Plumbing leads Sydney: cost per lead down 41.96%

Nobody shops around with water on the floor

Aussie Plumbing runs a 24/7 emergency operation across Sydney — blocked drains, hot water, burst pipes, the jobs that cannot wait until Monday.

Plumbing is the most expensive lead category in Australian search, and the reason is not complicated. The customer has water where it should not be. They are not comparing quotes. Every plumber in the city knows both of those things, so the clicks get bought at emergency prices.

The wrong enquiry costs the same as the right one

A plumbing business can carry a high cost per lead as long as the leads are the right jobs. What it cannot carry is emergency pricing on tenants who are not able to authorise work, addresses well outside the van's range, or people after a free diagnosis over the phone. Those three cost exactly as much to buy as a burst main ten minutes down the road.

In the earlier of the two periods reported here, the account was paying $117.75 for every enquiry. At that number, a very high share of the calls has to end in invoiced work before the channel makes any sense at all.

There is a second cost nobody puts in a spreadsheet. A plumber who drives forty minutes to a job that was never going to be booked has not just lost the lead fee. He has lost the afternoon, and the customer who rang while he was out there rang somebody else.

Running around the clock makes it harder, not easier

A 24/7 operation sounds like an advantage in search, and it can be. It also means the account is buying attention at hours when the person typing is least likely to be a paying job — the 2am scroller reading about why a drain gurgles, the tenant who wants to know whether the landlord has to pay.

Sorting the 2am panic from the 2am curiosity is not something you set up once. It is a habit, and it is the difference between an emergency plumber who dreads the ad account and one who checks the phone in the morning expecting work.

What we took on

Three campaigns, run hard and run tight, with every month that carried spend solid enough to judge honestly. The periods named below are ones we picked out and left undated. Taken over the whole account rather than one window, it has served 165,146 impressions, taken 8,130 clicks and produced 985 enquiries including 231 phone calls.

The rebuild pointed the account at enquiries that end in booked work rather than the ones that merely look like demand. Ads were written to the specific job — a blocked drain at 9pm is a different conversation from a hot water replacement someone is getting three quotes on. Underneath that, the reading never stopped: what people searched before they rang, and whether the business was paying emergency rates for calls a plumber would not want. The largest of the three campaigns delivered 735.5 enquiries at $78.83 each over the wider account.

None of that is glamorous and none of it happens in a single sitting. It is somebody going through what real people typed, deciding which of those searches deserved to cost the business money, and doing it again the following week because the mix never stays still for long.

Cost per lead fell 41.96% in the month volume peaked

The earlier period was the expensive one at $117.75 per enquiry. The next came back to $68.34, a fall of 41.96%, and it did that while producing the most enquiries the account has recorded: 247 in 31 days, from 1,488 clicks, at a 16.6% conversion rate, including 56 phone calls.

247 enquiries in that one period — roughly eight a day landing with the office, every day, for the whole month.

That combination is the genuinely hard one to pull off. Cost per lead normally falls because you bought less of everything. Volume normally climbs because you paid more. Here both moved the right way at once, which is what tells you the account changed rather than the budget.

• $117.75 → $68.34 cost per lead, one measured period to the next in 2026 — a 41.96% drop
• 247 enquiries in a 31-day period in 2026, the strongest month the account has had
• 16.6% conversion rate in that same period, from 1,488 clicks and 31,361 impressions
• 56 phone calls in that same period
• 985 enquiries and 231 phone calls across the account's wider run, at an average of $88.04 each
• 4.92% click-through rate and a 12.12% conversion rate on the same account-wide basis

What it meant for the business

Eight enquiries a day is a scheduling problem, which is the good kind of problem for a plumbing company to have. Enough to keep vans moving. Enough to be choosy about which job gets taken first when two land inside ten minutes.

The 12.12% conversion rate across the wider account is the underlying health check. Better than one in nine of the visits the business paid for became a tracked enquiry, in a category where plenty of accounts are buying expensive curiosity and calling it demand.

Cheaper leads also change what is worth chasing. Jobs that were marginal at $117.75 — the ones you would rather not send a van across the city for — start paying their way at $68.34. And the 231 phone calls are the part an office manager feels directly: somebody with a problem right now, on the line, instead of a form sitting unopened until morning.

The single biggest campaign is the clearest illustration. It produced 735.5 enquiries at $78.83 each over the wider account, which is most of the output sitting well under that earlier figure. Whatever else moved, the bulk of the work was being bought at a price the business could live with.

Volume then held rather than spiking and collapsing. The 247 enquiries were the peak, and the months either side of that period stayed in the same territory rather than falling back to where the account started. For a business that has to roster on-call staff, a floor is worth as much as a record.

If the phone is quiet on a Tuesday afternoon and the ad spend does not seem to be fixing it, that is usually an account problem rather than a market problem. Send yours over. We are happy to look and tell you either way, and we will point at the specific enquiries that were never going to become jobs.
