How to Change Old WordPress Tags

1. Log into your WordPress account. Click 'Posts' and scroll through your list of posts until you find the one with tags you want to edit. Click the name of the post.
2. Remove old tags you've deemed redundant, ineffective or that you otherwise want to remove. Scroll down the right side of the page until you reach your list of tags and click the gray 'X' next to a given tag to remove it from your post.

3. Add new tags to replace ones you delete. Enter a word or phrase you want to use as a tag into the 'Post Tag' field, separating tags from one another using commas. Click 'Add' to add these tags to your post. Click 'Update' to update your post to reflect new tags.
