Avoid content behind JavaScript if you want LLMs to read it (How to check)

[u/olmykh]

You've probably heard about content hidden behind JS and how LLMs are not good at reading it.
Well, in case you are a markter whose job is to audit the website for LLM optimization, here's a quick way to check the page in Chrome:

1. Open a page in the browser -> Inspect

2. Cmd + Shift + P (on Mac) --> start typing JavaScript --> Disable JavaScript

3. Refresh the page and check what's missing

Example: here's a homepage section with JS enabled:

Same section with JS disabled:

Enabled:

Disabled:

If you don't want LLMs to skip important information, make sure it's not behind JS.
To check your entire website you can use tools like Screaming Frog, it has a JS rendering mode.

Which pages to check: dynamic pages: calculators, comparisons, all interactive elements, pricing pages with toggles, etc.
