The most effective way to track brand sentiment in LLM mentions is to use specialized AI monitoring tools that run targeted prompts through multiple LLMs like ChatGPT, Perplexity, and Google's AI Mode to capture how AI systems describe your brand, then analyze the sentiment and context of those responses.
Start by collecting baseline data from diverse LLM platforms, then establish regular monitoring cycles to track changes over time. Monitor both direct brand mentions and indirect references where your products or services might be recommended.
