Hello Sahnoor Alam,
No changes are necessary to the footer static blocks tags element that has been assigned to your products. These tags can be found under the Products >> Tags section.
If you would like to edit the trending tags, you can simply add or remove product tags under the Products >> Tags section and assign or unassign them from your products.
