ChatGPT is citing Reddit 88% less and Wikipedia 80% less than it was six months ago.
When it needs to check a fact, it’s increasingly going to your website instead.

Ahrefs has just analysed 15 million “fan-out” queries from ChatGPT, the behind-the-scenes searches it runs to research and check an answer. When the model searched specific sites to verify something, around three-quarters of the most-searched were brand sites.
Your website is increasingly becoming the place your facts get checked, as well as the place people convert.
There’s an uncomfortable bit too.
84% of factual prompts cited an official source, against 68% of comparison prompts.
You get cited when a buyer asks whether something is true, and much less when they ask which option is better.
In my opinion, the answer is the material considered-purchase brands are often reluctant to publish. Hiding it behind a form or a sales call costs you twice, once with the buyer and again with the model.
A few practical things I’d look at:
-
Find out which questions your buyers actually ask AI about your category, and whether you’re cited when they do. If not, see who is.
-
Publish the facts openly. Specifications, pricing or price ranges, eligibility, availability and how you work. If a buyer would ask it, answer it on your site.
-
Make those facts easy to check. Clear pages, named people, dates, methodology and structured data so the model can trust what it finds.
-
Take comparison questions seriously. Explain who you’re right for, who you’re not, and how you differ. Honest comparison content is where most brands are missing.
-
Look again at what you gate. If something builds confidence, the cost of hiding it is probably higher than the lead it captures.
-
Measure citations, not just traffic. Track visibility at prompt level and connect it to pipeline, so it’s treated as a commercial issue rather than an SEO one.
We saw this with a client recently, where structured data helped grow their monthly AI audience by 53%.
Your website actually matters more now than ever before.
