What this does not establish
Self-reported calling propensity and CTR are inquiries, not booked jobs, realized sales, incremental profit, Google Business Profile ranking, or evidence that adding a phone number alone causes the reported behavior.
Counterevidence & uncertainty
Calls appear commercially proximate—almost three quarters of ad-originated calls lasted over 30 seconds—yet the study supplies no conversion or incremental-revenue estimate.
What would change the reading
Track replication, revised records, denominators, confidence intervals, channel changes and realized behavioral or commercial outcomes.
