Does ChatGPT recommend your brand?

We ask four answer engines the questions your buyers actually ask — “what are the best X brands?” — and show you who gets named. Usually it is not you.

the five questions

01What are the best magnesium supplements brands right now? Name specific brands.
02I want to buy magnesium supplements. Which brands are actually worth the money, and why?
03Which magnesium supplements brands are third-party tested and trustworthy?
04Recommend magnesium supplements for someone buying for the first time. List a few specific brands or products.
05What do you know about your brand (yourbrand.com)? Is it a reputable magnesium supplements brand?branded

Four are unbranded buying questions — the ones that decide whether you get recommended at all. The fifth asks the engine directly what it knows about you.

why this matters

Answers, not ten blue links
An assistant names three or four brands and the shopper picks one. There is no page two to be on.
You cannot see it in Analytics
A recommendation inside ChatGPT leaves no referrer. The only way to know is to ask the engines directly, repeatedly.
It is winnable right now
Almost nobody in supplements and skincare is writing the dense, factual pages answer engines quote. That window closes.

How the check works

Each engine is asked the same five questions through the Vercel AI Gateway, with a leading model standing in for each assistant. We then read the brands out of every answer and check whether yours is one of them, or whether your domain was cited.

It is a snapshot, not a rank. Answers vary between runs and the consumer apps have their own retrieval, so treat this as a directional read — which is exactly why the paid product runs 50 to 300 prompts every week instead.
