Display title - this shows up above the tags in your page.

Tags - these can be added here with the add field, or deleted with the little X. They are all stored in a custom attribute called "tags", so don't delete that attribute!

Advanced, Tags Link to Location - you need to make a search results page somewhere with a search block on it. Point to that page from here and clicking a tag will take you to the search results page showing other pages that have the same tag you clicked on.
