Merge Tags
A Merge Tag is a small placeholder tag, that may consist of a few words or strings of text, which you can add to any page on your help site. The text you add to the page is not formatted and is stored as plain-text on publishing the page.
Merge tags are flexible and reusable, making it simple to make site-wide changes by editing the merge tag source instead of having to modify many pages, separately.
Types of Tags
There are two types of merge tags:
1. System merge tags - These are pre-defined tags that you can re-use to quickly update a page’s content. You cannot alter or edit these tags. 
2. Custom merge tags - Custom tags are those tags that you can create as per your requirements and add them to pages on your help site.
