Hey everyone, I’m Chris with Nectiv, and for today’s GEO tip, we’re going to talk about **AI crawlers and their inability to access JavaScript content**.

This was a great study done by **Versil** a while back where they analyzed different AI crawlers. What they found was that **crawlers like ChatGPT and Claude cannot access JavaScript**. They may fetch the JavaScript files, but they **cannot actually execute them**.

That means if your content relies heavily on JavaScript, **AI crawlers aren’t going to be able to see it**, and you’re going to **limit your visibility** in both AI search and traditional SEO.

### Quick Example: Uniqlo

On the **Uniqlo site**, they load all of their content on their international subdomains using JavaScript — it’s **client-side rendered**.

-   On their **French site**, if you **turn JavaScript off**, none of the content loads.
    
-   I tested this in ChatGPT by asking:
    
    > “Can you read this page? Don’t read any others — just this one.”  
    > It used the **search function** to try to access it — but it **couldn’t fetch the content**.
    

Then I switched to a **US version** of the site (which **does not rely on JavaScript**) — and **ChatGPT could access it** just fine.

### Why This Matters

If you’re building your site like Uniqlo — **relying heavily on JavaScript for content delivery** — you’re likely **limiting your visibility within LLMs**, AI search platforms, and even traditional SEO.

### Best Practice

To maximize visibility:

> **Serve your content in the original HTML** whenever possible.

That’s going to ensure your content is accessible to **AI crawlers like ChatGPT**, **Claude**, and others — and position your brand better for inclusion across both AI-driven and traditional search experiences.
