How Will Web Pages Be Found by AI? — llms.txt and JSON-LD Guide

Since 2024, the AI world has radically changed. ChatGPT is no longer just a chatbot — it’s an assistant that browses the web and brings you the latest information. Perplexity, Google Gemini, Claude, and dozens of other AI models are constantly crawling and analyzing websites to answer users’ questions.

But how well do these systems understand your website? When a user asks “daily boat tour in Bodrum,” can ChatGPT recommend your business? Does Perplexity accurately present the pricing information on your site? The answer to these questions lies in the concept of AI discoverability.

What is AI Discoverability?

AI discoverability is the degree to which a website is findable, understandable, and usable by AI systems. While classic SEO (Search Engine Optimization) targets Google, AI discoverability targets LLMs (Large Language Models) like ChatGPT, Perplexity, and Gemini.

The difference is: when Google indexes a page, it scans all HTML, follows links, and determines results with a complex ranking algorithm. LLMs work quite differently:

Natural Language Understanding: LLMs “read” your page like a human and grasp its meaning. But they still need structured data.
Context Integrity: Information on your site needs to be consistent. If you write “10:00-18:00” on one page and “09:00-19:00” on another, the AI gets confused.
Summarization: LLMs extract information from your site and present it to the user as a summary. llms.txt lets you control this summary.

llms.txt — Give LLMs a Guide to Your Site

llms.txt is a text file added to the root directory of your website. Just as robots.txt guides search engines, llms.txt provides AI models with a summary of your site’s content.

What Does It Look Like?

Here’s a real llms.txt example:

# Simge Yachting | Bodrum & Yalıkavak Luxury Yacht Charter

Create an llms.txt file in your website’s root directory (public/ folder)
Start with business name, short description, and contact information
List all your services
List all important pages with links
Deploy and check at yoursite.com/llms.txt

JSON-LD Structured Data — Give Context to AI

If llms.txt is your site’s table of contents, JSON-LD structured data is your site’s detailed identity card. It’s the most modern way to add structured data to web pages using Schema.org standards.

Most Critical JSON-LD Schemas

1. LocalBusiness

Contains your business name, address, phone, working hours, rating, and social media links. ChatGPT uses this data when asked about a business.

{
  "@context": "https://schema.org",
  "@type": "LocalBusiness",
  "name": "Simge Yachting",
  "telephone": "+90******",
  "address": {
    "@type": "PostalAddress",
    "addressLocality": "Yalıkavak",
    "addressRegion": "Bodrum",
    "addressCountry": "TR"
  },
  "aggregateRating": {
    "@type": "AggregateRating",
    "ratingValue": "4.7",
    "reviewCount": "40",
    "bestRating": "5"
  },
  "priceRange": "€€€€"
}

2. FAQPage

Presents frequently asked questions in structured format. Perplexity and ChatGPT use FAQ schema to answer users directly.

{
  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": [
    {
      "@type": "Question",
      "name": "How long does the daily tour last?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Our tours last 8 hours from 10:00 to 18:00."
      }
    }
  ]
}

3. BreadcrumbList

Shows the page’s position within the site. Helps AI understand the page’s context.

{
  "@context": "https://schema.org",
  "@type": "BreadcrumbList",
  "itemListElement": [
    { "@type": "ListItem", "position": 1, "name": "Home", "item": "https://simgeyachting.com" },
    { "@type": "ListItem", "position": 2, "name": "Daily Tours", "item": "https://simgeyachting.com/gunluk-tekne-turlari" }
  ]
}
