What are the most important marketing KPIs?

Analytics should make decisions easier. If it only creates more tabs and dashboards, something is off.

The core set usually includes qualified leads, conversion rate, cost per acquisition, and revenue influence, but the 'right' KPIs are the ones tied to the decision you actually need to make. More metrics rarely means more clarity; it means more places to hide. We pick a short, owned set linked to business objectives, because a dashboard with fifty numbers and no priorities is just noise with a login.

• Define the business question before building the report
• Track meaningful actions like forms, calls, purchases, and qualified leads
• Separate useful signals from vanity metrics
• Connect marketing activity to outcomes
• Review data often enough to change what happens next

How Field Theory helps

• GA4 and Google Tag Manager implementation
• Custom dashboards and reporting systems
• KPI frameworks tied to business goals
• Form, phone, campaign, and conversion tracking
• Clear reporting that helps teams decide what to do next

Good data should not just describe what happened. It should help decide what happens next.
