Unique visitors

The ‘Unique visitors’ metric shows the number of visitor IDs for the dimension item. It is one of the most common metrics used when determining traffic, as it gives a high-level overview of the popularity of a dimension item. For example, a visitor can come to your site every day for a month, but they still count as a single unique visitor.

If you use Cross-device analytics, this metric is replaced with the Unique devices metric.

Daily, weekly, monthly, quarterly, and yearly unique visitors

Analysis Workspace treats unique visitors based on the granularity of the report. For example, if you use the Day dimension, you’ll see daily unique visitors for each dimension item. However, for the report total, it is deduplicated unique visitors for the freeform table’s date range.

How this metric is calculated
