Marketing KPIs That Actually Matter + Vanity Metrics You Can Ignore

Written by Jordan Van Ahn | April 10, 2025 8:31:36 PM Z

Let’s be honest: sometimes, your marketing dashboard feels more like a highlight reel than a true picture of performance. The charts look great. The numbers are up. But… something still feels off.

And yes — even AI can mislead you.

Not because it’s wrong, but because it’s doing exactly what you told it to do. If the prompt is fuzzy, if your goals aren’t clear, or if you're chasing metrics that look good but don’t mean much, AI will happily optimize toward the wrong outcomes. Fast.

The truth is, AI is incredibly powerful — but it's only as good as your structure, your follow-through, your understanding of your industry, and most importantly, your clarity around what success actually looks like. If you don’t define that, AI can’t help you get there. It’ll just make you feel productive.

That’s why this post is important. We’re going to cut through the noise and:

  • Clarify the difference between meaningful KPIs and vanity metrics

  • Explore why we often chase the wrong numbers

  • Highlight which metrics truly move the needle in a business

  • And put it all in the context of how AI fits into this new landscape

What Are Vanity Metrics?

Vanity metrics are those flashy, feel-good numbers that look impressive but rarely tie back to business outcomes.

Think:

  • Pageviews

  • Social media followers

  • Likes and impressions

  • Email open rates (with no click or action)

  • Keyword rankings

Sure, these stats can signal attention or early interest, but they’re not KPIs unless they directly influence revenue, customer retention, or profitability.

Why We Fall for Vanity Metrics

  1. They’re everywhere. Most platforms showcase them by default.

  2. They feel rewarding. Big numbers = dopamine.

  3. They’re easier to report. It’s more comfortable to share a win than explain a challenge.

  4. They’re rarely challenged. They make us feel like we’re moving forward, even when we’re spinning in place.

But without context and alignment to business outcomes, they’re just noise.

KPIs That Actually Matter (And Why)

Let’s shift focus. These are the metrics worth tracking — the ones that truly support growth.

1. Customer Acquisition Cost (CAC)

  • Tells you how much it costs to acquire a customer. If it’s too high, your model may not be sustainable.

  • Tip: Break it down by channel or campaign.

2. Customer Lifetime Value (LTV)

  • Tells you how much a customer is worth over time.

  • High LTV allows more flexibility with CAC.

3. LTV:CAC Ratio

  • A great at-a-glance indicator of business health. 3:1 or better is the general benchmark.

4. Conversion Rate (CR)

  • Tracks the % of users who move from one funnel stage to another.

  • Always look at the full funnel, not just the end.

5. Return on Ad Spend (ROAS)

  • Revenue generated per dollar spent. Combine it with profit margin for a clearer picture.

6. Marketing Efficiency Ratio (MER)

  • Total revenue / total marketing spend. A broader metric than ROAS, especially useful for brand-led growth.

7. Churn Rate (for SaaS or subscriptions)

  • Shows how quickly customers are leaving. Lower is better — and solving it boosts LTV.

8. Sales-Qualified Leads (SQLs)

  • Tracks high-quality leads who are ready to buy. Focus on quality over quantity.

9. Revenue Attributed to Marketing

  • Directly ties your campaigns to sales outcomes.

  • Attribution isn’t perfect, but directional data is better than none.

10. Net Promoter Score (NPS)

  • Measures how likely customers are to refer you. Loyalty is a leading indicator of growth.

Context Still Matters

Even the best KPIs can lead you astray if taken out of context.

A 4x ROAS sounds great — until you realize your profit margins are razor-thin. A 60% open rate is exciting — until you find no one clicked.

Ask yourself:

  • Is this metric tied to a real business outcome?

  • Does it inform better decisions?

  • Is it something I can take action on?

If not, reconsider how much weight you give it.

So Where Does AI Fit In?

Here’s where things get exciting — and a little dangerous. AI can:

  • Forecast LTV based on behavior patterns

  • Recommend audience segments based on CRM data

  • Write copy that’s conversion-optimized

  • Auto-bid and optimize campaigns in real-time

But here’s the thing: AI still needs a driver. It needs you to decide what success means. If your inputs are based on emotion, or if you're measuring the wrong thing, AI will take you further down the wrong path.

In other words: AI doesn’t remove the need for critical thinking — it multiplies the importance of it.

How to Align KPIs With Business Goals

  1. Get clear on what success means. Revenue? Retention? Market share?

  2. Map your funnel or customer journey. See where marketing plays a role.

  3. Select 3–5 key KPIs that reflect business outcomes.

  4. Use AI or tools to track, not decide. Let insights guide you, not rule you.

  5. Review monthly, not just weekly. Trends beat one-off spikes.

Final Thoughts

Vanity metrics have their place — they can indicate reach or spark ideas. But if you're serious about growth, they can’t be your compass.

Real marketing KPIs aren’t just about tracking. They’re about clarity. They help you lead teams, guide AI tools, and make confident decisions that move your business forward.

So go ahead and look at the likes. Smile at the impressions. But base your strategy — and your success — on the numbers that matter.

And remember: your tools are only as good as your thinking.
