Most marketing dashboards are full of numbers that go up and to the right while the bank balance doesn't move. If you only track five things, track these — they tell you whether your marketing is actually building a business.
1. Customer acquisition cost (CAC)
What it costs, all-in, to win one customer. Add up everything you spent on marketing and sales in a period, divide by the customers you got. If you don't know this number, you don't know whether you're buying growth or buying losses.
2. Lifetime value (LTV)
What an average customer is worth to you over the whole relationship, not just the first sale. The figure that matters is the ratio of LTV to CAC. A healthy business earns back several times what it spends to acquire a customer. If LTV barely covers CAC, no amount of extra ad spend fixes it.
3. Return on ad spend (ROAS)
For every unit of currency you put into ads, how much comes back in revenue? It's the fastest read on whether a paid channel is pulling its weight — but treat it as a steering wheel, not a trophy. A high ROAS on tiny spend isn't a business; the goal is strong returns as you scale.
4. Conversion rate
The percentage of people who take the action you want — enquire, buy, book. It's the multiplier on everything else: double your conversion rate and you've effectively halved your cost of every lead without spending a cent more on traffic. It's almost always cheaper to improve than to buy your way around.
5. Payback period
How long it takes to earn back what you spent to acquire a customer. The shorter it is, the faster you can reinvest and the less cash you need to grow. For a young business especially, a quick payback period is often more important than a big LTV that arrives years from now.
What to stop watching
Impressions, reach, follower count and likes on their own. They're not worthless — they're just inputs, not outcomes. They only matter if they eventually move one of the five numbers above. If a metric can go up while your revenue stays flat, it doesn't belong at the top of your report.
