Compare advertising areas after travel costs, not just lead costs

Choose operational zones that staff can recognize

A radius on a map is convenient for advertising, but it does not describe bridge crossings, travel time, parking, or the cost of returning for parts. Define a few service zones using places the team can deliver reliably. Write the dispatch rule for each zone before reviewing the campaign. The goal is not to produce a more decorative map; it is to compare work the business can fulfill under meaningfully different travel conditions.

Separate ad location from job location

Google's geographic reports distinguish targeted and matched locations, and a match can reflect physical location or interest. Use that view to inspect campaign distribution, not as a substitute for the address where the job happened. Collect an operational zone with the quote and confirm it after booking. Report unmatched or unknown zones honestly. Do not assign a customer to a postal area merely because an ad report contains that label.

Create a zone economics worksheet

For each zone, record ad spend, qualified inquiries, booked jobs, completed jobs, and the estimated variable contribution before advertising. Include actual travel costs where available and distinguish estimated figures from settled costs. Use the same review period and accounting method across zones. If shared campaign spend cannot be allocated reliably to job zones, show the available campaign-location view separately and note that a precise zone acquisition cost is not established.

Make expansion a capacity decision

An outer zone might produce valuable work but require longer appointment windows and fewer jobs per day. Check technician time, return visits, cancellation risk, and the minimum worthwhile job. Consider a limited test with clear service expectations instead of immediately increasing the whole radius. Avoid promising local presence where none exists. The business can serve an area without inventing a shop or implying a faster arrival than its route makes possible.

Avoid excluding a zone from one expensive lead

Small samples, one large job, or a delayed booking can dominate the result. Review why inquiries did not become completed work: wrong service, inaccessible appointment time, travel charge objections, or no response. These point to different actions. A lower lead cost does not resolve poor fulfillment, while a higher lead cost may still support profitable work. Treat suggested review intervals and spend caps as your management choices, not universal Google thresholds.

Measure the next area test consistently

Keep the zone definition, quote policy, and lead qualification stable during the test. Reconcile settled work after enough time for bookings to complete. Compare contribution after both travel and ads, and record changes in appointment utilization. If the outer zone consumes time needed for better core-area work, that opportunity cost belongs in the decision. The useful output is a documented continue, revise, or stop decision for that particular delivery area.

Worked example: illustrative figures

For example, Zone A spends $300 on ads and completes 6 jobs, each contributing $100 before advertising and after travel. Its contribution after ads is 6 × $100 − $300 = $300. Zone B also spends $300 and completes 6 jobs, but longer travel reduces contribution to $60 each: 6 × $60 − $300 = $60. Both have a $50 ad cost per completed job, yet their remaining contributions differ. These figures exclude fixed overhead and assume spend can be allocated reliably; they do not establish net business profit.
