An online pharmacy in Chile went from 0% to 66% visibility for the question "Where can I buy ISDIN, CeraVe, Eucerin or La Roche-Posay at the best price in Chile?", with a single article built to answer it the way people actually ask it.
The line sits at zero for almost two months and takes off on September 5, days after the article went live. Between September 5 and 30 it never dropped below 50% on any day.
Many people already ask ChatGPT where to buy something instead of searching on Google. And the AI's answer is, in practice, a short list of recommended stores, so a store that is not on that list rarely makes it into the decision.
This pharmacy sells exactly the brands in that question, but for almost two months of measurement it practically never appeared in the answer. The assistants had no page of theirs that answered exactly what people were asking.
We tracked the question every day in ChatGPT and Gemini and saw that the pharmacy almost never appeared, even though it sold exactly what was being asked about.
We published an article on its blog about where to buy those dermocosmetic brands at the best price in Chile, with the information an assistant needs to recommend a store.
We measured every day and by engine, not as a monthly average, to see the exact moment of the change and which source the AI used to answer.
In retail, the purchase questions people ask AI tend to be few and very specific. Having a page that answers each one is one of the most direct ways to get into that short list. The measurement covers two engines and one question, and Gemini relied more on other pages than ChatGPT did, so the result speaks to that specific question.
In 30 minutes we check which purchase questions you appear in today on ChatGPT and Gemini, and which ones need a page that answers them.
