Understanding the Math
ROI for Google Ads is calculated as: (Revenue - Ad Spend) / Ad Spend x 100. For hvac in San Francisco, the average cost per click is $18.00, which means a $600 monthly budget generates roughly 33 clicks.
At a 7% landing page conversion rate (the benchmark for optimized local service pages), those 33 clicks produce approximately 2 leads. At $500 of expected revenue per lead for hvac (a figure that already allows for the leads that never close), that translates to $1,000 in monthly revenue.
The key variable is close rate. The per-lead value above reflects a typical one; a business that answers calls within 5 minutes and follows up on every lead closes a larger share of the same leads, which raises the value of each one and the return with it.
