Retargeting vs. Buying Shared Leads: The Real Cost

Two ways to buy the same job

Every home-service owner is really buying one thing: booked jobs. The debate over lead channels is just an argument about the cheapest honest way to get there. So let’s do the math instead of the marketing.

There are two roads. One is to buy leads from a reseller — Thumbtack, Angi, HomeAdvisor — where you pay per name and hope you’re the shop that closes it. The other is to re-warm the homeowners who already came to your own site, using retargeting, and pay only when one becomes a real, consented lead. They sound similar on a spreadsheet. On a cost-per-booked-job basis, they are not close.

What a shared lead really costs

Start with the sticker price. A shared lead on the big platforms runs roughly $46 to $53 depending on trade and market — ServiceMag’s Thumbtack review and HouseCall Pro’s Angi breakdown both land in that range, and SearchLight Digital pegs blended Google Local Service Ads at about $53. That alone is six to seven times a $7 recovered lead. But the sticker price isn’t the real number.

The real number comes from the resale. Shared leads are exactly that — shared. The same homeowner’s inquiry gets sold to four or five contractors at once. So the moment you buy it, you’re one of five shops racing to the phone for a job only one of you can win. Play that out: if the lead costs $50 and closes one time out of the five shops who bought it, the platform collected $250 to produce a single booked job. You paid your $50 whether you won or lost, and four times out of five you lost.

That’s the quiet tax on the reseller model. You’re not paying for a lead; you’re paying for a lottery ticket on a lead, and the odds are set so the middleman wins every draw. Thumbtack, Angi, and HomeAdvisor are shared-lead resellers, and the resale is the whole business model, not a bug.

What retargeting costs on the other side

Now the other road. Retargeting doesn’t buy a name from a middleman — it re-warms a homeowner who already found your site on their own. You already paid for that visit once, through whatever ad or search brought them in. Retargeting just makes that visit keep working after the tab closes, showing your name to that same homeowner on the platforms they already scroll.

When one of those consented visitors becomes a recovered lead, it’s a flat $7, exclusive to you, and never resold. Nobody else bought it. You’re not racing four shops — you’re following up with someone who chose your site specifically. So the cost-per-booked-job math runs backwards from the shared model: fewer dollars in, and every dollar chases a homeowner who already leaned your way.

Put the two side by side and the gap is stark. A shared lead: $46–$53, sold five times, you win maybe one in five. A retargeted lead: $7, sold once, to a homeowner who came looking for you. Same booked job at the end. Wildly different acquisition cost.

”But the shared lead filled out a form”

The usual objection is that a shared lead is hotter because the homeowner actively requested quotes. Fair — but look at what they requested. A shared-lead form-fill is a request to be pitched by every shop the platform sells to. That homeowner is, by design, comparison-shopping five contractors and bracing for five phone calls. Their interest isn’t in you; it’s in the category.

A retargeting audience is the opposite kind of interest. These are homeowners who searched, clicked, and landed on your site — read your reviews, looked at your work, priced your service. That’s a preference, not a broadcast. Exclusive interest in one shop tends to convert better than diluted interest split five ways, which is why re-warming your own traffic often beats buying a name that four competitors are dialing at the same moment.

There’s a second, quieter cost to the shared model that never shows up on the invoice: what it does to your close rate over time. When four of every five shared leads go to a competitor, your team learns — correctly — that most of these names are dead ends. So they call with less energy, follow up less, get worn down by the losing streak. The lead quality problem becomes a morale problem, and a demoralized shop closes even the winnable ones at a lower rate. Retargeting your own audience runs the opposite way: because these homeowners already chose you, more of the conversations go somewhere, and a team that wins more calls harder on the next one.

A worked example, one trade at a time

Make it concrete with a plumbing shop spending $500 a month on leads. On the shared model, that’s roughly ten leads at $50 each. Of those ten, the same names are being worked by four other plumbers, and if the shop closes two of the ten, it paid $500 for two jobs — $250 in acquisition cost per booked job, before a single truck rolls. That’s the honest number, not the $50 sticker.

Now take the same shop’s website, which already gets a few hundred visits a month from its ads and search presence — visits it’s already paying for. Most of those visitors leave anonymous today. Recover even a modest slice of them through consent-first retargeting at $7 each, and the same $500 reaches far more warm homeowners, each one exclusive, each one already leaning toward the shop. The acquisition cost per booked job doesn’t creep down — it drops by a wide margin, because you stopped paying a premium to lose a five-way race and started paying a little to finish conversations you were already halfway through.

Where retargeting fits — and where it doesn’t

Honesty matters here, because I spend a lot of time telling contractors what not to buy. Retargeting isn’t a magic replacement for demand. It can only re-warm people who already visited your site, so it scales with your traffic, not past it. If almost nobody visits your site, retargeting has little to work with, and you may still need Google LSA or search ads to create the first visit. Retargeting complements those channels — it makes the visits they produce pay off more than once — rather than replacing them.

What it does replace, for most shops, is the reflex to plug every gap by buying more shared leads. That reflex is the expensive one. Before you send another $50 to a reseller for a name four rivals also bought, it’s worth asking whether the cheaper booked job is already sitting in the traffic you paid for last week.

Run your own numbers

• Price your current shared leads honestly. Take the per-lead cost, divide by your real close rate on them, and you’ve got your true cost-per-booked-job. It’s higher than the sticker.
• Count the visits you already waste. Most home-service sites let the majority of visitors leave anonymous. Those are retargeting candidates you already paid to attract.
• Compare the two paths on the same page. The channel-by-channel math lays shared-lead pricing next to recovering your own traffic, with every figure sourced on our stats page.
• Point existing ads at existing visitors. Retargeting reuses your budget instead of adding to it, and the recovered lead stays $7 and exclusive.

The booked job is the same either way. One path pays a middleman $50 for a name sold five times; the other pays $7 for a visitor who already chose you. When you’re deciding where the next marketing dollar goes, that’s the comparison that actually matters — and instant retargeting is how you work the cheaper side of it.
