Why Your Products Aren’t Selling Even Though They’re Excellent?

You’ve invested months – sometimes years – in launching a solid product, validated by your customers in stores. It is liked, it meets a need, it works. But online, on Amazon or other marketplaces especially, the results are slow to come. Frustrating? Absolutely. Unusual? Not at all. It’s a challenge that even the best products face without the right digital strategy.

At Sellingz, we see this scenario every day. And here’s the good news: in 90% of cases, the problem isn’t the product but its presentation. Or rather: its performance in the coded, rigidly programmed, algorithmic universe of marketplaces.

Here are the five major reasons why your products may remain invisible… despite their excellence.

Why your products aren’t selling

1- Your Catalogue is “Beautiful” but Not SEO-Friendly

A good product is good. A good listing is better. On Amazon, visibility is primarily dictated by the A9 algorithm. It scans titles, bullet points, descriptions… and expects a specific format, designed for search engines:

Titles: optimal length, strategically placed primary keywords.
Descriptions & bullet points: customer benefit-oriented, but semantically optimized.
Back-end keywords: often forgotten but crucial.

The result: a poorly structured or “referenced” product will literally be invisible in search results. Even if it’s great.

2- Your Visuals Don’t Entice (Especially on Mobile)

Today, over 70% of purchases are made from smartphones. If your visuals aren’t designed mobile-first, you’re losing sales.

Here’s what Sellingz recommends:

High-quality studio images, captured from various angles and in real-life situations.
Integrated infographics: explaining benefits in a single image.
Local language mandatory in visuals (FR for France, DE for Germany…).
Product video: whether branded, product-specific, or created from images, it reassures and significantly increases conversion.-

A listing without visual storytelling is like a poorly lit storefront. The product misses its audience.

3- Your Price… Works Against You

Price isn’t just a marketing positioning question. It serves as a purchase trigger and a major criterion for the algorithm.

Two common mistakes:

Being more expensive than direct competitors without perceived justification.
Being more expensive than other sellers of the same product: you lose the Buy Box, i.e., the “Add to Cart” button…

On Amazon, this button is vital: over 95% of sales go through the Buy Box. So, it’s not enough to be present: you need to be purchasable.

4- You Lack (Enough) Reviews

On Amazon, and on most marketplaces, product reviews are both an algorithmic ranking criterion and a trust trigger.

The basics:

Aim for a minimum of 30 reviews per product (SKU or ASIN in Amazon’s case).
Maintain an average rating above 4 stars.

Buyers don’t always read reviews, but they immediately look at the overall rating and review volume. And so does the algorithm.

For new products, Sellingz recommends quickly activating the Vine program or other seeding devices. It’s also important to budget for advertising on Amazon: despite all initial activation levers (Vine reviews, optimized SEO, polished product page), without advertising, a launch may not take off. Advertising then becomes an essential complement to the Vine program for generating initial sales.

5- (As a Seller) You’re Penalized by Your Logistics or Seller Rating

Even if everything is perfect on the product and content side, Amazon will always favour the best customer experience.

This includes:

Well-rated sellers (seller account > 4 stars)
Reliable and fast logistics
Best models for performance:
- Vendor (direct sales to Amazon).
- Seller FBA (fulfillment by Amazon).
- Ultra-responsive FBM, with express delivery + excellent reputation.

Note: Amazon may give the Buy Box to a more expensive seller if they deliver faster. In the last mile battle, the promise trumps price.

Why your products aren’t selling

In Conclusion

Your product may be excellent, but it’s not what the algorithm evaluates. It’s its listing, visuals, reviews, price, logistics.

The good news? All these elements can be optimized. And that’s exactly where Sellingz comes in: by building a marketplace strategy for your catalogue, then optimizing processes with data, and bringing method and operational intelligence to your ambitions.

Putting a product online or launching an advertising campaign is simple and similar to what you were already doing with traditional retailers. But turning this presence into real and profitable sales on marketplaces, while mastering your entire value chain, is much more complex. This is precisely where Sellingz steps in: to help you navigate this complexity, structure your actions, and make the most of every available lever.
