PHYSIX OBSERVATION

AI answers are becoming a new traffic gateway, and Yaystack has turned GEO/AEO from a concept into a quantifiable product—the direction is right. But the score depends on a single AI analysis, and a variance of ±10 means the results are for reference only; enterprises should not over-rely on a single score for decisions, and it remains to be seen whether its methodology can gain industry recognition.
