Introduction
Google Shopping remains the world's most powerful e-commerce acquisition channel. But in 2026, it's no longer equally profitable for everyone.
CPCs have increased 18-24% over 3 years in competitive categories. Amazon and major marketplaces dominate a growing number of generic product queries. And since Google launched its AI Mode, some shopping queries are being answered directly in AI responses — without clicks on ads.
The real question isn't "should you abandon Google Shopping?" — the answer is no for the vast majority of e-commerce merchants. The real question is: how to adjust your Google Shopping strategy in 2026 to maintain acceptable ROAS in the face of these changes, and when to diversify?
This article answers with data: average ROAS by sector, CPC evolution, AI engine impact on volumes, and strategic recommendations by merchant profile.

Google Shopping in 2026: The Numbers {#numbers-2026}
Traffic volume: Google Shopping still represents approximately 65% of shopping result clicks in major European markets. This figure hasn't significantly dropped despite the rise of alternatives.
CPC evolution: cost per click has increased an average of 18% between 2023 and 2026 in the most competitive categories (fashion, electronics, home). In less competitive categories, the increase is more moderate (8-12%).
Average Google Shopping ROAS 2026:
| Sector | Avg ROAS 2026 | Avg ROAS 2023 | Change |
|---|---|---|---|
| Fashion and clothing | 3.8x | 4.6x | -17% |
| Consumer electronics | 4.2x | 5.1x | -18% |
| Beauty and cosmetics | 5.1x | 5.8x | -12% |
| Home and decor | 4.7x | 5.3x | -11% |
| Sports and outdoor | 5.3x | 5.9x | -10% |
| Garden and outdoor | 6.2x | 6.5x | -5% |
| Food and specialty | 3.2x | 3.1x | +3% |
| B2B supplies | 7.1x | 7.4x | -4% |
| Toys and games | 4.1x | 5.0x | -18% |
ROAS is declining across nearly all sectors, primarily due to rising CPCs. But a ROAS of 3.8x remains positive for most e-commerce business models.
The real threat: Amazon and major marketplaces On generic queries like "bluetooth headphones," Amazon often occupies the top Shopping positions with very competitive pricing and massive review ratings. For independent stores, competing head-on on these generic queries is increasingly difficult — and expensive.
Strategic response: focus on specialized long-tail queries where Amazon is less present and your expertise is differentiating.
Sectors Where Google Shopping Remains Highly Profitable {#profitable-sectors}
Technically specific or configurable products: custom-made, dimension-configured, or personalized products are poorly served by marketplaces. Google Shopping remains the best channel because purchase intent is explicit and qualified, Amazon can't compete on customization, and high average order values amortize CPCs. Typical ROAS: 6-12x.
Local or delivery-constrained products: heavy products (furniture, large appliances, building materials) or fresh/regional products benefit from a localized audience on Google Shopping that national platforms can't easily serve.
Ultra-specialized niches: (diving, scale modeling, amateur astronomy) face less competition on specific queries with audiences willing to pay more for exactly what they need.
Own-brand products: selling under your own brand (no direct competitor on the same references) — Google Shopping is highly profitable as you don't suffer price competition on your own products.
Sectors Under Pressure in 2026 {#pressure-sectors}
Generic consumer electronics: queries like "smartphone," "PC monitor," "audio headset" are dominated by Amazon and major retailers with massive budgets. CPCs can exceed €1.50-2 on highly competitive queries. What still works: specific model queries, refurbished products, specialized accessories.
Generic fashion: queries like "summer dress," "men's jeans" are dominated by ASOS, Zalando, H&M. What still works: brands with a strong identity, products with specific searched attributes ("organic linen dress inclusive sizing"), independent creators with a loyal clientele.
Widely available commodity products: products available at all major retailers struggle to differentiate on Google Shopping.
The Impact of AI Engines on Shopping (GEO) {#ai-impact}
The structural change of 2026: a growing share of shopping queries flows through AI engines — Google AI Mode, Gemini, ChatGPT, Perplexity. Key figures:
- 12-18% of English-language queries go through AI interfaces in 2026
- Google AI Mode is now activated by default for some Google users
- "Which product to choose for..." type queries migrate massively to AI
What remains on Google Shopping: direct purchase queries with product and price ("buy [specific product]") stay on classic search → Shopping. These are the most transactional queries closest to purchase.
What migrates to AI: discovery and comparison queries ("best [product] for [use]", "which [product] to choose") migrate to AI. These previously fed the top of the Google Shopping funnel.
The GEO-GMC connection: the compliance criteria for Google Merchant Center — structured data, price consistency, image quality — are exactly the criteria that determine GEO visibility. A good GMC compliance score simultaneously improves Google Shopping performance AND visibility in AI engines. Audit both with MyGoogle.
When to Diversify Your Shopping Channels {#when-diversify}
5 signals that it's time to diversify:
- Google Shopping ROAS declining continuously for 3+ months — your market is becoming more competitive on Google
- CPC exceeding 15% of gross margin per product — the model becomes hard to profitably sustain
- 100% of Shopping revenue through a single channel — GMC suspension would paralyze all Shopping acquisition
- Primary audience is mainly 18-35 years old — this audience increasingly discovers products on TikTok and Instagram
- Products have strong visual/lifestyle dimension — discovery increasingly happens on visual surfaces
What diversification doesn't replace: diversifying channels doesn't replace Google Shopping optimization. Adding Meta Shopping Ads with negative ROAS doesn't compensate for a profitable but poorly-optimized Google Shopping. The logic: optimize GMC first, then diversify from a healthy base.
How to Optimize Your Google Shopping ROAS {#optimize-roas}
The 5 most effective optimization levers in 2026:
Lever 1: Feed quality — This is the #1 lever and the most underexploited. A feed with optimized titles (including key attributes: brand, material, color, use), rich descriptions, high-quality images, and complete structured data improves ad Quality Scores and reduces CPCs. Typical gain: improving feed compliance from 60% to 90% can reduce CPCs by 10-20% on the same queries.
Lever 2: Campaign segmentation by margin — Don't group products with very different margins in the same campaign. High-margin products can sustain higher CPCs.
Lever 3: Aggressive negative keyword exclusion — Generic queries dominated by Amazon drain budget without conversion. Add aggressive negative keywords to focus budget on queries where you have an advantage.
Lever 4: Custom Labels for promotions — Segment products in promotion, high-margin products, bestsellers, and new arrivals to apply differentiated bidding by context.
Lever 5: GMC compliance as Quality Score factor — Google uses GMC account compliance quality as a signal in Shopping ad Quality Score calculation. A well-compliant account (few disapprovals, complete structured data, compliant images) benefits from better placements for the same CPC.

GMC Compliance: The Forgotten Performance Lever {#compliance-performance}
Most Google Shopping advertisers think about bid and audience optimization — few think about GMC compliance as a performance lever.
Google uses several compliance signals in its Shopping ad ranking algorithm:
- Product data completeness: complete attributes (color, size, material, GTIN, brand) improve ad relevance and quality scores
- Structured data quality: pages with complete, consistent Schema.org Product/Offer get better placements
- Disapproval rate: an account with few disapprovals has a better trust score with Google
- Feed/page consistency: perfect consistency between feed and product pages is a reliability signal that favors placements
A concrete example:
- Monthly Google Shopping spend: €3,000
- Current average CPC: €0.60 → 5,000 clicks
- Conversion rate: 2.5% → 125 sales, €80 AOV → €10,000 revenue
By improving feed quality (compliance from 65% to 90%):
- CPC reduced 12% → €0.53 → 5,660 clicks (same budget)
- Conversion rate improved 0.3pt (better relevance) → 2.8% → 158 sales
- Revenue: €12,640 → +26.4% revenue for the same ad spend
This is a simplified calculation, but it illustrates the magnitude: feed quality and GMC compliance are underexploited performance levers with high leverage.
FAQ {#faq-en}
Is Google Shopping still profitable in 2026? Yes, for the vast majority of e-commerce merchants — but profitability depends more on sector, specialization, and feed quality than it did 3 years ago. Average ROAS has declined 10-18% depending on sector, mainly due to rising CPCs. Specialized sectors, own-brand products, and high-value-added products maintain very satisfactory ROAS. Generalist sectors competing with Amazon and major retailers are most under pressure.
Should you switch to Performance Max or keep standard Shopping campaigns? In 2026, Performance Max is generally recommended for large catalogs (100+ products) with sufficient conversion data (minimum 30-50 conversions/month for AI learning). Standard Shopping campaigns remain relevant for small catalogs, very specific niches, or when you need granular query control.
What minimum budget to start on Google Shopping in 2026? A minimum budget of €500-800/month is recommended to collect sufficient conversion data and allow the algorithm to learn. Below this threshold, learning is too slow and results uninterpretable. For Performance Max, budget €1,000-1,500/month minimum for effective learning.
Will AI engines (ChatGPT, Gemini) kill Google Shopping? No, not in any foreseeable timeframe. Direct purchase queries ("buy X at the best price") will remain predominantly on classic search for several more years. What's evolving is the discovery and comparison phase that's partially migrating to AI. The net impact is a reduction in top-funnel queries on Google Shopping, but not a disruption of transactional queries.
Does GMC compliance really affect campaign ROAS? Yes, in a documented way. Feed attribute completeness (titles, descriptions, color, size, GTIN) is used by Google in Shopping ad Quality Score calculation. Complete, consistent data improves ad relevance, reducing CPCs for the same placement. Impact ranges from 5% to 20% depending on starting level — it's the optimization lever with the best effort/result ratio.
Should you invest in GEO in addition to Google Shopping in 2026? GEO and Google Shopping use the same foundations — a quality GMC feed, complete Schema.org structured data, well-filled product pages. Investing in GMC compliance simultaneously improves Google Shopping performance AND GEO visibility. It's not a choice between the two — it's an investment that serves both channels.
The Essential Takeaway
Google Shopping remains profitable in 2026 — but not for everyone and not in the same way as before. The 2026 winners are merchants who:
- Specialize on queries where they have a real competitive advantage (not generic queries dominated by Amazon)
- Optimize their feed as a strategic asset (not just a CSV export)
- Maintain high GMC compliance for better Quality Scores
- Complement with AI engines via a GEO strategy built on the same foundations
GMC compliance is the starting point for each of these axes. A product page audit with MyGoogle gives you your current compliance score and priority fixes in 30 seconds.
