Glossary
Attribution
Section titled “Attribution”A revenue event is credited to the visit it fired in, and inherits that visit’s source, campaign, landing page, country and device. There is no later matching and no unattributed bucket. → How attribution works
Average order
Section titled “Average order”Revenue ÷ transactions, for one currency, over the filtered slice.
Bounce
Section titled “Bounce”A visit with one or fewer pageviews. Custom events, outbound clicks and revenue events do not clear the flag.
Breakdown
Section titled “Breakdown”A ranked list of one dimension’s values. Ranked by unique visitors, with the raw event count alongside. → Breakdown
Cohort
Section titled “Cohort”In Retention, everyone whose first activity inside the range fell in the same day or week.
Conversion
Section titled “Conversion”A hit that matches a goal — an event by name, or a pageview by path pattern.
Converter
Section titled “Converter”A distinct visitor who converted, as opposed to a conversion, which is one matching hit.
Coverage
Section titled “Coverage”Two meanings. For a property key: the share of that event’s occurrences carrying the key. For identity: the share of visitors who left a durable trait.
Cumulative
Section titled “Cumulative”On the revenue chart, the running total of revenue from the start of the requested range. Not a lifetime total.
Customer
Section titled “Customer”On the Revenue screen, a distinct visitor id that reported at least one amount in the range. In the default mode that is a browser-day.
Dimension
Section titled “Dimension”Something you can group by. Twenty-one of them, each mapping to a filter key of the same name. → Filters & dimensions
Direct / none
Section titled “Direct / none”The breakdown label for a hit with no referrer. Passing that literal string as
referrer selects those rows.
Drop-off
Section titled “Drop-off”In a funnel, visitors who reached a step but not the next one. The drop-off panel shows where they went instead.
Duration hit
Section titled “Duration hit”The time-on-page flush sent when a tab is hidden. It is not an event: the collector adds the milliseconds to the pageview they belong to and writes no row.
Entry / exit page
Section titled “Entry / exit page”The first and last path of a visit. Both are session-level, so breakdowns on them count sessions, not visitors.
Any hit written to the events table: pageview, custom, outbound or
revenue. The Events screen shows only the named ones.
Filter
Section titled “Filter”A query-string parameter that narrows every number on a screen. Twenty-six keys, combined with AND. → Filters
A named conversion — an event name, or a path pattern with * wildcards.
Hash mode
Section titled “Hash mode”The default, cookieless identity mode. The visitor id is a daily salted hash computed server-side. → How visitors are counted
Identified
Section titled “Identified”A visitor carrying a durable id through
tracing.identify(). Retention keys on userId,
user_id, id or email; the Sessions column uses a wider display list.
Identity probe
Section titled “Identity probe”GET /c/:key. The request the tracker makes before its first hit to learn the
site’s identity mode.
Minor units
Section titled “Minor units”The smallest unit of a currency. Usually 1/100, but 1/1 for JPY and KRW and 1/1000 for KWD and BHD. Every amount in the product is in minor units.
In a journey column, everything outside the top six — kept so the column still totals the number of visits.
Overage
Section titled “Overage”Events past the plan’s monthly allowance, billed per 100,000 with part-blocks rounded up. → Usage & overage
Pageview
Section titled “Pageview”A hit of type pageview. Sent automatically on load and on every History API
navigation.
Previous period
Section titled “Previous period”The window of exactly the same length ending where the current range starts. Every delta compares against it.
Property
Section titled “Property”A key/value pair on a custom event. Stored twice — as JSON on the event, and flattened so it can be grouped on.
Public key
Section titled “Public key”pk_live_ plus eight hex characters. The site id in your script tag. Public by
design.
Session
Section titled “Session”See visit.
Share id
Section titled “Share id”The 12-character random id in a public dashboard URL. Toggling sharing off and on mints a new one.
A key/value pair attached to a visitor by tracing.identify(), upserted per
(site, visitor, key).
Revenue event
Section titled “Revenue event”An event that carries an amount and a currency, sent as
tracing("purchase", { revenue, currency }) or tracing.revenue(). The only
source of money in the product.
→ Revenue events
Transaction
Section titled “Transaction”One revenue event. The Revenue screen counts them and lists them.
Views per visit
Section titled “Views per visit”Pageviews ÷ visits over the filtered slice.
A run of activity by one visitor with no gap longer than 30 minutes. Called a session in the database and the API, a visit in the UI.
Visitor
Section titled “Visitor”A distinct visitor id in the slice. In the default mode that is a browser-day — read How visitors are counted before using the number.
Visitor share
Section titled “Visitor share”For an event, the percentage of the range’s visitors who fired it at least once.
