party service. Reports are saved to your local filesystem as Markdown and JSON. For agencies and in-house teams with client confidentiality requirements, this is a material difference from hosted SEO tools.

Trade-offs

-Requires an active Claude Code planClaude SEO is a Claude Code plugin, not a standalone tool. It requires Claude Code 1.0.33 or newer and a Claude plan that covers the model token usage a full audit consumes. A parallel audit using Opus-model agents on a larger site will use a meaningful portion of a Claude plan's token budget. Users without Claude Code cannot install it.
-Not a replacement for deep crawlers on large sitesThe README notes that crawlers like Screaming Frog crawl faster and deeper, and large SEO suites provide larger proprietary datasets. For sites with hundreds of thousands of URLs where raw bulk crawl exports are the primary need, a dedicated crawler remains the right tool. Claude SEO is strongest on auditing, analysis, and prioritization rather than mass URL crawling.
-Live-data extensions require separate paid accountsOptional extensions for SE Ranking (AI Share-of-Voice), Profound (LLM citation time-series), and Bing Webmaster Tools require the user to hold their own account with each service. The extensions pass through Claude SEO but are not included in the free tier. All 30 core audit commands work without any extension.

versus alternatives

Claude Seo vs alternatives#

Claude SEO vs Screaming Frog

Both tools audit websites for SEO issues, but they target different workflows. Screaming Frog is a desktop crawler built for bulk URL analysis on large sites with a proprietary data export model. Claude SEO is a Claude Code plugin that runs specialist agents and produces a prioritized action plan covering technical SEO, content quality, Schema.org markup, and AI search readiness.

Feature	Claude SEO	Screaming Frog
License	MIT (free)	Proprietary ($259/year)
Runs locally	Yes	Yes
AI search readiness	Yes (GEO, AEO, llms.txt)	No
Schema.org generation	Yes	Validate only
Prioritized action plan	Yes, with verification steps	Findings list only
Large-site crawl depth	Limited	Strong (millions of URLs)

Claude SEO is the better choice when you need a fast, full-coverage audit with AI search readiness and a prioritized plan for a site of typical size. Screaming Frog remains the better tool when you need to crawl millions of URLs, export raw link data in bulk, or build a visual sitemap from a large crawl.

Claude SEO vs Semrush

Semrush is a paid SEO suite starting at $139 per month that covers keyword research, rank tracking, backlink analysis, and site auditing. Claude SEO covers auditing, not keyword tracking or rank history, but it includes AI search readiness checks that Semrush does not offer and runs as a free, local Claude Code plugin.

Feature	Claude SEO	Semrush
License	MIT (free)	Proprietary ($139+/month)
AI search readiness	Yes	Limited
Keyword rank tracking	No	Yes
Backlink database	Moz, Bing, Common Crawl	Large proprietary
Self-hosting	Yes (local)	No (cloud only)
Audit output	Prioritized plan with verification	Findings dashboard

Claude SEO is the better choice for teams that want audit coverage without a monthly subscription and need AI search readiness included. Semrush is the better choice when your primary need is keyword research, SERP rank tracking over time, or access to a large proprietary backlink database.

frequently asked

FAQ#

Does Claude SEO cost anything beyond a Claude Code plan?

No. Claude SEO is MIT licensed with no per-site fees, no subscription, and no usage limits beyond what your Claude plan covers. You only need Claude Code 1.0.33 or newer. Optional extensions for SE Ranking, Profound, and Bing Webmaster Tools require separate accounts with those services, but all 30 core audit commands run without any extension.

How does Claude SEO differ from Screaming Frog or Semrush?

Screaming Frog crawls faster and deeper on large sites; Semrush provides a larger proprietary keyword and backlink dataset. Claude SEO covers audit analysis and prioritization, including AI search readiness (GEO, AEO, llms.txt checks) that most paid tools do not yet offer. It runs locally on your machine, costs nothing beyond Claude Code, and produces a prioritized action plan rather than a data export.

Does it work on JavaScript-rendered sites like Next.js or React?

Yes. When a page requires JavaScript to render its content, Claude SEO opens it in a headless browser automatically. Sites built with Next.js, React, or Vue are audited as a real visitor sees them, not as the raw HTML response. The /seo setup command installs the headless browser in an isolated environment without affecting the rest of your system.

Can I connect Google Search Console and Google Analytics?

Yes, via the free Google APIs integration. Running /seo google setup connects Google Search Console, PageSpeed Insights, Chrome UX Report, Google Analytics 4, and the Indexing API. Your API keys stay on your machine and are not sent to any third-party service. Running /seo google report converts audit Markdown into a polished PDF.

Is the public GitHub version the same as the AI Marketing Hub Pro version?

The public MIT-licensed version includes all 26 sub-skills and 19 specialist agents and is free for everyone. AI Marketing Hub Pro members get access to a private version with early access to new features before they land in the public release. Both versions install as Claude Code plugins and use the same /seo command set.
