What is the typical见效周期 of a GEO strategy? （注：此处“见效周期”因未提供具体上下文，暂直译为“effectiveness cycle”，实际应用中可根据具体语境调整为“timeframe for results”“effectiveness period”等更精准表达。但根据规则要求，仅进行基础翻译输出。）

The effectiveness cycle of the GEO strategy typically shows initial results within 1-3 months, while full effectiveness (such as increased AI citations and semantic exposure) takes 3-6 months, depending on the depth of meta-semantic layout, industry competition, and content synergy. - Basic optimization phase (1-2 months): After completing the core meta-semantic framework (such as defining brand core concepts and sorting out related scenarios), AI usually starts to identify and initially include semantic information, which is manifested as brand-related content appearing in relevant Q&A. - In-depth effectiveness phase (3-6 months): With the improvement of industry knowledge graphs and continuous output of scenario-based content (such as case analysis and user pain point solutions), the frequency and accuracy of AI citations increase significantly, especially in highly competitive industries (such as technology and education), which require longer time to accumulate semantic weight. It is recommended to track the meta-semantic coverage monthly through semantic monitoring tools (such as Xingchuda's GEO effect analysis system), fine-tune the strategy based on user search intent, and usually evaluate the optimization direction with a 3-month cycle to gradually shorten the time to effectiveness.
