Key takeaways
- Cost per lead counts form fills and calls. Cost per booked job counts jobs on your calendar, and only your CRM knows that number.
- Check the conversions Google reports against your own records before you trust any cost per lead.
- Split the number by service. A driveway lead and a house-plus-roof lead are not the same purchase.
- Clicks get pricier in spring because every rig in town turns its ads on at once. Starting earlier and rebooking last year's customers lowers the cost per job.
Google Ads cost per lead for a pressure washing company is the ad spend divided by the calls and forms it produced. That number is easy to see and easy to misread. The number that matters is cost per booked job, checked against your own calendar, and split by service, because a driveway lead and a whole-house lead are different purchases.
Cost per lead vs cost per booked job
Cost per lead tells you what Google charged to make the phone ring. Cost per booked job tells you what it cost to put a wash on the schedule. The gap between them is where most pressure washing ad budgets leak.
The gap is wider in this trade than most. Many callers want a price for "the house" without an address. Some want a single stoop cleaned below your minimum. Others are collecting three quotes for an HOA deadline and will take the cheapest. All of them count as leads in Google Ads. Few of them become jobs.
There is a second gap: what Google reports versus what happened. Google Ads counts conversions you told it to count (Google's conversion tracking). A form submitted twice, a 15-second call from someone looking for a rental shop, and a real house wash booking can all look the same in the dashboard. That is the verification gap. Close it with your own records, not the platform's.
From cost per lead to cost per booked job
- Leads you pay for Where it leaks: Spam and wrong numbers
- Real inquiries Where it leaks: Calls nobody answers
- Conversations Where it leaks: Quoted, never followed up
- Booked job Your real number: cost per booked job
Calculating your number
- Pick one full month in season. April or May shows the trade at full speed. A January month shows almost nothing.
- Count real leads. Pull every call and form Google Ads recorded. Remove duplicates, spam, and calls under about 30 seconds that never reached a quote. Call tracking helps here, because it records which calls came from ads (Google's call reporting).
- Match leads to jobs in your CRM. Look up each real lead in Jobber, ResponsiBid or your field service CRM. Count the ones that turned into a scheduled job, including jobs booked a few weeks after the first call.
- Divide. Spend for the month divided by booked jobs is your cost per booked job.
- Split by service. Run the same sum for house washing, roof soft washing, concrete and commercial. One blended number hides which campaign is paying for the others.
- Compare with what the job earns. Set the cost per booked job beside the average ticket for that service, and beside what a customer who rebooks next year is worth.
Worked example (hypothetical round numbers, not a benchmark). Say you spend $3,000 in April. Google Ads reports 60 conversions, a $50 cost per lead. Your check finds 12 duplicates and short calls, so you had 48 real leads. Your CRM shows 20 of them booked.
- Real cost per lead: $3,000 ÷ 48 = $62.50
- Cost per booked job: $3,000 ÷ 20 = $150
- Split by service: 8 driveway-only jobs averaging $200, and 12 house washes averaging $500, several with a roof or driveway added.
At $150 a job, the driveway jobs barely pay for the trip. The house washes carry the month. If 8 of those 12 homeowners rebook next spring without another ad click, their real acquisition cost falls by half. The next move is clear: shift budget toward house washing and roof terms, and stop paying full price for driveway-only clicks.
Why costs rise around spring, summer and the fall pre-holiday push
Click prices follow the season. When pollen turns siding green and HOA letters go out, most pressure washing companies in your area turn their ads on in the same few weeks, including the part-time operators with a trailer rig. More bidders on the same searches push each click up.
| Time of year | What happens to demand | What it does to your cost |
|---|---|---|
| Late winter | Few searches, few competitors | Cheap clicks, low volume. A good time to book early-season jobs. |
| Spring | Pollen, mildew and HOA notices drive searches | Highest competition. Cost per lead usually climbs. |
| Summer | Steady house washes, decks and concrete | Holds high while the schedule stays full. |
| Fall | Owners clean up before hosting the holidays | A second, shorter rise. Commercial clients prep storefronts too. |
Lowering cost per booked job
Lower cost per booked job by raising what each lead is worth and by wasting fewer clicks. Bidding less is rarely the answer.
- Raise the ticket. Offer the roof or driveway on every house wash quote. A lead that books two services costs the same to win as one that books a single driveway.
- Quote faster. A homeowner with an HOA deadline books the first credible quote. Quote from the address and satellite view the same day.
- Cut the equipment searches. Exclude rental, repair and "buy" searches. The Google Ads keywords guide lists the negatives to start with.
- Fill the route. Bid harder in the ZIP codes where you already have jobs scheduled, so the new job adds a stop, not a drive.
- Start before the rush. Run ads and email last year's customers in late winter, when clicks are cheaper, so part of spring is booked before competitors switch on.
- Rebook the customers you already paid for. A customer who rebooks every spring costs nothing in ads the second time. The repeat customers guide covers how.
