Filters and segments

Filters narrow every page in the dashboard to a slice of your traffic (one country, one device type, one campaign, or a saved cohort) without changing what any number means, only which rows go into it.

#The filter dimensions

Sixteen dimensions, grouped in the filter panel:

Any dimension also has a (none) option, which matches sessions where that field is genuinely empty (a session with no referrer, for instance) rather than excluding them.

#How filters combine

Values within one dimension are OR'd together: picking United States and Germany under Country shows visitors from either. Different dimensions are AND'd: Country = US and Device = mobile narrows to both at once. There's no negation yet: you can select which values to include, not which to exclude.

#Filtering by a cohort

A saved cohort can be applied as a filter too. It sits alongside the sixteen dimensions above rather than being one of them: multiple selected cohorts are OR'd together, and the result is AND'd with whatever other filters are active, the same way an extra dimension would be.

#Filters carry across pages

Your active filters persist in a cookie, so navigating from Overview to Sources to Funnels keeps the same slice applied everywhere without re-selecting it. As with the range, anything explicit in the URL wins over the cookie: following a link with filter parameters in it always honours the link.

#Sharing a filtered view

Because filters live in the URL, copying the address bar and sending it to a teammate reproduces the exact same filtered, ranged view for anyone signed into the same workspace. This does not extend to the public dashboard link covered in Sharing: that surface shows the unfiltered dashboard only, with no way for a recipient to apply or see filters.
