You should divide your local advertising budget between Yelp and LSA based on which platform produces more qualified customers and revenue, rather than splitting the budget 50/50. Start by giving more of your budget to the platform that consistently delivers better customer acquisition costs and conversion rates, while keeping enough spend on the other platform to test whether it brings incremental customers.
For example, if LSA generates more high-intent leads and booked jobs, you might put 60–70% of your budget into LSA and 30–40% into Yelp. But if Yelp brings in customers that LSA does not reach, keeping a meaningful Yelp budget can still make sense.
Review the results regularly and compare qualified leads, booked jobs, new customers, customer acquisition cost, and revenue from each platform. The right split is the one that maximizes profitable new customers, not simply the platform that generates the most leads.
