If you need to segment your products then you can use a few options here.
When you need to separate your products by a brand it is best to use our Brands section to create all the brands that you are selling there.

In case you need to categorize your products depending on the specific attributes they carry then you can use the Categories option.

And the last but not the least important feature in product segmentation is tags. You can add tags to each product your are selling in case they need some additional specifications that are not suitable through Brands or Categories. To add tags simply go to Products > Product Actions > Add New Product and from there scroll down to see the tags option.
