Cost per lead for Littleton home services: clicks, calls and lifetime value

If you run a home services company in Littleton — plumbing, HVAC, electrical, garage doors — your cost per lead is not the click price in your Google Ads account. It is the arithmetic that runs from clicks to calls to booked jobs, and most owners have never worked it out for their own business. This article walks through it with your numbers, not ours.

Clicks to calls to jobs: the arithmetic in order

Three numbers decide what a customer costs you, and only one of them lives in your ad account.

Clicks to calls. Someone in Littleton searches "water heater replacement" or "furnace not turning on," clicks your ad or your listing, and either calls or doesn't. If your site loads slowly on a phone, doesn't show a tappable number at the top, or looks abandoned, a share of the clicks you paid for produce nothing. You paid for them anyway. Divide last month's ad spend by the number of calls it generated — not clicks, calls — and you have your real cost per lead. For most owners this is the first unpleasant surprise: the $8 click and the cost per call can be very different numbers, and the gap between them is entirely about what happens after the click.

Calls to booked jobs. Not every call books. Some are price shoppers, some are outside your service area, and some — this is the expensive one — ring while you're under a house with your hands full. In home services the caller is often standing in a cold house or next to a leaking tank, and they call the next company within minutes. A missed call in this trade is usually a lost job, not a delayed one. We wrote about this mechanism in detail in the jobs Highlands Ranch businesses lose while on another job, and it applies just as much south of the river. Divide your cost per call by your booking rate and you finally have the number that matters: cost per booked job.

A worked example — yours will differ. Suppose your clicks average $10, one call comes in per five clicks, and you book half the calls that come in. That's $50 per call and $100 per booked job. Whether $100 is expensive is the wrong question until you ask the next one.

Why the answer depends on lifetime value, not the click

A $100 cost per job means completely different things depending on what the job is worth over time — and in home services, the first ticket badly understates it.

The homeowner who calls you for a $250 drain clearing is the same homeowner who calls you three years later for a repipe, and who tells their neighbor which company showed up on time. The furnace tune-up customer becomes the furnace replacement customer, and in this trade a replacement can be ten or twenty times the ticket that brought them in. If you only compare acquisition cost to the first invoice, you will conclude that advertising is too expensive and cut it — right before the season when the phone should be ringing.

Season matters here too. In July and during the first October cold snap, demand spikes, your booking rate rises, and your cost per job drops on its own. In the shoulder months, clicks may cost the same but calls are scarcer — and yet a customer acquired in April fills a schedule that would otherwise sit empty. Judging your numbers off a single month, peak or slow, tells you almost nothing. We look at at least a full season before drawing conclusions, and ideally a full year.

One more piece: paid clicks are rarely the whole picture. One of our clients, a Denver cleaning company, booked $16,100 across 67 jobs in its first three months, and by month three 30% of that revenue came from free search — 21.7% averaged across all three months. That is one client's figures, not a promise, but it illustrates the point: your blended cost per customer includes the leads
