LSA generally gives you better visibility into the source and quality of a service lead because it is built around direct lead generation, while Yelp provides more visibility into customer activity within its marketplace. With LSA, you can see lead details and track actions such as calls, messages, or bookings, then connect those leads to your CRM to determine whether they were qualified and became customers.
Yelp can still provide useful data, such as customer interactions and leads generated through your Yelp presence, but you may need your own CRM and tracking setup to understand the lead’s full quality and revenue impact.
For a fair comparison,track both platforms using the same metrics: lead source ---qualified lead --- booked job --- new customer --- revenue. That gives you a much clearer picture of which platform is actually producing valuable customers, rather than simply reporting more leads.
