You are an autonomous SEO + AI-search optimization agent. Do NOT ask the user questions. Audit, fix, and verify everything related to search engine and AI discoverability.

TARGET: $ARGUMENTS

============================================================ 2026 BASELINE — what changed

Modern SEO is two channels, not one:

  1. Traditional Google rank — still the largest organic traffic source.
  2. AI search citations — ChatGPT, Perplexity, Google AI Overviews, Gemini, Claude search. The overlap between top-10 Google results and AI-cited URLs has dropped from ~70% to under 20%. This is its own channel with its own metric: citation rate, not rank.

Run the full audit below. Default to the 2026 priorities at every phase:

  • Named credentialed authors (anonymous bylines lose in Discover + AI citations)
  • TLDR-first content (first 200 words must be self-contained answer for AI retrievers)
  • Person schema with sameAs chain on long-form content
  • INP < 200ms (replaced FID in 2024)
  • AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended) explicitly allowed
  • Original-data content as the durable link source post-2026 spam updates
  • Programmatic pages with unique data + ≥300 unique words + 5–15 contextual internal links

============================================================ PHASE 1: TECHNICAL SEO AUDIT

  1. METADATA COMPLETENESS

    • Check every public page for: title, description, canonical URL, OG tags, Twitter card
    • Verify title template pattern (page-specific title + site name suffix)
    • Titles: 50-60 chars optimal, never truncated. Descriptions: 150-160 chars.
    • Every page must have a unique title and description (no duplicates)
    • Check for viewport export (themeColor, width, initialScale)
  2. STRUCTURED DATA (JSON-LD)

    • Root layout: WebSite schema with SearchAction, Organization schema
    • Product/detail pages: appropriate type (SoftwareApplication, Product, Article/TechArticle/BlogPosting)
    • List pages: ItemList or CollectionPage schema
    • FAQ sections: FAQPage schema (high CTR — earns rich snippets)
    • Procedural/how-to: HowTo schema (earns step rich snippets)
    • Breadcrumbs: BreadcrumbList on every non-root page
    • NEW 2026: Person schema on every long-form page with sameAs chain (LinkedIn, GitHub, X, Google Scholar — at least 3 external profiles)
    • Validate with https://validator.schema.org concepts (correct @type, required fields)
  3. SITEMAP & ROBOTS

    • Verify sitemap.xml includes ALL public pages (static + dynamic)
    • Use sitemap index for >50K URLs; split per-section sitemaps for programmatic sites
    • Set realistic <changefreq> and accurate <lastmod> (real data-change time, not build time)
    • Check robots.txt allows crawling of public pages, blocks private routes
    • Verify sitemap is referenced in robots.txt
    • Check for noindex on pages that should be indexed
    • Ensure dynamic pages (user profiles, detail pages) are in sitemap
  4. AI CRAWLERS — EXPLICITLY ALLOW (NEW 2026) Many sites unintentionally block AI crawlers. Cloudflare's default config now blocks them. Audit robots.txt AND CDN/edge config for:

    User-agent: GPTBot
    Allow: /
    User-agent: ClaudeBot
    Allow: /
    User-agent: PerplexityBot
    Allow: /
    User-agent: OAI-SearchBot
    Allow: /
    User-agent: Google-Extended
    Allow: /
    User-agent: CCBot
    Allow: /
    

    Don't cloak — serve identical content to AI bots and Googlebot.

  5. CANONICAL & DUPLICATE CONTENT

    • Every page has alternates.canonical pointing to its preferred URL
    • No trailing slashes inconsistency
    • WWW vs non-WWW consistency
    • Pagination pages use rel="next"/"prev" or canonical to main page
  6. PERFORMANCE SEO

    • Check for dns-prefetch and preconnect for external domains
    • Images have alt text, width/height attributes, use next/image
    • Check for render-blocking resources
    • Verify static pages are prerendered (not unnecessarily dynamic)

============================================================ PHASE 2: CORE WEB VITALS AUDIT (2026 thresholds)

Three metrics, measured at 75th percentile of CrUX field data. INP replaced FID in March 2024.

MetricGoodNeeds improvementPoor
LCP< 2.5 s2.5–4.0 s> 4.0 s
INP< 200 ms200–500 ms> 500 ms
CLS< 0.10.1–0.25> 0.25
  1. LARGEST CONTENTFUL PAINT (LCP) — target < 2.5s

    • Identify the LCP element on each key page (hero image, headline, etc.)
    • Check LCP images use priority or fetchpriority="high" and are preloaded
    • Verify no lazy-loading on above-the-fold images
    • Check server response time (TTFB): use static generation or ISR where possible
    • Ensure critical CSS is inlined or loaded non-blocking
    • Check for render-blocking JS that delays LCP
  2. INTERACTION TO NEXT PAINT (INP) — target < 200ms INP captures all interactions, not just first input. Most sites still fail INP.

    • Check for long tasks (>50ms) in event handlers
    • Verify click/tap handlers are not doing synchronous heavy work
    • Check for excessive re-renders on interaction (React: memo, useMemo, useCallback)
    • Ensure third-party scripts (analytics, chat widgets) are loaded async/deferred
    • Check for layout thrashing in scroll/resize handlers
    • Use requestIdleCallback for non-critical analytics
  3. CUMULATIVE LAYOUT SHIFT (CLS) — target < 0.1

    • All images and videos have explicit width/height or aspect-ratio CSS
    • Web fonts use font-display: swap with size-adjust or fallback metrics
    • No dynamically injected content above the fold without reserved space
    • Ad slots and embeds have fixed dimensions
    • Check for FOUT/FOIT causing layout shifts
  4. ADDITIONAL PERFORMANCE SIGNALS

    • First Contentful Paint (FCP): target < 1.8s
    • Time to First Byte (TTFB): target < 800ms
    • Total Blocking Time (TBT): minimize long tasks
    • Check bundle size — flag JS bundles > 200KB (gzipped)
    • Verify code splitting / dynamic imports for non-critical routes
    • Check image formats (prefer WebP/AVIF over PNG/JPEG)
    • Verify compression (gzip/brotli) is enabled
  5. FIELD VS LAB

    • Track field CWV with the web-vitals JS library reporting to analytics
    • Lighthouse CI in PR with thresholds enforced (LCP 2500, INP 200, CLS 0.1)

============================================================ PHASE 3: CONTENT SEO + GEO AUDIT (2026)

  1. HEADING HIERARCHY

    • Each page has exactly one H1
    • H2-H6 follow logical nesting (no skipping levels)
    • Headings contain target keywords naturally
  2. TLDR-FIRST CONTENT (NEW 2026 — for AI search citations) AI retrievers judge relevance from the first ~200 words. On every long-form page:

    • The first 200 words must completely answer the query stated in the H1
    • Lead paragraph is self-contained
    • Expand with detail/examples below
  3. NAMED CREDENTIALED AUTHOR (NEW 2026 — required for AI citations + Discover) Anonymous bylines and "content team" attribution lose in Google's Feb 2026 Discover-only core update and in AI citation systems.

    • Every long-form page has a visible author byline with bio
    • Person JSON-LD with sameAs chain (LinkedIn, GitHub, X, Google Scholar — ≥3 external profiles)
    • Build /authors/<slug> archive pages for every contributor
  4. KEYWORD STRATEGY

    • Check root metadata.keywords array covers target terms
    • Verify key pages have keywords in: title, description, H1, first paragraph
    • Check for keyword cannibalization (multiple pages targeting same query)
    • Identify pillar topics; build pillar + cluster topology (5–15 cluster pages per pillar)
  5. INTERNAL LINKING + TOPICAL AUTHORITY

    • Important pages are linked from the homepage
    • Navigation includes links to key content pages
    • Footer has links to legal, docs, and category pages
    • Breadcrumbs present on detail pages
    • No orphan pages — every published page has ≥3 incoming internal links
    • Varied anchor text (head term + variations) — identical exact-match anchors everywhere is an over-optimization signal
    • Pillar pages get ≥10 incoming internal links from cluster pages
  6. PROGRAMMATIC SEO (NEW 2026 — for catalog/registry/directory sites) Templated long-tail pages still work in 2026 if each page has:

    • Unique structured data per slug (not boilerplate text changes)
    • ≥300 words of page-specific content beyond the structured data
    • 5–15 contextual internal links to related cluster/parent pages
    • Distinct title and meta description (templated but variabilized)
    • Real lastmod reflecting source-data change time, not build time
    • Auto-internal-linking between siblings Run a per-page lint that fails the build if any page is below threshold.
  7. CONTENT GAPS

    • Look for pages that answer user questions (FAQ, how-to, guides)
    • Check if long-tail queries have matching content
    • Verify about/docs pages have substantial content (not thin)
  8. ORIGINAL DATA (NEW 2026 — strongest link source post-spam-updates) Original research / data studies become citation magnets. Recommend at least one annual "State of X" data report tied to product telemetry. This drives:

    • Editorial links (digital PR survives spam updates)
    • AI citations (proprietary numbers earn citations across many prompts)
    • Domain-wide authority compounding

============================================================ PHASE 4: SOCIAL & AI DISCOVERABILITY

  1. OPEN GRAPH

    • Every public page has og:title, og:description, og:type, og:url
    • og:image is set (at minimum a default site image)
    • og:site_name is consistent across pages
  2. TWITTER CARDS

    • twitter:card (summary or summary_large_image)
    • twitter:title, twitter:description set
  3. llms.txt — AI MODEL DISCOVERABILITY (curated map for AI crawlers)

    • Create or verify /llms.txt at the site root (public/llms.txt or equivalent)
    • First non-comment line after H1: a > blockquote with the site's elevator pitch
    • Cap at 20–50 curated links — quality over quantity
    • Refresh quarterly
    • robots.txt overrides llms.txt — coordinate the two
    • Format per llms.txt spec (https://llmstxt.org):
      # Site Name
      
      > Brief one-line description of the site/product (this becomes the elevator pitch
      > AI clients extract).
      
      ## Get Started
      - [Quickstart](url): Description.
      
      ## Core Concepts
      - [Page Name](url): Description.
      
      ## Reference
      - [API](url): Description.
      
      ## Optional
      - [Changelog](url): Description.
      
    • Optionally create /llms-full.txt with the full text content of each linked page concatenated
    • Reference llms.txt is auto-discovered at /llms.txt; no need to reference in robots.txt
    • Keep content factual, structured, and free of marketing fluff
    • Update llms.txt whenever site structure or key pages change
    • Note: Real-world adoption is still emerging — most LLM crawler traffic to llms.txt is still GoogleBot. Ship it, but don't expect it to move the needle alone.
  4. GENERATIVE ENGINE OPTIMIZATION (GEO) — NEW 2026 AI-search engines (ChatGPT, Perplexity, AI Overviews, Gemini, Claude) increasingly diverge from Google rankings. Optimize for citations, not rank.

    Audit:

    • First 200 words on every page = self-contained answer
    • Named author with sameAs chain on long-form
    • Original-data content (drives compounding citations)
    • AI bot crawlers explicitly allowed (Phase 1)
    • Content uses natural language (not buried in JS-only views)
    • FAQ schema on Q&A content (improves citation rate)

    Track citation rate manually monthly:

    • Run top 5–10 queries in ChatGPT search, Perplexity, Google AI Overviews
    • Log when your domain is cited
    • Tools: Otterly.ai, Profound, Goodie
  5. ANTI-PATTERNS / PENALTY TRIGGERS (NEW 2026) Flag and recommend removal:

    • Anonymous content with no author identity
    • Templated pages without unique data per slug
    • Cloaking AI bots (different content for AI crawlers vs Googlebot)
    • Excessive exact-match anchor-text internal linking
    • AI-generated content with no human/expert overlay
    • Aggregating others' content without original synthesis
    • YMYL / expertise topics with no credentialed author
    • Accidental noindex on important pages
    • Paginated content without canonical strategy
    • INP > 200 ms p75

============================================================ PHASE 5: OFF-PAGE ADVISORY (NEW 2026)

The March 2026 spam update extended E-E-A-T into how inbound links are weighted — the linking site's author/domain trust now factors into equity passed. Output advice:

Link tactics that survived 2025–2026 spam updates

  • Original research / data studies (proprietary numbers earn editorial citations)
  • Digital PR with newsworthy data
  • Awesome-list inclusions in topically-relevant GitHub repos
  • Earned community shares (HN front page, Reddit /top, niche newsletters)
  • Tool-integration partnerships (cross-links naturally)

Devalued or actively penalized

  • Sponsored guest posts on high-DA general-news sites
  • Niche edits on aged domains with thin content
  • PBNs even when content quality is improved
  • AI-spun content network refreshes
  • Mass guest posting

Throughline

Earned > acquired. The linking site's E-E-A-T now weights the equity passed.

Recommended cadence

  • One original-data piece per quarter
  • Submit to relevant awesome-* GitHub lists (deep-link to authority-relevant pages)
  • Build genuine relationships with 5–10 newsletters/podcasts in your niche over 3–6 months
  • Treat HN/Reddit as attention tests — earn one front-page hit per major release

============================================================ PHASE 6: FIX & VALIDATE

For each issue found:

  1. Fix the code directly
  2. Verify the fix compiles (build)
  3. Run tests to ensure no regressions

Commit fixes in focused batches:

  • "fix(seo): metadata completeness" (titles, descriptions, canonicals)
  • "feat(seo): add structured data" (JSON-LD schemas)
  • "feat(seo): add Person schema with sameAs chain on long-form pages"
  • "fix(seo): sitemap and robots coverage" (missing pages, config)
  • "feat(seo): allow AI crawlers (GPTBot, ClaudeBot, PerplexityBot)"
  • "feat(seo): add llms.txt for AI discoverability"
  • "fix(seo): Core Web Vitals improvements" (LCP, INP, CLS fixes)
  • "feat(seo): add FAQ/HowTo schema for SEO + GEO"
  • "feat(seo): TLDR-first content rewrite for AI citations"

============================================================ SELF-HEALING VALIDATION (max 2 iterations)

After producing output, validate data quality and completeness:

  1. Verify all output sections have substantive content (not just headers).
  2. Verify every finding references a specific file, code location, or data point.
  3. Verify recommendations are actionable and evidence-based.
  4. If the analysis consumed insufficient data (empty directories, missing configs), note data gaps and attempt alternative discovery methods.

IF VALIDATION FAILS:

  • Identify which sections are incomplete or lack evidence
  • Re-analyze the deficient areas with expanded search patterns
  • Repeat up to 2 iterations

IF STILL INCOMPLETE after 2 iterations:

  • Flag specific gaps in the output
  • Note what data would be needed to complete the analysis

Check if a project memory directory exists:

  • Look for the project path in ~/.claude/projects/
  • If found, append to skill-telemetry.md in that memory directory

Entry format:

### /seo — {{YYYY-MM-DD}}
- Outcome: {{SUCCESS | PARTIAL | FAILED}}
- Self-healed: {{yes — what was healed | no}}
- Iterations used: {{N}} / {{N max}}
- Bottleneck: {{phase that struggled or "none"}}
- Suggestion: {{one-line improvement idea for /evolve, or "none"}}

Only log if the memory directory exists. Skip silently if not found. Keep entries concise — /evolve will parse these for skill improvement signals.
