The Merchandising Machine: complete control over your online shelf

By Paul van Renselaar, Head of Sales & Customer Success at Tweakwise
The Merchandising Machine shows how you keep control of your online shelf when assortments grow, campaigns change faster and visitors expect more relevance.
In this blog, you will read how these layers work together and why that matters. You will discover how to become less dependent on separate manual actions and steer product visibility in a smarter way. This gives you more room for brands, campaigns and new products, without losing control over the product experience.
In many webshops, merchandising starts with the question of which products should appear at the top. Which products deserve more visibility? Which products should temporarily receive less attention? Which campaign should be highlighted? And where should you place a banner, product tile or visual element?
These are important choices. But they also show that merchandising is much more than sorting products.
Modern merchandising is about control over the full product experience. You decide which products visitors see, why they see those products, how they move through the assortment and how commercial choices become visible in the online shop.
That is why Tweakwise looks at merchandising as a machine. Not as one separate feature, but as a connected system of choices. A system in which strategy, commercial steering, manual control, visual structure and personalization reinforce each other.
That is exactly what The Merchandising Machine is about: a merchandising approach built around four layers. From your strategic foundation and commercial steering to manual control and the visual structure of your product list. Together, these layers make sure you do not only decide which products are visible, but also how your online shelf is commercially arranged.

Watch Paul van Renselaar explain The Merchandising Machine

In this video, Paul explains how The Merchandising Machine helps e-commerce teams gain more control over their online shelf. From the default product order to commercial steering, visual merchandising and personalization.
Layer 1: Default Merchandising

Merchandising starts with a clear foundation

Every strong merchandising approach starts with a foundation. Before you start boosting, pinning or personalizing, it needs to be clear what is structurally important for your business.
Think of margin, stock, popularity, conversion and business rules. These are the commercial signals that determine how your assortment is ranked by default.
That foundation ensures products do not appear randomly in a list. The default order matches what is commercially important and what helps visitors find relevant products.
Tweakwise The Merchandising Machine Layer 1: Default Merchandising
You can compare this to a physical store. The layout is not random there either. Products are placed logically based on sales, availability and commercial value. Popular products get a logical position. Products with enough stock are clearly visible. And categories are arranged so customers can easily find what they are looking for.
Online, it works the same way. The scale is simply larger, the context changes faster and there are many more signals that influence the order.
That is why Default Merchandising forms the first layer of The Merchandising Machine. It is the foundation on which everything else is built.
Layer 2: Commercial Merchandising

Commercial steering without changing your foundation

Once the foundation is in place, you want to be able to make adjustments as an e-commerce team. Without constantly changing the full structure, you add commercial choices on top of that foundation.
This is where Commercial Merchandising comes in.
With our Boost & Bury module, you adjust the ranking based on commercial priorities. This can be temporary, for example during a sale, seasonal campaign or product launch. But it can also be structural, for example when you want certain brands to appear more prominently within a category, or when you deliberately want to give specific search terms a different commercial direction.
Think of boosting a new collection. Giving campaign products extra visibility. Burying products that are temporarily less relevant. Or strengthening a brand strategy within a specific category.

The important difference is that you do not have to replace the foundation. You adjust the ranking where needed, without having to rebuild the full default logic.
The comparison with offline retail also helps here. A store has a fixed base layout, with promotions, seasonal displays and deliberate commercial choices layered on top. A brand can structurally receive more space. A promotional product can temporarily get a better position. A new collection can receive extra attention.
Commercial Merchandising does the same online. It gives e-commerce teams room to steer flexibly, while the underlying merchandising strategy remains in place.
Layer 3: Manual Merchandising

Sometimes you want to intervene manually

You do not want to make every merchandising choice manually. In fact, you want to prevent that as much as possible.
The strength of modern merchandising lies in a strong foundation, smart commercial steering and rules that work at scale. If you have to manually decide where every product should appear, merchandising quickly becomes time-consuming, error-prone and difficult to manage.
Still, there are moments when you want to very deliberately deviate from the automatic logic.
For example, because a specific campaign product temporarily needs to be absolutely visible. Because a product is commercially important on a specific page. Or because, in an exceptional situation, you want to decide exactly which product appears in a specific position.
Manual Merchandising is there for those situations.
With Product Push, you can intervene in a targeted way on specific pages. You decide which products are explicitly brought forward and give them extra visibility within the available space.
This layer is mainly intended as an extra control layer for situations in which you very deliberately want to deviate from the foundation and commercial steering.
The same happens in a physical store. The store layout and promotions normally determine where products are placed. Only when there is a clear reason, a store manager manually places a product in a prominent position.
Manual Merchandising gives you that same possibility online: as a targeted exception when it is truly needed, rather than as the starting point.
Layer 4: Visual Merchandising

Temporarily give extra attention to a new collection

Merchandising is not only about the order of products. It is also about the space you deliberately reserve in the product list for commercial choices.
That is why Visual Merchandising is the fourth layer of The Merchandising Machine.
With the Merchandising Builder, you decide which information, products or visual elements appear in specific positions in the product list. Think of a fixed position for your own brand, extra space for sale products, attention for a new collection or a dynamic tile that responds to the context of the page.
This gives you more influence over the layout of your online shelf, without losing the dynamics of the product list. The listing continues to move with relevance, stock, commercial rules and personalization, but within a structure that you have deliberately set up.
This turns the product list into more than an automatic sequence of products. It becomes a commercial shelf where you can create space for brands, campaigns, new products and other priorities that matter at that moment.

That makes the structure logical and controllable. You prevent separate merchandising actions from getting in each other’s way and make sure the product list as a whole continues to work.
You can also compare this to a physical store. Visual Merchandising is the layout of the shelf and the store floor. Where do you place displays? Where do you place visuals? Where do you give a brand extra space? Where do you want customers to stop, look or click through?
Online, you want that same level of control. Not only over the order of products, but over the full way in which the assortment is presented.
Next step: Personal Merchandising

Personalization as the next step

Personal Merchandising is not a separate fifth merchandising layer. It is the next step in maturity.
First, the foundation needs to be right. Your merchandising strategy needs to be clear. Your commercial steering needs to work. Manual control needs to be available when needed. And the structure of your product list needs to be solid.
Only then does personalization become truly powerful.
Personal Merchandising makes the existing merchandising setup smarter and more relevant for each visitor. It does not change your full setup, but makes it more dynamic and personal.
Within Boost & Bury, for example, you can work with personal boosts. Within the Merchandising Builder, you can show blocks that match behavior, such as recently viewed products or other personal recommendations.
The store remains the same store. The base layout stays in place. The commercial choices remain intact. But the experience adapts better to the individual visitor.
Offline, you could compare this to a salesperson who knows the store well and shows you slightly different products based on your preferences. The store is not rebuilt for every customer, but the guidance and product selection become more relevant.
That is exactly the role of Personal Merchandising within The Merchandising Machine. It makes the machine more intelligent, without replacing the foundation.

How the layers work together

The strength of The Merchandising Machine is not in one separate layer, but in the way all layers work together.
The foundation determines the default order of products. Commercial Merchandising adjusts that order dynamically or structurally based on commercial choices. Manual Merchandising gives extra control when specific products need to be deliberately brought forward. Visual Merchandising determines how the product list is visually and structurally built. And Personal Merchandising makes the whole experience more relevant for each visitor.

This creates a system in which merchandising no longer consists of separate actions, but of connected steering.
That matters because visitors do not experience these elements separately either. They do not see a separate strategy, boost rule, product push or builder position. They see one product experience. One search result. One category page. One shopping journey.
That is why all merchandising choices need to work together.

From manual adjustments to smart steering

Many e-commerce teams already have a strong foundation. They know which products are relevant, which commercial signals matter and which campaigns need attention.
But as assortments grow, campaigns change faster and visitors expect more relevance, manual adjustments become less and less scalable.
The Merchandising Machine helps you make that shift. From separate merchandising actions to a system in which you connect commercial strategy, ranking, manual choices, visual structure and personalization.
By organizing control better, rather than letting it go.
Modern merchandising is not about pushing as many products as possible to the top. It is about making deliberate choices. Which products deserve visibility? When? For whom? And within which commercial context?
With The Merchandising Machine, Tweakwise helps e-commerce teams make those choices in a smarter, more consistent and more scalable way.
That is how you move from product order to commercial control.
