Is GVS the same as search ranking?

No. GVS measures citation and surfacing visibility in AI answers and generative engines, separate from link ranking.

Does passing schema raise GVS?

No. Schema validity is one step; surfacing, citation, and answer absorption are measured separately.

A causal-isolation method: publish article pairs that differ only in a test variable to measure the differential effect.

No. Their indexes and rankings differ, so GVS (Google) and GVS-N (Naver) are isolated.

Measurement is based on per-engine surfacing/citation observation, and AUTHON discloses the methodology and its limits transparently.

GVS (Generative Visibility Score) is AUTHON's metric for citation and surfacing visibility in AI answers and generative search.

Axis separation: crawlable → indexed → surfaced → citation selected → answer absorption → re-measure. Each axis is measured independently (schema validity alone does not equal success).
Causal isolation (matched-pair): publish article pairs that differ only in the test variable to measure the differential, isolating confounds (engine updates, competitors, query drift).
Per-engine isolation: Google and Naver are measured on separate axes (GVS / GVS-N).

See the measurement-protocol document in this repository for the full protocol.
