PHYSIX OBSERVATION
Generative search is becoming a traffic gateway, and whether a site can be read and cited by AI directly affects its exposure. This free tool opens up the starting point of paid audits, lowering the barrier to self-checking, but a snapshot is not the result, and site owners still need to judge in light of content quality. The signal is that AI-oriented website optimization is moving from concept to something actionable.
