JavaScript

Classic search engines execute JavaScript within a browser-like environment to fully render and index dynamic web content, focusing on real-time web discovery and content accessibility. 

LLMs, on the other hand, process JavaScript as learned textual patterns from their vast training data, without executing it, primarily to enhance their language understanding and generation capabilities. 

This distinction has significant implications for how content dynamically loaded by JavaScript is perceived and utilized by these different AI systems.

Many LLM crawlers approach JavaScript not as executable code, but as a form of static text or code snippets found within their colossal training datasets. LLMs do not possess a rendering engine, nor do they actually execute the JavaScript. 

Instead, LLMs tokenize the patterns in the code, develop a probabilistic understanding of what "valid" or "typical" JavaScript looks like, and can infer the likely purpose of functions or structures based on the context of their training.

This means an LLM can recognize, generate, or reason about JavaScript code based on learned patterns, but they cannot run the code to see its dynamic output or interact with a live webpage. 

Using SSR, as is standard on Wix and Wix Studio, helps your content to be better rendered by LLMs and classic search engines.
