OKRs, KPIs and Benchmarks: What's the Difference and Why It Matters

​We’ve all been there. You're planning a campaign or reviewing quarterly progress, and terms like KPI, benchmark, and OKR are often used interchangeably. Add in the occasional 'vanity metric' or talk of industry standards, and it’s no wonder that clients, teams and stakeholders end up talking at cross purposes.

So let’s straighten things out. This post will take a closer look at what these different measurement tools mean, how they work together, and why understanding the distinction is key to making better decisions.

And yes, we’ll also tackle the role of vanity metrics and the unsung heroes of measurement: hygiene checks.

Start with Strategy: OKRs

Objective and Key Results (OKRs)

Objective and Key Results (OKRs) help you define what you want to achieve and how you’ll know when you've achieved it. They sit at a strategic level, providing a directional anchor for your team or organisation.

• Objective: A clear, ambitious goal
• Key Results: A handful of measurable outcomes that define success

For example:
Objective: Strengthen client retention
Key Results: Reduce churn rate by 15%, increase renewal rate to 80%, improve NPS score to 45+
OKRs are not the day-to-day metrics — they’re the destination you’re aiming for. If your BHAG is your North Star, your OKRs are the navigation markers.

Track the Journey: KPIs

​Key Performance Indicators (KPIs)

​Key Performance Indicators (KPIs) are the tools on your dashboard. They help you check whether you’re making progress. They’re operational, usually short-to-mid term, and tightly aligned to specific areas of your business.
Examples:

• Email open rate
• Lead-to-MQL conversion rate
• Cost per acquisition
• Customer lifetime value

But a common mistake is to label any metric as a KPI. In reality, only those that directly tie to your objectives should be classed as such. Otherwise, you’re just looking at numbers for numbers’ sake.

Get Some Perspective: Benchmarks

​Benchmarks help you understand what 'good' looks like. They give context to your KPIs, especially when clients ask, “Is that a normal result?”

Say your email campaign gets a 2.6% click-through rate. Without a benchmark, that means very little. But if the industry average is 2.1%, you know you’re outperforming. Equally, if your unsubscribe rate is 0.4% against a benchmark of 0.2%, it’s time to ask why.
​
Benchmarks are often drawn from industry studies, competitor analysis or past internal performance. They help you set targets that are both stretching and grounded in reality.

Don’t Overlook the Basics: Hygiene Metrics

​These rarely get the spotlight, but they matter more than many realise. Think of them as the health checks that keep your channels functioning.
In email marketing, these include:

• Bounce rate: Too high and you’ll start getting blocked
• Unsubscribe rate: A steady trickle is normal; a spike signals a mismatch in content or frequency
• Spam complaints: Damaging to sender reputation and email deliverability

​
They don’t tell you if a campaign worked — they tell you whether it’s safe to keep sending at all.

Ignore at Your Peril: Vanity Metrics

It’s tempting to shout about big follower counts, page impressions, or total reach.

​But these vanity metrics can give a false sense of success if they don’t tie to your objectives.
Ask:

• Do they influence behaviour?
• Can they drive revenue?
• Do they reflect progress towards our goal?

​
If not, they belong on a slide titled “Nice to See, Not to Act On.”

Bringing It All Together

Let’s look at a practical campaign to put it into context:
Scenario: You're running a re-engagement email campaign.

• OKR: Reconnect with dormant customers and drive renewed purchases
• KPIs: Open rate, click-through rate, MQLs generated, conversion rate
• Benchmarks: Industry click-through rate of 2.5%, unsubscribe threshold of 0.3%
• Hygiene metrics: Bounce rate, spam complaints, list decay
• Vanity metric: Total opens (interesting but not necessarily useful)

​
By naming each for what it is, you're better equipped to make data-led decisions — not just report numbers for the sake of it.

Final Thoughts

​Understanding the difference between OKRs, KPIs and benchmarks isn't just a matter of semantics. It’s about clarity. Clear thinking leads to better planning. Better planning leads to more relevant measurement. And that, in turn, leads to better results.

Throw in the quiet diligence of hygiene metrics and the healthy scepticism needed to filter out vanity stats, and you’ve got yourself a far more useful approach to performance measurement.
You might not need to use all five in every report, but knowing which is which means you’ll be a whole lot closer to hitting your targets.
