These 12 KPIs were selected to provide a comprehensive view of e-commerce marketing performance, spanning acquisition efficiency, customer behavior, and financial outcomes. They balance leading indicators like Conversion Rate and Shopping Cart Abandonment Rate with lagging metrics such as Net Profit Margin and Customer Lifetime Value, covering the full funnel from visitor engagement through repeat purchase and profitability.

Track Conversion Rate alongside Cost Per Acquisition (CPA) to evaluate acquisition efficiency; rising CPA with flat Conversion Rate signals diminishing channel effectiveness. Monitor Customer Retention Rate and Repeat Purchase Rate together—divergence indicates issues in post-purchase engagement or loyalty programs. Compare Average Order Value (AOV) with Revenue Per Visitor (RPV) to assess whether higher order sizes translate into overall revenue growth or if visitor quality fluctuates.

Prioritize implementing Conversion Rate and CPA first, as these metrics require minimal data integration and provide immediate insight into campaign performance. Follow with Customer Lifetime Value (CLV) to connect acquisition efforts with long-term revenue potential. The full suite of e-commerce marketing KPIs, including advanced operational and financial metrics, is available in the KPI Depot database.

You are only restricted on the quantity of CSV downloads (see questions below).

What's the difference between the Basic and Pro plans?

Both plans include unlimited web access to the full KPI database and benchmark database, interactive Strategy Maps for every KPI group, and 2,000+ OKR examples.

The Basic plan includes 5 CSV downloads per month and is designed for individual research use.

The Pro plan includes 20 CSV downloads per month and unlocks the full deliverable workflow: save your customized Strategy Maps and export them as Balanced Scorecard CSV templates, complete with KPI names, formulas, monthly tracking columns, and links to benchmark data. Open the export in Excel and start tracking immediately.

Can I try the interactive Strategy Map before subscribing?

Yes. Every KPI group includes an interactive Strategy Map that anyone can open, no subscription required. You can add, remove, and rearrange KPIs across the 4 Balanced Scorecard perspectives (Financial, Customer, Internal Process, and Learning & Growth) to build a map tailored to your organization.

Saving your customized map and exporting it as a Balanced Scorecard CSV template are Pro plan features. To help you turn that CSV into a polished, ready-to-track scorecard, we also offer 5 free Balanced Scorecard Excel templates that pair with your export.

Can I download KPI group data as a CSV?

You can purchase additional download credits at any time: $8 each on the Basic plan, $5 each on the Pro plan. Credits never interrupt your workflow, so you'll never be locked out of a download you need mid-project.

Benchmark data is traditionally expensive. Subscription research and advisory services typically run $2,400 to $70,000+ per year, and a single benchmarking assessment can cost $5,000 at nonmember rates. Compiling benchmarks yourself from public sources takes weeks of analyst time per project.

KPI Depot includes unlimited web access to all 34,632 source-attributed benchmarks on every plan, starting at $499 per year. Each benchmark documents its source, company size, time period, industry, geography, and sample size, so your targets hold up under scrutiny.
