Learn to use the visitors dashboard to manage your visitors
The visitor dashboard allows you to see all visitors to your site, both anonymous and non-anonymous. You can also check the attributes of each visitor and search through your visitors to enrich your visitor information.
A visitor can be subscribed multiple times: for each browsers he is identified.
You cannot add visitors manually
It is impossible to create visitors manually, they can only be visitors of your site.
A user is considered anonymous as long as his key has not been defined manually by a
setKey. This represents a visitor that you are not able to link to one of your users. Anonymous users do not appear in the advanced statistics & it is not possible to search with them.
As soon as you defined a key for a visitor with the userData.setKey the visitor won't be an anonymous user anymore.
