If you have the e commerce website which has the immense categories to offer and you find them to be messy and unstructured. The product categorization and tagging is the ultimate service for you. As it provides the ease to visitors of the website in finding the product they have been looking for.
The categorization is usually done on the basis of features, color, sizes, etc. hence it simplifies the filter methodology. When a user is stuck with so many options and alternates it becomes tedious for them to browse and in turn their visiting time lessens. But such a process of categorization & tagging resolves the issues of the consumer and the owner both. It even aids one in finding the niche products by having the segmented product section.
