seobeast-audit

Full-site SEO audit via 6 parallel specialist subagents. Runs on any public URL with no setup.

Usage

/seobeast-audit https://example.com

Orchestration

When invoked with a URL, execute this sequence:

Step 1 — Prefetch shared data (do this once, before spawning subagents)

Use WebFetch to retrieve:

• The page HTML at <url>
• <origin>/robots.txt
• <origin>/llms.txt

Pass this prefetched data to all subagents to avoid duplicate fetches.

Step 2 — Spawn 6 subagents in parallel using the Task tool

Each subagent receives:

• The URL to audit
• The prefetched HTML, robots.txt content, and llms.txt content
• A specific domain to focus on (defined in agents/*.md)

Subagents:

1. seo-technical — Crawlability, indexability, URL structure, canonical, redirects, robots.txt
2. seo-content — Word count, H1/H2 usage, E-E-A-T signals, thin content, readability
3. seo-performance — Render-blocking resources, lazy loading, image dimensions, CWV hints
4. seo-security — HTTPS, HSTS, CSP, X-Frame-Options, security headers
5. seo-schema — JSON-LD detection, Organization schema, Article/Product schema, breadcrumbs
6. seo-aeo — AI crawler access (GPTBot, ClaudeBot, PerplexityBot), llms.txt, passage citability

Step 3 — Aggregate results and output the unified report

Output Format

After all subagents complete, output exactly this format:

Score Bar Rendering

Use Unicode block characters for the score bars:

• █ for filled segments
• ░ for empty segments
• 10 segments total per bar
• Filled = round(score / 10)

Overall score bar is 20 segments wide.

Priority Definitions

• Critical: Blocks indexing, causes penalties, or directly harms rankings. Fix immediately.

  • meta noindex on a non-staging page
  • robots.txt blocking all crawlers
  • GPTBot blocked in robots.txt
  • No HTTPS (HTTP page)
  • No H1 tag
  • No title tag

• High: Significant ranking or visibility impact. Fix within 1 week.

  • Missing meta description
  • Missing og:image
  • No JSON-LD structured data
  • Render-blocking scripts (>3)
  • Images missing alt text (>30%)

• Medium: Optimization opportunities. Fix within 1 month.

  • Missing llms.txt
  • Missing HSTS header
  • Title too long or too short
  • No sitemap referenced
  • Missing author attribution

Scoring Methodology

Calculate a composite 0–100 score using these category weights:

Category	Weight
Core SEO	14%
Performance	12%
Content	10%
Technical SEO	7%
Crawlability	7%
Links	6%
Security	6%
Structured Data	6%
AEO Readiness	5%
Images	5%
E-E-A-T	5%
Social	3%
Mobile	3%
Accessibility	3%
URL Structure	2%
Redirects	2%
JavaScript	1%
Internationalization	1%
HTML Validation	1%
Legal	1%

Error Handling

Scenario	Action
URL unreachable	Report error, do not guess content
robots.txt returns 404	Note it, continue audit without robots data
Subagent fails	Report partial results, flag the failed domain
Non-HTML response	Report content type, skip HTML-dependent checks

AEO Section Notes

The AEO (AI Engine Optimization) section is a first-class audit pillar:

• Check robots.txt for GPTBot, ClaudeBot, anthropic-ai, PerplexityBot, OAI-SearchBot
• Check for /llms.txt presence and basic structure (H1 title + ## sections)
• Evaluate whether content paragraphs are 80–200 words (optimal for AI citation)
• Check if sections begin with direct answers (not "In this article, we will...")
• Flag SSR vs CSR: pages requiring JS execution may be invisible to AI crawlers

CWV Reference (2026)

Current thresholds per Google:

• LCP: Good <2.5s, Needs Improvement 2.5–4s, Poor >4s
• INP: Good <200ms, Needs Improvement 200–500ms, Poor >500ms (replaced FID March 2024)
• CLS: Good <0.1, Needs Improvement 0.1–0.25, Poor >0.25

Do not reference FID. INP is the sole interactivity metric. FID was removed from all Google tools in September 2024.

Schema Notes

• FAQPage schema: Google removed rich results for commercial sites in August 2023. Retain existing FAQPage for LLM citation benefit only. Do not recommend adding new FAQPage for commercial sites.
• HowTo schema: Deprecated by Google in September 2023. Never recommend.
• FAQ and HowTo rich results still exist for government and healthcare sites only.
