How to Prepare Your Site: Technical SEO for AI Search

published on 17 September 2025

As artificial intelligence continues to reshape how information is discovered online, SEO strategies must evolve to match. With AI-driven platforms like ChatGPT, Perplexity, Claude, and Gemini rising in prominence, understanding how to optimize your website for large language models (LLMs) is no longer optional - it's a necessity.

If you're someone looking to boost your site's visibility in the emerging AI search ecosystem, this article will guide you through actionable technical SEO techniques tailored for AI crawlers. From managing JavaScript-heavy websites to implementing schema markup and optimizing site speed, we’ll equip you with tools to future-proof your site for AI-driven discovery.

Let’s dive in.

The Rise of AI in Search: Why It Matters

AI-powered search engines and platforms work differently compared to traditional search engines like Google or Bing. While traditional engines rely heavily on crawling and indexing through sitemaps and structured content, LLM-based platforms extract and process information to generate conversational answers.

This shift means that your site’s technical setup - how information is structured, how accessible it is, and how quickly it loads - plays a more significant role than ever in determining whether your content is discoverable.

If your website isn’t optimized for AI crawlers, you risk being left out of this new search paradigm entirely.

To ensure your site thrives in the AI-driven search ecosystem, here are the most critical areas to focus on:

1. Avoid JavaScript Overload

A visually stunning, JavaScript-heavy website may impress human visitors, but it can be a major roadblock for AI crawlers.

Why JavaScript Can Be Problematic:

  • AI Crawlers Struggle to Access Content: JavaScript-based websites often hide key content behind layers of code, making it challenging for AI crawlers to extract relevant information.
  • Error Risks: For example, an error (such as a 500 response) may prevent AI tools like ChatGPT from accessing your site.

How to Fix It:

  • Test Crawlability: Use the "View Page Source" function on your browser. If you can’t find visible, readable text in the source code, AI crawlers likely can’t either.
  • Clean Code Practices: When hiring a web developer, review their portfolio and ensure they prioritize clean, crawlable code.
  • Dynamic Rendering: Consider implementing server-side rendering (SSR) or pre-rendering for JavaScript-heavy sites.

2. Adopt the LLMS.txt Standard

What Is LLMS.txt?

LLMS.txt is a newly proposed standard designed to guide large language models on which pages of your site matter the most. While not yet universally adopted, many major companies, like Stripe and Cloudflare, are already implementing it.

Why Add LLMS.txt?

  • It positions your site ahead of the curve as AI search grows.
  • There’s no downside - if AI platforms adopt this standard more broadly, having it in place ensures you're ready.

Pro Tip:

If your website uses a WordPress plugin like Rank Math, enabling and managing LLMS.txt files is just a matter of toggling the right settings.

3. Use Schema Markup to Enhance Context

Schema markup serves as a bridge, helping search platforms - both traditional and AI-driven - understand your content’s context.

Microsoft and other AI leaders have confirmed schema markup improves information extraction and understanding. For instance:

  • FAQ Schema: Tells the AI that content is formatted as question-and-answer.
  • Recipe Schema: Identifies content as recipes for food-related queries.

How to Implement Schema:

  • For WordPress users, SEO tools like Rank Math simplify schema generation. Choose schema types relevant to your content and populate the necessary fields.

4. Optimize Site Speed

Website speed isn’t just important for user experience - it’s critical in the AI search era.

Why Speed Matters for AI Crawlers:

  • AI platforms have limited time and token resources. Slow sites may be skipped entirely to save processing power.
  • Faster sites improve visibility, as they’re easier for both humans and bots to access.

Quick Tips for Speed Optimization:

  • Minify CSS and JavaScript: Remove unnecessary characters to reduce file sizes.
  • Lazy Loading: Defer loading images and videos until they’re needed.
  • Caching: Use tools like WP Rocket for efficient site caching and speed improvements.
  • Monitor Core Web Vitals: Regularly check Google Search Console for any speed-related issues.

5. Refine Robots.txt and Meta Tags

The robots.txt file and meta tags act as gatekeepers for your content, controlling what crawlers can access and index.

Robots.txt:

  • Use it to block or allow specific AI crawlers. For example, you might block GPTBot if you don’t want OpenAI accessing your site for training purposes.
  • Syntax Example:
    User-agent: GPTBot  
    Disallow: /  
    

Meta Tags:

If you have duplicate pages, canonical tags ensure search engines and AI platforms focus on the correct version.

Practical Tip:

Check your site’s settings to ensure noindex tags are applied only to pages you want excluded.

6. Leverage Sitemaps

Even in AI-driven search, sitemaps remain a vital tool for structuring your site’s content.

How They Help:

  • XML Sitemaps: Facilitate crawling and indexing by providing a clear map of your site’s structure.
  • HTML Sitemaps: Aid AI crawlers in navigating your site when XML sitemaps aren’t sufficient.

Implementation:

WordPress plugins like Rank Math allow you to create XML and HTML sitemaps automatically.

Key Takeaways

  • JavaScript Issues: Avoid hiding key content behind JavaScript to ensure AI crawlers can access it.
  • LLMS.txt: Implement this emerging standard to guide large language models effectively.
  • Schema Markup: Use structured data to provide context for AI and traditional crawlers.
  • Speed Optimization: Improve site speed to prevent AI crawlers from timing out.
  • Robots.txt and Meta Tags: Fine-tune crawling rules to allow (or block) specific bots.
  • Sitemaps: Maintain clear XML and HTML sitemaps to simplify site navigation for crawlers.
  • Cloudflare Settings: Double-check AI Crawler permissions if you use Cloudflare.

Final Thoughts

The AI search era is an exciting but challenging frontier for website owners. By prioritizing technical SEO adjustments, you can position your site to benefit from this shift, ensuring your content remains visible and relevant.

As AI continues to shape the way users interact with online information, taking proactive steps today will set the stage for sustained success tomorrow. Are you ready to adapt to the future of search?
