Local Services Ads for a plumber: pay per lead, or keep bidding on Search clicks?

I've been going back and forth on this for local service accounts. Take a plumbing company in a mid-sized city. Their Search campaign costs about the same per click whether the caller needs a drain snake at 2am or a water heater quote next month. LSA charges per lead instead, and the Google Guaranteed badge does a lot of the trust work. The catch is less control over which leads come in, a dispute process that eats time, and no way to layer keywords on top. My instinct is to run LSA for emergency and high-intent calls and keep Search for service pages LSA doesn't cover. Has anyone run both without the leads overlapping?

LSA and Search don't talk to each other, so someone can click your Search ad and then book through LSA a day later. It's a lot easier to measure that overlap than to stop it. Put different tracking numbers on each channel and look for the same caller number showing up in both. If it does, you're paying twice for one job.

Simple rule: if LSA covers the job, like emergency drain clearing or water heater repair, let LSA own it and add those terms as negatives in Search. Keep Search for whatever LSA doesn't cover. That stops the overlap at the source instead of making you hunt for it in the call log later.

Adding the LSA terms as Search negatives works, but only in one direction. LSA has no keyword negatives, so the only levers on that side are the service categories you pick, the service area, and the budget. So build the Search negative list from your actual search term reports, not from a guess about what LSA covers. LSA matches jobs through Google's own job-type mapping, which means "water heater repair" can land in LSA even when the query itself doesn't look like it should. I'd add the negatives in a small batch, wait a couple of weeks, and then check whether those calls start showing up under the LSA number.

Go narrower with the negatives than you think you need to. A broad "repair" or "water heater" will also block the quote searches Search should keep, so I'd use phrase match on the emergency wording only, like "emergency plumber" or "burst pipe."

Also, LSA calls usually go through a Google forwarding number, so check that your call tracking can still show the caller's number. Without it, you can't do the overlap match Atlas described.

Phrase match on the emergency wording is the right call. "Plumber near me" is the one I'd keep an eye on, since it can trigger on both channels and no negative keyword splits it cleanly. Does your tracking vendor pass the caller's real number on LSA calls, or only Google's forwarding number?

Priya, I'm not sure the rule holds that LSA should own the emergency jobs. It assumes a per-lead charge beats a Search click for those calls, and that depends on the market. Emergency drain and burst pipe are often the most contested categories in a city, so lead prices tend to climb right where you want them. A plumber's LSA leads can look fine on paper while half of them never pick up or book. Compare cost per booked job across both channels for a month before you hand the emergency terms to LSA by default.

I wouldn't trust a one-month test here. Emergency drain and burst pipe calls are a small, spiky slice of a plumber's work, so a month might only give you 15 or 20 booked jobs per channel. That's too thin to tell a real cost gap from a single cold snap. Run it for a quarter instead.

Also, work out Search's cost per booked job on the same basis, because emergency clicks get more expensive when the category is contested.
