These 12 KPIs were selected for the Digital Marketing KPI database to provide a balanced view across the entire funnel, from acquisition (CPA, Cost Per Lead) through engagement (Email Open Rate, Social Media Conversion Rate) to retention and financial impact (CLV, ROI). This set combines leading indicators like MQL and SQL Conversion Rates with lagging measures such as Customer Retention Rate and NPS, ensuring comprehensive performance tracking across operational and financial dimensions.

Monitor Customer Lifetime Value (CLV) alongside Cost per Acquisition (CPA) to assess acquisition efficiency relative to long-term revenue. Track Marketing Qualified Lead (MQL) Conversion Rate in conjunction with Sales Qualified Lead (SQL) Conversion Rate—divergence between these signals misalignment between marketing and sales qualification criteria. A rising Conversion Rate paired with flat or declining ROI indicates potential issues in campaign targeting or cost management rather than visitor engagement.

Prioritize implementing CPA and Conversion Rate first, as these metrics rely on readily available campaign and web analytics data and reveal immediate acquisition and engagement performance. Follow with CLV to connect acquisition efforts to customer profitability, then add ROI for financial validation once cost and revenue attribution mature. The full Digital Marketing KPI set, with detailed formulas and benchmarks, is accessible 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?

Yes. You can download a complete KPI group (which includes all inclusive KPIs and respective attribute data) as a CSV file. To gain a better sense of the KPI data included, you can download a sample CSV file here.

Each CSV download, whether for a KPI group or for benchmarks, consumes 1 of your monthly CSV download credits.

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 35,625 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.
