Two brands appear in the same ChatGPT answer. One is described as a solid, well-reviewed option that teams trust. The other is listed as an option, though the model adds that some users report slow support. Both were mentioned. Only one is getting the click.
Visibility tells you that you showed up. Sentiment tells you whether showing up helped.
Presence is not the same as endorsement
It is easy to treat a mention as a win. You searched, your brand was there, job done. But a mention is just the door. How the model talks about you decides whether the buyer walks through it. This is a different axis from whether you are mentioned or cited. You can be both and still lose, if the description plants doubt.
Where AI sentiment comes from
Models do not invent an opinion of you. They aggregate the language already out there: reviews, forum threads, press coverage, comparison pages, and your own copy. That tone gets distilled into how you are described. If your G2 reviews keep raising the same complaint, that complaint tends to leak into the answer. The mechanics are the same signals that drive which brands AI recommends in the first place.
In short, AI sentiment is a mirror of how the internet talks about you, filtered through the model.
The three states, and what each one does
Positive: reinforces the recommendation and often lifts you higher in the answer. The model is effectively vouching for you.
Neutral: you are on the list, but nothing tips the buyer toward you over the next name.
Negative or hedged: the mention now carries a warning. In some cases this is worse than being absent, because the buyer leaves with a concrete reason to skip you.
This is why mention count alone is a misleading metric. Ten neutral mentions can be worth less than three warm ones.
How to read and improve it
Treat sentiment as something you track, not a vibe you guess at.
Measure it per platform and per prompt. You can read as trusted in ChatGPT and lukewarm in Perplexity, simply because they lean on different sources.
Fix the sources, not the symptom. Address the recurring review complaint, refresh the outdated comparison page, earn balanced coverage that gives the model better language to draw on.
Re-check after changes. Sentiment moves as your sources move, so what you fixed in March can read differently by summer.
The goal is not just to be in the answer. It is to be the name the model describes in a way that makes the buyer stop looking. Trackbase tracks sentiment alongside visibility across every platform, so you can see not only where you appear, but how you sound when you do.
