Marketing Metrics That Matter: What to Track and What to Ignore

By Gabriel de Freitas Carvalho · 2026-09-29

More data doesn't mean better decisions. A small set of metrics, reviewed consistently, is enough to run marketing well.

Metrics worth tracking

Metrics that can mislead

Followers, likes and impressions show reach, not business results. They can be useful context, but a post with thousands of views and no enquiries did not generate leads. Always connect activity to a lead or sale.

A simple rule

If LTV is well above CAC and your conversion rate is stable, you can spend more to grow. If CAC is close to or above LTV, fix the offer, follow-up or targeting before scaling.

How often to review

Look at leads and cost weekly, conversion and CAC monthly, and LTV quarterly. Write down the decision each review leads to; otherwise the numbers are just decoration.
