Method

The public method is on the methodology page.

Wombid is the measurement standard for whether ChatGPT, Gemini, Google AI Overviews, Claude and Perplexity name an Australian trade business.

Every Wombid run asks the same six buyer questions, filled with the trade and suburb, on those five engines plus the Google Maps local pack from Australian mobile search.

The Wombid Score uses epoch wombid-score-v4: 100 × (0.55 × mention rate + 0.20 × position quality + 0.25 × share of voice), then rounded to a whole number.

A missing Google AI Overview is n/a under the Absent-Overview Exclusion. It is never counted as a miss.

The score is a snapshot of one run. It does not predict calls, bookings or revenue. No one can guarantee an AI engine will recommend a business.
