Who comes back

Each row is a Monday-start week of first visits. The cells are the share of that group with a page view in a later week.

Weekly cohorts

Each row is the week of a visitor’s first stored page view.

The week rule

  1. Take stored page views. Leave out crawler and headless rows.
  2. A week starts Monday 00:00 UTC. The cohort week is the earliest week for that anonymous visitor.
  3. Week 0 is everyone in the cohort, so it is 100%. Week k is the share who have any page view in the Monday that is k weeks later.
  4. The grid keeps the latest eight cohorts and six week offsets. A later week that has not happened yet stays at 0, which is not the same as a measured return of zero people.
