Marketplace analytics that survive seasonality
Take-rate, GMV, buyer-LTV vs seller-LTV — and the supply-side health curves your ops team won't let you skip.
Marketplace · metric tree
- M-01
GMV
By segment, by category, by cohort. Reconciled to the payments table at the cents level.
- M-02
Take rate
Net of fees, refunds, and incentives. Promotion contribution backed out so margin is honest.
- M-03
Buyer & seller LTV
Cohorted by acquisition channel, with churn defined uniformly across both sides.
- M-04
Repeat-purchase rate
30-day, 90-day, 365-day. The leading indicator of channel quality.
- M-05
Funnel from search
Search → SRP → PDP → cart → checkout. Drop-off by category, by device, by bucketed PDP latency.
How it ships
Postgres + dbt + Snowflake + reverse-ETL to the ops console for daily seller cohort tactics.
outcome
Promotions that look great in the dashboard but eat margin get caught in the same pull request that changes them.
