Digital business KPIs: what to measure

The metrics that truly matter for making informed decisions in your digital business

9 min

Measuring everything is as useless as measuring nothing. KPIs (Key Performance Indicators) are the specific metrics that tell you whether your digital business is progressing toward its goals. Not all metrics are KPIs: only those directly linked to your strategic objectives deserve that status.

This guide helps you select, configure and act on the KPIs that genuinely matter for your digital business, whether it’s a corporate website, an ecommerce store or a SaaS platform.

How to define KPIs that work

A good KPI meets the SMART criteria: Specific, Measurable, Achievable, Relevant and Time-bound. "Increase traffic" is not a KPI; "Grow organic traffic by 30% in Q2 2026" is.

Limit your KPIs to 5–8 primary ones. Any more dilutes focus. Each KPI should have an owner (the person responsible for moving it), a review frequency and a quantified target.

  • Link each KPI to a concrete business objective
  • Define a numeric target and a deadline
  • Assign an owner who monitors and acts on the KPI
  • Set thresholds: green (on track), amber (at risk), red (off target)

Revenue and profitability KPIs

These are the metrics that matter most to leadership and investors. They measure the financial health of your digital channel and its contribution to the overall business.

  • Revenue: total income generated by the digital channel
  • MRR / ARR: monthly or annual recurring revenue (critical for SaaS)
  • AOV (Average Order Value): average value per order in ecommerce
  • CAC (Customer Acquisition Cost): how much it costs to acquire a new customer
  • LTV (Lifetime Value): total value a customer generates over the course of the relationship
  • LTV/CAC ratio: should be at least 3:1 for a sustainable business

Traffic and acquisition KPIs

Traffic metrics measure your digital channel’s ability to attract qualified visitors. Volume matters, but quality and source matter more.

  • Total sessions and unique users (monthly trend)
  • Traffic by channel: organic, paid, direct, referral, social, email
  • Organic traffic as % of total: indicates the health of your SEO strategy
  • Cost per click (CPC) and cost per acquisition (CPA) in paid campaigns
  • Bounce rate by landing page: indicates whether arriving traffic is relevant

Conversion KPIs

Conversion is where traffic turns into value. You can have millions of visits, but if they don’t convert, your digital channel isn’t fulfilling its function. Measure conversion at each funnel stage to identify where users drop off.

  • Overall conversion rate: visitors who complete the primary goal (purchase, signup, contact)
  • Funnel stage conversion rate: visit → lead → opportunity → customer
  • Cart abandonment rate: in ecommerce, typically between 60–80%
  • Conversion rate by device: many sites convert well on desktop but poorly on mobile
  • Micro-conversions: newsletter signups, downloads, demo requests

Engagement and retention KPIs

These metrics measure how users interact with your product or content once acquired. They’re especially important for SaaS, apps and subscription models.

  • DAU / MAU (Daily/Monthly Active Users): active users, essential for apps and SaaS
  • Churn rate: percentage of customers who cancel in a given period. Keeping it below 5% monthly is the standard goal
  • NPS (Net Promoter Score): likelihood that your customers will recommend you
  • Pages per session and average time on page: indicate content interest
  • Return rate: percentage of users who come back within 30 days

Tools and dashboards

KPIs only work if they’re visible and reviewed regularly. Centralise your metrics in a dashboard the team can check at any time. Avoid spreadsheets as your primary reporting tool: they don’t scale and create conflicting versions.

  • Google Analytics 4: traffic, conversions and web behaviour (free)
  • Looker Studio (Google Data Studio): visual dashboards connected to multiple sources
  • HubSpot / CRM dashboards: integrated sales and marketing metrics
  • Mixpanel or Amplitude: product analytics for SaaS and apps
  • Databox or Klipfolio: multi-source dashboards for marketing teams and leadership

Key Takeaways

  • Limit your KPIs to 5–8 metrics directly linked to business objectives
  • The LTV/CAC ratio should be at least 3:1 for sustainable acquisition
  • Measure conversion at each funnel stage to identify where you lose users
  • Engagement and retention metrics are as important as acquisition metrics
  • Centralise KPIs in a dashboard visible to the whole team, not in spreadsheets
