Ads in AI answers vs paid placements in cited sources
There are two ways to pay for visibility in AI search. Ads in AI answers are sponsored slots that ChatGPT and other assistants show next to or inside an answer; ads trackers list which advertisers bought them. Paid placements in cited sources happen one step earlier: a brand pays to be featured in a "best of" listicle, a review roundup or a comparison page, and AI answers then cite that page, so the brand appears in the organic answer. The second kind looks like an earned citation, which is why it is harder to spot.
Ads in AI answers
A sponsored slot in a ChatGPT answer. Ads trackers show which advertisers bought it.
Paid placements in cited sources
A brand pays to be listed in a "best CRM tools" article; ChatGPT cites that article and names the brand.
