Glossary Term

Metric

glossary metric featured

A metric is a quantitative measurement of your data, expressed as a number. It counts, sums, or averages activity, answering “how many” or “how much.” Examples include Sessions, Users, Conversions, and Revenue. In analytics reports, metrics are the values you measure against a dimension.

Metrics vs Dimensions

Metrics measure data; dimensions describe it. This pairing is the foundation of every analytics report.

A metric is always a number, like 4,210 sessions or $8,500 revenue. A dimension is the category that number is grouped by, like Country or Source. Reports combine them: dimensions become the rows, metrics fill the columns.

Look at one row in a GA4 report: “facebook | 1,820 sessions | 64 conversions.” Here “facebook” is a dimension value, while “1,820” and “64” are metrics. Swap the dimension and the metrics redistribute. Add a metric and a new column appears.

The simplest test: if you can add it up, it is a metric. If it labels the total, it is a dimension.

Types of Metrics

Metrics fall into three structural types based on how they are calculated:

  • Count metrics. A raw tally of events. Examples: Sessions, Users, Event count, Pageviews.
  • Sum metrics. A total of values. Examples: Revenue, Total ad spend, Purchase value.
  • Ratio and average metrics. A calculation between two numbers. Examples: Conversion rate, Bounce rate, Average engagement time, Average order value.

GA4 also lets you build custom metrics from numeric event parameters, such as a score or loan_amount you send with an event. Use these when no built-in metric captures your number.

Common Marketing Metrics

Marketing metrics measure the performance of campaigns, channels, and content. They cluster around four stages of the funnel:

  • Acquisition. Click-through rate (CTR), cost per click (CPC), impressions, sessions by source.
  • Engagement. Engagement rate, average engagement time, pages per session, bounce rate.
  • Conversion. Conversion rate, cost per lead (CPL), cost per acquisition (CPA).
  • Revenue. Return on ad spend (ROAS), average order value (AOV), customer lifetime value (LTV).

If you tag campaign links, linkutm’s analytics dashboard reports click metrics by source, medium, and campaign, so paid and organic numbers sit beside your GA4 data.

KPI vs Metric

A KPI is a metric tied to a specific business goal. Every KPI is a metric, but most metrics are not KPIs.

A metric is any number you can measure. A key performance indicator (KPI) is the small set of metrics that signal whether you are hitting a target. Pageviews is a metric. “Pageviews per month, target 50,000” is a KPI, because it has a goal and a deadline attached.

The practical difference is focus. You track dozens of metrics. You manage a handful of KPIs. Promote a metric to a KPI only when moving it changes a real business outcome.

Watch for vanity metrics: numbers that look impressive but do not drive decisions. Total impressions or raw follower count often qualify. A metric earns its place when a change in it tells you to act.

How to Check Metrics

Find metrics in any analytics or ad platform, usually as the columns of a report.

  1. In GA4, open Reports and read the metric columns, or use the Explore section to drag metrics into the Values area.
  2. In ad platforms (Google Ads, Meta Ads), metrics appear as selectable columns like Clicks, CPC, and Conversions.
  3. For derived metrics, use a calculator. Run figures through linkutm’s free marketing calculators to compute CTR, ROAS, conversion rate, and more.

Always confirm the definition behind a metric. “Conversions” can mean different actions across tools, so check what each platform counts before comparing numbers.

Frequently Asked Questions

What is a metric in analytics?

A metric is a quantitative measurement expressed as a number, such as Sessions, Users, or Revenue. It counts or calculates activity rather than describing it. In a report, metrics are the values measured against a dimension like Country or Source.

What is the difference between a metric and a dimension?

A metric is a number you measure; a dimension is a category that groups it. Sessions and Conversions are metrics. Country and Device category are dimensions. If you can add it up, it is a metric. If it labels the total, it is a dimension.

What is the difference between a KPI and a metric?

A KPI is a metric tied to a business goal, while a metric is any number you can track. Every KPI is a metric, but most metrics are not KPIs. You measure many metrics but manage only a few KPIs that signal whether targets are met.

What are marketing metrics?

Marketing metrics are numbers that measure campaign, channel, and content performance. They span the funnel, from acquisition metrics like CTR and CPC to revenue metrics like ROAS and LTV. They show what is working and where budget is wasted.
