Most dashboards measure effort and call it evidence.
Impressions, reach, followers, posts published, emails sent. All easy to collect, all responsive to working harder, and none of them tell you whether the business is better off.
The useful numbers are fewer and less flattering.
The five that matter
1. Cost to acquire a customer
Everything spent on marketing and sales, divided by customers acquired. Not cost per lead, not cost per click — per actual customer. This is the number that determines whether growth is a business or a hobby.
2. What a customer is worth
Average order value, purchase frequency, and how long they stay. Without this, the acquisition number is meaningless, because you cannot know what you can afford to pay.
3. The ratio between them
Lifetime value divided by acquisition cost. Under 3:1 is usually a warning. Over 5:1 often means you are under-investing and leaving growth on the table.
4. Payback period
How many months until an acquired customer has repaid what it cost to acquire them. This is the number that determines how fast you can grow without running out of cash, and almost nobody tracks it.
5. Repeat rate
The share of customers who buy again. The cheapest growth available to any business, and the first thing that quietly deteriorates when marketing chases new customers exclusively.
The ones to stop reporting
- Impressions and reach. A measure of what you bought, not what happened.
- Follower growth. Decoupled from outcomes on every major platform.
- Engagement rate, in isolation. High engagement on content that reaches nobody relevant is not a result.
- Website traffic, without conversion context. More visitors to a page that does not convert is a more expensive way to fail.
- Email open rate. Increasingly unreliable and never a business outcome.
These are diagnostic, not evaluative. Useful for explaining why something moved. Useless as the headline.
Attribution: be honest about it
Attribution is directionally useful and precisely wrong, always. Cross-device journeys, blocked tracking, offline conversions, and the simple fact that people are influenced by things they never click all guarantee it.
Practical approach:
- Use platform data for optimization, not for truth. It is good at telling you which ad beat which ad.
- Use total revenue against total spend for truth. Blunt, unglamorous, and much harder to fool.
- Ask customers how they found you. A one-field question at checkout produces information no analytics tool can.
- Run holdouts. Turn something off in one market for a month. Uncomfortable, and the only real proof of incrementality available to most businesses.
The reporting rhythm that works
- Weekly: spend, results, cost per result. Fifteen minutes. Catches things breaking.
- Monthly: the five numbers above, with a written explanation of what changed and what you are doing about it.
- Quarterly: the honest question — is this channel still worth what we are putting into it?
A dashboard nobody interprets is not reporting. The interpretation is the product.
The bottom line
Track acquisition cost, customer value, the ratio, payback, and repeat rate. Treat everything else as diagnostics. And accept that attribution is a compass rather than a map — the businesses that grow are the ones comfortable making decisions on directional evidence.
