Which AI search engines does GEO target?

GEO does not target one specific engine. It targets generative AI across the board.

238lab works primarily with ChatGPT, Gemini, Perplexity, Grok, Claude, Copilot, and Naver (Korea's dominant search engine, ~58% market share). We adjust priorities based on the client's target market.

Characteristics by Engine

• ChatGPT (OpenAI): Combines training data with real-time Browse. Responds strongly to authoritative external mentions and wiki assets.
• Gemini (Google): Built on the Google search index. Strongly tied to Google AI Overviews in its answers.
• Perplexity: Based on real-time web search and cites source URLs in its answers. Sensitive to freshness and page authority.
• Claude (Anthropic): Integrates web search and favors official sites and structured content.
• Copilot (Microsoft): Based on Bing search. Effective when integrated with IndexNow and Bing Webmaster Tools.
• Naver: Delivers Korean-specific answers built on the Naver search ecosystem (blogs, cafes, Knowledge-iN, VIEW).

How 238lab Sets Engine Priorities

• Domestic B2C: Naver + ChatGPT + Gemini first
• Domestic B2B and professional services: ChatGPT + Gemini + Perplexity first
• Global and overseas expansion: ChatGPT + Gemini + Perplexity + Claude + Copilot across the board
• Healthcare and beauty: Naver + ChatGPT focus (domestic search dominates)

Engine algorithms change constantly. We tune the optimization design at the start of the consulting engagement and recalibrate every quarter.
