Method
A barometer of 251 Portuguese B2B companies across 18 sectors. For each, we cross-referenced organic Google strength (0 to 100, from median web-search position) with visibility in the answers of one AI assistant (Claude, in memory and with search). Mentions detected by literal match on name and domain. Exploratory and directional, one engine.
Findings
- Average Google strength 30 of 100; average AI visibility 18 of 100.
- 41% of companies are not mentioned by the assistant at all.
- 59% appear in 10% or fewer of the buyer questions.
- The gap is largest where Google strength is high and AI visibility low: lawyers, clinic software, property management.
