A skincare brand at $390K/year was running only Meta at 2.7 ROAS with $12K/month spend. They added Google Shopping at $3K/month. Google hit 5.1 ROAS in 6 weeks — on buyers who were already searching for what they sold. The question wasn't "Meta or Google." It was "what job does each platform actually do, and which job is the constraint right now?"
The Wrong Question (and the Right One)
Most brands frame this as a competition: Meta vs Google, which is better? The comparison misses how the two platforms work.
Meta is a demand creation platform. It shows products to people who weren't looking for them. The job is to interrupt someone's scroll with something compelling enough to make them want it. Cold traffic, discovery, brand building.
Google is a demand capture platform. It shows products to people who are actively searching. The job is to be visible when someone types "moisturiser for dry skin shopify" or "home gym equipment." They're already in buying mode.
Asking which is better is like asking whether a net or a fishing rod is better. They catch different things.
Platform Fit by Product Category and Margin
Some products are more Google-native. Some are more Meta-native. And most should run both.
Google-native products: supplements, home goods, fitness equipment, pet supplies, kitchenware. People search these categories with intent. "Best magnesium supplement Shopify" has clear purchase intent. Google Shopping captures it at low CPCs. If you're in one of these categories, the Google Shopping feed and title optimisation guide is where to start.
Meta-native products: fashion, beauty, accessories, lifestyle products. Discovery matters. A new sunglasses brand doesn't get found through search — people don't know to look for it yet. Meta creates demand. Google captures it later.
High AOV products ($120+): Almost always perform better on Google Shopping as the front-end channel. The buyer researches before purchasing. A $180 cookware set gets searched, compared, and bought. Meta can warm the audience, but Google closes it.
Impulse products ($15–$45): Meta often outperforms Google for these. The low price threshold reduces friction enough that a well-matched ad converts cold traffic without a research phase.
When to Start With One vs Both
At $200K–$400K/year revenue with a single paid channel, the decision depends on the product type:
If you're in an intent-driven category (supplements, home goods, pet, fitness) and not on Google Shopping, that's likely the higher-priority add. Google Shopping with a clean feed and correct product titles at $3K–$6K/month often outperforms Meta at the same budget in intent-driven categories.
If you're in a discovery-driven category (fashion, beauty, lifestyle) and not on Meta, start there. Search volume for your specific product may be too thin for Google to generate meaningful scale.
If you're already on both but Meta is 90%+ of budget: that's a concentration risk. CPM increases on Meta during Q4 or after iOS changes don't affect Google. Diversification protects revenue.
The Decision Framework: 4 Criteria
Run through these to determine where to add or shift budget:
1. Search volume for the product. Go to Google Keyword Planner and search your top 5 product keywords. If combined monthly search volume is under 5,000, Google Shopping will struggle to spend meaningfully. Meta is the primary channel.
2. AOV and margin. If AOV is below $40 and gross margin is below 55%, Google's CPC structure often doesn't support profitable acquisition. Meta's CPM model is more favourable at low AOV.
3. Return rate. Google Shopping buyers tend to have lower return rates than Meta cold buyers (4–6% vs 11–18% depending on category). If returns are hurting your CAC, Google buyers are often cleaner. Also worth noting: Google Ads attribution inflates ROAS by 12–22% — reconcile with Shopify before making channel allocation decisions.
4. Creative capacity. Meta requires ongoing creative production. If you can't produce 2–3 new creatives per month, Meta ROAS will decay within 6–8 weeks. Google Shopping is feed-driven — creative isn't the constraint. If production is thin, start with Google.
