Evolution
The Evolution report shows how your metrics change over time, with flexible grouping and UTM filtering.
Accessing the Report
- Select a site from the site selector
- Click Evolution in the sidebar
URL pattern: /sites/{site_id}/evolution
Time Grouping
Control how data is aggregated using the grouping selector (By Hour, By Day, By Week, By Month):
| Grouping | Best For |
|---|---|
| By Hour | Very short periods, intraday patterns. Rows are grouped by day and expand to show individual hours |
| By Day | Short periods (7-30 days), daily patterns |
| By Week | Medium periods (1-3 months), weekly trends |
| By Month | Long periods (6+ months), seasonal analysis |
UTM Filters
Filter data by specific traffic sources:
Available Filters
| Filter | Description | Example |
|---|---|---|
| UTM Source | Traffic source | google, facebook, newsletter |
| UTM Medium | Traffic medium | cpc, organic, email |
| UTM Campaign | Campaign name | black-friday-2025, brand-awareness |
Applying UTM Filters
- Click the Filters button to open the filter panel
- Choose a value from the Source, Medium, and/or Campaign dropdowns (one value per dropdown)
- Data updates to show only matching traffic
- Active filters appear as removable chips below the toolbar; the Filters button shows a count badge
Combining Filters
Filters combine with AND logic:
- Source = "google" AND Medium = "cpc" shows only Google Ads traffic
- Add Campaign = "brand-2025" to narrow further
