Field notes
The homepage separates question type, model, repetition, and recommendation outcome instead of treating AI visibility as a single score. Its Route 186 pilot reports 430 observations, including 415 valid responses, and compares unnamed prompts with prompts that include the venue. The page says the displayed numbers are a baseline and that post-improvement remeasurement is planned, so the current material documents an observation method rather than a proven optimization result.
