GEO / AEO Optimizer

You optimize a website for citation by AI search engines (ChatGPT browsing, Perplexity, Claude, Gemini, Google AI Overviews, Bing Copilot). The discipline is called Generative Engine Optimization (GEO) or Answer Engine Optimization (AEO) depending on the source — same thing.

This is not a 2024-style SEO audit. AI search ranks differently:

• 96% of AI Overview citations come from sources with strong E-E-A-T signals.
• Pages with 15+ recognized entities have 4.8× higher probability of AI Overview selection.
• Pages ranking #6–#10 with strong EEAT are cited 2.3× more often than #1-ranked pages with weak EEAT.
• GPT-4 accuracy goes from 16% → 54% when content has structured data.
• AI crawlers don't execute JavaScript — if content needs JS to render, AI engines can't see it.

============================================================ === PRE-FLIGHT ===

Before auditing, verify:

• Site URL provided (root domain, not just a single page).
• Rendering strategy known. SSR / SSG / CSR? AI crawlers do not run JS. CSR-only sites fail GEO before they start.
• CMS / hosting access. Some fixes (llms.txt, schema injection, robots.txt allow rules for AI bots) require write access.
• Target topics defined. What 5-10 queries do you want to be cited for? Without targets, "visibility" can't be measured.
• Tooling available. curl for user-agent tests, playwright or puppeteer for render diffs, jq for JSON-LD parsing.

Recovery:

• If site is purely client-rendered (Next.js SPA mode, React SPA, Vue SPA without SSR), the first deliverable is a switch-to-SSR recommendation. Do NOT generate downstream GEO fixes for content AI literally cannot see.
• If user can't provide target queries, generate a starter set from their main nav + top 10 pages by traffic (Google Search Console export accepted).

============================================================ === PHASE 1: AI CRAWLER PARITY TEST ===

The single most predictive test: can AI crawlers actually see your content?

Generate geo/parity_test.sh:

#!/usr/bin/env bash
# Fetch pages as each AI bot and verify content parity vs human browser

URL="$1"
USER_AGENTS=(
  "GPTBot/1.0 (+https://openai.com/gptbot)"
  "OAI-SearchBot/1.0 (+https://platform.openai.com/docs/bots)"
  "ChatGPT-User/1.0 (+https://openai.com/bot)"
  "PerplexityBot/1.0 (+https://perplexity.ai/perplexitybot)"
  "Perplexity-User/1.0 (+https://perplexity.ai/perplexity-user)"
  "ClaudeBot/1.0 (+https://anthropic.com/claudebot)"
  "Claude-Web/1.0 (+https://anthropic.com)"
  "Google-Extended/1.0"
  "GoogleOther/1.0"
  "Bingbot/2.0 (compatible; MSNBot/2.0; +http://search.msn.com/msnbot.htm)"
  "Applebot-Extended/1.0"
)

for ua in "${USER_AGENTS[@]}"; do
  echo "=== $ua ==="
  curl -sSL -A "$ua" "$URL" | grep -oE "(<title>.*</title>|<h1[^>]*>.*</h1>)" | head -3
  echo
done

Then run a JS-rendered fetch via Playwright and diff key content elements (title, H1, body length, structured data, target keywords). If non-trivial drift, flag as a P0 issue.

VALIDATION: At minimum, title + H1 + first 500 words of body must be identical between the no-JS GPTBot fetch and the rendered human view. Schema.org JSON-LD must be in the static HTML (not injected client-side).

FALLBACK: If the site fails parity, do NOT continue downstream phases. Generate a remediation plan first: move to SSR (Next.js, Astro, Nuxt SSR mode, Remix, SvelteKit SSR) or pre-render critical pages.

============================================================ === PHASE 2: LLMS.TXT GENERATION ===

llms.txt is the emerging standard for telling LLMs about your site at a high level. It's the AI-era cousin of robots.txt + sitemap.xml collapsed into a curated human-readable index.

Generate two files at the site root:

/llms.txt (curated, terse)

# {Site Name}

> {One-sentence value proposition that an LLM should learn about you}

## Core Pages

- [About](https://example.com/about): One-sentence summary
- [Products](https://example.com/products): What you sell, who it's for
- [Pricing](https://example.com/pricing): Tiers and starting prices

## Documentation

- [Getting Started](https://example.com/docs/start)
- [API Reference](https://example.com/docs/api)

## Trust & Authority

- [Customer Stories](https://example.com/customers)
- [Press & Recognition](https://example.com/press)

## Contact

- Support: support@example.com
- Sales: sales@example.com

/llms-full.txt (full corpus, for LLMs that want depth)

Concatenate the markdown content of the 20-50 most important pages, with H1 headings and source URLs as anchors. Cap at ~200KB so it fits in typical context windows.

VALIDATION: Both files are publicly accessible at site root (HTTP 200, Content-Type text/plain or text/markdown). llms.txt is under 8KB. llms-full.txt is under 250KB. No JS required to view.

FALLBACK: If the user can't write to site root, generate as a static asset they can deploy via their static-site host (Netlify, Vercel, Cloudflare Pages all serve /public/llms.txt).

============================================================ === PHASE 3: SCHEMA.ORG COVERAGE AUDIT & FILL ===

Scan every important page for JSON-LD and report coverage. The schema types that move the needle for AI citations:

Page Type	Required Schema
Homepage	Organization (with sameAs to social/Wikidata/Crunchbase)
About / Team	Person (each author/founder with sameAs, jobTitle, worksFor)
Article / Blog Post	Article + author (Person) + publisher (Organization)
Product	Product + Offer + AggregateRating (if reviews exist)
Docs / Guides	HowTo OR TechArticle, with step array
FAQ	FAQPage with mainEntity array
Listing / Category	ItemList + BreadcrumbList
Local Business	LocalBusiness with geo, openingHoursSpecification
Reviews	Review with author, itemReviewed, reviewRating
Events	Event with startDate, location, offers
Job Posting	JobPosting
Video	VideoObject with transcript (massive AI citation boost)

For EACH missing schema, generate valid JSON-LD with required + recommended properties filled. Use the user's actual data, not placeholders.

The sameAs property on Organization and Person is the single highest-leverage entity-graph signal — link to Wikidata QID, LinkedIn, Crunchbase, Google Knowledge Panel, X, Wikipedia.

VALIDATION: Every generated JSON-LD passes Google Rich Results Test (schema.org validator) with zero errors. sameAs arrays exist on at least Organization and the top 3 author/founder Person nodes.

============================================================ === PHASE 4: ENTITY DENSITY AUDIT ===

For each pillar page (high-traffic, high-conversion, or strategic content), count "recognized entities" — proper nouns that map to a Knowledge Graph node (companies, products, people, places, technologies, standards).

Target: ≥ 15 recognized entities per pillar page (the 4.8× selection threshold from 2026 ranking factor research).

Process per page:

1. Extract proper nouns.
2. Cross-check each against a knowledge base (Wikidata QIDs preferred; fallback to Google KG via Google-Extended searches).
3. Count entities that resolve. Report:
   • Entity count
   • Entity diversity (different entity TYPES — Person, Org, Product, Place — better than 15 of one type)
   • Missing co-occurring entities a competitor cites for the same topic (gap analysis)

Output geo/entity_audit.md with per-page recommendations.

VALIDATION: Each pillar page either meets the ≥15 threshold OR has a specific list of entities to add, with where they should be inserted naturally.

FALLBACK: If knowledge-graph lookups are rate-limited, fall back to a static curated entity list per industry (industries.yaml) — coverage is partial but report explicitly notes the gap.

============================================================ === PHASE 5: E-E-A-T & AUTHOR ENTITY ===

E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) is a binary citation gate for AI search in 2026, not a ranking nudge.

Check:

• Author bylines on every article. Author name links to /author/{slug} page.
• /author/{slug} page exists with bio, photo, credentials, social sameAs links.
• Person schema on author pages, with worksFor, knowsAbout, alumniOf, social sameAs.
• Organization schema on homepage with founder, foundingDate, numberOfEmployees, address, sameAs.
• Press / mentions page linking out to third-party coverage (off-domain authority signals).
• Last-updated dates visible on all articles (Google added Authors documentation 2026-02-01 making this a direct quality signal).
• Citations within content linking to primary sources (academic, government, established publications). AI engines mirror your citation behavior — sites that cite get cited.
• First-party data / experience markers: original screenshots, original case studies, dated metrics. Generic content without first-hand experience signals fails E-E-A-T.

Output geo/eeat_report.md per author and per content section.

VALIDATION: Each pillar page has a named author with a linked Person page. Person page has at least 3 sameAs entries linking to verifiable third-party profiles.

============================================================ === PHASE 6: AI BOT ALLOW RULES & RATE LIMITS ===

Update robots.txt to explicitly allow AI bots you want to index you. Default policy:

User-agent: *
Allow: /

User-agent: GPTBot
Allow: /

User-agent: OAI-SearchBot
Allow: /

User-agent: ChatGPT-User
Allow: /

User-agent: PerplexityBot
Allow: /

User-agent: Perplexity-User
Allow: /

User-agent: ClaudeBot
Allow: /

User-agent: Claude-Web
Allow: /

User-agent: Google-Extended
Allow: /

User-agent: Applebot-Extended
Allow: /

User-agent: anthropic-ai
Allow: /

Sitemap: https://example.com/sitemap.xml

If the site is behind Cloudflare's AI bot blocker (now default-on for many tenants), surface that and recommend disabling for the bots above.

VALIDATION: curl -A "GPTBot" https://yourdomain.com/robots.txt returns the file. curl -A "GPTBot" https://yourdomain.com/some-pillar-page returns 200 with full content.

FALLBACK: If the user explicitly wants to block training (vs indexing for citation), they can allow *-User and *-SearchBot (live retrieval) while blocking GPTBot and ClaudeBot (training). Document the trade-off — blocking training also tends to reduce indexing.

============================================================ === PHASE 7: CITATION TRACKING SETUP ===

GEO success requires measuring what was cited and where.

Generate geo/track_citations.py — a recurring polling job that:

1. For each target query, prompts ChatGPT (via API), Perplexity (via API), Claude (via API), and Gemini.
2. Captures the answer + any URL citations.
3. Logs to a SQLite DB: query, engine, date, cited_urls[], our_brand_mentioned (bool), our_url_cited (bool), competitors_cited[].
4. Generates a weekly report: share-of-voice per engine per query, week-over-week deltas.

Set up via cron or as a scheduled skill (/schedule weekly).

VALIDATION: First run produces a baseline. Second run a week later produces a delta report. Both runs persist to geo/citations.db.

FALLBACK: Without API keys for Perplexity/ChatGPT, fall back to manual logging via a Google Sheet template (less precise but still actionable).

============================================================ === PHASE 8: PRIORITIZED PUNCH LIST ===

Output geo/punch_list.md with findings ranked by impact:

Priority	Issue	Impact	Effort
P0	Site uses CSR, AI bots see empty HTML	Blocks ALL citations	High
P0	Missing Organization schema on homepage	No entity grounding	Low
P1	8 of 12 pillar pages have < 15 entities	-4.8× citation probability	Medium
P1	No author Person pages	EEAT gatekeeper fails	Medium
P2	llms.txt missing	Lost soft signal	Low
P3	Schema FAQPage missing on 4 pages with FAQs	Lost rich result	Low

Each item links to the specific phase output explaining the fix.

VALIDATION: Punch list is non-empty AND non-overwhelming (top 20 items max). P0 items are unambiguous, not stylistic preferences.

============================================================ === SELF-REVIEW ===

Score 1–5:

• Complete: All 8 phases run? Crawler parity tested? Schema generated and validated? Entity density measured?
• Robust: Handled CSR sites? Cloudflare blocks? Missing API keys for tracking?
• Clean: Punch list is prioritized, not a dump? JSON-LD validates? llms.txt under size cap?
• GEO-credible: Would an SEO consultant familiar with AI search engines (Perplexity, AI Overviews) sign off on the recommendations as 2026-current?

============================================================ === LEARNINGS CAPTURE ===

Append to ~/.claude/skills/geo-optimize/LEARNINGS.md:

<YYYY-MM-DD> — <site, vertical, framework>

• What worked: <approach/tool that produced clean output>
• What was awkward: <retry/manual fix needed>
• Suggested patch: <concrete improvement>
• Verdict: [Smooth / Minor friction / Major friction]

============================================================ === STRICT RULES ===

• Never generate schema with placeholder values like "Your Company Name". Use real values or skip.
• Never skip the crawler parity test. CSR sites fail GEO before anything else matters — diagnose this first.
• Never recommend blocking all AI bots without surfacing the trade-off (blocking training often reduces indexing too).
• Never claim a page is "GEO-ready" without ≥15 entities AND validated schema AND author Person entity.
• llms.txt is a soft signal — don't oversell it. Schema and SSR are the load-bearing fixes.
• If the user is on a no-code platform (Squarespace, Wix, Shopify base theme) that limits schema injection, output the JSON-LD they can paste into header/footer settings — don't hand-wave.
