Google Ads captures existing demand. Facebook Ads creates new demand. The right choice depends on whether your buyers are searching for you or need to discover you first. Here’s how to decide.

This distinction affects everything: cost per click, conversion rate, creative requirements, and the timeline to ROI. Google Ads converts faster because the buyer is further along in their decision process. Facebook Ads costs less per impression but requires more touches before conversion. Neither is “better.” They serve different functions in your marketing system.Google Ads answers the question a buyer is already asking. Facebook Ads introduces a question the buyer hasn’t asked yet. Both work, but at different stages of the buying process and with different cost structures.
| Industry | Google Ads Avg CPA | Facebook Ads Avg CPA |
|---|---|---|
| E-commerce | $45 | $21 |
| B2B / SaaS | $116 | $65 |
| Education | $72 | $31 |
| Real Estate | $116 | $52 |
| Health & Fitness | $78 | $38 |
| Legal | $87 | $51 |
| Finance / Insurance | $90 | $43 |
| Business Type | Recommended Split | Why |
|---|---|---|
| B2B SaaS | 70% Google / 30% Facebook | High search intent, longer sales cycle, Facebook for retargeting only |
| DTC Ecommerce | 40% Google / 60% Facebook | Visual products, impulse purchases, Facebook’s catalog integration |
| Local Services | 80% Google / 20% Facebook | “Near me” searches are pure intent, Facebook for local brand awareness |
| Brand Awareness | 20% Google / 80% Facebook | No search demand yet, need to create awareness before capture |
| Lead Gen (B2C) | 50% Google / 50% Facebook | Both platforms generate leads; test and optimize by CPA and close rate |
“The Google vs. Facebook debate is the wrong question. Google captures demand. Facebook creates demand. If you only capture, you’re limited to today’s search volume. If you only create, you’re paying to educate people who might buy from a competitor. You need both engines running, and you need to track the interaction between them, not just each one in isolation.”

Facebook Ads has a lower average CPC ($0.77 vs. $2.69 for Google Search) and lower average CPA across most industries. However, Google Ads leads tend to convert to customers at higher rates because of search intent. Evaluate cost-per-customer, not cost-per-click. A $100 Google lead that converts at 10% costs $1,000 per customer. A $50 Facebook lead that converts at 3% costs $1,667 per customer.
Yes, and most businesses with $5,000+ monthly ad budgets should. Use Facebook for top-of-funnel awareness and retargeting. Use Google for capturing high-intent search demand. Track blended ROAS across both platforms in GA4. Companies running both typically see 10-20% lower blended CPA than those using either platform alone.
For most ecommerce brands, Facebook Ads drives more volume at lower CPA, especially for products under $100 and visually appealing categories. Google Shopping Ads are essential for capturing search demand and typically deliver higher ROAS on branded and product-specific searches. A 40/60 Google-to-Facebook split is a common starting point for ecommerce.
Start with $1,000-$2,000/month on a single platform to gather enough data for optimization (at least 30-50 conversions per month). On Facebook, you can start with $500/month for testing. On Google, $1,000/month is the practical minimum in most industries. Expect 2-3 months before you have enough data to optimize effectively. Don’t judge either platform on 2 weeks of data.
Apple’s App Tracking Transparency (iOS 14.5+) reduced Facebook’s ability to track user behavior across apps and websites, making targeting less precise and attribution less accurate. CPAs on Facebook increased 15-30% for many advertisers post-iOS 14. Google was less affected because search advertising relies on keyword intent, not cross-app tracking. Facebook has since improved its Conversions API and machine learning models to partially compensate, but the pre-iOS 14 targeting precision hasn’t fully returned.
