How Much Should a Local Service Business Spend on Google Ads?

“What should my budget be?” is the first question on almost every strategy call we take. The honest answer is that anyone who quotes you a number before asking about your business is guessing. But the way to work it out is simple enough to do on a napkin.

Start from the job, not the budget

Work backwards from three numbers you already know:

1. Average job value. What’s a typical signed job worth — $3,000 bathroom refresh, $15,000 foundation repair, $40,000 kitchen?
2. Close rate. Of the qualified leads that reach you, how many become customers? Most decent local operations land between 25% and 50%.
3. What a customer is worth paying for. If a job nets you $5,000 in profit and you close one in three leads, a lead is worth up to ~$1,600 to you — and anything you pay under that is margin.

Now the budget question becomes concrete: at your market’s real cost per lead, how many leads does your budget buy, and how many jobs is that? A $2,000/month budget in a market with $80 leads is ~25 leads — call it 6–10 jobs. If that math excites you, the budget is right. If it doesn’t, the problem is usually cost per lead, not budget size.

Why “just spend more” often fails

Clicks in local service niches aren’t cheap — foundation repair and legal clicks can run $30–$50 or more. At those prices, waste compounds fast:

• Wrong-intent clicks. “How to fix a foundation crack myself” costs the same as “foundation repair company near me”. Without an aggressive negative-keyword list, DIY researchers eat your budget.
• Leaky landing pages. Doubling spend on a page that converts 3% of visitors just doubles the waste. Fixing the page first can halve your cost per lead with the same budget.
• Slow follow-up. More leads you answer slowly are just more leads your competitor books. (We wrote about this: speed-to-lead.)

This is why we treat budget as the last dial, not the first. In one of our accounts, a roofing contractor got 61 exclusive leads in 30 days with a 25% lower cost-per-lead — the win came from targeting and conversion work, not extra spend.

A sane starting framework

• Testing phase (first 60–90 days): enough budget to buy roughly 10–15 clicks a day in your market. Below that, you can’t learn what works fast enough to improve it.
• Prove the math: track calls and forms to actual booked jobs. No exceptions — untracked spend is unaccountable spend.
• Then scale: once cost-per-job is known and profitable, raise budget in steps and watch that the number holds.

The one rule that matters

Never set a budget you can’t track to revenue. The businesses that win with Google Ads aren’t the ones that spend the most — they’re the ones that know exactly what a lead costs, what a job is worth, and cut everything in between that doesn’t connect the two.
