Reasons Why Your Amazon Inventory Is Not Selling | Amazon FBA Buy Box

There are many factors to consider when trying to obtain consistent sales online, including buy box optimization and Amazon mobile optimization.

Amazon inventory sometimes becomes stagnant, leaving Amazon sellers with low to no sales at all. Many Amazon sellers experience Amazon inventory that just does not sell. Instead, such products end up sitting in the Amazon warehouse, incurring storage fees.

The reason behind stale Amazon inventory can vary from one seller to another and there are many factors to consider when it comes to selling on Amazon. Some of these factors can be categorized into pricing, Amazon FBA Buy Box, Amazon listing optimization, and customer service-related issues. 

Improving Amazon FBA Buy Box Win Rate Through Proper Optimizations

To give you an overview of what might be causing such slow-moving Amazon inventory, here are some of the top reasons Amazon sellers should be wary about. 


One of the reasons why an Amazon store or Amazon inventory is not selling is lack of access to the Amazon Buy Box. and proper buy box optimization. Some reasons why sellers are not awarded the Amazon Buy Box are highlighted below. 

1. Off-Site & On-Site Product Price Discrepancy 

When it comes to product pricing, Amazon has an advanced algorithm to check for the average product price online. The Amazon algorithm can easily check whether an Amazon listing item is priced too high or too low for its particular category.

Amazon technology goes beyond its own platform, its servers can also scrape data from other online selling platforms. This allows the algorithm to suppress the Amazon FBA Buy Box for Amazon inventory with a big pricing discrepancy.  

Experienced Amazon sellers make use of automated Amazon repricers to help them combat this and ensure that their Amazon inventory prices fit the current marketplace situation and adjust accordingly to competitor’s pricing behavior. This aids in optimum buy box optimization. 

2. Amazon Buy Box Glitch

There have been reported instances where Amazon sellers are not being awarded the Amazon Buy Box, despite being the cheapest or most competitive item. 

That is why sellers who are still having issues with a particular Amazon inventory should check for possible system glitches. The so-called Amazon Buy Box glitch is not the first time Amazon has encountered some error. 

In the past years, there have been a number of system errors observed by Amazon sellers, and some of these system issues were even acknowledged by Amazon. 


Besides the pricing and Amazon Buy Box oversight, an optimization mistake, including Amazon mobile optimization, is among the factors that influence poor Amazon inventory movement. Slow product movement may be caused by various optimization mistakes.

3. Listing Non-Amazon Sanctioned Categories

When it comes to listing optimization, sellers must be aware of the qualifications and approval requirements of certain Amazon inventory. In particular, sellers are required to get approval from Amazon before they can list a product to a specific category. 

If you are planning to list a certain brand, as part of the optimization process, you should first identify whether the inventory item requires approval or not. To know which products and categories require approval from Amazon, you may CLICK HERE

4. Product Title Guideline Violations

Another commonly violated rule by some Amazon sellers would be the product title guideline. When listing Amazon inventory, it is recommended to optimize the title of the listing. However, some sellers end up overly optimizing the title section of the listing.

When it comes to adding titles to your product listing, Amazon is very stringent with the rules. Amazon sellers should follow guidelines and avoid adding identifying details about the item in the title. To avoid this mistake, here are some title guidelines coming directly from Amazon Seller Central. 

  • Title containing promotional keywords and phrases (for example, free shipping, 100% quality guaranteed, etc.)
  • Title containing non-readable characters including emojis.
  • Title exceeding more than 200 characters.
  • Title not containing any product identifying information (no product type name and no product characteristics – for example, a single word title such as N/A)

5. Your Amazon Listing is Not Optimized Enough 

Another optimization mistake that hinders inventory movement is inadequate listing optimization. Optimizing the product title is not enough when it comes to scaling up your Amazon store. 

Other aspects of product listing should be optimized as well. As well as the title, sellers should optimize images, key features, product descriptions, and as mentioned before, pricing.


Customer service is another key factor for sales when it comes to Amazon. For sellers experiencing issues with their Amazon inventory movement, be sure to check customer service performance and other related aspects of customer service. To serve as a guide, here are some of the factors affecting product movement in relation to customer service:

6. Not Having Enough Good Reviews

Research shows that 84% of online shoppers trust online reviews. Whether it is on Amazon or other online platforms, good reviews really matter. In order for Amazon sellers to improve their chances of selling Amazon products, having good reviews is a must. 

Similarly, 22% of online shoppers would stick to Amazon if they could find products suitable for their needs and wants. And one of the criteria of a reliable and trustworthy Amazon product is the good reviews associated with it. 

7. Response Tone 

Another component that is influential to Amazon inventory movement is the review response and its tonality. Getting upset with customers is always a NO-NO when it comes to the Amazon business. 

It cannot be helped that some customers complain, demand, argue. Arguing leads to negative feedback, which can have a really negative impact on your business.

Misunderstanding How Amazon Works

Perhaps one of the most prevalent and yet less commonly acknowledged factors for slow Amazon inventory movement is the lack of proper knowledge on how Amazon really works. Some Amazon sellers who have experienced selling on other platforms are guilty of misunderstanding the Amazon interplay upon their first try with Amazon Seller Central.

To avoid committing mistakes when it comes to setting up and running it, you should do prior research. Understanding the guidelines set by Amazon will also help increase your Amazon inventory movement.
