For AEO, sentiment is what separates a useful citation from a damaging one. A model that mentions your brand in the context of "great pricing" is doing different work than one that mentions you with "common complaints". Tools like Bluefish surface this through favorability scoring. HubSpot AEO tracks sentiment for one brand daily across ChatGPT, Gemini, and Perplexity.
