How to interpret this result

Share of shoppers who reorder under your cohort rules.

Acquisition-heavy stretches mechanically depress the headline even if loyal buyers still return.

Common mistakes

  • Labeling subscriptions as repeats when counting first payment only elsewhere.
  • Pooling wholesale and ecommerce behaviors without admitting it.
  • Including ghosts who never fulfilled as “customers.”

What to do next

Visit LTV-lite or churn-style reads when repeats matter alongside acquisition.

How to improve this result

  • Launch replenishment reminders responsibly when ethically appropriate.
  • Incent bundles when repeat uplift stagnates mechanically.
  • Understand acquisition-heavy months artificially depressing repeats short term.
