Where ten links used to be,
there is now one answer.
Gartner predicts brands' organic search traffic will fall by 50% or more by 2028 as consumers move to generative AI search. A brand missing from the answer never even gets compared — and until you measure it, that answer is invisible.

Korean-first
GEO born in the Korean market
Global GEO tools see the world through English prompts. Korean customers ask AI differently — and that difference is the score difference.
We ask in Korean
Not translated English prompts — real questions Korean consumers ask, with search conditions matching real Korean users.
Naver AI, one metric
Global engines only show half the Korean market. Naver AI tracking is on our expansion roadmap.
Global expansion for K-brands
Starting from the KR-Seoul region, with US · EU · JP data residency on the roadmap — one yardstick for home and abroad.
Honest with numbers
Every score carries a 95% confidence interval; every data point carries a source badge. We don't fake certainty.
No Black Box
We publish exactly how the score is made
It's reasonable to distrust AI-visibility metrics. So GEO Surfer hides nothing — which rules, how many runs, and how certain, all shown together.
12 rules × 3 layers
Content is scored by 12 GEO rules across structure, trust, and citation layers. Every rule and weight is published inside the product.
4 scoring presets
Balanced · E-commerce · B2B SaaS · News. Pick — and inspect — what your industry should weigh more heavily.
Repetition + confidence intervals
Judged by the distribution of repeated runs, never a single response — every score ships with a bootstrap 95% CI.
