How does Lumen measure my AI visibility?

“You define prompts that represent how your customers search for solutions (for example, “what’s the best CRM in Argentina?”). Lumen runs them on ChatGPT, Gemini, Google AI Overviews, Claude, Perplexity and Copilot at your plan's frequency and analyzes each answer: whether your brand appears, in which position, with what context, and which competitors are mentioned.”
