@Canonry/aeo-audit

The most comprehensive open-source technical AEO (Answer Engine Optimization) audit tool. Scores any website across 16 ranking factors that decide whether AI answer engines (ChatGPT, Perplexity, Gemini, Claude) will cite your content.

• Score any URL across 16 AEO factors: structured data, llms.txt, E-E-A-T, extractability, snippet eligibility, and more. Scoring
• Audit a whole site from its sitemap; per-page findings roll up into ranked fixes. Sitemap mode
• Audit built HTML offline in CI: a next export / dist / out directory, no network. Static output
• Detect the platform / CMS / framework: WordPress, Webflow, Shopify, Next.js, Vercel. Platform detection
• Opt in to Lighthouse, geographic, and agent-skill factors. Optional factors
• text, json, markdown, and agent output with CI-friendly exit codes. CLI reference
• Agent-native output: a versioned schemaVersion, a slim --format agent decision, ranked structured fixes, and stable finding codes so integrations key on codes, not prose. API
• Use as a library (API) or from Claude Code via the /aeo skill (skill).

Audit your site

npx @ainyc/aeo-audit https://example.com

Prints a scored report. Common variations:

# Every page in the sitemap, site-wide issues only
npx @ainyc/aeo-audit https://example.com --sitemap --top-issues

# JSON for CI/CD (exit 1 when score < 70)
npx @ainyc/aeo-audit https://example.com --format json

# A built directory, offline
npx @ainyc/aeo-audit ./out --base-url https://example.com

Full flag and mode reference: docs/cli.md.

From your AI coding agent

The package ships a Claude Code / ClawHub skill. Install it, then:

/aeo audit https://example.com

Modes: audit, fix, schema, llms.txt, monitor. See the skill guide.

Guard CI against regressions (GitHub Action)

Drop the AEO Audit Guard action into any pipeline to fail a PR when its AEO score drops, a page stops auditing, or a new structural defect appears — measured against a committed baseline. It builds your site, audits the HTML offline (no deploy, no secrets), and posts a sticky PR comment with the per-factor diff.

# .github/workflows/aeo.yml
on:
  pull_request: { branches: [main] }
permissions:
  contents: read
  pull-requests: write          # for the sticky comment
jobs:
  aeo-gate:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: pnpm/action-setup@v4
        with: { version: 9 }
      - uses: actions/setup-node@v4   # the engine needs Node >= 20
        with: { node-version: 20, cache: pnpm }
      - uses: Canonry/aeo-audit-action@v4
        with:
          build-command: "pnpm install --frozen-lockfile && pnpm run build"
          target: "./out"                      # your built HTML (Next export / Astro dist / Hugo public)
          base-url: "https://www.example.com"
          baseline-path: ".aeo/baseline.default.json"

The first run has no baseline, so it passes and tells you to seed one (npx @ainyc/aeo-audit@4 ./out --base-url https://www.example.com --format json > .aeo/baseline.default.json, then commit it). See the aeo-audit-action README for url/sitemap modes, baseline strategies, monorepos, tolerances, and every input.
