Understanding the Math
ROI for Google Ads is calculated as: (Revenue - Ad Spend) / Ad Spend x 100. For plumbing in San Francisco, the average cost per click is $10.49, which means a $600 monthly budget generates roughly 57 clicks.
At a 7% landing page conversion rate (the benchmark for optimized local service pages), those 57 clicks produce approximately 4 leads. With a 30% close rate and an average plumbing job value of $350, that translates to $420 in monthly revenue.
The key variable is close rate. A business that answers calls within 5 minutes and follows up on every lead can push close rates to 40-50%, which would increase the ROI from -30% to 5% or higher.
