Summary

The open web's traditional search ranking dynamics are being inverted by AI, with top-ranked sites losing visibility while challengers gain, presenting an 18-month window for strategic adaptation. Research from Princeton highlights how over-optimization can harm AI visibility, and a "18 token magic number" is key for success in generative engine optimization. The takeaway is that established brands must under-optimize and leverage existing authority, while challengers can be aggressively strategic to gain visibility in this evolving AI landscape.
