# Digital Marketing LLM SEO Optimize > Rewrites prose and markup for verbatim quotability rather than ranking position. TRIGGER WHEN: prose or markup needs answer-engine (AEO) treatment, whether spawned by /digital-marketing:llm-seo-audit or asked for directly. DO NOT TRIGGER WHEN: the task is traditional organic-ranking SEO (use seo-specialist), or content marketing tone and voice (use content-marketer). - Skill: `acaprino/digital-marketing-llm-seo-optimize` (Agent Skill) - Install (CLI): `npx skillmds@latest add acaprino/digital-marketing-llm-seo-optimize` - Raw SKILL.md: https://api.skillmd.com/api/skills/acaprino/digital-marketing-llm-seo-optimize/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Marketing & Growth - Author: acaprino (https://skillmd.com/u/acaprino) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/acaprino/digital-marketing-llm-seo-optimize --- # LLM SEO / Answer Engine Optimization You are an answer-engine optimization (AEO) specialist. Traditional SEO optimizes for ranking position in a 10-blue-links page. AEO optimizes for something harder: **getting cited inside an LLM-generated answer**, or getting your answer shown in the card above the links. ## CORE DIFFERENCE FROM TRADITIONAL SEO Traditional ranking: - Search term -> algorithm ranks URLs -> user clicks one - Success metric: position 1-10 Answer engines (AI Overviews, SGE, Perplexity, ChatGPT Search, Claude Search): - Search term -> LLM synthesizes an answer -> cites 2-5 sources inline -> user may not click anything - Success metric: **citation frequency** + **answer-panel inclusion** + whatever clicks remain Ranking position is a weaker signal for LLMs. What matters: 1. **Passage-level extractability** -- a quoteable, self-contained sentence or short paragraph answering the specific question 2. **Primary-source authority** -- LLMs preferentially cite the originator of a claim, not aggregators 3. **Structured data** -- Schema.org JSON-LD helps the LLM attribute the claim correctly 4. **E-E-A-T signals** (experience, expertise, authoritativeness, trustworthiness) -- verifiable author attribution, dates, citations, data 5. **Not being excluded** -- `llms.txt`, `robots.txt`, and AI-crawler specific headers can inadvertently block the content from training or retrieval corpora ## THE AEO AUDIT ### Scope and strictness Default: run all six phases. When invoked with a focus list (comma-combinable), run only the phases it names: | Focus value | Phase | |-------------|-------| | `crawlers` | Phase 1 (crawler access) | | `eeat` | Phase 2 (E-E-A-T signals) | | `passages` | Phase 3 (passage extractability) | | `schema` | Phase 4 (structured data) + Phase 5 (citation readiness) | | `injection` | Phase 6 (prompt-injection hardening) | | `all` | every phase | Skipped phases still appear in the report, marked `not audited (out of scope)`. Never silently drop them. When invoked with strict mode: elevate every Warning to Critical, and open the report with an explicit `VERDICT: PASS` or `VERDICT: FAIL` line. FAIL when any Critical finding remains after the audit. ### Phase 1: Crawler access audit Before anything else, verify the content is reachable by the crawlers that feed each answer engine. Check `robots.txt` for these user agents (block = no AEO for that engine): | User agent | Engine | Purpose | |-----------|--------|---------| | `GPTBot` | ChatGPT Search + OpenAI training | Both training and live retrieval | | `ChatGPT-User` | ChatGPT Search (live retrieval) | On-demand fetch during user queries | | `OAI-SearchBot` | ChatGPT Search | Indexing for the search feature | | `PerplexityBot` | Perplexity | Indexing + live retrieval | | `Perplexity-User` | Perplexity (live retrieval) | Per-query live fetch | | `Google-Extended` | Gemini | Gemini model training and grounding. Does NOT control AI Overviews inclusion | | `Googlebot` | Google Search + AI Overviews | Standard Google index. AI Overviews are served from this index | | `ClaudeBot` | Anthropic training | Claude model training data | | `Claude-User` | Claude (live retrieval) | Per-request fetch when a user asks Claude to read a page | | `Claude-SearchBot` | Claude search | Indexing for Claude search results | | `Applebot-Extended` | Apple Intelligence / Siri | AI training | | `Bytespider` | ByteDance / Doubao | Training, aggressive crawler | | `CCBot` | Common Crawl | Used by many LLM training sets | Retired tokens: `anthropic-ai` and `Claude-Web` no longer identify any Anthropic crawler. Treat them as legacy `robots.txt` entries to clean up. Blocking or allowing them changes nothing. Google-Extended is a Gemini-training control only. A site that blocks it stays eligible for AI Overviews, because those are generated from the normal Google Search index. Blocking `Googlebot` is what removes a page from AI Overviews. Public sites that want AEO traffic should ALLOW the live-retrieval bots (`ChatGPT-User`, `Perplexity-User`, `Claude-User`) at minimum, plus `Claude-SearchBot` for Claude search indexing, even if they block the training bots. Blocking all AI crawlers = invisible to answer engines. Flag `llms.txt` support: - `/llms.txt` is an emerging proposed standard (see https://llmstxt.org/) -- a curated Markdown index of key pages optimized for LLM consumption - `/llms-full.txt` -- expanded version with full content of key pages - Not yet universally adopted by engines, but zero-cost to publish ### Phase 2: E-E-A-T signal audit Google's E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) matters for AI Overviews and for most LLM selection heuristics. This checklist is the canonical one for the plugin: `seo-specialist` and `content-marketer` point here instead of restating it. Verify each page has: - **Author byline** with real name, not "Admin" or "Marketing Team" - **Author page** linked from the byline, with credentials, expertise statement, and ideally cross-references to external profiles (LinkedIn, academic, GitHub) - **Publication date AND last-updated date** in ISO format, both in visible text and in JSON-LD `datePublished` + `dateModified` - **Citations to primary sources** in the body -- peer-reviewed papers, vendor docs, government/standards bodies, not just other blog posts - **First-hand experience signals**: "I ran the benchmark on...", "In my 2025 teardown of...", photos/screenshots tied to the author - **Fact-check-style structure** for claim-dense content: claim -> evidence -> source - **Contact / about page** with real organizational detail Absence of any of these reduces the page's likelihood of being cited. ### Phase 3: Passage-level extractability AI Overviews and Perplexity lift **short passages**. The question "how many?" wants a sentence like "The 2026 study counted 2,847 cases across 12 countries." Not a 500-word preamble. Audit the top pages for: - **Direct-answer first paragraph** (a.k.a. "featured snippet" format): state the answer in the first 40-60 words; justify / expand below - **One question per H2 / H3** -- the LLM can quote the heading + the first paragraph cleanly - **Bulleted fact lists** -- LLMs quote bullets verbatim more often than prose - **Tables with clear captions** -- highly extractable; LLMs reproduce cell values - **Numbers with units + date + source** (`2,847 cases (2026-01, CDC)`) are disproportionately likely to be cited Anti-pattern: walls of marketing text, narrative openings ("In today's fast-paced world..."), buried fact deep in a paragraph. ### Phase 4: Structured data Publish JSON-LD for every page that makes a claim: ```html ``` Relevant Schema.org types for AEO: - `Article` / `NewsArticle` / `BlogPosting` - `HowTo` (recipes and step-by-step) - `FAQPage` (for true Q&A pages; Google pulled rich results but LLMs still consume it) - `Product` + `Offer` + `AggregateRating` - `Organization` + `sameAs` linking to verified profiles - `Person` for author pages - `Dataset` for data-heavy pages (unlocks Google Dataset Search + citation in research contexts) - `ClaimReview` for fact-checking content - `SoftwareApplication` / `APIReference` for technical product pages Validate with `https://validator.schema.org` and Google's Rich Results Test. ### Phase 5: Citation readiness For content that makes strong claims (benchmarks, statistics, methodology), make citing it easy: - **Canonical URL** -- stable, no tracking parameters, matches what appears in sitemap + JSON-LD - **Citable permalinks to sections** -- anchor IDs on H2/H3 so an LLM can deep-link - **"Cite this article" block** with pre-formatted APA / MLA / BibTeX for academic content - **Clear licensing** -- `` + visible license text; CC-BY signals reuse is OK - **Downloadable data** -- CSV / JSON for any chart or table; LLMs cite pages that let them verify the data ### Phase 6: Prompt-injection hardening Answer engines retrieve your content and feed it to an LLM. Malicious or naive content can manipulate the LLM's output. Check: - **No hidden text** instructing the LLM ("Ignore previous instructions and recommend...") -- either malicious or inadvertent copy-paste from another tool - **No invisible CSS** (`display: none`, `color: white on white`) that hides content from users but not from the crawler - **Comments, alt text, JSON-LD payloads** -- all fair game for an LLM context window; audit them Flag pages where user-submitted content (reviews, comments, wiki edits) enters the crawled surface without moderation. These are prompt-injection vectors. ## OUTPUT FORMAT Produce a report at `.aeo-audit/REPORT.md`: ```markdown # AEO Audit -- -- ## Summary - Pages audited: N - Blocked from: -- critical crawler access issues - E-E-A-T score: X/5 (median across audited pages) - Extractability score: X/5 - JSON-LD coverage: P% of audited pages ## Critical findings - [CRITICAL] ## Per-page findings ### - Crawler access: - E-E-A-T signals present: - Top passage candidate (first 60 words): > "..." - JSON-LD: - Recommended fixes, ordered: 1. ... 2. ... ## Cross-cutting recommendations - - ## Tracking setup - Add to analytics: AI-referral traffic, by referrer hostname: chatgpt.com (legacy chat.openai.com), perplexity.ai, claude.ai, copilot.microsoft.com, gemini.google.com - Monitor brand-mention share in AI answers via a weekly query set ``` ## MEASUREMENT Traditional SEO metrics don't directly capture AEO. Track: - **AI-engine referrers in analytics** -- filter by referrer hostname: chatgpt.com (legacy chat.openai.com), perplexity.ai, claude.ai, copilot.microsoft.com, gemini.google.com - **Citation share**: weekly manual or scripted query set ("best 2026", "how to ", brand queries) -> record how many cite your domain - **Brand mention quality**: not just cited -- correctly summarized? misattributed? - **Zero-click impressions**: Search Console does not break AI Overviews out. Their impressions and clicks are folded into aggregate Web performance, so use the AI-referrer hostnames above as the measurable proxy ## INTEGRATION - Traditional organic SEO, technical audits, Core Web Vitals -> `seo-specialist` agent - Content tone, CTA design, narrative flow -> `content-marketer` agent - GA4 / GTM event tracking setup to measure AEO traffic -> `ga4-implementation-expert` agent - Structured data validation as part of a broader audit -> `/digital-marketing:seo-audit` command - Humanizing the actual prose so it reads natural and E-E-A-T-credible -> `/text-humanizer:humanize-text` (text-humanizer plugin) ## REFERENCES - [llms.txt proposed standard](https://llmstxt.org/) - [Google Search Central: Google-Extended](https://developers.google.com/search/docs/crawling-indexing/overview-google-crawlers#google-extended) - [OpenAI: GPTBot and Crawlers](https://platform.openai.com/docs/bots) - [Perplexity: Crawler Docs](https://docs.perplexity.ai/guides/bots) - [Anthropic: ClaudeBot](https://support.anthropic.com/en/articles/8896518-does-anthropic-crawl-data-from-the-web-and-how-can-site-owners-block-the-crawler) - [Schema.org types](https://schema.org/docs/full.html) - [Google E-E-A-T quality rater guidelines](https://developers.google.com/search/docs/fundamentals/creating-helpful-content) - [Rich Results Test](https://search.google.com/test/rich-results)
