How do I manage and optimize large-scale product feeds with thousands of SKUs?

Learn how to manage and optimize large-scale product feeds for eCommerce—boost revenue, efficiency, and ad performance.

I’ve learned the hard way that scaling up a product feed from a few dozen SKUs to thousands, and sometimes millions, isn’t just a matter of copying product data across platforms. You can’t rely on luck and hope your ads perform well.

In my experience, managing large product catalogs is an ongoing cycle of improvement, automation and human insight. When you get it right, the rewards are incredible.

Today, I’m walking you through exactly how I handle large-scale product feeds. I share real stories, best practices and the technical steps to give you a clear path forward. No fluff, no bragging; just actionable advice that has worked for me and many businesses I have consulted with.

Keeping control of them without help from a feed optimization tool is almost impossible, so making you have a tool to lean is extremely important.

The High-Stakes World of Large-Scale Product Feeds

When you’re dealing with thousands of SKUs, the stakes are high. Every day you might find yourself updating pricing details, stock info, new color variations or shipping policies. Those routine tasks become massive undertakings at scale. But if you do it right, you can see dramatic gains in:

  • Revenue
  • Return on Ad Spend (ROAS)
  • Operational efficiency

I have seen auto parts retailers boost ROAS by 299%. I have watched custom apparel clients more than double revenue—229% growth—by revamping their feed structures.

I have worked with agencies that report an average of 184% higher ROAS across entire client portfolios. These numbers are not fantasies. They come from making product feeds work effectively.

The Core Challenges

Why is it so tough? Large-scale feeds naturally create complexity. Data might come from multiple sources (like ERP systems, PIM software or custom data sheets).

Each marketplace or advertising channel requires a specific format, attributes and structure. Multiply that across thousands of products and issues arise quickly.

I always break the challenge down into three areas:

  1. Quality of the product data.
  2. Consistency across channels.
  3. Automation without sacrificing accuracy.

If your feed has accurate, complete data and is properly formatted for each channel, you’re halfway there. With automation that maintains data integrity and brand identity, you gain a strong advantage.

Why PRODUCT FEED OPTIMIZATION Is So Critical

Optimization means ensuring search engines and marketplace algorithms understand your products well, while supplying potential buyers with the right information at the right stage of their purchase cycle.

It’s not about stuffing in keywords or just adjusting feed attributes. It is about:

  • Making sure your titles are clear, complete and easily searchable.
  • Writing descriptions that clearly state benefits and features in an authentic tone.
  • Providing accurate images, inventory counts and pricing.

When you get these pieces right, your product feed supports your e-commerce strategy by connecting your inventory with your ad campaigns effectively.

Real Examples of Impact

• A custom apparel company I worked with had over one million SKUs. Before optimization, their feed was missing key details like color variations, materials and specific long-tail keywords.

After a strategic overhaul—where we automatically generated variant-specific titles and included platform-specific attributes—they experienced a 229% revenue increase. That is the impact of proper feed optimization.

• An apparel and art retailer used dynamic text ads on more than one million products. By fine-tuning product titles and adding targeted seasonal descriptors, they reported a 125% increase in ROAS. Small changes produced significant results.

Key Impacts of Optimizing Large-Scale Product Feeds

A well-structured and maintained feed brings specific benefits:

  1. Multiplying an improved click-through rate by thousands of listings yields a large overall impact.
    • Auto parts retailer: +299% ROAS.
    • Custom apparel client: +229% revenue.
    • Apparel and art company: +125% ROAS.
    • Major flower retailer: 3.7x increase in online product sales.
  2. This approach helps shoppers find you through both search and paid channels, reducing wasted clicks on unavailable items.
    • Using titles and descriptions with relevant keywords.
    • Providing complete attribute data (material, color, size, etc.).
    • Automating pricing and stock updates whenever inventory levels change.
  3. With solid software support (such as Feedonomics or DataFeedWatch), you not only reduce manual work but build systems to handle seasonal spikes and growth.
    • Bulk editing that processes thousands of products in minutes.
    • Scheduled feed updates for daily or hourly inventory changes.
    • Direct integrations with marketplaces like Amazon, Google Shopping and Facebook.

My Go-To Best Practices

I have refined my methods over many projects. Here is my playbook:

1. Conduct a Thorough Feed Audit

Before making any enhancements:

  • Look for incomplete data (missing attributes, empty sections, outdated pricing).
  • Consolidate information across sources to create one reliable data set.
  • Identify channel-specific errors flagged in Merchant Center or Amazon Seller Central.

A complete audit shows what needs fixing, what is missing and which products perform poorly.

2. Standardize and Clean up Product Data

Your raw input should be as clean and uniform as possible:

  • Use universal attribute headers that fit every channel.
  • Adopt a consistent naming system for colors and sizes.
  • Ensure consistent pricing formats (currency codes, decimal places etc.).

Keeping data consistent means fewer issues later.

3. Automate with Care

Automation increases scale, but poor handling can cause errors. I use feed management platforms that let me:

  • Apply bulk transformations (for example, adding brand names to product titles).
  • Map store categories automatically to match Google’s category taxonomy.
  • Insert shipping or stock info dynamically.

A human should always check the feed for tone and proper categorization. Automation is helpful, but it is not flawless.

4. Optimize Titles and Descriptions for Discovery

The product title is a key SEO factor across channels:

  • Place important keywords at the start.
  • Include details like brand, model and variant if needed.
  • Keep it clear: avoid excessive keyword repetition or unrelated info.

For descriptions, emphasize key benefits that matter to buyers. This detail can set you apart in search results.

5. Use Custom Labels

With thousands of SKUs, it is impossible to adjust bids individually. Custom labels group items for easier campaign management. For example:

  • High-margin products might get a “high_margin” label.
  • Seasonal products can be tagged “seasonal_promotion.”
  • Overstock items can receive a “clearance” label.

This lets you adjust bids or promotions across groups quickly.

6. Monitor and Improve with Analytics

No feed is ever truly finished. Once it is live, you should:

  1. Review performance data (clicks, conversions, ROAS).
  2. Identify which products perform well and which do not and adjust accordingly.
  3. Try new keywords, images or promotional text to keep improving results.

A regular optimization cycle, whether weekly or monthly, is vital to remain competitive.

Stories from the Field

I worked with an online marketplace specializing in artisan goods, whose initial feed was a mix of missing product details and mislabeled categories. Poor search visibility was limiting sales.

We started with a two-step process. First, we standardized the data throughout the catalog by pulling information from multiple warehouses and order forms.

Then, we set up automation to keep the feed current across platforms like Google Shopping, Etsy and Amazon. Within three months, daily sales increased by 48%, and the brand reached new audiences.

In another case, a direct-to-consumer clothing brand with tens of thousands of SKUs struggled with high shipping fees caused by incorrect size and weight labels. They automated the shipping attribute updates linked to their inventory system. As a result, returns dropped and shipping cost discrepancies nearly disappeared.

Common Pitfalls and How to Avoid Them

Even experienced teams can make mistakes. Here are some common issues and ways to avoid them:

  1. Overlooking Channel Requirements
    • Each platform has its own specific attribute formats.
    • Always review the official specifications for Google Merchant Center, Amazon and others.
  2. Neglecting Image Quality
    • Low-resolution or improperly sized images hurt conversions.
    • Use automation to ensure images meet required dimensions and resolution.
  3. Skipping Ongoing Maintenance
    • A “set it and forget it” approach leads to outdated or inaccurate listings.
    • Organize regular feed reviews and updates.
  4. Ignoring Analytics
    • Without data, identifying underperforming products is guesswork.
    • Track performance metrics closely and make timely adjustments.

The Role of Automation Tools

Automation tools are essential for scaling. They act as a link between your product catalog and each channel. Some benefits include:

  • Centralized data management: Update one feed to push changes everywhere.
  • Real-time synchronization: Keep pricing and inventory accurate.
  • Advanced feed transformations: Make attribute edits without manual work.

I recommend solutions like Feedonomics or DataFeedWatch when you work with large product sets. These systems simplify managing listings on multiple channels. If your platform supports native integrations or apps for feed management, give them a try.

Balancing Automation + Human Insight

People often ask if everything can be automated. My answer is that I automate most feed tasks—like inventory sync, attribute mapping and daily updates—while devoting extra effort to strategic oversight.

  • Check high-impact categories carefully.
  • Occasionally update product titles and descriptions for seasonal campaigns.
  • Monitor performance metrics for any irregularities.

This mix of automated processes and human review keeps the feed effective and aligned with brand standards.

Scaling Up with Confidence

The switch from a few dozen to thousands of SKUs can seem overwhelming. Manual methods that worked with smaller catalogs will not scale. Instead, plan for growth by:

  1. Using a strong feed management solution designed for expansion.
  2. Enforcing data consistency so that everyone enters product information in the same way.
  3. Simplifying the review process by having key team members perform final checks.

With the right systems in place, some teams have quadrupled their SKU count in a year without major issues.
