Research archive. The current AI visibility service is separate from these dated AI-search observations.
AI visibility research and dated answer studies.
Explore recorded brand mentions and surfaced citations, with each study’s dates, scope and limits. The AI-answer records below were captured in July 2026. The September GitLab study separately examines technical access.
The citation index
A public, cumulative record of which named brands ChatGPT named or cited for their category's buyer questions. The intended cadence was weekly; sampling is currently paused, the last real sample is dated 2026-07-23, and missed runs remain visible rather than being backfilled. Failure included.
The citation gap on real brands
Point-in-time samples of selected brands against buyer-shaped category questions. Names are withheld and metrics banded; the answer-level observations, source composition, selection method, and limits are published.
GitLab: crawl rules and server responses.
Earlier reports
These two archived reports record selected technical site conditions across anonymous samples of independent Swiss businesses. They do not establish real-crawler access, retrieval, citations, or recommendations.
Archived 2026-07-11: reports 001 and 003 used an earlier technical site-check protocol and remain online with later evidence-boundary corrections. Report 002 (Milan) has been removed.
How 30 Swiss law firms and fiduciaries responded to technical site checks
30 independent Swiss law firms, notaries, and fiduciaries checked through an earlier site-file, homepage-markup, and ordinary-IP user-agent simulation protocol.
How 24 Swiss private clinics responded to technical site checks
24 Swiss private clinics checked through an earlier site-file, homepage-markup, and ordinary-IP user-agent simulation protocol.
About this series
The September 2026 GitLab study compares public robots rules with ordinary-IP crawler user-agent simulations across three root URLs. Earlier Swiss reports recorded selected site files, homepage markup, and user-agent simulations. The July 2026 citation series browser-sampled ChatGPT and recorded named brands and surfaced sources. Each study keeps its method, dates and evidence limits attached to its observations.
The AI Citation Index is paused after three entries. BDR-1.0, the unlaunched Renewal Evidence Review, and the 90-Day AI Search Decision Lead are historical or suspended designs. Deep Ocean has no current commercial offer. Research on this page is not client, product, demand, or investment validation.

The current direction focuses on brand mentions and citations in AI answers. These studies preserve their original dates and methods; they are research records, not customer results.
