Daily edits by anonymous users is a standardized metric used to measure the number of edits saved by logged-out users in a given day. It's used as a proxy for the rate of overall contribution.

Discussion[edit]

Using IP as an identifier[edit]

The current metric depends on counting IP addresses within the specified period as a proxy for distinct anonymous editors. A unique IP address doesn't necessarily identify a unique user due to IP rotation, IP addresses shared among multiple editors, proxies etc.

Time lag[edit]

As this is a daily metric, a full 24 hours must elapse after the beginning of the date (UTC) in order to calculate an uncensored value.

Edits on deleted pages[edit]

This metric includes edits on existing pages as well as pages that have been or will later be deleted. This allows us to define a metric as stateless, in other words historical values will not change in the future depending on the status of a page (existing/deleted/moved) at the time the metric is computed. Deletion-related activity is tracked via a separate set of metrics.

Edits across all namespaces[edit]

This metric counts activity across all namespaces of a project: whether an edit is a new page creation, a revision to an existing page or a draft, a message left on a talk page or a contribution to a Wikiproject, the edit is counted as a contribution to the project. The metrics is agnostic about the quality, size or purpose of the edit. Specific types of contribution are measured via dedicated metrics or breakdowns.
