Subscribe to independent observations of AI visibility and recommendation rank, then give your GEO provider objective TDR metrics to improve.
Investigations, public methods and worked audits designed for brands, investors and journalists who need evidence they can trust.
A worked statistical examination of a GEO provider's published case-study claim, using demonstration data and a pre-specified null model.
Our public framework for measuring AI appearance rate and recommendation rank before and after a GEO engagement.
A redacted example showing the evidence, uncertainty and conclusions a brand receives from an independent effectiveness audit.
Initial documents serve as methodological proofs-of-concept. Production measurement programmes require verified client data.
For each subscribed brand, we define the target audience, markets, AI models and core metrics. We monitor continuously and version the prompt test set as our research identifies changes in audience behaviour, preserving comparability over time.
Specify the brand, target audience, markets, AI models, observation window and metrics before monitoring begins.
Track AI appearance rate and recommendation rank over time, versioning test prompts as audience behaviour evolves.
Check anomalies, uncertainty and trend reliability across repeated observations before reporting a change.
