Core Viewpoint - The article discusses the ongoing issue of GEO "AI poisoning" business despite the exposure during the 3·15 event, highlighting the manipulation of AI responses through the creation of false information [1][2]. Group 1: Current Status of GEO Business - Following the 3·15 exposure, platforms like Xianyu have blocked direct keywords related to "GEO optimization," but related services can still be found using more obscure terms like "engine optimization" [2]. - GEO optimization services are offered in two models: software service priced at 398 yuan/month or 1980 yuan/year, and agency operation priced at 3980 yuan/quarter or 9800 yuan/year [4]. Group 2: Mechanism of GEO Optimization - GEO (AI search recommendation/optimization) aims to ensure that brand and product information appears prominently in AI-generated answers, operating on the principle that "answers are advertisements" [5]. - The process involves "AI distillation," where keywords are inputted to generate related questions, followed by automated content creation and distribution across various self-media platforms [5][6]. Group 3: Risks and Implications - The GEO black market represents a shift from traditional search engine optimization to more dangerous "cognitive manipulation," undermining user trust in AI commercialization [7][8]. - The exploitation of vulnerabilities in the RAG (retrieval-augmented generation) technology used by mainstream AI models allows for the systematic pollution of AI's training data with false information [9]. Group 4: Recommendations for Mitigation - To combat the issue, a comprehensive defense system involving technology, ecology, and legal frameworks is necessary, including the establishment of a high-confidence "whitelist" for credible sources [10]. - Content platforms must take responsibility as "data gatekeepers" for AI, and legal definitions of malicious data poisoning should be established to deter such practices [11].
