Your product attributes help give correlating keywords and categories for that item. Product attributes allow filters to keep your product in the most relevant categories. If you are selling a 500 thread count, twin sheet set, then you will want to list that all in attributes. This means when people start filtering through sheets, then yours will come up for twin as size and 500 as thread count.nnThis means for your SEO, there is an increase in relevant sales. People looking for very specific products will be able to find your product. Those looking for general ones under any of the attributes also potentially allows you to be found then too. Higher visibility…higher sales.
