Short answer: The marketing KPIs that matter most are the ones tied to revenue: customer acquisition cost (CAC), customer lifetime value (LTV) and the LTV:CAC ratio, conversion rate, marketing-sourced pipeline or revenue, return on ad spend (ROAS) and retention. Reach, followers and clicks are useful diagnostics, but they should not be the headline numbers in a marketing report.
Core KPIs and how to calculate them
| KPI | Formula | What it tells you |
|---|---|---|
| CAC | Sales and marketing cost ÷ new customers | What a customer costs to win |
| LTV | Average revenue per customer × gross margin × average lifetime | What a customer is worth |
| LTV:CAC | LTV ÷ CAC | Whether growth is profitable (3:1 is a common benchmark) |
| CAC payback | CAC ÷ monthly gross margin per customer | Months to earn back acquisition cost |
| Conversion rate | Conversions ÷ visitors or leads | How well each stage works |
| ROAS | Revenue from ads ÷ ad spend | Short-term paid media efficiency |
| Retention / churn | Customers kept ÷ customers at start of period | Whether customers stay |
| Marketing-sourced pipeline | Value of opportunities from marketing | B2B contribution to sales |
Supporting metrics by channel
- SEO: organic clicks and impressions (Search Console), rankings for priority queries, organic conversions.
- Social: reach, saves, shares, profile visits, traffic and conversions from social.
- Email: click rate, conversion rate, unsubscribes, revenue per email. Open rates are unreliable since Apple Mail Privacy Protection.
- Content: engaged time, assisted conversions, newsletter sign-ups.
How to set up a KPI report
- Pick three to five headline KPIs tied to business goals.
- Add channel metrics underneath as diagnostics.
- Show trends over time and against targets, not single numbers.
- Write one line per KPI explaining what changed and why.
GA4, Search Console and your CRM cover most needs; a dashboard in Looker Studio ties them together.
Common mistakes
- Reporting vanity metrics without context.
- Using last-click attribution only, which undervalues content and social.
- Changing definitions between reports.
Bottom line: Choose a few marketing KPIs tied to revenue and review them on a fixed rhythm. Too many marketing KPIs make it harder, not easier, to decide. Write down who owns each of your marketing KPIs and what action follows when one moves.
Frequently asked questions about marketing KPIs
What is a good LTV:CAC ratio?
Around 3:1 is the widely used benchmark; much higher may mean you are underinvesting in growth.
What is the difference between a KPI and a metric?
A KPI is a metric you have chosen as a key indicator of a goal; every KPI is a metric, but not every metric is a KPI.
