The dirty secret of home services marketing is that no one actually knows if it works. Agencies produce reports full of call volume and click-through rates, clients nod along, and the money keeps flowing toward whichever channel generates the most legible-looking numbers. Alexander Law-Smith spent enough time studying this cycle to develop a firm opinion about it. That opinion, supported by three years of data across more than forty U.S. city markets, is that most of those numbers are proxies for performance rather than measures of it.
Law-Smith is the Director of Advertising and Digital Marketing at Fast Mold Testing, a San Francisco-based company that operates a national network of more than one hundred and fifty certified inspector partners across more than one thousand completed inspections. That footprint did not accumulate through referrals or reputation. It grew because Law-Smith built a paid acquisition system designed to measure the one thing most home services advertisers refuse to wait for: whether a dollar spent actually produced a completed job.
The problem is attribution. A Google ad generates a click, the click becomes a phone call, the phone call turns into a voicemail, and somewhere in that sequence the customer disappears, or books and cancels, or decides the whole thing can wait until spring. Most attribution systems declare victory at the call. Law-Smith’s does not. It waits for the completed inspection and works backward from there.

“ROAS is the only metric that matters in paid media for local services,” he said. “Everything else is a story you tell while the client’s budget disappears.”
The result is a 5.5x average return on ad spend maintained simultaneously across Google Ads, Local Services Ads, and Meta. For context: a 2x ROAS is functional. A 3x is something an agency prints on a slide. At 5.5x, sustained across forty-plus geographically distinct markets, the number cannot be explained by media buying instinct. It comes from a measurement architecture that is built to tell the truth about what is actually happening.
“Attribution is where most marketers lie to themselves and their clients,” Law-Smith said. “Not intentionally, but because they’ve never built a system honest enough to tell them the truth. The moment you actually connect ad spend to closed jobs, everything changes.”
The architecture itself is not exotic. It involves tagging inbound leads from each paid channel through to booking confirmation, cross-referencing against completed job records, and feeding the optimization loop with revenue data rather than with the proxy metrics that make dashboards look good. The discipline is doing this in a vertical where most operators are small businesses without engineering resources, and where the industry standard for performance measurement is still a monthly call report.
Law-Smith came to that discipline through an unusual path. Before FMT, he spent several years at Corporate Traveller managing business development accounts across South Australia and New South Wales. His portfolio included major defense and aerospace companies, and the annual travel spend he managed exceeded three million dollars. Clients operating at that scale, with travel logistics that do not tolerate ambiguity, tend to calibrate anyone they work with toward a strict relationship with accountability. The margin for creative reporting is zero.
Before Corporate Traveller, he was part of the founding team at Numuworld, where the mandate was velocity. The company signed thirty paid enterprise clients in its first month of operation and was past seventy within twelve months. The roster included Zambrero, the restaurant group with more than three hundred global locations, and Peregrine Corporation, one of South Australia’s largest privately held companies by revenue. Other early clients included Soonta and Brunelli, established multi-location operators in hospitality and retail. Acquiring accounts at that quality, without an established brand and across two Australian states simultaneously, required a repeatable process rather than a Rolodex.
The thread connecting Corporate Traveller, Numuworld, and FMT is not industry experience. It is a compulsive orientation toward outcomes over activity.
That assumption shapes the channel strategy at FMT in practical terms. Law-Smith runs three channels inside a single attribution system, each with different cost structures, different conversion behavior, and different competitive dynamics by market. Local Services Ads, for instance, surface above standard paid search results and carry Google’s verification badge. The conversion rate they produce relative to cost is measurably different from what a text ad generates. Most operators running both channels simultaneously have no clean way to compare them, because their attribution breaks before it reaches a completed transaction.
“Local SEO is the most underpriced distribution channel in business right now,” Law-Smith said. “Every dollar spent on Google Business Profile optimization compounds in a way that paid media never can.”
That observation points to the organic layer running underneath the paid system. FMT’s city-by-city visibility is supported not only by ad spend but by Google Business Profile health, review volume, and local search authority that accumulate over time. Paid acquisition fills the top of the pipeline while organic presence steadily reduces the long-run cost of keeping it full. Law-Smith designed the two to operate as a single system rather than as parallel strategies managed by separate teams.
Scaling that system across forty-plus markets without allowing the ROAS to degrade is where the complexity compounds. Each city has its own competitive conditions, its own search intent signals, its own cost-per-click floors and ceilings. A plumber in Phoenix and a mold inspector in Philadelphia do not compete inside the same auction environment. Maintaining an average return that holds across that geographic variation requires constant optimization against real revenue data from each market, not against aggregated numbers that smooth out the differences.
The system works because it was built to be honest about what it measures, and because the person running it spent formative years in business environments where dishonest measurement was never an option. Defense logistics clients do not accept vague reporting. Neither do fast-growing startups burning through their first year of enterprise sales.
For an industry where the standard of care is still a monthly call report and a thank-you email to the agency, that particular discipline tends to look like an anomaly. Law-Smith tends to describe it as the minimum.
