Most contractors are told marketing ROI is complicated and hand a dashboard with fifty metrics. It isn't, and you don't need the dashboard. ROI is one idea (did this make more money than it cost) measured with a few honest numbers. Here's the plain-English version.
ROI is revenue versus spend, by channel
That's the whole concept. For each marketing channel, you want to know: how much did I spend, and how much revenue did it produce. Everything else is supporting detail. If a channel costs 2,000 dollars a month and produces 12,000 in booked revenue, that's a clear win. If another costs 2,000 and produces 1,500, cut it. The hard part isn't the math, it's getting honest numbers, which means attribution, covered in closed-loop attribution for home services.
The numbers that matter
Track these per channel and you're ahead of almost every competitor:
- Spend. What you put in.
- Booked jobs. Not leads, jobs that became work.
- Revenue. What those jobs were worth.
- Cost per booked job. Spend divided by booked jobs. The single best efficiency metric, explained in cost per booked job vs cost per lead.
- Close rate by source. Reveals lead quality, a channel with cheap leads but a terrible close rate is expensive.
Five numbers. That's the scorecard.
The vanity metrics to ignore
These feel like progress and tell you little on their own:
- Impressions. Being seen isn't being hired.
- Clicks. A click that never calls is worthless.
- Raw lead count. 100 junk leads lose to 20 real ones.
- Rankings alone. Ranking number one with unanswered calls produces nothing, the trap in why you rank but get no calls.
Use these as diagnostics if a real number drops, not as the scoreboard.
What to review each month
Once a month, sit down with the scorecard:
- Cost per booked job by channel, is it trending down or up?
- Revenue by channel, where is the money actually coming from?
- Close rate by source, any channel sending junk?
- One decision: what gets more budget, what gets cut?
That's a 20-minute review that most contractors never do, and it's worth more than any dashboard.
Why this beats trusting your gut (or your agency)
Without these numbers, you fund what feels busy and trust whoever claims credit. With them, you fund what produces revenue and hold every channel and every vendor accountable. It's also how you stop the most common waste: pouring money into a channel that looks active and books almost nothing.
The bottom line
Contractor marketing ROI is simple: spend versus revenue, by channel, judged on cost per booked job. Track five numbers, ignore the vanity metrics, review monthly, and reallocate. No dashboard required, just honest attribution and a few minutes a month.
