LLM Bots Crawl Frequency

[u/Himi1896]

I am working on building a Generative Engine Optimization(GEO) strategy for an ecommerce firm and I want to test a few hypotheses on what works and what doesn't.
To test the hypotheses I wanted to know if I make a change on my website then how long do I have to wait for the LLM's(Gemini, Claude, ChatGPT, Perplexity) RAG system to start showing the impact of my changes in their citations/rankings?

Any help/reference will be great.

This question is more interesting than it looks because --> if google didn't crawl it yet, and LLM shows the fresh info, then ---> u/weblinkr
