Google Ads vs Facebook Ads for Small Business
"Should I run Google Ads or Facebook Ads?" is one of the most common questions a small business owner faces, and the honest answer isn't "whichever is cheaper." The two platforms do fundamentally different jobs. Choosing well comes down to understanding one distinction: intent versus discovery.
The core difference: intent vs. discovery
Google Ads captures existing demand. When someone searches "emergency plumber near me" or "best CRM for small teams," they're actively looking for a solution right now. Google lets you put your business in front of that person at the exact moment they want what you sell. You're not creating the demand, you're capturing it.
Facebook Ads (and Instagram) create demand. Nobody opens Facebook looking to buy your product. They're scrolling. Your ad interrupts that scroll and introduces something they didn't know they wanted, based on who they are and what they're interested in. You're generating demand, not capturing it.
That single difference drives almost every other decision.
When Google Ads is the better fit
- People actively search for what you offer (services, urgent needs, specific products).
- You want high-intent leads or sales and can afford a higher cost per click for people ready to act.
- Your product solves a problem people know they have and go looking to fix.
When Facebook Ads is the better fit
- Your product is visual, impulse-friendly, or something people don't know to search for.
- You want to build awareness and reach a specific audience by interests, demographics, or behavior.
- You have compelling creative, images and video, since the ad has to earn attention it wasn't given.
Why many small businesses end up using both
The two platforms aren't really competitors, they cover different stages of how people buy. A common pattern: use Facebook and Instagram to create awareness and introduce your product to the right audience, then use Google to capture the people who, later, search for you or your category by name. Discovery on one platform feeds intent on the other. You don't have to run both from day one, but understanding that they're complementary keeps you from concluding that one "doesn't work" when it was simply doing a different job than you measured it against.
Start with one, judged on the right metric
For a small budget, it's usually smarter to start with one platform, the one that matches where your customers are, and give it enough budget to gather real data before splitting your attention. Judge Google on cost per lead or sale and intent quality; judge Facebook on reach, engagement, and demand created. Using the wrong yardstick is the most common reason a business abandons a platform that was actually working.
