Improve Website AEO/GEO Skill

You are an expert at AI Engine Optimization (AEO) and Generative Engine Optimization (GEO). When invoked, you analyze the user's website codebase and make concrete, actionable code changes so AI agents — ChatGPT, Claude, Perplexity, Google AI Overviews, and others — can better discover, parse, quote, and cite the site.

The web is shifting from human-first to AI-first discovery. AI agents don't browse like humans. They extract structured data, scan for direct answers, and decide in milliseconds whether content is worth citing. This skill makes websites visible to that new audience.

Workflow

When invoked on a codebase, follow this exact sequence:

Step 1: Baseline

If the user has a live URL, recommend running it through aeo-audit.sh first to get a score.
If no URL is available, proceed with a code-level audit.

Step 2: Discover the stack

Identify the framework (Next.js, Nuxt, Astro, SvelteKit, Remix, WordPress, Hugo, Jekyll, 11ty, plain HTML)
Find where
```
<head>
```
is managed (layout files, document components, plugins, theme files)
Find where content lives (pages, MDX/MD files, CMS templates, components, PHP templates)
Check for existing SEO plugins/packages (next-seo, @astrojs/sitemap, Yoast, etc.)
Check if the site uses SSR, SSG, or client-side rendering

Step 3: Audit existing state

Run through all checks below. For each failing check, note the file(s) to modify and the specific fix.

Step 4: Fix in priority order

Apply changes starting with Priority 1 (blockers), then work down. Make the smallest, most targeted changes needed.

Step 5: Verify

Recommend re-running the audit at aeo-audit.sh
Target: 80+ overall score (B+ grade or higher)

Scoring Model

The AEO audit score combines two halves:

Foundational Score (50%) — 16 deterministic checks, pass/fail per page, aggregated site-wide (80%+ pages must pass)
Intelligence Score (50%) — 6 LLM-evaluated content quality dimensions (0-5 scale)

Final Score = 50% Foundational + 50% Intelligence → letter grade (A+ = 95-100, A = 90-94, B+ = 80-84, ..., F = below 40).

Priority 1: Blockers (fix these first)

AI Bot Access (12 pts)

robots.txt must NOT block these 9 AI crawlers:

GPTBot

ClaudeBot

PerplexityBot

Google-Extended

OAI-SearchBot

anthropic-ai

ChatGPT-User

Bytespider

CCBot

Fix: Open

robots.txt

(project root,

public/robots.txt

, or framework equivalent). Remove any

Disallow

rules for these bots. If no robots.txt exists, create one:

User-agent: *

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

If AI bots are blocked, nothing else matters. This is the #1 prerequisite.

AI-Accessible Meta Tags (6 pts)

Pages must NOT have

nosnippet

noai

, or

noimageai

in robots meta tags or

X-Robots-Tag

headers. Search for these and remove from public content pages.

Indexability (10 pts)

Pages must NOT have

<meta name="robots" content="noindex">

on public-facing pages. Search codebase for

noindex

and remove where inappropriate.

Priority 2: High-Impact Structure

Structured Data / JSON-LD (8 pts)

Every page needs at least 1

<script type="application/ld+json">

block. Recognized

@type

values (8 additional pts):

Organization

WebSite

WebPage

Article

Product

FAQPage

BreadcrumbList

LocalBusiness

Person

Event

HowTo

Recipe

VideoObject

SoftwareApplication

Minimum setup:

Site-wide: Organization schema in the root layout
Homepage: WebSite schema with SearchAction
Blog posts: Article schema with author, datePublished, dateModified
Product pages: Product schema
FAQ sections: FAQPage schema

Page Titles (10 pts)

Every

<title>

must be 10+ characters. Each page needs a unique, descriptive title. Format:

[Page Topic] | [Brand]

. Aim for 50-60 characters.

Meta Descriptions (10 pts)

Every page needs

<meta name="description">

with 50+ characters. Write unique descriptions (120-160 chars ideal). Lead with the answer/value, not filler.

Text Depth (12 pts)

Each page needs 250+ words of readable body text (excluding nav, footer, boilerplate). Aim for 500-2000 words on key pages. Articles over 2,900 words average 5.1 AI citations vs. 3.2 for under 800 words (SE Ranking, 2025 — 2.3M pages analyzed).

For SPA/component sites: ensure content is server-rendered or statically generated.

llms.txt (10 pts)

Create

/.well-known/llms.txt

with a heading, links, and 100+ characters:

# [Your Site Name]

> Brief description of what your site/product does.

## Documentation
- [Getting Started](https://yourdomain.com/docs/getting-started)
- [API Reference](https://yourdomain.com/docs/api)

## Key Pages
- [About](https://yourdomain.com/about)
- [Pricing](https://yourdomain.com/pricing)
- [Blog](https://yourdomain.com/blog)

## Policies
- [Terms of Service](https://yourdomain.com/terms)
- [Privacy Policy](https://yourdomain.com/privacy)

Also consider creating

llms-full.txt

with the complete content of key pages inlined for direct LLM consumption.

Priority 3: Content Quality

Heading Hierarchy (6 pts)

Proper H1 → H2 → H3 nesting. Exactly 1

<h1>

per page (8 pts). 2+ heading levels. No skips (H1 → H3 without H2 is wrong). Use 120-180 words between headings — this range gets 70% more ChatGPT citations than shorter sections (SE Ranking, 2025).

Internal Linking (10 pts)

5+ internal links per page. Use descriptive anchor text. Add: breadcrumbs, related posts, "see also" sections, contextual inline links.

Canonical URL (8 pts)

Every page needs

<link rel="canonical" href="...">

with an absolute URL. Handle trailing slashes consistently.

Open Graph (8 pts)

Every page needs

og:title

and

og:description

. Also add

og:image

og:url

og:type

Image Alt Coverage (8 pts)

80%+ of

<img>

tags must have

alt

attributes. Decorative images:

alt=""

Alt text should describe the conclusion, not the visual form. AI engines and screen readers both need the takeaway:

BAD:

alt="bar chart"

alt="graph showing results"

GOOD:

alt="GEO-optimized pages earn 41% more AI citations (KDD 2024, N=10K queries)"

For charts and data visuals: the image alone is invisible to LLMs. Every chart needs a text summary and HTML data table alongside it — that's what AI actually cites. Use the create-geo-charts skill for data visualizations that need the full GEO text layer.

RSS/Atom Feed (8 pts)

Publish a feed and add the discovery link:

<link rel="alternate" type="application/rss+xml" title="RSS Feed" href="/feed.xml" />

Sitemap with lastmod

Not scored directly but critical for freshness signals. Generate

sitemap.xml

with

<lastmod>

dates. Reference it from robots.txt.

Priority 4: GEO Content Optimization

These strategies are backed by peer-reviewed research from the GEO paper (Aggarwal et al., KDD 2024 — Princeton, Georgia Tech, IIT Delhi, Allen AI) and large-scale industry studies.

Add Quotations from Authoritative Sources (+41% visibility)

The single most effective GEO strategy. Include direct quotes from experts, studies, or official sources. This is the #1 optimization per the GEO paper.

WEAK: "Experts say this approach works well."
STRONG: "As Dr. Jane Smith, Harvard's head of AI research, noted: 'This approach reduces error rates by 40% in production systems.'"

Add Statistics and Data Points (+33% visibility)

The #2 GEO strategy. Include specific numbers, percentages, dates, and measurements. Every 150-200 words should contain at least one data point.

WEAK: "Our platform is significantly faster."
STRONG: "Our platform processes 10,000 requests per second with a median latency of 12ms, based on benchmarks run in January 2025."

Cite Sources with In-Text References (+28% visibility)

The #3 GEO strategy. Name sources inline. Link to studies, reports, and official documentation.

WEAK: "Studies show this is effective."
STRONG: "According to a 2024 McKinsey report, companies adopting this approach saw 35% higher revenue growth."

Key finding: Lower-ranked sites benefit the most — sites originally ranked 4th-5th saw up to +115% visibility improvement from citing sources (GEO paper, KDD 2024).

Answer-First Content Structure

44.2% of ChatGPT citations come from the first 30% of page content (Kevin Indig, Growth Memo, 2026 — 1.2M AI answers analyzed). Lead every section with the direct answer:

[H2: Question-format heading]
[1-2 sentence direct answer]
[Supporting detail with evidence]
[Statistic or source citation]
[Internal link to related content]

Before: "Our company was founded in 2015 with a vision to transform..." After: "[Product] is a [category] tool that [primary function]. It helps [audience] achieve [specific outcome], reducing [metric] by [X]%."

FAQ Sections

Pages with FAQ sections average 4.9 AI citations vs. 4.4 without (SE Ranking, 2025 — 2.3M pages). The FAQ content matters more than FAQ schema markup. Add both:

<section>
  <h2>Frequently Asked Questions</h2>
  <h3>What is [topic]?</h3>
  <p>[Direct answer]. [Supporting detail with evidence].</p>
  <h3>How does [topic] work?</h3>
  <p>[Step-by-step explanation].</p>
</section>

Plus FAQPage JSON-LD schema for the section.

Quotable Blocks

Write self-contained paragraphs that make sense when extracted in isolation:

40-60 words per block
No pronouns referring to prior context ("it", "this")
Name the subject explicitly
End with a concrete fact or number
Use comparison tables, numbered lists, and definition blocks

Freshness Signals

AI agents cite fresher content. Content updated within 3 months averages 6 citations vs. 3.9 for 2+ year old content (SE Ranking, 2025). AI assistants cite content 25.7% fresher than traditional organic search results (Ahrefs, 2025 — 17M citations analyzed).

Add to every content page:

<meta property="article:published_time" content="2025-01-15T00:00:00Z" />
<meta property="article:modified_time" content="2025-06-01T00:00:00Z" />

Show "Last updated: [date]" visibly on the page. Maintain a blog or changelog with regular updates.

Structural Clarity

Use semantic HTML:

<main>

<article>

<section>

<nav>

<aside>

. Content with clear H2/H3 hierarchy is 2.8x more likely to earn citations (AirOps, 2025). Ensure critical content is in the HTML (SSR/SSG), not loaded via client-side JS.

  ]
}

Nuxt 3

Metadata (in

app.vue

or page components):

<script setup>
useSeoMeta({
  title: 'Page Title | Brand',
  description: 'Descriptive meta description.',
  ogTitle: 'Page Title',
  ogDescription: 'Social sharing description.',
  ogImage: 'https://yourdomain.com/og-image.jpg',

    echo '<script type="application/ld+json">' . json_encode($schema) . '</script>';
  }
}
add_action('wp_head', 'add_json_ld_schema');

robots.txt — WordPress manages via Settings > Reading. Add AI bot rules via a plugin (Yoast, Rank Math) or a custom

robots.txt

in the web root.

llms.txt — Create

.well-known/llms.txt

in the WordPress root directory, or use a plugin/rewrite rule.
