JavaScript SEO & AI Search

This bonus module answers questions like:

• Which LLM bots render JavaScript and which don't?

• What is the potential impact of having a JavaScript-reliant website in 2025?

• How to audit JavaScript from an AI search optimization perspective

Please note: “LLMs” themselves are not crawling anything, AI bots from LLM companies are. It’s like the difference between Google, Googlebot, and caffeine (the indexing engine).

Tory & Sam use “LLMs” in this training session to mean “AI companies using LLM technology”.
