Board metrics

Sessions

A session is a run of events on the same first-party visitor_id with no gap longer than 30 minutes. The snippet also keeps a sessionStorage session id for the tab; the board number uses the 30-minute gap on timestamps, not that tab id.

Bounce rate

Sessions that contain exactly one pageview, divided by sessions. No sessions → the tile is —, not 0%.

Conversion rate

Visitors with at least one purchase, divided by visitors in the selected range. No visitors → —. Amount is rand, not cents.

Avg session duration

First event to last event in each session, in seconds, then the mean. A single-event session is 0 seconds.

New vs returning

Returning means that visitor_id was seen before the start of the selected 7d or 30d window. All-time has no prior window, so everyone is new. The First visit / Returning chip uses that same definition. Returning stays off on all-time because there is no prior window to count against. This is first-party localStorage, not a cookie. Clearing site data starts a new visitor. See cookieless and hostnames.

Pageviews

Count of stored pageview events in the range. Shown next to Visitors / ZAR / RPV. Those three stay the pin-able #1 KPIs.

Versus previous period

On 7d and 30d a small percent (visitors, ZAR, RPV, sessions, pageviews) or percentage-point (bounce, conversion) delta sits under the tile. A custom from/to range uses Africa/Johannesburg calendar days and a prior window of the same length. Hidden when that prior window has no events or is not well-defined. All-time has no prior window. No paid timezone database.

Pin and filters

Click a row on Pages, Referrers, Devices, Browsers, OS, Campaigns, UTM term, UTM content, Hostnames, Cities, Regions, Entry, or Exit to compose a filter. Chips remove one constraint. Empty after a filter means no matching events — not a sample.
