If you run a home-services or local business and you have never spent a dollar on Google Ads, the question gnawing at you is simple: will this actually pay off, or am I about to light money on fire? The honest answer is that paid search is one of the most measurable bets a local business can make, and the industry research points in a reassuring direction.
Here is the thesis, stated plainly: a well-run first Google Ads investment should not only return your spend, it should return a profit you can see and verify. That is not a promise of overnight riches. It is what the benchmarks suggest when the basics are done right.
The baseline return is better than most owners assume
Google's own economists, using a methodology developed by chief economist Hal Varian for its Economic Impact report, estimate that businesses earn roughly $2 in profit for every $1 they spend on Google Ads. Treat that as the optimistic end of the range, since it comes from Google itself, but it sets a useful frame.
Independent data lands in the same neighborhood. WhatConverts reported in 2025 that the average Google Ads return on ad spend is about 2:1, or 200%, with many businesses targeting 3:1 or higher. So a sensible first-year expectation is to roughly double your money, with room to climb as you tighten things up.
Local services tend to do better than average
Averages hide the good news for your category. Higher-margin home and local-services verticals often see blended ROAS in the 3:1 to 8:1 range, according to industry benchmarks. The reason is structural: a single booked job in HVAC, roofing, or plumbing is worth hundreds or thousands of dollars, so it does not take many conversions to cover the cost of the clicks that produced them.
There is a demand tailwind too. WordStream estimates that about half of all Google searches carry local intent — people looking for a service near them, right now. That is precisely the moment a local business wants to be the first name on the page.
What the numbers cost going in
Returns are only half the equation. You also need to know what you are paying. The 2025 WordStream benchmarks put the average cost-per-click around $5.26 and the average cost-per-lead around $70.11.
Run that math against your own economics. If a lead costs you about $70 and a meaningful share of leads become jobs worth several hundred to several thousand dollars, the gap between cost and value is wide. That gap is exactly where your ROI lives.
How much should you actually budget?
A common starting point: industry data shows local businesses typically invest 5 to 10% of revenue in digital marketing. For a $2M operator that is roughly $100k to $200k a year across all channels, of which paid search is one slice.
You do not have to start there. The smarter first move is to commit enough budget that the campaign can gather real data, then scale based on what the numbers tell you rather than guessing in advance.
What this means for your first investment
Put it together and the picture is clear. The averages point to doubling your money, your vertical likely beats the average, half of search demand is local, and the cost per lead is small relative to the value of a booked job.
The real risk in paid search is not the channel. It is running it without measurement — spending without ever closing the loop from a click to a booked job to revenue. If you can see that loop, the first investment stops being a gamble and becomes a decision you can make with numbers in front of you.
