Your marketplace store might be half closed. You just don't know it.

How much revenue is trapped in your unpublished marketplace listings?

Key takeaways

• Check your publish rate before you optimize anything else. If products aren't actually live, more ad spend or better product pages won't help customers find or buy them.
• Product catalog problems usually build up over time. A few shortcuts, inconsistent updates, or changing marketplace requirements can slowly create gaps that are easy to miss.
• Don't assume a listing that works on Amazon will work everywhere. Every marketplace has different requirements, so products often need channel-specific data to publish successfully.
• Your biggest opportunity might not be your bestsellers. Smaller or overlooked products can become steady revenue drivers once they're actually visible to shoppers.
• A simple catalog audit can uncover revenue you didn't know you were missing. Reviewing your publish rate across every marketplace is one of the fastest ways to spot products that are in stock but never made it in front of customers.

You can spend months improving conversion rates, optimizing product pages, and investing in advertising. None of those efforts matter if customers can't actually buy the products you're trying to sell.

It's an easy problem to overlook because nothing appears to be wrong. Orders continue to come in, your bestsellers keep selling, and marketing campaigns keep running. Meanwhile, products that should be generating revenue remain invisible to shoppers.

Ryan Berg, founder of TALENTA Commerce, has spent years auditing catalogs for brands selling across Amazon, Walmart, Target Plus, and other marketplaces. "Publish rate is the first number I want, before anything else. Ad spend, campaigns, keyword strategy, all of that assumes the products you are trying to sell are actually visible to a shopper. If half your catalog is sitting unpublished, you are optimizing marketing dollars around a store that's half closed."

Ryan says publish rate quickly reveals how much of a seller's catalog is actually capable of generating revenue before he spends a single hour on strategy. “It's the cheapest, fastest audit I can run, and it almost always tells a story nobody in the room expected."

The products you forgot you were selling

You probably know exactly where your inventory lives. You can see what's in your warehouse, what's available in your ERP, and what's ready to ship. What isn't always obvious is whether every one of those products actually made it onto each marketplace where you intended to sell it.

Some products never complete that journey. They're stocked. They're sellable. They're simply unavailable to customers.

One way to think about these products is dark stock. Unlike dead stock, they aren't obsolete or difficult to sell. They never had the opportunity to sell because shoppers couldn't find them in the first place.

Ryan says sellers almost always underestimate how much of their catalog falls into this category. "Sellers know their bestsellers are live. Those are the products paying the bills, so of course they are watched closely. What they don’t see is the rest of the catalog sitting in the shadows – products with low visibility, incomplete data, or a status flag nobody noticed. I’ve walked into audits where getting the catalog dialed in with proper attribute data added 10% revenue growth without touching ad spend, without a single new SKU, and without a new marketing campaign. Just fixing what was already there."

Why these gaps are easy to miss

Catalogs rarely become incomplete overnight. They evolve over months or years as products are added, marketplaces expand, and different people update listings. Small inconsistencies accumulate until someone steps back and looks at the catalog as a whole.

Ryan says he can usually see that history immediately. "Every catalog tells me how many hands have touched it. You can see it in the data. Different naming conventions on similar products, attribute fields filled out inconsistently, bullet points that read like three different people wrote them in three different years. That’s because three different people probably did.”

The pattern he often sees is shortcuts. Someone needed to get a new item live fast, so they duplicated an existing listing and edited it to reflect the new product. 

“On paper that saves time. But in reality, details get left behind. The new product inherits attributes, categories, and search terms that belonged to the old one,” he says. “Nobody did this maliciously. Everybody was just trying to move fast. But speed without a process leaves scar tissue in the data, and that scar tissue is what I’m usually hired to clean up."

Marketplace requirements add another layer of complexity. Product data that satisfies Amazon doesn't automatically satisfy Walmart. Categories differ, required attributes change, and validation rules evolve, so listings that were healthy when they were created can become suppressed over time.

Those issues often remain hidden longer than sellers realize. "Years, in a lot of cases. And that is the part that stings, because the whole time it is invisible, sellers are still spending on ads and marketing campaigns to drive traffic to a storefront where a decent chunk of inventory can’t be found.” 

From the outside, the store looks open for business. Behind the scenes, entire shelves may be empty. “Nobody flags it because nothing is technically broken. It just takes someone pulling the full catalog against the full publish status to see what’s been sitting dark the whole time.” 

One of the biggest mistakes Ryan sees is assuming product data can move seamlessly from one marketplace to another. 

"The attribute requirements are different, the taxonomy is different, and required fields on one platform might not even exist on the other. When the import runs, the listing either gets rejected outright or goes live in a degraded, unsearchable state. It looks like it made it, but it actually never did.” 

Hidden revenue lives beyond your bestsellers

The products driving most of your revenue are probably the products receiving the most attention. They're monitored closely, updated frequently, and quick to raise alarms if something changes.

Ryan thinks about the opportunity through the lens of the 80/20 rule. Top performing products, the 20% doing 80% of the volume are live and selling. But it’s the other 80% of the catalog that never got the same attention.

“Most of those products don’t need to become bestsellers. They just need enough visibility to become solid, steady contributors instead of invisible line items. Taking underperformers from zero visibility to reasonable visibility is where I’ve consistently found the fastest and cheapest revenue lift in any account."

What one catalog audit uncovered

One audit still stands out for Ryan. While reviewing Scout's Target Plus catalog, he found that only 23 of 97 in-stock SKUs were actually listed on the marketplace. Nearly three-quarters of the catalog wasn't available for customers to buy.

"It was a significant amount of products that were invisible on one channel, while competitors with deeper catalogs were visible everywhere shoppers were looking."

It's an extreme example, but it shows how easily missing listings can go unnoticed. Businesses often assume that if products are live on one marketplace, they're live everywhere.

Is your marketplace store fully open?

If you're not sure, publish rate is a good place to start. Ryan relies on Zentail to monitor publish rate, identify unpublished listings, and give clients visibility into their catalog across every marketplace.

“The problem’s rarely the product. It’s rarely even the marketing. It’s the data sitting behind both of them, unnoticed for years, costing more than most people realize. Before you spend another dollar trying to get more eyes on your catalog, make sure the catalog you already have is actually on the shelf."
