What are the difference between Tag & Category in WordPress?
In WordPress categories are hierarchical which means terms can have a relationship with each other like child and parent.
Example: You could have a Category called India, and under India, you could have categories called Delhi, Haryana, and U.P. Categories means for broad grouping of posts.
But Tags are NOT hierarchical which means no relationship between them. Tags means to describe specific details posts.
