The Paid Social Metrics That Actually Matter (And the Ones You Can Ignore)
Walk into any marketing meeting and you’ll hear people talking about ROAS, CPM, reach, engagement rate, impressions… the list goes on. Most of it doesn’t matter as much as people think.
Data is only useful if it’s connected to a decision. And most of the metrics DTC brands obsess over aren’t driving better decisions — they’re just filling up the report.
Here’s the breakdown of what to actually track, what to check occasionally, and what to stop looking at altogether.
Metrics That Actually Drive Decisions
Cost Per Acquisition (CPA) / Cost Per New Customer
This is the one that matters most. How much are you paying to acquire a customer? This needs to be viewed in the context of your average order value and customer lifetime value — not in isolation. A £50 CPA might be fine for a £150 AOV product. It might be catastrophic for a £30 one.
New Customer Acquisition vs Returning Customer Revenue
Platform-reported ROAS often mixes up revenue from brand new customers and revenue from people who would have bought anyway. Separating these is essential. Paid social’s primary job is usually to bring in new customers — so that’s what you should be measuring.
Hook Rate and Hold Rate (for Video Ads)
Hook rate is the percentage of people who watch past the first 3 seconds. Hold rate measures how long they stay. These two metrics tell you more about creative quality than any other number. A high hook rate with a low hold rate means your opening is strong but the ad loses people. Low hook rate means you’re losing them before they’ve even started.
Click-Through Rate (CTR) by Placement
CTR tells you whether your creative and copy are compelling enough to make someone act. But it needs to be read by placement — a 0.5% CTR might be strong for Facebook Feed and weak for Stories. Context matters.
Metrics Worth Checking, Not Obsessing Over
ROAS (Return on Ad Spend)
Yes, really. ROAS is useful as a directional signal, but it’s not the complete picture. It’s affected by attribution windows, platform discrepancies, and it doesn’t account for margin. Use it as a gut-check, not a gospel.
CPM (Cost Per 1,000 Impressions)
CPM tells you how expensive it is to reach people. It’s worth watching because a sudden spike in CPM can explain a drop in performance. But a low CPM isn’t inherently good — cheap impressions to the wrong audience is still wasted money.
Frequency
High frequency (seeing the same ad many times) can indicate creative fatigue in retargeting campaigns. Worth monitoring, but don’t panic at a frequency of 3 or 4 — panic when performance starts dropping alongside it.
Metrics You Can Stop Worrying About
Reach and Impressions
These are vanity metrics for paid social. A DTC brand doesn’t benefit from being seen by a lot of people who don’t buy. Unless you’re running a pure brand awareness play, reach is mostly noise.
Engagement Rate on Ads
Likes and comments on ads feel nice. They don’t pay the bills. Some of the best-performing DTC ads have very little engagement. Some heavily liked ads convert terribly. Stop equating engagement with effectiveness.
Page Likes and Follower Growth From Ads
In 2026, running paid ads to grow your follower count is almost never worth it. The organic reach just isn’t there to justify it. Followers from ads rarely become buyers.
The Framework That Actually Works
Good paid social reporting answers three questions: Are we acquiring customers profitably? Is our creative working? What are we testing next?
If your reporting answers those three questions clearly, you’re ahead of most brands. If it’s 20 slides of platform-reported metrics that no one really understands — you might need a new approach.
This is exactly the kind of clarity we build for the brands we work with. If you want a reporting setup that actually helps you make decisions, get in touch.
