How to Get Your Content Indexed by LLMs

Learn the most effective methods to ensure your content is discoverable by Large Language Models (LLMs) and AI-powered search engines. This guide covers both IndexNow and Bing's URL Submission API, helping you choose the best approach for your needs.

Why LLM Indexing Matters

Getting your content indexed by LLMs is crucial because:

  • LLMs use search engine indexes to find and reference content
  • Indexed content appears in AI-powered search results
  • Your content can be cited by LLMs in their responses
  • Faster indexing means quicker visibility in AI systems

IndexNow: The Modern Approach

IndexNow is a protocol supported by multiple search engines that allows instant URL submission:

Advantages

  • Supported by multiple search engines (Bing, Yandex, etc.)
  • Simple implementation with a single API key
  • Real-time URL submission
  • Lower server load on search engines

Implementation Steps

  1. Generate an API key from IndexNow
  2. Host the key file at your domain root
  3. Submit URLs when content changes
  4. Monitor indexing status
async function submitToIndexNow(urls) {
    const response = await fetch('https://api.indexnow.org/v1.0/submit', {
        method: 'POST',
        headers: {
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({
            host: 'www.yourdomain.com',
            key: 'your-api-key',
            keyLocation: 'https://www.yourdomain.com/your-key.txt',
            urlList: urls
        })
    });
    return response.json();
}

Bing URL Submission API: Direct Integration

Bing's URL Submission API provides direct control over URL submission to Bing's index:

Advantages

  • Direct integration with Bing's index
  • Higher daily submission limits (up to 10,000 URLs)
  • Detailed submission tracking
  • Priority processing for important content

Implementation Steps

  1. Get your API key from Bing Webmaster Tools
  2. Implement the API in your content management system
  3. Submit URLs in batches
  4. Monitor submission status
async function submitToBing(urls) {
    const response = await fetch('https://ssl.bing.com/webmaster/api.svc/json/SubmitUrlbatch', {
        method: 'POST',
        headers: {
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({
            siteUrl: 'https://www.yourdomain.com',
            urlList: urls
        })
    });
    return response.json();
}

  • Ensure mobile-friendly design
  • Maintain consistent content structure
  • Monitor indexing status regularly
  • Implement both methods for maximum coverage

Implementation Tips

Content Management Systems

  • WordPress: Use official IndexNow plugin
  • Custom CMS: Implement both APIs
  • Static Sites: Add to build process

Error Handling

  • Log submission errors
  • Monitor rate limits
