Here's what nobody tells you about Google Shopping campaigns: while everyone's obsessing over bidding strategies and budget allocation, they're missing the real culprit behind poor performance.

After analyzing hundreds of campaigns and the latest 2025 data, I've discovered that 85.3% of all Google Ads clicks come from Shopping campaigns, yet most advertisers are leaving money on the table because of one fundamental oversight.

It's easy to blame poor performance on obvious things like bad headlines or weak creatives, but in many cases, the real problem is hidden deeper in the setup.

If you're working with a platform like Google Shopping, and still not seeing return on ad spend, it could be time to speak with a google shopping agency that understands the back-end issues that don't show up in your ad preview — but wreck results all the same.

The numbers tell a stark story. According to Store Growers' 2025 research, the average Google Shopping conversion rate sits at just 1.91%, with some industries struggling at 0.83%.

Meanwhile, successful campaigns are achieving 400% ROAS or higher. What separates the winners from the losers? It's not what you'd expect.

Google Shopping Performance Stats 2025 85.3% of all Google Ads clicks come from Shopping campaigns 1.91% Average CVR Shopping Campaigns $770.41 Average Monthly Ad Spend ROAS Performance Gap Poor Campaigns: 0.84 ROAS Average: 1.91 ROAS Optimized: 4.0+ ROAS The Hidden Problem: Most advertisers focus on bidding strategies while ignoring product feed optimization — the real foundation of success

Your product feed is sabotaging your success

According to Dr. Dennis Moons, Google Ads Specialist at StoreMaven, "The most popular products will always be part of the first few ads. And its algorithm keeps track of the clickthrough rates on those offers.

Google does this to make sure that the products that it does show, will get clicks" (LinkedIn).

Think about that for a second. Google's algorithm is actively working against poorly optimized feeds. It's like trying to win a race with flat tires - you can have the best driver (bidding strategy) and the most fuel (budget), but you're still going nowhere fast.

The data backs this up dramatically. A case study from DataFeedWatch showed a B2B industrial client achieving a 451% ROAS increase simply by switching from Content API to a properly managed feed.

They didn't increase their budget. They didn't revolutionize their bidding. They just fixed their foundation.

The $770 monthly mistake most businesses make

WordStream's 2025 research reveals that the average advertiser spends $770.41 per month on Google Shopping. But here's the kicker - most of that money is wasted on campaigns built on shaky foundations. The US Census Bureau reports e-commerce hit $275.8 billion in Q1 2025, growing 6.1%, yet individual advertisers aren't seeing proportional returns.

According to Brett McHale, Founder at Empiric Marketing, "Everything comes down to your landing page offer in combination with your ad. If your focus area was on making your ad and landing page as conversion-friendly as possible, then CVR will improve as well" (WordStream).

But even perfect landing pages can't save a campaign with feed problems. Tessar Napitupulu, CEO of Arfadia and Digital Marketing Expert with over 20 years of experience, explains: "In my two decades managing digital campaigns across Southeast Asia, I've seen businesses pour millions into sophisticated bidding algorithms while their product feeds remain fundamentally broken. It's like building a Ferrari engine and putting it in a car with square wheels - the foundation determines everything" (Arfadia).

Industry benchmarks from multiple sources show that properly optimized feeds achieve:

  • 20% higher click-through rates
  • Lower cost-per-clicks
  • 95%+ product approval rates

Compare that to the average campaign struggling with disapprovals, limited visibility, and wasted spend.

Performance Max isn't your silver bullet

Here's something that might surprise you: Performance Max campaigns, which peaked at 82% cost share in May 2024, are actually declining by 0.65% monthly according to Smarter Ecommerce data. Advertisers are rediscovering Standard Shopping campaigns because they offer more control.

Performance Max vs Standard Shopping Performance Max Campaigns ✓ Pros: • AI-driven optimization across all Google properties • Access to YouTube, Gmail, Discover placements • Automated asset testing and optimization ✗ Cons: • Requires 30+ monthly conversions minimum Standard Shopping Campaigns ✓ Pros: • Full control over bidding and targeting • Detailed performance insights • Works with any conversion volume • Better for small budgets and testing ✗ Cons: • Limited to Google Shopping placements only Expert Recommendation: Start with Standard Shopping campaigns to build foundation and reach 30+ conversions, then graduate to Performance Max PMax usage declining 0.65% monthly

According to Dr. Dennis Moons, Performance Marketing Specialist, "Performance Max struggles on a small budget / low amount of conversions. 30 monthly conversions really is the minimum threshold. Campaigns with a conversion volume of 150+ are able to hit their target ROAS much more consistently" (LinkedIn).

This creates a catch-22 for smaller businesses. They need conversions to make Performance Max work, but they can't get conversions without proper optimization. The solution? Start with the basics.

The three-step fix that actually works

Looking at successful case studies, a clear pattern emerges. Jyll Saskin Gales transformed a skincare client's campaign from 0.84 to 2.69 ROAS in just four months. Her approach was deceptively simple:

Step 1: Ruthless product segmentation

Export your product-level performance data and categorize items as:

  • Heroes: Your best performers (keep and optimize)
  • Kitties: Medium potential products (test and improve)
  • Doggies: Poor performers (eliminate immediately)

One cosmetics retailer using this approach saw their ROAS jump from 1.0 to 10.0 in just six weeks (AdWords Robot). They didn't add products - they removed the dead weight.

Product Feed Optimization The Foundation of Success 1 Product Segmentation • Heroes: Top performers (optimize) • Kitties: Medium potential (test) • Doggies: Poor performers (eliminate) +400% ROAS 2 Feed Quality Optimization • Front-loaded titles (70 chars) • High-quality images (1600x1600px) • Complete GTIN attributes • Regular updates (daily/weekly) +20% CTR 3 Strategic Campaign Structure • Priority-based campaigns • Product group segmentation • Negative keyword filtering • Enhanced conversion tracking Smart bidding Expected Results: 451% ROAS increase • 95%+ approval rates Lower CPC • Higher visibility

Step 2: Feed optimization that Google loves

Current 2025 best practices demand (Google Support):

  • Front-loaded titles: Brand + Model + Key Features within first 70 characters
  • High-quality images: Minimum 800x800 pixels, but 1600x1600 performs better
  • Complete attributes: Including GTIN increases approval rates by 20%
  • Regular updates: Daily or weekly to prevent the 30-day expiration

IAB's 2025 report shows US digital ad revenue hit $258.6 billion in 2024, up 14.9% year-over-year. Google Shopping claimed 76.4% of all retail search ad spend. Yet most advertisers can't access this opportunity because their feeds don't meet basic requirements.

Step 3: Strategic campaign structure

According to Cliff Sizemore, Digital Marketing Strategist at LocaliQ, "Costs are rising, but so is performance—65% of industries saw better conversion rates in 2025. The main takeaway here is that a smart strategy beats cheap clicks" (WordStream).

The winning structure includes:

  • Priority-based campaigns: High, medium, and low priority with strategic negative keywords
  • Product group segmentation: By brand, profit margin, or performance metrics
  • Proper attribution: GA4 and enhanced conversions for accurate tracking

You're Not Tracking What Matters

Even if everything looks right on the surface, you won't know what's actually working unless you're tracking conversions properly.

Double-check:

  • Are your conversion actions set up in Google Ads (not just in Analytics)?
  • Are you tracking revenue, not just purchases?
  • Do you have visibility into device, location, and time-of-day performance?

Small insights — like learning that most of your conversions happen on mobile after 8pm — can change how you budget and bid.

You're Not Testing (Or You're Testing Too Much)

Split testing is important, but only when it's done with purpose. If you're constantly changing copy, bids, and structure all at once, you'll never know what made the difference.

Start with one variable:

  • Try different product titles for your top five items
  • Adjust bid strategies on one campaign
  • Test a new product image for your best seller

Let the data tell the story — then build from there.

Why Indonesian businesses have a unique advantage

For Indonesian digital marketers targeting local and international markets, there's actually good news.

While global average CPC for Google Shopping is $0.66 (Store Growers), strategic market entry often means less competition for well-optimized campaigns. The key is meeting international standards for feed quality while leveraging local market knowledge.

A furniture retailer following this approach achieved 6.08 ROAS - well above the 4.0 benchmark. They didn't compete on price; they competed on relevance and quality.

The future is already here (and it's visual)

Google Lens now processes 20 billion visual searches monthly, with 20% being shopping-related (Google). Circle to Search has 33% weekly usage among users. According to Katia Hausman, Performance Marketing Director at LocaliQ, "As Google Ads CPCs and cost per lead continue to rise, we actually see the reverse in Microsoft Ads. It's an interesting trend that can help to offset growing costs" (WordStream).

But here's the thing - none of these opportunities matter if your foundation is broken. You can't benefit from visual search if your products aren't even showing up in regular search.

The bottom line that matters

Alessandro Colarossi, Senior Digital Marketing Manager at SearchKings, cuts through the noise: "Cost per lead is an essential metric, but measuring lead quality and value is just as important today. Advertisers need to track the real business impact of those leads" (WordStream).

Based on comprehensive 2025 data and proven case studies, here's what actually moves the needle:

  1. Fix your feed first - This alone can increase ROAS by 200-400%
  2. Segment ruthlessly - Focus 80% of budget on your top 20% of products
  3. Track everything - Proper conversion tracking is non-negotiable
  4. Start with Standard Shopping - Get to 30+ monthly conversions before Performance Max
  5. Optimize for mobile - 42% of Google Shopping revenue comes from mobile devices (Store Growers)

The hidden reason your ads aren't making money isn't complicated algorithms or secret bidding strategies. It's the unsexy, fundamental work of feed optimization and proper campaign structure.

Fix these basics, and you'll outperform 90% of your competition who are still chasing the latest shiny tactics while ignoring their foundation.
