Yes. Yelp can charge for advertising exposure or engagement even when that exposure does not result in a direct lead, depending on the type of Yelp advertising campaign you’re running. Yelp’s advertising products can use metrics such as impressions, clicks, cost per click, and other actions, so not every paid interaction necessarily becomes a phone call or customer.
That’s different from LSA, where the core model is focused on paying for leads rather than simply getting your business in front of someone.
So when comparing Yelp with LSA, don’t look only at the number of leads reported. Track impressions or clicks.. qualified leads...booked jobs...new customers ... revenue. That will show whether you’re paying for useful demand or simply buying exposure.
