PHYSIX OBSERVATION

AI assistants are becoming a new traffic gateway, and whether a site gets cited directly affects its exposure. IsCited lowers the barrier to GEO testing to $19, making it a low-cost trial tool for small and mid-sized site owners. But it asks only 5 questions per week, a sample size that is on the small side, so its effectiveness remains to be verified.
