Marketplace Metrics & KPIs Library
70+ indicators and everything you need to know and measure to be succesful with your Marketplace and e-commerse solution
Welcome to this week's newsletter ⛰️. As I launch my first paid newsletter issue, I wanted to provide the most comprehensive overview of metrics and key performance indicators (KPIs) for marketplaces and e-commerce platforms. My goal is to examine these metrics in depth with real-world examples and insights.
I spent several days gathering perspectives from diverse sources including Stripe, Shopify, venture capital firms like Andreessen Horowitz, renowned education platforms such as Reforge, and popular newsletters (more than 10 newsletters issues including Lenny’s and many others). While each provided valuable insights, I found them incomplete in covering everything you can measure for marketplaces and e-commerce (they are really good as a summary but they cannot cover everything). Much of the focus tends to be heavily weighted towards either usage KPIs or business KPIs exclusively but almost none combine both with all the qualitative data that you can gather too.
To address this gap, I have synthesized and compiled the key metrics from both categories with relevant examples into one reference guide. Consider it your marketplace metrics library covering both usage and business KPIs in a single place, saving you from having to search across multiple sources. Let's dive in 🌊
Why Marketplace Metrics are so important
Marketplace metrics provide the compass for sustainable growth. By converting operational data into actionable insights, key metrics reveal marketplace health, opportunities, and strategy. Metrics empower informed decisions through quantitative evaluation of performance over time. Data-driven marketplaces demonstrate higher profitability, so granular metrics become a strategic asset for stability and growth. However, with many potential metrics to consider, focus is essential. Marketplaces should prioritize metrics tied to core goals, growth stage, and competitive landscape and this can change depending on the type of Marketplace and the goals of the same. I will include all the metrics and KPIs available, with examples, and I will provide my take when it comes to picking my top 3 KPIs (if you can only get 3 of the 70+ of the library). But before we go there, let’s review some key definitions that we will need:
Difference between metrics and KPIs
Let’s start with the key differences between the two:
Marketplace Metrics
Any measurement related to the performance or health of a marketplace business (there are neither "good" nor "bad")
May not directly correlate with core business objectives or success.
Help provide overall context, but don't necessarily indicate performance.
Examples: things like website traffic, social media followers, etc.
Marketplace KPIs
Vital metrics tied directly to the key goals and objectives of the marketplace.
Measure performance for core activities that drive business success.
Things like revenue, customer acquisition costs, retention rates, etc.
Offer actionable insights into what's working well and what needs improvement.
Help track performance on marketplace growth, profitability, and operations. Guide decisions.
Examples: Revenue, Customer Acquisition Costs, Lifetime Value, and Take Rate.
In essence, all KPIs are metrics, but not all metrics are KPIs. KPIs specifically track performance and progress on the most important marketplace goals and outcomes. Metrics more broadly encompass any business measurement, only some of which provide meaningful performance insights.
Businesses need to track both overall marketplace metrics for health monitoring and contextual awareness, as well as marketplace KPIs carefully selected to illuminate progress towards strategic goals, growth, and profitability. Aligning metrics and KPIs with clear business objectives is crucial for accurately gauging performance.
Now that we know the difference, let’s see some key concepts that will help with any KPI or metric (and if you don’t know you should know as a PM):
Key concepts for metrics and KPIs
Vanity Metrics
Metrics that make a company look good but don't actually measure business success or progress towards goals. Things like social media followers, website visitors, and app downloads.
Can boost morale but doesn't help guide core business decisions or strategy. Need to focus on actionable metrics.
North Star Metric
The single most important, high-level metric that captures the core value a marketplace delivers.
Provides an unambiguous measure of progress towards the primary strategic goal.
Network Effects
Marketplaces become more valuable as they have more users/buyers/sellers and inventory. The beneficial cycle reinforces growth.
Metrics should show improving health over time as networks expand - engagement, conversion, and liquidity.
Liquidity
Measures if the marketplace has enough buy/sell volume for matches (completed transactions) to happen easily and quickly.
Impacts the experience in the marketplace (imagine a marketplace without enough sellers or almost with no inventory)
Metrics like time to match, market depth, and concentration reveal liquidity dynamics.
Match
The successful completion of a transaction between a buyer and seller on the marketplace. Measures liquidity.
Key liquidity metric showing the marketplace's ability to efficiently connect supply and demand. Low match rates signal issues.
Product Market Fit
Indicates how well the marketplace meets the needs of participants for facilitating transactions.
Measured by metrics like Sean Ellis Test surveying users on how disappointed they'd be losing access. High scores show the marketplace provides high utility and value.
Benchmarking
Comparing marketplace metrics over time and against competitors provides context and positioning.
Sets performance targets based on trends and standards. Helps identify maturity trajectory.
Finally, we can study all the key Marketplace metrics that we wanted to study.
