Authority Sources

Discover the websites ChatGPT, Gemini, Claude, Perplexity, and more cite as sources

When ChatGPT, Gemini or Claude answer a question about your industry, they don't make it up — they cite specific websites. Lumen shows you exactly which sites those are, where you appear, and where citation gaps exist.

Authority Sources

What you get

Know which sites influence AI responses

It's not magic. ChatGPT, Gemini, Claude, Perplexity, and more read specific domains to answer. Lumen shows the authority ranking: which sites are cited most, which are gaps.

Prioritize your SEO and PR efforts

If an important authority source doesn't cite you, you know where to focus. Pitch them content, improve your presence there, or build relationships.

Detect citation coverage gaps

You appear on some sources but not others the AI reads. That's a clear PR or SEO opportunity Lumen identifies.

  3. We show the authority ranking

    In your dashboard, see a ranking: domains already citing you (celebrate), and domains the AI uses but you're missing (opportunities).
