In the world of plumbing, questions about “clogged pipes” are usually easier to answer than questions about “clogged marketing funnels.” Recently, Tyler Williams, the founder of Mammoth Marketing, sat down with a plumber who was tired of the digital grind. This business owner, a veteran of the trade who handles everything from routine maintenance to emergency “my basement is a swimming pool” calls, had a burning question:
“Tyler, should I just stop doing Google Search ads entirely and move everything over to Local Service Ads?”
It is a logical question to ask. On the surface, the proposition sounds like a dream come true for any contractor. Why pay for a click from a window-shopper or a competitor “checking out the site” when a company can pay for actual, tangible leads? However, as Williams often reminds his clients, marketing is much like plumbing: if an old system is ripped out without understanding the underlying pressure, the result is usually a mess on the shop floor.
As the leader of Mammoth Marketing, Williams doesn’t believe in “general” marketing. The firm doesn’t spend time helping bakeries sell cupcakes or florists move tulips. They work with plumbers, and only plumbers. Because the Mammoth team lives and breathes the industry, they aim to pull back the curtain on the mechanics of these platforms to show how they truly function in a competitive landscape.
A Brief History of Google’s Quest for World Domination
To understand the current digital climate, Williams suggests looking back at where the industry started. For decades, the “massive yellow brick”, the phone book, was the only game in town. It sat under computer monitors or propped up short tables across the country. Then, Google arrived and changed the world.
Initially, Google was simply a highly efficient search engine. However, the tech giant eventually realized they needed a way to fund their massive server infrastructure, and Google Search Ads (PPC) were born. In those early days, plumbers who adopted the platform early were essentially printing money. Competition was non-existent, and leads were remarkably cheap.
The game changed forever with the invention of the smartphone. Suddenly, every homeowner had a “phone book” in their pocket 24/7. Competition skyrocketed. As the Yellow Pages began to fade into obscurity, every local service company flocked to the digital world. As demand rose, Google transitioned to an auction system. This gave them the power to set price floors and watch the ceiling rise, often “throttling” the auction to meet quarterly revenue goals while the business owner was left holding the checkbook.
The Era of “Dominating Google” (And Why Google Hated It)
For a long time, the prevailing wisdom in marketing was total dominance. The goal was to occupy as much real estate on the search results page as possible: the top PPC ad, the top Map Pack spot, and the top organic link.
For companies with massive budgets, commanding the page was easy. But Google noticed a problem. Just because a plumbing company has a massive marketing budget doesn’t mean they provide high-quality service. If Google referred a user to a plumber who paid for the top spot but then performed a “hack job” and overcharged, the customer didn’t just get mad at the plumber—they got mad at the “referee,” Google.
To protect their reputation and keep users from switching to other search engines, Google decided they needed more control. They needed to ensure they were recommending the “good guys.” This desire for quality control led to the birth of Local Service Ads (LSA).
What is LSA? (The “Google Guarantee” Magic)
Google introduced a brand-new inventory of ads that sit at the very top of the page—above even the traditional PPC ads. They branded this with a green checkmark and the words “Google Guaranteed.”
For plumbers, this was a game-changer. It provided an immediate trust metric. To earn that checkmark, a business must go through a rigorous vetting process. Google verifies insurance, conducts background checks on technicians, and confirms business and plumbing licenses. Essentially, Google is telling the homeowner, “We’ve checked these guys out; they aren’t scammers.”
The fundamental difference lies in the payment model: LSA is Pay-Per-Lead, while PPC is Pay-Per-Click. In the PPC world, a plumber might pay for 15 clicks—some from job seekers, some from competitors, and some from accidental taps—before getting a single phone call. With LSA, the plumber only pays when the phone rings or a message is sent. It sounds like a total win, but Williams warns that there is a significant “gotcha” involved.
The Budget Trap: Why LSA Won’t Always Spend Your Money
The “gotcha” that catches most plumbers off guard is the lack of a “spend lever.” With traditional PPC, if a company wants more leads, they simply throw more money at it. Google will happily show the ad more often as long as the budget is there.
LSA does not function this way. Google controls LSA volume based on “reputation signals.” They analyze reviews, response times, and the rate at which leads are converted into customers. Because Google wants to maintain the integrity of the “Google Guarantee,” they won’t let one company dominate the top spot just because they have a large wallet.
This is why Williams advises against moving an entire budget to LSA. A plumber could set a $10,000 monthly budget, but Google might only decide to spend $2,000 of it based on their internal metrics. If the plumber cut off their PPC ads, they would lose out on $8,000 worth of potential leads. The trucks would stay empty, and the technicians would be sitting on their hands.
The “Roll-Over” Strategy: Balancing the Two
Instead of a total switch, Mammoth Marketing recommends a methodology that treats the marketing budget as a living, breathing asset. Williams suggests that plumbers should not simply split their budget 50/50 and walk away. Instead, they should follow this tiered approach:
Prioritize LSA: Set the LSA budget to a healthy level. Since the cost per acquisition is often lower, the goal is to take as many of those leads as Google is willing to provide.
The Weekly Check-In: Monitor the actual LSA spend regularly.
The Reinvestment Loop: If LSA hasn’t spent its full allotment by the end of the week, that “leftover” cash should be rolled immediately into Google Search (PPC) ads.
This strategy ensures that the company is constantly meeting market demand. Rather than hoping LSA “pops off,” the plumber uses PPC as a reliable backstop to catch all the search volume that LSA misses.
Nurturing the LSA Beast
The Mammoth team emphasizes that LSA is not a “set it and forget it” platform. It requires constant feeding. To keep Google sending leads, plumbers must provide the right signals:
Marking leads as “booked” within the dashboard.
Requesting reviews specifically through the LSA platform.
Answering the phone every time it rings (missing LSA calls is the fastest way to be demoted in the rankings).
While PPC is about auction bids and keyword strategy, LSA is about reputation and responsiveness. Williams insists that a modern plumbing business needs both to win.
Avoid the “Big Swing” Mistake
A common mistake Williams sees with eager business owners is the “big swing.” They see LSA performing well for a few days and decide to kill their PPC entirely. Two weeks later, the LSA volume drops, and the phones go silent.
In marketing, Mammoth Marketing advocates for testing and verification. Major swings can put an entire company at risk. The shift from PPC to LSA should be a slow, data-driven transition. If LSA is consistently delivering, the budget can be nudged up, but a business should never leave itself vulnerable by putting all its eggs in one Google-shaped basket.
