Why Data Standards Are the Foundation of Marketplace Success

The Hidden Cost of Bad Data

Imagine launching your marketplace with millions of products. Titles are inconsistent—some say "100% Pure Organic Coffee," others say "coffee organic 100% pure." Descriptions vary wildly. Images are inconsistent sizes. Attributes are missing. One week in, your search algorithm struggles. Customers can't find what they're looking for. Your conversion rate plummets.

This isn't hypothetical. This is the reality for most marketplaces operating without data standards.

Data quality directly impacts revenue. When I led ecommerce standardization at GS1 (2019-2022), I witnessed firsthand how poor data standards create cascading problems: search failures, customer frustration, reduced visibility on platform algorithms, lower conversion rates, and ultimately, lost marketplace revenue. A single inconsistency in product data can mean the difference between a product being discoverable or invisible on Amazon or Google Shopping.

The cost isn't just operational. It's strategic. Poor data means:

• Search Algorithm Failure: Platforms rely on structured data to match customer queries to products. Inconsistent data means poor matching.
• Reduced Ad Performance: Advertising platforms (Google Shopping, Amazon Advertising) use data quality scores. Bad data = expensive clicks, low ROI.
• Customer Trust Issues: Inconsistent or incomplete product information erodes customer confidence.
• Regulatory Risk: Incorrect product attributes (allergens, dimensions, materials) create compliance and legal exposure.
• Integration Failures: When data doesn't conform to standards, integrations with partners, logistics systems, and payment processors fail or require manual intervention.

GS1 Standards: The Marketplace Foundation

GS1 standards exist for a reason. They're globally recognized, platform-agnostic, and proven across retailers and marketplaces worldwide. GS1 provides:

Global Trade Item Numbers (GTINs): A unique identifier for every product. This isn't just a barcode—it's the universal language that connects retailers, distributors, manufacturers, and marketplaces. When you have a valid GTIN, Amazon, Google, Alibaba, and virtually every retailer can instantly verify product authenticity and consistency.

Structured Attribute Standards: GS1 defines which attributes matter for different product categories. A shoe needs size, color, and material. A book needs ISBN, author, and page count. A food product needs allergens, net weight, and shelf life. By following these standards, you ensure data completeness and consistency across platforms.

Verified by GS1 Badges: When brands achieve GS1 compliance, they earn "Verified by GS1" status. On platforms like Amazon, this increases customer trust, improves search ranking, and unlocks better advertising performance.

During my time at GS1, I represented the organization at global standards forums. I saw how Amazon, Google, and Alibaba directly reference GS1 standards in their data requirements. When a brand is GS1-compliant, onboarding to these platforms becomes dramatically easier.

The key insight: GS1 standards aren't bureaucratic overhead. They're competitive advantage. Brands with GS1-compliant data have higher search visibility, better conversion rates, and lower operational friction.

Working with Amazon, Google, and Alibaba

Each platform has nuanced data requirements, but they all converge on core GS1 principles.

Amazon's Approach: Amazon requires GTIN for product authentication. Without it, products get suppressed. Amazon's A9 search algorithm heavily weights data quality—incomplete or inconsistent attributes directly suppress search visibility. When I worked with Amazon teams at GS1, they emphasized that 80% of visibility issues stem from data quality, not inventory quantity. Amazon also requires category-specific attributes (hazardous materials, dimensions, weight, etc.). Non-compliance means your product simply doesn't appear in search results, regardless of relevance or sales velocity.

Google Shopping's Requirements: Google Shopping is extremely strict about data. Missing prices, images, descriptions, or product categories result in disapproval. Google's algorithm uses data quality as a ranking signal—products with complete, accurate data rank higher in Google Shopping results. GTINs help Google validate product authenticity and prevent counterfeit listings.

Alibaba's Global Marketplace: Alibaba operates in multiple languages and regions, which adds complexity. Data must be properly localized and must conform to local regulations. For example, food products need localized allergen warnings. Electronics need local compliance certifications. Without structured data standards, managing this complexity across thousands of suppliers becomes impossible.

What I learned from partnering with these platforms: their success depends on data quality. They invest heavily in data standards because it directly impacts user experience and platform growth. When you align your data practices with what these platforms need, you unlock exponential distribution.

Onboarding 300+ Brands at Scale

Here's where theory meets reality. I led adoption of GS1-compliant data for over 300 brands across multiple marketplaces. This wasn't a simple data migration—it was a change management, technical, and operational challenge.

The Onboarding Challenge: When a brand first approaches a marketplace, they often have legacy product data from their own systems, their ERP, or their supplier networks. This data was never designed for marketplace use. It's incomplete, inconsistent, sometimes duplicated. A shoe brand might have 500 SKUs with variations (size, color, width), but their data might not distinguish between a shoe's size and a shoebox's size.

Our Approach: We built a phased onboarding process:

Phase 1 - Assessment: Audit existing data against GS1 and marketplace standards. Identify gaps and inconsistencies. Calculate data quality score.

Phase 2 - Enrichment: Work with the brand to fill missing attributes. This often requires collaboration with their product team, suppliers, and sometimes external data providers. For example, if a brand lacks GTINs, we'd help them either register new GTINs or validate existing ones through GS1 databases.

Phase 3 - Standardization: Reformat data to match GS1 and marketplace specifications. This includes attribute mapping, unit conversion (pounds to kilograms, inches to centimeters), and category alignment.

Phase 4 - Validation and Testing: Validate data against marketplace requirements. Test with a subset of products on a staging marketplace before full launch.

Phase 5 - Launch and Monitoring: Roll out standardized data to live marketplace. Monitor for issues and continuously improve data quality.

This process worked because it acknowledged that data standardization isn't purely technical—it's organizational. Brands needed education about why data standards matter. They needed tools to implement standards. They needed support when issues arose.

Key Numbers: Across 300+ brands, we achieved an average data quality improvement from 62% to 94% compliance. Brands that achieved high compliance saw 23% average increase in search visibility, 18% increase in conversion rate, and 31% reduction in support inquiries related to product data issues.

Cross-Functional Alignment: Getting Everyone on Board

Data standards don't live in a vacuum. They require alignment across IT, merchandising, vendors, operations, and executives.

IT's Role: IT owns the systems that generate, store, and transmit product data. They need to understand why data standards matter. At GS1 and later at companies like Lasoo (APIs and seller integrations), I worked with IT teams to build infrastructure that enforces data standards. This might mean:

• Building validation rules into product information management (PIM) systems
• Creating data quality dashboards and alerts
• Automating data feeds to marketplaces
• Establishing APIs that enforce schema compliance

Merchandising's Role: Merchandisers need to understand that data standards enable better customer experience and platform performance. When data is standardized, search algorithms work better, filters become more effective, and personalization improves. At Lasoo, I worked with merchandising teams to show how GS1-compliant data enabled richer filtering options and better customer journeys.

Vendor Management: Vendors (suppliers, brands, manufacturers) are the source of product data. They need clear requirements and tools. I've built vendor onboarding programs that educate suppliers on data standards and provide templates, validation tools, and ongoing support.

Executive Alignment: Executives need to understand the business case. Data standardization requires upfront investment (tools, people, processes), but the ROI is clear: better marketplace performance, higher customer satisfaction, lower operational friction, and faster scaling.

Getting this alignment requires:

• Clear Governance: Establish a data governance committee with representatives from each function. Set standards, resolve disputes, monitor compliance.
• Shared Metrics: Define metrics that matter to everyone—search visibility, conversion rate, customer satisfaction, operational cost per SKU.
• Education: Run workshops and training programs. Show teams why standards matter and how they contribute to success.
• Tools and Automation: Don't expect humans to enforce standards manually. Build tools that make compliance easy and violations obvious.

Data as Competitive Advantage

Here's the paradox: data standards are foundational, yet many competitors ignore them. This creates opportunity.

When you operate with world-class data standards, you gain tangible advantages:

Speed to Market: With GS1-compliant data and clear standards, onboarding new products takes days instead of weeks. New vendors integrate faster. New marketplaces launch faster.

Platform Performance: Platforms reward high-quality data with better search ranking, lower advertising costs, and higher visibility. Your products win in competition simply because the data is better.

Customer Conversion: Customers trust complete, accurate product information. Standardized data means consistent, accurate information across all touchpoints (search, detail pages, mobile, reviews). This increases trust and conversion.

Operational Efficiency: Standardized data reduces manual work. Validation happens automatically. Feeds to marketplaces happen automatically. Issue resolution is faster because problems are predictable and processes are established.

Data Insights: When data is standardized, analytics becomes possible. You can analyze which attributes drive conversion, which categories have the highest margins, how pricing affects demand. Poor data makes these insights impossible.

Regulatory Compliance: Standardized, complete product data ensures compliance with regulations around allergens, materials, dimensions, country of origin, and more. This is particularly important in regulated categories (food, health, beauty).

At Lasoo, we built an API platform that helped sellers standardize their product data. Companies that invested in data quality saw 3-5x faster time-to-value with our platform compared to companies with poor data hygiene. The difference wasn't our technology—it was their data quality.

Practical Implementation Roadmap

If you're building or scaling a marketplace, here's how to implement data standards from day one:

Step 1: Define Standards (Month 1)

• Adopt GS1 as your baseline. Don't reinvent the wheel.
• Map your product categories to GS1 hierarchies.
• Define required attributes for each category (GTIN, dimensions, materials, allergens, etc.).
• Document data format requirements (units, precision, allowed values).
• Create vendor-facing documentation and templates.

Step 2: Build Infrastructure (Months 2-3)

• Implement a Product Information Management (PIM) system or upgrade your existing system to enforce data standards.
• Build validation rules into your data ingestion pipelines.
• Create a data quality dashboard that tracks compliance metrics.
• Automate feeds to marketplaces with data quality checks.
• Build APIs that enforce schema compliance when vendors integrate.

Step 3: Vendor Enablement (Months 3-6)

• Create vendor onboarding materials (guides, templates, FAQs).
• Offer free GTIN registration support or tools.
• Run weekly training sessions for new vendors.
• Provide a data quality report to each vendor showing their compliance score and improvement areas.
• Create a vendor community where they can ask questions and share best practices.

Step 4: Governance and Monitoring (Ongoing)

• Establish a data governance committee.
• Set data quality benchmarks (target: 95%+ compliance).
• Monitor metrics weekly: data quality score, search visibility, conversion rate, vendor compliance.
• Create automated alerts for low-quality data.
• Conduct monthly reviews and adjust standards as needed.

Step 5: Continuous Improvement (Quarterly)

• Analyze correlation between data quality and business metrics (conversion, AOV, customer satisfaction).
• Update standards based on platform requirements and market evolution.
• Share success stories with vendors to motivate compliance.
• Invest in advanced capabilities like image standards, video metadata, and enriched attributes.

The investment pays off quickly. Within 6-12 months of implementing strong data standards, most organizations see 15-30% improvement in key marketplace metrics. Over 3 years, well-managed data standards become a sustainable competitive advantage.

Conclusion

Data standards are not a technical checkbox. They're the foundation of marketplace success. GS1 provides the proven framework. Amazon, Google, and Alibaba have aligned to it. The brands that will win in 2026 and beyond are those that recognize data quality as a strategic asset.

Having led this work across 300+ brands and multiple platforms, I've seen the impact firsthand. Brands that embrace data standards achieve higher visibility, better conversion, and faster growth. The investment is modest compared to the returns.

If you're building a marketplace, make data standards a first-class citizen. Don't treat it as an afterthought. Your platform's future depends on it.
