"How much should I spend on Google Ads?" is the first question almost every South Florida business owner asks. The honest answer is that the budget matters less than how it is split. This article uses real numbers from a Broward County account to show why.
The data comes from LuxeWash, a mobile detailing and ceramic coating business in Broward. Disclosure: LuxeWash is owned by Digital Anchor. We use it as our testing ground, which is why we can publish the account exports. The full write-up is in the LuxeWash case study.
The two costs of Google Ads
- Ad spend, paid directly to Google. You pay per click, and the price of each click is set by an auction.
- Management, paid to whoever builds and runs the campaigns. In South Florida this typically runs $500 to $1,500 per month for a small business, or a percentage of spend. Our Google Ads plans are $400, $997 and $1,997 per month.
Cost per click in home services varies widely by trade. Emergency trades such as plumbing, water damage and locksmiths sit at the expensive end; cleaning, detailing and handyman work are usually cheaper per click. What you really care about is cost per lead: what you pay, in total, for a call or a form from someone who wants the service.
What the Broward data shows
| Metric | Result |
|---|---|
| Cost per lead, best-performing city | $53 |
| Spread in cost per lead, best vs worst city (same ads, same landing page) | 71% |
| Cities shut off for zero conversions | 5 (Miramar, Tamarac, Sunrise, Coral Springs, Cooper City) |
| Search impression share lost to budget | 0.06% |
| Search impression share lost to rank | 54.34% |
| Click-through rate | 5.31% |
Lesson 1: the city matters more than the budget
The same ad, the same offer and the same landing page produced a 71% difference in cost per lead depending on the city. A single campaign for "South Florida" would have averaged that away and kept paying for the worst cities. Splitting campaigns by city made it visible, and five cities were turned off entirely.
Lesson 2: more budget would not have helped
Only 0.06% of impressions were lost because the budget ran out. More than half were lost because of ad rank, which Google calculates from your bid and the quality of your ad and landing page. Raising the budget would have changed almost nothing. Improving ads, landing pages and bids was the lever. Many South Florida accounts we audit have the same pattern: the owner thinks they need to spend more, and the account is actually losing on quality.
Lesson 3: tracking decides everything
None of this is visible without call tracking and conversion tracking set up correctly. We also found a Meta pixel that had silently failed for weeks, a reminder that tracking has to be checked, not assumed.
What budget should a South Florida service business start with?
A practical rule: you need enough clicks per city, per month, to see which cities convert. For most home-service categories that means roughly $1,500 to $3,000 per month in ad spend across 3 to 6 cities in the first 60 days. With less, focus on fewer cities rather than spreading thin. Once the data shows where leads are cheapest, scale those cities first.
| Monthly ad spend | What it realistically supports |
|---|---|
| Under $1,000 | 1 or 2 cities, one core service, strict negatives |
| $1,500 to $3,000 | 3 to 6 cities, city-level testing, 2 to 3 services |
| $3,000+ | County-wide coverage split by city, remarketing, seasonal pushes |
Five ways South Florida accounts waste money
- One campaign for the whole metro. Miami-Dade, Broward and Palm Beach behave differently. So do cities within Broward.
- Broad match without negatives. Searches for jobs, DIY, courses and cheap alternatives eat budget fast. See our keyword and negative keyword list for an example.
- Sending clicks to the homepage. A dedicated landing page per service converts better.
- Ignoring Spanish-language searches in a bilingual market, where relevant to your customers.
- Judging by clicks instead of booked jobs.
Ads, SEO or both?
Google Ads produces leads within days; SEO takes months but lowers your cost per lead over time. Most businesses that grow steadily in Broward use ads to find the cities and services that convert, then build local SEO pages for those.
