repeat supplier rate, repeat-success seller share

Formula

sellers_with_subsequent_success / eligible_sellers_with_initial_success × 100%

Metric card

Unit% of sellers
Data sourceSeller cohorts, eligibility, deduplicated identifiers, terminal success events, and event dates.
FrequencyBy first-success cohort after the repeat window closes.
Segmentsmicro-market, category, seller type, acquisition channel, cohort, quality tier

Interpretation errors

  • Substituting a repeat login or listing for a repeat successful outcome.
  • Including sellers who lost eligibility before the repeat window without an explicit rule.
  • Hiding demand dilution behind aggregate repeat transaction volume.

Example

Illustrative example: 30 of 100 sellers with an initial success achieve another success in the window, producing a 30% rate.

Use

Separate repeat activity from repeat useful outcomes. Report repeat beside seller availability, relevant opportunities, and supply-side success probability.

Anti-example

Republishing listings is not seller repeat when the metric’s success event is a completed transaction or qualified match.

Limitations

  • The metric depends on category lifecycle, eligibility, and window length.
  • Low repeat may reflect seasonality or finite inventory rather than platform deterioration.
