What GEO is (and is not)

GEO means generative engine optimization: whether ChatGPT, Gemini, Claude, Perplexity, or Grok mention your brand when someone asks a question your customers actually ask.

It is not a secret Google ranking factor. It is not a score we invent. Halcyn stores the raw answer and whether your domain or brand name appeared.

What you do on the site

Connect the domain. Add prompts (or let us suggest them). We query the engines we have keys for. Grok is included. Other engines run when those API keys are on the server.
