PHYSIX OBSERVATION

Generative search is reshaping SEO logic, shifting focus from keyword rankings to content adaptation for 'AI citation.' CiteGraph reveals distinct 'tastes' across models, such as Gemini's preference for lists and Claude's affinity for step-by-step guides. This warns practitioners that a one-size-fits-all content strategy is obsolete; optimization must be tailored to specific engine structures. However, the tool emphasizes that matching does not equal commitment, cautioning the market against over-interpreting algorithmic black boxes. While technical barriers have lowered, trust barriers remain significant.
