Do Google Ads work for contractors?
Yes, when three things are true: the searches you pay for are people ready to hire, the page they land on makes calling easy, and you answer the phone. Google Ads puts you at the top of the page the day you turn it on, which no other channel can do. That is why it is useful for a new business, a slow season, or a high-value job type you want more of.
Where it fails is when it is set up loosely. Paying for "roofing" instead of "roof repair Louisville," showing ads across the whole state, or sending clicks to a homepage with no phone number above the fold burns through a budget with nothing to show for it.
What does a click cost?
LocalIQ publishes benchmarks from thousands of real campaigns. In its 2026 search advertising benchmarks, the home and home improvement category averaged:
- $8.33 per click, against $5.42 across all industries
- 8.05% conversion rate, so about one click in twelve becomes a call or form
- $90.92 per lead, against $66.69 across all industries
Emergency trades like plumbing, HVAC and roofing usually sit above that average, because the jobs are worth more and more companies bid. Small towns usually sit below it. Treat $8 a click and $90 a lead as a starting point and expect your own numbers after the first month.
Is $20 a day enough for Google Ads?
It is enough to learn, not enough to rely on. Google bills against a monthly limit of 30.4 times your daily budget, so $20 a day is about $608 a month. At average home improvement rates that buys about 73 clicks, which at an 8% conversion rate is about six leads. If your average job is worth a few thousand dollars and you close one or two of those, it pays. If your jobs are small, it probably does not.
The bigger issue is that six leads a month is a thin sample. One bad week can make the whole thing look broken. If you test at $20 a day, give it at least two months and judge it on cost per booked job, not cost per click.
Is $100 enough for Google Ads?
As a total budget, no. At $8 a click, $100 is about a dozen clicks, which tells you almost nothing. As a daily budget it is a real campaign for one trade in one metro, roughly 365 clicks and about 29 leads a month at average rates.
Why did Google Ads charge me more than my daily budget?
Because Google treats your budget as a daily average, not a cap. According to Google's own help page on budgets, a campaign can spend up to twice its average daily budget on a busy day, but you will not be charged more than 30.4 times the daily budget in a month. A surprise charge is usually that, or the account hitting a billing threshold and charging the card in one go. If you need a hard cap, set a lower daily budget or an account spending limit.
