Product or service categories: Specific marketplace segments may have higher or lower churn based on demand.
2. Repeat Usage Rate
Definition: The percentage of customers who make more than one transaction or visit the platform repeatedly within a specific timeframe.
Formula: Repeat Usage Rate=Number of customers who made a repeat purchaseTotal number of customers×100\text{Repeat Usage Rate} = \frac{\text{Number of customers who made a repeat purchase}}{\text{Total number of customers}} \times 100Repeat Usage Rate=Total number of customersNumber of customers who made a repeat purchase×100
Key Indicators:
Frequency of Repeat Purchases: Number of transactions by a user over a given period (e.g., monthly or quarterly).
Repeat Customer Rate: Percentage of customers who return and make subsequent purchases after their first transaction.
Average Order Value (AOV) for Repeat Customers: Higher values suggest that repeat customers are engaged and spending more on the platform.

Customer Advocacy: Promoters who recommend the marketplace are more likely to return and engage regularly.
4. Customer Retention Rate
Definition: The percentage of users who continue to engage with the platform over a specified period.
Formula: Retention Rate=Number of retained customersTotal customers at the start of the period×100\text{Retention Rate} = \frac{\text{Number of retained customers}}{\text{Total customers at the start of the period}} \times 100Retention Rate=Total customers at the start of the periodNumber of retained customers×100
Key Indicators:
Time Period for Retention: Evaluate retention over different timeframes (e.g., 30 days, 6 months, 1 year).
Churn vs. Retention: Compare churn rates with retention rates to gauge platform health.
5. Engagement Rate
Definition: A metric for how often users interact with the marketplace, including visits, clicks, purchases, and other actions.
Formula: Engagement Rate=Total interactions (clicks, purchases, etc.)Total users×100\text{Engagement Rate} = \frac{\text{Total interactions (clicks, purchases, etc.)}}{\text{Total users}} \times 100Engagement Rate=Total usersTotal interactions (clicks, purchases, etc.)×100
Key Indicators:
Average Session Duration: Longer durations can indicate higher repeat engagement.
Bounce Rate: Lower bounce rates suggest customers are more likely to return.
Product Interaction: Engagement with product listings, reviews, and recommendations can drive repeat usage.
6. Repeat Purchase Cycle
Definition: The time it takes for a customer to make a second (or third) purchase.
Formula: Repeat Purchase Cycle=Total time between first and second purchaseNumber of customers making repeat purchases\text{Repeat Purchase Cycle} = \frac{\text{Total time between first and second purchase}}{\text{Number of customers making repeat purchases}}Repeat Purchase Cycle=Number of customers making repeat purchasesTotal time between first and second purchase
Key Indicators:
Shorter Cycles: A short repeat purchase cycle indicates frequent repeat usage, which is a positive sign for the business.

7. Customer Segmentation by Lifetime Value (CLV)
Definition: The total revenue generated from a customer over the duration of their relationship with the platform.

Segment CLV by behavior: Focus on high CLV customers who are likely to have low churn and high repeat usage.
CLV vs. CAC (Customer Acquisition Cost): An important comparison for assessing how much investment is needed to acquire long-term users.
8. Time to First Repeat Purchase
Definition: The time it takes for a new customer to make a repeat purchase after their first.
Formula: Time to First Repeat Purchase=Date of second purchase−Date of first purchase\text{Time to First Repeat Purchase} = \text{Date of second purchase} - \text{Date of first purchase}Time to First Repeat Purchase=Date of second purchase−Date of first purchase
Key Indicators:
Shorter timeframes: Indicates higher repeat usage and stronger customer engagement.
Incentivization impact: Discounts, loyalty programs, and targeted emails can reduce time to first repeat purchase.
