Facebook Ads vs. Google Ads for eCommerce in 2025: Which Should You Prioritize?

If you’re running an eCommerce brand in 2025, chances are you’ve asked this at least once:

“Should we invest more in Facebook Ads or Google Ads?”

It’s a fair question—and not a simple one. Both platforms have matured. Both can drive serious revenue. But they work in fundamentally different ways.

Choosing the right channel isn’t about which is “better”—it’s about which aligns with your product, offer, margin, and buying journey. And in some cases, the answer might be “you need both—but in very different roles.”

This post breaks down how Facebook Ads and Google Ads stack up in 2025—what each is best at, where they fall short, and how to prioritize based on your goals.

Facebook Ads: Interruption That Converts

Let’s start with Facebook (and Instagram, since they're part of the same ad system). Facebook Ads are discovery-driven. You’re not waiting for someone to search—you’re putting your brand in front of people who didn’t even know they needed you… yet.

Strengths:

???? Top-of-funnel reach: Perfect for getting eyes on new products
???? Creative flexibility: Video, UGC, Reels, Stories, Carousels
???? Advanced targeting: Interests, behaviors, lookalikes, custom audiences
???? Full-funnel structure: Awareness, retargeting, conversion, post-purchase
???? Mobile-native: Optimized for scroll behavior and impulse buying

Weaknesses:

❌ Purchase intent is lower: You’re catching attention, not solving a specific problem
❌ Requires great creative: Bad visuals = wasted spend
❌ Attribution is murky: Especially with post-iOS 14 tracking changes

Best for:

New product launches
Subscription or consumable products
Impulse-friendly D2C offers
Brands with strong visual identity and creative testing ability

Performance-first agencies like QuickAds’ Facebook Ads Agency specialize in maximizing Facebook's creative-first potential, especially for eCommerce brands looking to scale top- and mid-funnel fast.

Google Ads: High-Intent Performance Engine

Google Ads (including Shopping, Search, and Performance Max) are intent-driven. Someone types in what they want—and your ad shows up as the answer.

Strengths:

???? Captures bottom-of-funnel demand: Users are ready to buy
???? Shopping Ads are visually optimized for product searches
???? Great for branded search & competitor conquesting
⏱️ Fast time to first conversion if the funnel is clean
???? Strong attribution & analytics

Weaknesses:

❌ Creative is limited (except on YouTube or Display)
❌ No impulse-buy potential — you’re only catching people who already want something
❌ CPCs can be brutal in competitive categories
❌ Harder to differentiate your brand in a sea of text ads and pricing comparisons

Best for:

Search-heavy categories (tech, wellness, health, home goods)
Repeat products with branded demand
High-intent queries (“buy electric toothbrush online”)
Brands that already have demand—but want more efficient conversions

Facebook vs. Google: Head-to-Head by Objective

Objective	Winner
Product Launch / Brand Awareness	✅ Facebook Ads
Capture Purchase Intent	✅ Google Ads
Retargeting Abandoned Carts	✅ Facebook Ads
Branded Search Protection	✅ Google Ads
Storytelling / Product Education	✅ Facebook Ads
Fast ROI on High-Intent Keywords	✅ Google Ads
Creative Testing & Hook Iteration	✅ Facebook Ads
Local Services & Store Visits	✅ Google Ads
Building Email/SMS List (Lead Gen)	✅ Facebook Ads
High-Margin Products with Broad Appeal	✅ Facebook Ads

What About Performance Max?

Performance Max (PMax) is Google’s all-in-one smart campaign system. It mixes Search, Display, YouTube, Gmail, and Shopping.

It can work really well for eCommerce—but it's a black box. You get results, but you don’t always know which placements or keywords are driving what.

It’s great if:

You have a large catalog
Your conversion tracking is solid
You’re okay with less control in exchange for more reach

It’s risky if:

You don’t have enough creative assets
You’re launching something new without existing demand
You care about transparency and segmentation

So, Which Should You Choose?

If you’re just starting out:

Start with Facebook Ads if you:

Have a visual product with wide appeal
Are launching something new
Want to test creatives quickly
Need to build awareness + leads fast

Start with Google Ads if you:

Sell products with existing demand
Want to target high-intent keywords
Have strong profit margins to handle CPCs
Already get branded search traffic you want to monetize

If you’re already running both:

Use Facebook for top and middle funnel
Use Google for bottom funnel and branded capture
Connect both platforms using UTM tracking, server-side attribution, or post-purchase surveys

Real-World Example: Skincare Brand Funnel

Let’s say you’re launching a new anti-acne serum.

Facebook TOFU: UGC ad — “I struggled with acne for 5 years… then this changed everything.” → Leads to skin quiz
Facebook MOFU: “Dermatologist-tested, results in 7 days” + testimonial carousel → Leads to product detail page
Google BOFU: Search campaign for “best anti-acne serum” + Shopping ads + branded keywords
Retargeting: Facebook + Instagram cart-abandon ads, Google display remarketing

This cross-platform approach brings in new attention, nurtures it, and then closes with intent.

Final Verdict: Use the Platform That Matches the Customer Journey

The best eCommerce brands in 2025 aren’t choosing between Facebook and Google—they’re mapping each one to where it fits in the buying journey.

Facebook = spark the desire
Google = capture the intent

If you’re only using one, you’re leaving money (and customers) on the table.
