Yup. Amazon also has the advantage of dark UI patterns; they put sponsored listings inline with normal product results in the exact same style. I'm the (probably atypical) sort of person who will deliberately not click on a sponsored listing even if it seems the most relevant, and I still regularly click sponsored items on Amazon by accident. I back out if I notice this, but I'm sure I've bought a few products this way. These seem like very effective ads to me.
