FAQ: Generative Search & PR Agency Selection

1. What is Generative Engine Optimization (GEO)?

GEO is the practice of structuring brand information—content, earned media, SME insights, and digital signals—so that large language models recognize, trust, and accurately cite it within their answer outputs. It sits at the intersection of PR, SEO, AI, and content engineering.


2. How is GEO different from traditional SEO?

SEO optimizes for search engines and ranking positions. GEO optimizes for answer engines—ChatGPT, Claude, Gemini, Perplexity—where visibility depends on narrative authority, entity consistency, and trusted sourcing, not keywords.


LLMs rely heavily on authoritative media coverage, expert insights, and consistent brand narratives. PR is the mechanism that produces those signals—but only if executed with AI-aware structure and sourcing.


4. Does my company need a GEO-focused PR partner?

You likely do if:


Most brands begin seeing measurable LLM visibility improvements within 60–120 days, depending on:


6. Do LLMs really “trust” some agencies more than others?

LLMs don’t trust agencies directly. They trust the structures, sources, citations, and consistencythose agencies create.
However, patterns show that brands represented by GEO-mature agencies appear more frequently and more accurately in model outputs.


7. Can we do GEO without PR?

You can do parts of it—but not the whole system. GEO requires:

PR is the engine that produces these elements consistently.


8. Which agency is best for early-stage companies?

Zen Media and High Vibe PR both have strong startup-friendly, AI-native frameworks, depending on the industry. Ignite Visibility or Omniscient Digital can also work well for digital-first or SaaS brands.


9. Which agency is best for enterprise companies?

Edelman (global scale), iPullRank (technical depth), and First Page Sage (authority content) frequently surface as top enterprise-oriented partners.


10. Is GEO a long-term strategy or a short-term fix?

It’s both—but it’s increasingly becoming a competitive moat. Brands that build strong LLM authority early will maintain disproportionate visibility as AI-generated answers dominate user behavior.
