Every year the same conversation happens in home improvement accounts. Cost per lead has gone up again, the market is blamed, and bids go up to compensate. A season later the same conversation repeats, from a higher base.
The problem is rarely the bid
Rising cost per lead is usually a symptom of counting the wrong thing. Most home improvement accounts optimise toward form fills and phone calls without distinguishing between a homeowner ready to book a survey and someone pricing a job they will not commission for two years. Google’s bidding does exactly what it is told: it finds more of whatever you called a conversion, and the cheapest version of that is almost always the least committed enquiry.
Once low-intent enquiries dominate the conversion data, the algorithm optimises toward them, the sales team wastes hours qualifying, and the apparent cost per lead looks fine while cost per booked job quietly climbs.
Count jobs, not enquiries
The single highest-leverage change in most home improvement accounts is feeding a later signal back into Google. A booked survey. A quoted job. Ideally, a signed contract with its value attached. This is unglamorous work — it usually means connecting a CRM and agreeing internally what counts — but it changes what the platform optimises toward.
Accounts that make this change often see reported cost per lead rise while cost per job falls. That looks alarming on a dashboard and is exactly the right outcome.
Decide which jobs you actually want
Not all work is worth the same. A full house rewire and a single socket replacement arrive through the same search interface but have wildly different margins. Campaign structure should reflect that: separate budgets for the job types you want more of, and genuine restraint on the ones you do not.
Negative keyword work matters here more than in almost any other sector. Terms containing DIY, cheap, repair, or second hand consistently attract enquiries that never convert into installations, and they are usually cheap enough that automated bidding finds them attractive.
What to change this quarter
Start by separating your conversion actions so survey bookings are counted apart from general enquiries, and set bidding to optimise on the former. Split campaigns by job value rather than by keyword theme. Then review search terms weekly rather than monthly — in a seasonal market, waste accumulates faster than most reporting cycles catch it.
