Every booked job, traced back to the exact ad.
Modern Plumbing Group is a plumbing business running both emergency and planned work. We run their Google Ads and the attribution underneath it.
Modern Plumbing Group: phone calls and ServiceM8 jobs joined to the ad account.
The attribution spine was built first. Phone-call tracking and ServiceM8 job records are joined back to the ad account, so campaigns are matched to real calls, real jobs and real job value. In one 30-day validation window, 65 tracked calls and 160 jobs flowed through that pipeline and reconciled.
Google Ads is then run against booked jobs and job value rather than click-through rate, with suburb-level intent capture and emergency work kept separate from planned work.
All of it reports into a private client dashboard showing spend, calls, jobs and cost per booked job in one view, updated continuously rather than at the end of a reporting month.
Other trade businesses now ask for this engagement pattern by name.
