The category is the aisle your product is shelved in. Many buyers never use the search bar: they browse from category to category. If your product is filed in the wrong place, those buyers will never come across it.
File it where the customer looks
The natural instinct is to pick the category that seems logical to you. The right instinct is to pick the one your customer will look in. They are not always the same thing.
- Choose the most specific category available rather than a catch-all one.
- If the marketplace allows it, add a sub-category: it sharpens the classification further.
- Check where similar products that sell well are filed: they point you to the right aisle.
Tags complete the category
On top of the category, tags (or secondary keywords) describe cross-cutting attributes: material, colour, occasion, style. They multiply the ways buyers can reach your listing.
Example: a wool scarf can sit in the « Accessories » category with the tags « wool », « handmade » and « winter gift ». A buyer searching for a « winter gift » finds it, even without going through the main category.
Key takeaway: file every product in the most specific category, where your customer really looks, and add tags to multiply the paths leading to your listing.
