AgriciDaniel/claude-seo

Claude SEO is an open-source SEO analysis plugin for Claude Code. It runs 26 sub-skills and 19 specialist agents in parallel across technical SEO, content quality (E-E-A-T), Schema.org markup, AI search optimization (GEO), local SEO, e-commerce, and international SEO. Every audit produces a prioritized action plan with testable recommendations grounded in primary-source guidance from Google.

Two versions of this skill.

• 🌐 Public open-source → AgriciDaniel/claude-seo: MIT, public releases, no membership. Use this if you want stable + downloadable.
• 🔒 Community private mirror → AI-Marketing-Hub/claude-seo: early access to upcoming features and direct collaboration with the AI Marketing Hub Pro community. Requires membership.

• AI-search first. Aligned with Google's AI Optimization Guide. Question-based citability scoring, primary-source evidence on llms.txt, IPTC TrainedAlgorithmicMedia for AI-generated product images, agent-friendly page checks per web.dev, and /seo agentic for agent readiness scored the way Lighthouse's Agentic Browsing category counts it.
• Parallel execution. Full site audits spawn up to 17 specialist agents simultaneously. Site-level audits complete in minutes rather than hours.
• Falsifiable, not promotional. Every recommendation carries the first-principle observation it rests on, its dependency relationships, an explicit "how would we know this failed?" check, and a leading indicator. See Methodology.

• SEO agencies running 5+ client sites. Replace quarterly deep audits with weekly automated runs. Same team capacity, 4× audit cadence, every recommendation comes with a falsifiability check the client can verify.
• In-house SEO leads at SaaS / publisher / e-commerce companies. Second-pair-of-eyes before executive reviews. Catches what GSC and Lighthouse hide: schema deprecation, AI-citability gaps, expired-domain heritage risk, parasite-SEO exposure, machine-translation drift.
• Freelance SEO consultants. Anchor day-one client scope with a 15-minute audit and a real 0-100 score. Win the engagement with concrete proof of value before you spend an hour writing the proposal.

ℹ️ Which version are you installing?

• Public open-source (default). The commands below install from AgriciDaniel/claude-seo: MIT, public releases, no membership required.
• AI Marketing Hub Pro member? Install the community version with early access instead: swap AgriciDaniel/claude-seo for AI-Marketing-Hub/claude-seo and the plugin slug claude-seo@agricidaniel-claude-seo for claude-seo@ai-marketing-hub-claude-seo. Requires gh auth login (or PAT) with access to the AI-Marketing-Hub org. If /plugin marketplace add 404s, DM in the Skool community to get added.

The fastest path. One-time marketplace add, then plugin install:

/plugin marketplace add AgriciDaniel/claude-seo
/plugin install claude-seo@agricidaniel-claude-seo
/seo setup

The explicit setup step creates an isolated Python environment in Claude's persistent plugin data and installs Playwright Chromium. Check it at any time with /seo doctor. No global Python packages or PATH shims are created.

git clone --depth 1 https://github.com/AgriciDaniel/claude-seo.git
bash claude-seo/install.sh

curl -fsSL https://raw.githubusercontent.com/AgriciDaniel/claude-seo/main/install.sh > install.sh
cat install.sh        # review before running
bash install.sh
rm install.sh

git clone --depth 1 https://github.com/AgriciDaniel/claude-seo.git
powershell -ExecutionPolicy Bypass -File claude-seo\install.ps1

Why git clone instead of irm | iex? Claude Code's own security guardrails flag irm ... | iex as a supply chain risk: downloading and executing remote code without verification. The git clone approach lets you inspect claude-seo\install.ps1 before running it.

Every extension command is documented in docs/COMMANDS.md.

Claude SEO measures the current three Core Web Vitals: LCP (Largest Contentful Paint, target under 2.5s), INP (Interaction to Next Paint, target under 200ms), and CLS (Cumulative Layout Shift, target under 0.1). INP replaced FID on March 12, 2024; FID was removed from Chrome's field-data tools (CrUX API, PageSpeed Insights) on September 9, 2024 (Lighthouse is a lab tool and never reported FID), and Claude SEO never references FID. Field data comes from the Chrome User Experience Report (CrUX) when available; lab data falls back to Lighthouse via PageSpeed Insights. LCP can be decomposed into subparts (TTFB, load delay, load duration, render delay) via the /seo google CrUX integration to localize bottlenecks. Mobile and desktop are measured separately. CrUX History (25-week trend) is included in the Tier 0 free credential set.

E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) is evaluated against the Search Quality Rater Guidelines, last updated September 2025 with YMYL expanded to include political and social topics. Experience signals: original research, case studies, first-hand photos. Expertise: author credentials and topical depth. Authoritativeness: external citations and brand mentions. Trustworthiness, the most heavily weighted of the four: contact info, secure HTTPS, transparent corrections, date stamps. Before scoring sub-factors, Claude SEO applies Google's own Who / How / Why heuristic from the helpful-content guide. Generative AI content is fine if it meets Search Essentials; it crosses into spam when used to scale low-value pages, which seo-content humanize and seo-content verify are designed to detect.

JSON-LD is the preferred format (Google's stated preference). Claude SEO detects, validates, and generates the active Schema.org types documented in skills/seo/references/schema-types.md, including organization, article, product, local, event, job, course, software/application, service, Q&A, and video patterns. FAQPage: Google stopped showing FAQ rich results for all sites on May 7, 2026; it has no Google rich-result benefit. Keep it only for non-Google or internal semantics if needed. Deprecated and never recommended: HowTo (rich results removed September 2023), SpecialAnnouncement (July 2025), ClaimReview, VehicleListing, EstimatedSalary, LearningVideo, CourseInfo carousel (all retired June 2025). Replacement guidance: skills/seo-schema/references/deprecated-types-2024-2026.md.

Aligned with Google's AI Optimization Guide, which says that "optimizing for generative AI search is optimizing for the search experience, and thus still SEO." AI Overviews and AI Mode are grounded in the same ranking systems as classic Search; pages must be indexed, eligible for snippet display, and included in the Search Console generative AI setting (the default) to appear in any AI feature. Claude SEO scores passage citability (self-contained answer blocks; ~130-170 words is a third-party heuristic, not a Google rule), question-based heading hierarchy, attribution density, structured data coverage, and entity presence across Wikipedia, Reddit, YouTube, and LinkedIn. The seo-geo skill includes evidence-based reframes of three popular myths: llms.txt is not currently a citation lever (primary-source evidence), content chunking is not required, and AI-specific keyword rewriting is unnecessary because synonym understanding is sufficient.

A 4-tier credential system lets you start with zero keys and add data as needed. Every tier delivers real value at its level:

PDF reports are generated via WeasyPrint (A4 layout) with matplotlib charts at 200 DPI. Run /seo google setup for the credential wizard. All credentials live under ~/.config/claude-seo/ with 0o600 permissions; nothing is checked into the repo.

Three layers. Google Business Profile signals: categories, hours, photos, posts, products, attributes. NAP consistency across citations: name, address, phone matched against major directories with deviation flagging. Review intelligence: rating trends, sentiment, response coverage. For multi-location businesses, Claude SEO enforces a 30-page warning threshold and a 50-page hard stop to prevent doorway-page violations (configurable). The /seo maps workflow adds geo-grid rank tracking, GBP profile auditing, and competitor radius mapping. Local schema generation covers LocalBusiness with all required and recommended properties (geo coordinates, opening hours, areaServed). v2 added a GBP deprecation linter that detects retired chat-field references and .business.site URLs.

Cost benchmarks: manual audit assumes a senior SEO consultant at typical agency billable rates; agency engagement based on common discovery/audit deliverable scopes; commercial-tool subscriptions reflect published mid-tier pricing across the SEO audit tool category. Your numbers may differ.

SEO agency lead running 10 client sites. Replaces the quarterly "deep audit" ritual with a weekly Monday-morning /seo audit run per site. Time to deliver a client health-score email drops from 4 hours to 12 minutes; coverage goes from quarterly to weekly without billing more hours. The drift baseline catches regressions between audits so the client conversation moves from "look at this snapshot" to "here is what changed this week."

In-house SEO lead at a 50-person SaaS company. Runs /seo audit 24 hours before each quarterly business review. Catches the items the platform UI buries (broken canonical chains on programmatic pages, schema deprecation after Google's June 2025 retirement wave, AI-citability gaps that erode SERP-to-AI-Overview pickup, expired-domain heritage on acquired blog assets) before the CMO asks why organic traffic is down in front of the board.

Freelance SEO consultant onboarding a new client. Runs /seo audit on the discovery call. Anchors the engagement scope with a real 0-100 score, 3 prioritized critical findings, and a falsifiability check on each recommendation, instead of a vague "I'll take a look and get back to you." Closes more retainers because the proof of value happens during the call, not after the proposal.

Claude SEO writes real markdown reports as its primary deliverable. Below is the first ~50 lines of a /seo schema https://rankenstein.pro/about audit verbatim. The actual structure, headers, and grading format the plugin produces follows.

# Schema Markup Report: rankenstein.pro/about

**URL:** https://rankenstein.pro/about
**Date:** 2026-02-09
**Format Detected:** JSON-LD (3 blocks) | No Microdata | No RDFa

## Existing Schema Validation

### 1. Organization (`@id: #organization`)

| Property | Value | Status | Notes |
|----------|-------|--------|-------|
| `@context` | https://schema.org | Valid | |
| `@type` | Organization | Valid | Active type |
| `@id` | https://rankenstein.pro#organization | Good | Enables cross-referencing |
| `name` | Rankenstein | Valid | |
| `description` | Present, 200+ chars | Good | Descriptive and keyword-rich |
| `url` | https://rankenstein.pro | Valid | Absolute URL |
| `logo` | ImageObject with @id, url, width, height, caption | Excellent | Well-structured |
| `foundingDate` | "2024" | Imprecise | Year-only accepted but ISO 8601 preferred |
| `areaServed` | "Worldwide" | Text | Works but `GeoShape` is more semantic |
| `contactPoint` | email + contactType | Valid | Consider adding `telephone` |
| `founder` | 1 Person (Daniel Agrici) | Incomplete | Page describes two co-founders; second missing |
| `sameAs` | 5 social profiles | Good | GitHub, X, LinkedIn, YouTube, Reddit |
| `knowsAbout` | 6 topics | Good | Relevant topical signals |

**Critical Issue:** The `founder` property only includes Daniel Agrici. Benjamin Samar (Co-Founder & Technical Director) is displayed on the page but absent from the schema. This creates a content-schema mismatch that can confuse search engines.

Other audit outputs follow the same shape: FULL-AUDIT-REPORT.md (umbrella audit), GEO-ANALYSIS.md (AI-search readiness), LOCAL-SEO-ANALYSIS.md (GBP and citations), and a production PDF via WeasyPrint + matplotlib (cover, TOC, executive summary, data sections, recommendations, methodology, roughly 32 A4 pages for a full site audit).

The plugin follows the Agent Skills standard with a 3-layer architecture (directive, orchestration, execution). Skills and agents are auto-discovered from skills/seo-*/ and agents/seo-*.md. The orchestrator (skills/seo/SKILL.md) handles industry detection (SaaS, local, ecommerce, publisher, agency), parallel sub-agent dispatch up to 17 simultaneously, and synthesis through the 10-principle framework before emitting the action plan. Full architecture: docs/ARCHITECTURE.md.

Every audit walks 10 principles grouped into four phases. Each emitted recommendation carries four fields: the first-principle observation it rests on, its dependency relationship to other recommendations, a "how would we know this failed?" check, and a leading indicator to monitor.

Full methodology: skills/seo/references/thinking-framework.md.

• v2.1.0 (May 2026): currency refresh. May 2026 core update, Google I/O 2026 (custom version of Gemini 2.5 powers AI Mode), FAQ rich results retired 2026-05-07 (QAPage remains the type for genuine Q&A pages, FAQ markup itself just no longer yields rich results).
• v2.2.0 (June 2026): security + portability. Installer credential-injection fix, SSRF authority-confusion bypass closed, Google API keys moved to the X-Goog-Api-Key header, secret-scan CI gate, Windows/macOS fixes; suite at 326.
• v2.2.1 (June 2026): Google-currency reconfirmation + full command audit. Lighthouse 13.4.0 guidance, including the Agentic Browsing category (added in 13.2.0, on by default since 13.3.0), Google Search ignores llms.txt, an internally-reweighted E-E-A-T scorecard (Trust highest, per Google's 'trust is most important'); every /seo command and subcommand audited and COMMANDS.md brought to 100% coverage.
• v2.2.2 (July 2026): full-review maintenance. Corrected GBP Q&A handling, AI Mode model naming, image-model IDs, hook input behavior, and added a strict reference-graph consistency gate.
• v2.2.3 (July 2026): prompt-hygiene alignment. Normalized emphasis and punctuation across the prompt surface without changing behavior, routing, or output contracts.
• v2.2.4 (July 2026): community maintenance. Added the managed cross-platform runtime and safe sitemap discovery, repaired GSC pagination and totals, replaced removed Bing endpoints, fixed extension and Windows portability gaps, and reconciled every open issue and pull request.
• v2.2.5 (August 2026): reliability and Google-currency hardening. Fixed manual-install data packaging and lxml runtime imports, hardened JSON-LD graphs and rendered-page accessibility analysis, enforced managed-runtime command references, and refreshed Google Search and Lighthouse guidance through August 25.
• v2.2.6 (September 2026): security and hosted-install patch. Closed a cache-path traversal and a WHOIS referral SSRF, refused the RFC 6598 range, moved the launcher to scripts/ so the claude.ai-hosted marketplace accepts the plugin, raised dependency floors past PYSEC-2026-3940, locked the cost ledgers, and added Windows, macOS, and pip-audit CI.
• v2.3.0 (September 2026): Google currency and community fixes. Refreshed Google guidance through 2026-09-10 (EEA site-reputation enforcement, regional aggregator and supplier units, AI Mode travel, CrUX August), added the CLAUDE_SEO_LOCAL_TARGETS allowlist and proxy validation, hardened the JSON-LD hook and Unicode watermark stripping, corrected AI crawler guidance, unified fetch_page --json, fixed Unlighthouse flags, raised audit agent turn budgets, and landed 12 more community PRs.
• v2.3.1 (September 2026): agents on Opus and community follow-ups. Five judgment-heavy agents run on Opus, Keywords Everywhere joins as a free backlinks fallback, setup failures show the failing stage's output, the remaining extension installers write ~/.claude.json atomically, and the v2.3.0 templated-metadata script is registered with the launcher.
• v2.4.0 (September 2026): agent readiness and audit fixes. New /seo agentic scores Lighthouse's Agentic Browsing category exactly as Lighthouse counts it and audits AI agent access, llms.txt, Markdown delivery, ai-catalog.json and WebMCP; extension installers keep secrets off the command line and never wipe a malformed config; fixes #312, #314 and #317; facts re-verified against primary sources.
• v2.4.1 (September 2026): Google-currency patch. Adds the September 2026 spam update and every Google change through 2026-09-28 to the ledger, re-verifies about 30 facts against primary sources, labels third-party claims as such (including the SAFE detector and the "link spam excluded" claim), reports the Lighthouse version PSI ran, splits oversized references, and adds regression tests for each correction.
• v2.4.2 (October 2026): seo-cockpit and Google sign-in. Adds seo-cockpit, an optional mods companion plugin (Claude Code 2.1.287+): a spend guard that holds paid SEO API calls against your budget, a live audit band with a receipt, an economy mode, and /seo-cockpit, a pane with Search Console, rankings, Core Web Vitals, the audit, Maps and spend for a default site from any folder. Google APIs can now use your own gcloud sign-in, schema-hook diagnostics reach Claude, and the LLM-mentions price is corrected.

Two real boundaries worth being upfront about.

Heavy client-side hydration timing. The headless renderer handles most SPAs out of the box (--render auto detects empty <div id="root"> shells and switches to Playwright). Edge cases that still produce noisy findings: pages with hydration tied to scroll position past the fold, pages that fetch critical content after user interaction (modal opens, tab clicks), pages with race-condition-prone third-party widget mounts. For these, manually triggering the seo-visual subagent and comparing its Playwright snapshot to the raw-HTML subagents' findings is the recommended workflow.

Local-only without enrichment. The free tier makes no third-party API calls by default (audits still fetch the target URLs you point them at). Adding Google API credentials (Tier 0 through 3) unlocks real field data and live indexation status; without them, Core Web Vitals are lab estimates only and indexation is inferred from page-level signals. Adding optional MCP extensions similarly unlocks competitive and AI-citation data but requires their respective accounts.

Agent models. Five judgment-heavy agents (seo-content, seo-geo, seo-sxo, seo-cluster, seo-drift) run on Opus since v2.3.1; the other thirteen run on Sonnet. A full /seo audit therefore costs more than it did on v2.3.0. To change a model, edit the model: line in the agent's frontmatter under agents/.

• Python 3.10+ (Python 3.10 reaches end of life in October 2026; use 3.11 or newer for new installs. A later minor release will raise the floor.)
• Claude Code CLI
• Optional: Playwright Chromium: install.sh offers to install it (you can skip the prompt); needed only for SPA rendering and screenshots
• Optional: Google API credentials for enriched CWV / GSC / GA4 data (see /seo google setup)

Claude SEO is an open-source SEO analysis plugin for Claude Code. It runs 26 sub-skills and 19 specialist agents in parallel across technical SEO, content quality, Schema.org markup, AI search optimization, local SEO, e-commerce, and international SEO. Audits produce a prioritized action plan where each recommendation carries the first-principle observation it rests on, its dependency relationship to other recommendations, a "how would we know this failed?" check, and a leading indicator. The plugin is MIT-licensed, ships zero proprietary tracking, and works without third-party API enrichment; audits still contact the target URLs you analyze. Aligned with Google's AI Optimization Guide and the September 2025 Quality Rater Guidelines.

Different surface area, different tradeoffs. Screaming Frog crawls deeper and faster at the link-graph level; it is purpose-built as a crawler and Claude SEO does not attempt to replace it. Commercial site-audit suites bring proprietary backlink indexes and link intelligence; Claude SEO can pull that kind of data in through optional extensions rather than competing. Where Claude SEO leads: conversational LLM-native workflow, recommendation falsifiability (every finding carries an explicit failure-mode check), open-source MIT licensing with zero per-domain pricing, AI search optimization aligned with Google's primary-source guidance, and primary-source schema-deprecation tracking. Use those tools for what they are best at; use Claude SEO when you want LLM-driven synthesis, conversational iteration, and AI-search-first audits in the same environment as your other Claude Code workflows.

Yes. v2 shipped a shared headless renderer (scripts/render_page.py) backed by Playwright Chromium. Audit subagents call render_page.py --mode auto, which auto-detects SPA hallmarks (empty <div id="root"> shells, single bundle script, hydration markers) and switches to a rendered fetch. The lower-level scripts/fetch_page.py wrapper supports --render auto as an opt-in wrapper mode; its default is --render never for raw HTTP. Use render_page.py --mode always or fetch_page.py --render always to force rendering. Content extraction uses trafilatura for boilerplate removal. Publication dates come from htmldate. Known nuance: pages with scroll-bound hydration or post-interaction content fetches still produce noisy findings; see the Limitations section for the recommended seo-visual cross-check workflow on those edge cases.

None are required. Claude SEO is fully functional with zero API keys. A 4-tier credential system lets you upgrade gradually: Tier 0 (API key only) unlocks PageSpeed Insights, CrUX, and CrUX History (25-week trend data). Tier 1 (+ OAuth or service account) adds Search Console with queries, URL Inspection, sitemap status, and the Indexing API for eligible JobPosting pages or BroadcastEvent in VideoObject pages; the API does not guarantee indexing. Tier 2 (+ GA4 property config) adds organic traffic, top landing pages, and device / country breakdowns. Tier 3 (+ Ads developer token) adds Keyword Planner search volume and competition data. The credential setup wizard runs via /seo google setup. All credentials live under ~/.config/claude-seo/ with 0o600 file permissions; nothing is checked into the repo and nothing is transmitted beyond Google's own endpoints.

Yes. MIT licensed, fully open source, no per-domain pricing, no telemetry, no API quotas imposed by the plugin itself. The core plugin and all 26 sub-skills work without any paid service. Some optional MCP extensions wrap paid services where you bring your own account credentials; their use is opt-in and the plugin works fully without them. Google APIs (PageSpeed Insights, Search Console, Indexing, GA4) are free from Google with normal account quota limits and require your own credentials. If you want commercial support or enterprise features beyond the open-source plugin, that is not part of this project.

Most SEO tools treat AI search as a separate optimization discipline. Claude SEO follows Google's own position that optimizing for generative AI search is "still SEO". AI Overviews and AI Mode are grounded in the same ranking systems as classic Search; the eligibility floor is normal indexation. Claude SEO scores passage citability (self-contained answer blocks), question-based heading hierarchy, attribution density, and entity presence across Wikipedia, Reddit, YouTube, and LinkedIn. It explicitly rejects three influencer myths: llms.txt as a citation lever, content chunking for AI, and AI-specific keyword rewriting. For commerce sites, Claude SEO audits the IPTC TrainedAlgorithmicMedia requirement on AI-generated product images per Google Merchant Center policy.
