Penumbra · Generative Engine Optimization

AI is talking about your brand right now. Do you know what it's saying?

ChatGPT, Gemini, Perplexity, and Grok already shape how customers discover your brand. Penumbra monitors, measures, and improves your visibility across every AI model — so you control the narrative before your competitors do.

AI models are the new front page

357% YoY growth in AI-referred traffic. Customers increasingly ask ChatGPT or Perplexity before they search Google.

You can't optimize what you can't see

No analytics, no alerts, no way to know if AI recommends you or your competitor — or recommends neither.

Competitors are already mentioned

AI models cite whoever has the best content and citations — not necessarily the best product. Silence is the worst outcome.

Traditional SEO doesn't transfer

AI engines synthesize answers from multiple sources. Page 1 rankings don't guarantee AI visibility. This is a new discipline.
