The deck opens with a slide showing follower growth: up 40% year-on-year. The next slide: reach, up 60%. Impressions, up 80%. The room nods. Someone says “great numbers.” The CMO asks a question about awareness. Everyone is pleased.
Nobody asks how many of those followers bought anything, changed their behavior, or can recall the brand name 48 hours later. The meeting concludes. The agency retains the account.
What Makes a Metric Vanity
A vanity metric is one that can increase while the business declines, stays flat, or suffers. Follower counts are the canonical example: a brand can gain 50,000 followers in a month through a giveaway campaign or paid social amplification while its conversion rate falls, its customer retention worsens, and its net promoter score deteriorates. The vanity metric goes up. The business goes sideways or down.
Impressions are worse. An impression means the content appeared on a screen. It does not mean anyone read it, processed it, or experienced anything other than the passive stimulus of pixels in a field of vision. Impressions are a lower unit of attention than a blink.
Why Organizations Love Them Anyway
Vanity metrics solve a specific organizational problem: they’re easy to report, always go up (if the agency is doing its job), and provide a defensible number to attach to marketing spend without requiring any honest reckoning with whether that spend worked.
This is not entirely cynical. Brand awareness does matter. The problem is that impressions don’t measure awareness — they measure distribution. Reach doesn’t measure attention — it measures potential exposure. The proxy metrics have become so accepted as a substitute for the actual metrics that the substitution has become invisible.
The KPI Shark was born out of exactly this dynamic. If you’ve ever sat in a meeting watching someone present a dashboard of metrics that are going up while the business is going sideways, you’ll recognize the specific frustration it addresses.
The Metrics That Actually Tell You Something
Conversion rate (did people do the thing you wanted them to do), customer acquisition cost (what did it cost to get each new customer through this channel), retention rate (are people coming back), and share of voice in conversations that actually convert — these are uncomfortable metrics because they can go down, require longer attribution windows, and make it harder to hide poor performance behind impressive-sounding numbers.
Report them anyway. The brands that win over time are the ones whose internal conversations are about what’s actually happening, not what looks good in the deck.
