"I already tried Google Ads and it didn't work"
If you've ever said this, you're not alone. Many small business owners have invested in ads, seen no results, and concluded that "Google Ads doesn't work for my type of business."
Most of them were wrong. The problem is almost never the platform. It's the setup.
Why most campaigns fail
When you create a Google Ads campaign without experience, Google itself nudges you toward a setup that benefits Google — not your business.
The most common mistakes:
Audience too broad — advertising to all of Brazil when you only serve one neighbourhood or city. You pay for clicks from people who will never be your customers.
Wrong keywords — showing up for searches with no buying intent. "how to make a cake" versus "cake order [your city]" are completely different audiences.
Weak landing page — the ad sends people to the homepage or to Instagram. The customer clicks, doesn't find what they were looking for, and leaves. You paid for the click and got nothing in return.
No follow-up — setting up the campaign and forgetting about it. Google Ads needs constant adjustments to improve.
When Google Ads actually works
For small local businesses, Google Ads works really well when:
✓ The campaign is segmented by location (neighbourhood, city, radius of X km) ✓ The keywords have buying intent ("hire," "price," "near me") ✓ The ad leads to a specific page with a clear CTA ✓ There's weekly follow-up and adjustments based on the data
With this setup, a hair salon in São Paulo can show up exactly when someone in that neighbourhood searches "women's haircut price" — and only pay for that click.
How much do I need to invest?
There's no universal minimum amount. It depends on your market, your competition, and your goal. But the logic is simple:
If you earn R$150 per service and get 1 new customer a day from your ads, how much would you be willing to pay for that customer? R$10? R$20? R$30?
Google Ads works when the customer acquisition cost is lower than the value that customer brings to your business. And with good management, that's entirely achievable for small businesses.
The difference between doing it yourself and having professional management
Doing it yourself: possible, but you'll pay for the learning curve — in money lost on poorly configured campaigns and time spent learning a complex platform.
With professional management: the campaign starts off correctly configured, with local targeting, relevant keywords, and weekly follow-up. You focus on your business and receive clear reports on what's working.
Is it worth it for my business?
The honest answer: it depends. But the best way to find out is with a diagnosis of your current campaigns (if you have any) or an analysis of your local market's potential.
