Product categorization
A product in the wrong category is a product nobody finds.
Cernel sorts every product into its category as it arrives, by the instructions you write for each one, so it gets the fields and filters shoppers use.

How it works
From a supplier row to the right shelf, in five steps.
What happens to every new product from the moment it arrives, without anyone sorting it by hand.
It arrives
A new product comes in, often with little more than a code, a short title and a few columns from the supplier.
It is read
Cernel reads its title, brand, description, product data and images, the way someone on your team would.
It is sorted
At each level of the tree it picks the subcategory that fits best, down to the most specific one, following the instructions written for each category.
It gets its fields
The category brings the fields that kind of product needs, and the agents that fill them.
It goes back
You choose what goes live automatically and what gets a review step. Filled values go back to your PIM or shop, or out as a file in your own columns.
Your own taxonomies
Every category follows its own instructions.
Describe each of your categories in plain words: what belongs in it and what does not. Try it on a few of your products, read why each one landed where it did, and only then sort the catalogue.

What belongs in Ceiling lamps
Lamps that hang from or are fixed to the ceiling: pendants, chandeliers and flush mounts. Lamps that stand on a table or the floor, and lamps fixed to a wall, go elsewhere.

FAQ
Questions about product categorization.
What is ecommerce product categorization?
It is placing every product in the category where it belongs, in a tree that runs from broad to specific, so it gets the right fields, filters and channel categories. Cernel does it automatically: as products come in, each one is sorted into its category.
How does Cernel decide which category a product belongs in?
It reads the product's title, brand, description, data and images, and works down the tree, choosing the subcategory that fits at each level until it reaches the most specific category. When a product has too little to go on, it is left Uncategorized instead of being guessed.
Can we use our own product categories?
Yes. Bring your own category tree, describe each category in plain words and test it on a few of your products, with the reasoning for every choice, before you sort the catalogue. You can keep several trees side by side, and each product keeps its place in every one of them.
Can a product be in more than one category?
Yes, in your own category trees: choose it when you set the tree up, and a product can sit in several categories at once, such as Ceiling lamps and New in.
What are category-level attributes?
Fields you add to a category rather than to single products. A field set on a parent category applies to every subcategory beneath it, with its agent. A subcategory can add fields of its own, or use a different agent for a field set higher up.
Can we correct a category by hand?
Yes. Change it on the product, while reviewing a proposed category, or for many products at once. A product's Google product category follows its category, also after you move it.
