Groups are used to display information for specific sections of the website. A Group in Siteimprove refers to certain amount of pages with a common element in the URL, breadcrumb or page title. Groups are especially useful if multiple editors are responsible for different areas of the website.
For example, If you are using a link match and wanted to include these 3 pages:
The common element here is /news/. The tool will then find all elements of your website that include /news/ in the URL structure and group them together and create a group name for them that describe the common element, in this case, /news/. You can read this article on how to create Groups in Quality Assurance to help you get started on creating groups for your website.
Note: Any new pages added to the website that fit the criteria of a group, in this case /news/, will be automatically added to the group by Siteimprove at the next website scan.
