The vanity metrics quietly draining your budget

A vanity metric is any number that goes up while your bank account does not. They are seductive because they almost always move in the right direction, and because platforms are happy to show them to you.

The usual suspects

• Impressions and reach. Easy to inflate, hard to connect to revenue.
• Platform-reported ROAS. Every channel claims the same conversion. Add them up and you have "sold" each order three times.
• Engagement rate. A like is not a euro.
• Click-through rate in isolation. A high CTR on traffic that never buys is a faster way to lose money.

A simple filter

Before a metric earns a place on your dashboard, ask one question:

If this number doubled tomorrow, would we make more money, and could we prove it?

If the answer is no, or "probably," it is a vanity metric. Demote it.

What to track instead

• Contribution margin after ad spend.
• Blended ROAS across all channels, not per-platform.
• New-customer cost vs. repeat revenue.
• Payback period.

None of these are as flattering as a six-figure reach number. All of them tell you whether the business is actually growing. That is the trade you want to make.
