You can think of tags as filterable bits a metadata that you can assign to locations such as "Free WiFi" or "Public Restrooms".
The tags you assign to locations can then be filtered in the sidebar of the integration.
Locations that don't have chosen tag associated will be filtered out, making it easier for your users to find what they are looking for
Tags are managed at the map level since they can be applied to more than one location. To add a tag go to the Tag Settings page and Select "New Tag".
Once you've added some tags they can then be selected at on the individual Location Settings page.
