Measurement & Analytics
Sentiment Analysis (AI Mentions)
Sentiment analysis of AI mentions measures whether ChatGPT, Perplexity, Claude or Gemini describe a brand positively, neutrally or negatively when it appears in their answers. Unlike social listening, it evaluates the framing an AI model itself generates, revealing how each engine characterizes your strengths, weaknesses and reputation to buyers.
Why sentiment matters more than mention counts
Counting how often an AI engine names your brand only tells half the story. A mention that frames you as expensive, dated or a distant runner-up can do more damage than no mention at all, because users treat AI answers as neutral expert advice. Measuring sentiment alongside mention rate separates visibility wins from reputation problems: two brands with identical AI visibility can be positioned completely differently inside the same answer.
Sentiment is typically scored on a scale from negative to positive for each individual mention, then aggregated per prompt, per topic and per AI provider. The aggregation matters because a single glowing answer can mask a pattern of lukewarm framing across the prompts your actual buyers ask.
How AI mention sentiment is measured
The standard approach extracts every brand mention from collected AI answers, captures the surrounding context, and classifies the framing as positive, neutral or negative, often on a continuous score from -1 to 1. Context is essential: the sentence "cheaper than X but less reliable" is positive on price and negative on quality, so good systems look at the full passage rather than keywords.
Because of answer volatility, sentiment must be sampled repeatedly over time rather than spot-checked once. A brand can read as positive in one run and neutral the next, so trends across daily samples are more trustworthy than any single answer. Tracking by provider also matters, since models trained on different data often frame the same brand differently.
Acting on sentiment data
Negative or lukewarm framing usually traces back to sources the model leans on: outdated reviews, old pricing pages, or competitor comparison content. Fixing sentiment means finding and influencing those sources, refreshing your own pages, and earning third-party coverage that reframes the narrative, a core part of any GEO strategy. Platforms like Geonimo score the sentiment of every brand mention per provider through built-in sentiment analysis, so teams can see exactly which engines and prompts drive negative framing and prioritize fixes accordingly.
Frequently asked questions
How is AI mention sentiment different from social media sentiment?
Social sentiment measures what people say about you; AI mention sentiment measures what the models themselves say when answering buyer questions. AI framing is synthesized from training data and retrieved sources, so it changes with model updates and source content rather than with daily conversation volume, and it directly shapes purchase decisions.
Can I improve how AI models talk about my brand?
Yes, indirectly. Models echo the sources they were trained on and retrieve at answer time. Updating your own pages, correcting outdated third-party content, earning fresh reviews and publishing clear comparison content all shift the inputs. Changes typically show up gradually as retrieval indexes refresh and models are updated.
Why does my brand sentiment differ between ChatGPT and Perplexity?
Each engine uses different training data, retrieval sources and ranking logic. Perplexity leans heavily on live web retrieval, so recent articles dominate its framing, while other models may rely more on older training data. Measuring sentiment per provider tells you which engine needs attention and which sources drive its framing.

AI Brand Perception
AI brand perception is the composite picture AI models hold and present of a brand: what it does, who it serves, its strengths, weaknesses and standing versus alternatives. Formed from training data and retrieved sources, this perception shapes millions of AI-mediated recommendations and can lag or contradict a brand's current reality.
Brand Mention (in AI Answers)
A brand mention in AI answers is any instance where an AI engine names a brand in its generated response, whether as a recommendation, comparison entry, or passing reference. Mentions are the core unit of AI visibility measurement: tracking how often, where, and in what sentiment a brand is mentioned reveals its standing in AI search.
Mention Rate
Mention rate is the percentage of AI-generated answers that name a specific brand, measured across a tracked set of prompts. If a brand is mentioned in 30 of 100 answers collected for its tracked prompts, its mention rate is 30 percent. It is the foundational metric for quantifying brand presence in AI search.
Answer Volatility
Answer volatility is the tendency of AI engines to give different answers to the same prompt across runs, days and models, caused by sampling temperature, model updates and changing retrieval results. It makes single spot-checks unreliable for measuring AI visibility and is the core reason repeated daily sampling is required.
