What is generative engine optimization for press releases, and how does it differ from a traditional newswire?

Generative engine optimization (GEO) for press releases is the practice of structuring a release so AI engines like ChatGPT, Claude, Perplexity, and Gemini will cite it as an answer source. It differs from a traditional newswire in three ways: surface shape (GEO publishes canonical /r/$slug pages with QAPage JSON-LD; wires publish to syndication networks AI crawlers do not prioritize), discoverability (GEO enrolls each release in an llms.txt feed and pings IndexNow; wires rely on journalist pickup), and measurement (GEO tracks live AI engine citations per release; wires count human impressions). PressGEO is built for GEO.
