Understanding the Math
ROI for Google Ads is calculated as: (Revenue - Ad Spend) / Ad Spend x 100. For plumbing in Washington, 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. At $350 of expected revenue per lead for plumbing (a figure that already allows for the leads that never close), that translates to $1,400 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.
