What is a good or service tag?

It is very common that many products come up with the same topics or features. But to have a better general structure and easier use for users, we should be able to categorize the similarities which are not specified in our general categorization. Here, the concept of “tag” comes up. In fact, we just need to create one tag for our intended topic or feature and label it on all related products. Each tag creates one page on our website that includes all related products. Actually, tag’s function is just like the categorization, with the difference of less importance and it is not meant to be placed on the main page of the site. Therefore, it is suggested to consider a tag for each category that contains products with similar features, before inserting your product’s information on the site.
