Primary category
A product can be in as many categories as you want. The primary category tells the store which of them is the actual one — the one to be used when only one can be chosen.
Why it's worth setting
Without a primary category, the store guesses. It chooses the first active category the product is in, and 'the first' is not something you control. A product that is in both Offers and Running Shoes can then be reported to Google as an offer rather than a shoe.
These are the places where the choice has an impact:
Where | What the primary category controls |
|---|---|
Product page | The breadcrumb trail. A customer who lands directly on the product from Google or an ad will see the category path — without a primary category, they won't get one |
Google Shopping | Product category and product type in the feed. The wrong category here leads to poorer ad targeting |
Klaviyo | The same category follows the product into emails |
Recommendations | Which category the product is considered when the store suggests similar items |
Search | The product carries its category into the search index |
Orders and statistics | The category that follows the item line into Google Analytics |
The Trend Report | Whether the product is counted once or in every category it belongs to |
The Trend Report is the clearest: a product without a primary category is counted with full revenue in all its categories. If a jacket is in both Jackets, Women, and New Arrivals, all three get the full sale. The figures per category then become higher than what the store actually sold for.
💡 One category per product
A product can only have one primary category. If you set a new one, the old one automatically loses the tag.
How to set a primary category for one product
1. Go to Products → Products and open the product
2. Find Categories in the product card — the categories the product belongs to are listed
3. Click on the star in front of the category you want to make the primary category
The star fills in when selected. The change is saved immediately; you don't need to save the product afterward.
How to set a primary category for many products simultaneously
Bulk editor does the job for entire product lists. The smart order is to first find the products that are missing a primary category, and then set it for them.
Find the products that are missing it
1. Go to Products → Bulk editor
2. Add the filter Has primary category and select No
3. Add the filter Categories and select the category you want to work with
Now you are left with the products in one category that do not have a primary category. This is the list you want to change.
Set the category
1. Select the products you want to change
2. Select the action Change categories
3. Set Action to Add
4. Select the category under Primary category
5. Run the action
All selected products will have the same primary category. Therefore, the filtering above is important: do one category at a time to ensure accuracy.
If the category you select is not already a primary category for the product, it will be added automatically. This field is optional — if you leave it empty, the action will only change which categories the product is in, and the primary category will remain as it was.
⚠️ "Replace with" removes all other categories
The action Replace with removes the product from all categories it is currently in, and places it only in those you have selected. If you only want to set a primary category, use Add
Tip
- Choose the category the customer would look for, not the one that sells best. The primary category should describe the product, not market it.
- Campaign and seasonal categories such as Offers, New Arrivals, and Black Friday are rarely suitable as primary categories. They change content, while the product remains the same.
- If you have many products without a primary category, take one main category at a time rather than the entire store in one operation. Then you will see the result before proceeding.
- The filter Has primary category does not find products that are not in any category at all. They must first be placed in a category before they appear.
