Tags are used for more specific keywords or targeted phrases that someone might be searching for on Google. If a user starts to type a word that matches with a tag that is already been used, it will show a suggestion which can be used as a tag. This is an easy way of trying to keep the tags organized, thus avoiding duplicate tags.
Following are some of the main key differences between Tags and Categories:
Using Edit link, the user can make changes to the Tag and can update those changes using Update button as shown in the image below.
Using Quick Edit, the user can make changes to the tag quickly in the same window without redirecting to another page as shown in the image below.
Using Delete link, the user can delete the Tag. Clicking on the link will display a popup window providing two options OK and Cancel, proceed by clicking Ok to delete the tag or cancel the process. The image below displays the Popup window:
Using the View link, the user can view the preview of the tag on the site. The image below displays the View link for tag.
