## 1. What GEO and AEO actually are

**GEO (Generative Engine Optimization)** is the practice of structuring a
website's content, metadata and crawler access so that generative AI engines
include it in their training, retrieval and answer-synthesis pipelines.

**AEO (Answer Engine Optimization)** is the practice of writing and marking up
content so that answer engines (Google AI Overviews, Perplexity, ChatGPT
Search, Bing Copilot) cite it as a direct answer to a user's question.

GEO and AEO overlap with classic SEO but optimize for a different surface:
the answer itself, not the blue-link list. The unit of success is a citation
or an inline reference, not a click.

## 2. The signals AI engines actually use

In order of impact for getting cited:

1. **Crawler access.** GPTBot, OAI-SearchBot, Google-Extended, ClaudeBot,
   PerplexityBot, Applebot-Extended, CCBot and friends must be allowed in
   robots.txt. Blocking them removes you from the retrieval pool entirely.
2. **Answerable content.** Each page should answer one clear question in the
   first 1–2 sentences, with a self-contained paragraph an LLM can quote
   without context.
3. **Structured data.** FAQPage, HowTo, Product, Article, Organization,
   BreadcrumbList JSON-LD. AI engines lean heavily on schema to disambiguate
   entities and pick citations.
4. **Entity clarity.** A consistent name, sameAs links, an Organization
   schema, and an /about page that names the company, founders, location and
   topic authority.
5. **llms.txt.** A markdown file at /llms.txt that tells AI crawlers what
   your site is and where to read more. Follows the spec at llmstxt.org.
6. **Semantic HTML.** One `<h1>`, ordered `<h2>`/`<h3>`, real lists, real
   tables. AI extractors fail silently on `<div>` soup.
7. **Freshness and dates.** `datePublished` and `dateModified` in schema and
   visible on the page. Stale content gets demoted in answer engines.
8. **Citations and outbound links.** Linking to authoritative sources
   improves your own citability — answer engines prefer pages that already
   look like research.

## 3. llms.txt — what it is, what it is not

`/llms.txt` is a markdown file at the site root, proposed at llmstxt.org. It
is a *table of contents* for LLMs — not a robots file, not a sitemap, not a
content dump.

Required: one H1 (site name). Recommended: a blockquote summary, then `##`
sections with markdown link lists in the form `- [Title](/path): description`.

Common sections: Core, Docs, Pages, Blog, Tools, Optional. Keep links
public-only — never list admin, auth, or per-user routes. Keep the file
flat: no nested headings beyond H2, no HTML.

Pair `/llms.txt` (the index) with `/llms-full.txt` (this file) when you have
long-form content worth quoting in full.

## 4. robots.txt for AI

A correct AI-aware robots.txt names each AI crawler explicitly with `Allow:
/`, even when the default `User-agent: *` already allows them — some bots
only check their own block. Common bots to name:

GPTBot, ChatGPT-User, OAI-SearchBot, Google-Extended, GoogleOther, Googlebot,
Applebot, Applebot-Extended, ClaudeBot, Claude-Web, anthropic-ai,
PerplexityBot, Perplexity-User, CCBot, cohere-ai, Bytespider, Amazonbot,
DuckAssistBot, YouBot, Meta-ExternalAgent, FacebookBot, Diffbot, PetalBot,
MistralAI-User.

End with `Sitemap: https://yourdomain.com/sitemap.xml`.

## 5. Structured data that AI engines actually read

- **Organization** + **WebSite** sitewide on the root layout.
- **FAQPage** on any page with Q&A content (including the home page).
- **HowTo** on tutorials and step-by-step pages.
- **Product** + **AggregateRating** + **Review** on product/landing pages
  with social proof.
- **Article** + `datePublished` + `dateModified` + `author` on blog posts.
- **BreadcrumbList** on deep routes.
- **SpeakableSpecification** on pages you want voice assistants to read.
- **SoftwareApplication** for tools and SaaS.

Keep schema in sync with what's visible — invented reviews or fake ratings
get the page penalized in AI surfaces.

## 6. The OptimAIze scoring model (0–100)

Five weighted pillars:

1. **Crawler access (20 pts)** — robots.txt allowances for the top 20 AI
   crawlers, plus reachability of llms.txt, sitemap.xml and ai-plugin.json.
2. **Content answerability (25 pts)** — semantic HTML, headings, lead
   paragraphs, presence of Q&A blocks, average paragraph quotability.
3. **Structured data (20 pts)** — schema coverage, validity, completeness of
   required fields, entity consistency across pages.
4. **Entity and authority (15 pts)** — Organization schema, sameAs,
   /about/contact presence, outbound citation links.
5. **Technical hygiene (20 pts)** — meta tags, canonical, hreflang, status
   codes, render-without-JS check, freshness signals.

The output is a numeric score, a per-pillar breakdown, a prioritized issue
list, and a set of downloadable fix files (`llms.txt`, `robots.txt`,
`schema.jsonld`, `sitemap.xml`, `ai-plugin.json`, `faq.jsonld`).

## 7. Frequently asked questions

**Q: What is the difference between SEO, GEO and AEO?**
A: SEO optimizes for the ranked list of links on a search results page. GEO
optimizes for inclusion in generative AI training and retrieval (ChatGPT,
Gemini, Claude). AEO optimizes for being cited as the answer on answer
engines (Google AI Overviews, Perplexity, Bing Copilot). The three overlap
but reward different on-page work.

**Q: Will blocking GPTBot help or hurt me?**
A: Blocking GPTBot removes you from OpenAI's training corpus and, depending
on the bot, from ChatGPT Search retrieval. For most sites that want
distribution and citations, the cost of being invisible outweighs the
benefit of withholding training data. Block only if you have a legal or
licensing reason.

**Q: Do I need /llms.txt if I already have sitemap.xml?**
A: They serve different purposes. sitemap.xml is a list of every URL for
crawlers to index. /llms.txt is a curated, human-readable map of your most
important pages, written for LLMs that have a tight context budget. Ship
both.

**Q: How often should I re-run a GEO/AEO audit?**
A: Monthly for stable sites, weekly for sites that publish frequently or
that just shipped major changes. OptimAIze offers continuous monitoring
that diffs scores over time and alerts on regressions.

**Q: Does OptimAIze submit my site to AI engines?**
A: No engine offers a "submit" endpoint the way Google does. OptimAIze
makes your site *discoverable* and *citable* — the engines find it through
their own crawl and retrieval. The fastest signal is usually fixing
crawler access plus shipping structured data; citations start appearing
within days to weeks.

**Q: Is OptimAIze free?**
A: Yes — scans are free, with no signup required for the basic report.
Paid tiers add continuous monitoring, bulk audits, white-label PDF reports
and API access. See https://optimaize.app/pricing.
