The Trends dashboard allows measuring the evolution of the traffic metrics ( over a period of time. It includes all metrics described in the article Traffic metrics, except for New/Returning Visitors.
It allows visualizing one metric at a time, by selecting it from a menu on the top of the main timeline chart.
The timeline chart presents the value of the metric computed over Time Unit, represented on the X-axis. The Time Unit can be a day, a week or a month. The available choices for the Time Unit depend on the extent of the total Observation Period.
For example, when representing the time series of the Visitors, each value on the chart represents the number of individuals who made at least one visit in the Time Unit (for example in the same day). If an individual makes distinct Visits in multiple distinct days, then this is counted as a Visitor for each day (or in each Time Unit in general).
Using the dashboards
All the dashboards allow to measure the metrics on the page over a customizable period of time and aggregate the data across all the Locations or inspect each individual Location.
You can choose the Observation Period from the top of the page, select all the Locations of the Organization or pick one specific Location at a time.
All the metrics are compared with the value of the same metric computed over the Previous Period, defined as the period of the same amount of days immediately before and adjacent to the Observation Period.
