Note that for prompts already mentioning your brand visiblity will always be high. * For each individul prompt HeyAmos gives you a trend graph showing Visibility for you and competitors over time — with the option to drill down for each prompts category and AI model. Image ## Ranking / Position **What it measures:** Where you rank when your brand is mentioned within a list of brands. In traditional search, ranking high matters for visibility. With AI answers, ranking matters less because users typically read the complete answer anyway. In this example below Singapore Airlines ranks nr 1 for the prompts "What are the best airlines for luxury travel": ## Sentiment **What it measures:** Whether AI models describe your brand positively, neutrally, or negatively when they mention you. Keep in mind that AI models tend to avoid negative comments about brands, so most mentions will likely be positive or neutral in sentiment. Image
