Most electrical searches are small. An outlet died, a breaker keeps tripping, a fan needs hanging. Those calls fill the day and pay the crew, and they convert quickly. But the money in a modern electrical account sits in three specific clusters that behave completely differently: panel upgrades, EV chargers, and whole-home generators or battery backup. Each is a planned purchase, each has its own search language, and each is worth many times a service call.
The mistake is letting service-call volume swamp the reporting. A campaign that mixes everything shows a low cost per lead and a healthy call count while quietly failing to win a single panel upgrade, because the budget is being consumed by cheaper clicks with better click-through rates. Splitting them out costs nothing and immediately shows which parts of the business the advertising is actually feeding.
