A data-driven breakdown of when to use each platform — and why most businesses should be running both.
Every week, a business owner asks us some version of the same question: 'Should I be running Google Ads or Facebook Ads?' It's the wrong question — but it's an understandable one. Most small businesses have a limited budget and need to choose where to start. The right answer depends on your business model, your sales cycle, and whether your customers know they need you before they find you.
Google Ads is demand capture. When someone searches 'emergency AC repair Houston' or 'personal injury lawyer near me,' they already know they have a problem and they're actively looking for a solution. Google Ads puts you in front of that person at the exact moment of intent. The conversion rates are high because the intent is high.
Meta Ads (Facebook and Instagram) is demand creation. You are interrupting someone who was scrolling through their feed — they weren't looking for you. The job of a Meta ad is to create awareness, build desire, and move someone from 'I didn't know I needed this' to 'I want this.' Conversion rates are typically lower, but the audience reach is vastly larger and the cost per impression is much cheaper.
Google Ads is the right starting point for businesses where customers search for a solution when they have an urgent or specific need. This includes most service businesses: HVAC, plumbing, roofing, legal services, medical practices, auto repair, pest control. If your customer is likely to Google something when they need you, Google Ads is where your budget should go first.
Meta Ads is the right platform when your product or service requires education, when your customer doesn't know they need you yet, or when you're selling something aspirational or lifestyle-oriented. It's also extremely powerful for retargeting — showing ads to people who have already visited your website or engaged with your content.
The most effective digital marketing strategies we build use both platforms in a coordinated system. Google Ads captures the people who are actively searching. Meta Ads builds awareness and retargets the people who clicked on your Google Ad but didn't convert. The two platforms feed each other — and the combined effect is significantly greater than either one alone.
A roofing company we work with runs Google Ads to capture storm-damage searches and Meta Ads to retarget website visitors with before/after photos and customer testimonials. Their cost per acquired customer dropped 34% after implementing the combined strategy.
If you have a limited budget and need to choose one, start with Google Ads if you're a service business with clear search intent. Start with Meta Ads if you're selling a product or service that requires visual storytelling or education. But if your monthly budget is $3,000 or more, running both platforms in a coordinated strategy will almost always outperform putting everything into one.
The most important thing is not which platform you choose — it's having a clear measurement framework in place before you spend a dollar. Know your cost per lead, your lead-to-customer conversion rate, and your customer lifetime value. Without those numbers, you're flying blind regardless of which platform you're on.
