Project analytics
Project Analytics helps you understand how people use a site after it is published. Open the project workspace and select More → Analytics.
Analytics can collect visits when the project is live, Visitor analytics is enabled, and the visitor has chosen Allow analytics on that hostname. The project setting is enabled by default, but no analytics event or session cookie is created before the visitor’s choice. Preview visits are not counted, and an unpublished project does not collect new traffic.
Analytics uses pseudonymous browser sessions for consented traffic totals. It does not identify visitors or create a persistent profile that follows someone across separate visits.
View your traffic
Publish the project
Analytics needs a live site. If the project is not published, the Analytics page shows a Publish action instead of traffic.
Open Analytics
Select More → Analytics. Traffic from the project’s *.r21.dev address
and connected custom domains appears in the same dashboard.
Metrics
A one-page visit has a recorded duration of zero because there is no second page view to measure against.
Breakdowns
- Source shows where a visit began. Visits with no usable external referrer appear as Direct.
- Page shows which paths visitors opened.
- Device groups visits into Desktop, Mobile, or Tablet.
- Country shows a coarse country result when one is available, otherwise Unknown.
These totals describe recorded browser traffic, not every request to the site. Tracking protection, rejected or undecided consent, disabled JavaScript, network failures, and automated-traffic filtering can make Analytics totals lower than server request counts.
Turn Visitor analytics off or on
When analytics is disabled, More → Analytics shows an Enable Analytics action. Turning it back on collects new traffic from that point forward; it does not recreate visits from the disabled period.
Existing history remains available until it reaches the 90-day retention period or the project is deleted. Unpublishing also stops new collection.
Visitor choices
A live analytics-enabled site offers Allow analytics and Reject analytics before collection. The choice is remembered on that hostname for up to 180 days. Visitors can reopen Cookie preferences and change it at any time. Rejection or withdrawal stops new events and clears the 30-minute session cookie. Clearing or expiring the preference returns collection to the undecided state.
The preference applies to Mythos’s built-in analytics only. As the site owner, you remain responsible for your application notice and any additional tracking or third-party code you add. See the Privacy Policy, Cookie Policy and Data Processing Agreement.
