Are Your Meta Metrics Lying to You?

If you're obsessively watching ROAS on Meta, this one's for you. Because let's be honest, Meta's dashboard doesn't always tell the full story. Some metrics are pure gold, others are fool's gold. Here's your no-fluff guide to what really matters, what you can ignore, and how to set up reporting that actually helps you make money.

Why Meta's Default Metrics Can Mislead You

If Meta Ads Manager is your only guide, you're not getting the full picture:

• Attribution issues: with privacy changes and shortened windows, you might be underreporting results

• ROAS isn't profit: a 4x ROAS sounds great until you realise your cost of goods and shipping eat up most of it

• Laggy metrics: sometimes purchases take a few days to show up, especially with delayed reporting or attribution mismatches

Metrics That Actually Matter in 2025

1. Cost per Purchase

Still the holy grail for eComm. But don't take it at face value, compare it to your AOV and profit margins.

2. MER (Marketing Efficiency Ratio)

Your total revenue divided by your total marketing spend. If your Meta ads look great but your MER is 2x, you might be spending too much elsewhere or not converting enough.

3. CAC (Customer Acquisition Cost)

This goes beyond Meta. Total marketing cost divided by new customers acquired. Keep an eye on it monthly.

4. Landing Page Views vs View Content

If your View Content number is way higher than your Landing Page Views, you have a pixel or website issue. This is an underrated diagnostic tool.

5. Returning Customer Rate

Pull this from your eComm platform or GA4. It tells you if people love you enough to come back and helps you calculate LTV.

Metrics You Can Chill About

• CPM (Cost per 1,000 Impressions): only worry if it's absurdly high. Otherwise, focus on results

• CTR (Click-Through Rate): nice to have, but doesn't pay the bills. A high CTR with no purchases? Not helpful

• Page Likes, Post Comments: vanity metrics. Fun for the ego, irrelevant for your bottom line

How to Build a Real Reporting Dashboard

You don't need fancy tools to get started. Here's what to track:

• Start with the Performance & Clicks preset

• Then customise and add: Landing Page Views, Content Views, Add to Cart, Initiate Checkout, Purchases (total, value, cost, and ROAS)

• Go through and untick everything else for a cleaner dashboard
