What is a KPI (Key Performance Indicator)?
KPI stands for Key Performance Indicator and works as a key metric that measures how well you're meeting your business goals. You can think of KPIs as a kind of compass that shows whether you're heading in the right direction and whether your efforts are having the desired effect. A KPI is always based on numbers, but that doesn't necessarily mean it's only about finances — it could just as easily be about customer satisfaction, lead quality or employee engagement.
The point of working with KPIs is to create a shared understanding of what success means for the business. When you link your KPIs to specific objectives in the strategy, you can measure and document progress across areas such as marketing, operations and sales. Put simply, KPIs show how your activities actually affect the company's bottom line – for example, when you measure the return on an SEO effort or the impact of your ads on social media.
KPIs differ from ordinary data or metrics because they're linked directly to the company's strategic goals. In other words, they're not just numbers, but numbers that matter and that enable you to steer towards a desired result.
How do you use KPIs?
When you work with KPIs, you start by defining your business goals. Only once you know what you want to achieve can you choose the metrics that best reflect progress. You then set precise measuring points that you track over time. This makes your results comparable and creates an objective basis for decisions.
In practice, you use KPIs to evaluate the results of your initiatives. If you work with SEO, for example, a relevant KPI could be organic traffic or the conversion rate from Google. In social media marketing, you can use engagement rate or follower growth as indicators of whether your strategy is reaching the target audience. By comparing your KPIs with the planned goals, you can quickly see what's working and what needs adjusting.
You can anchor your KPIs in a broader business context by distinguishing between strategic and operational KPIs. Strategic KPIs show whether you're moving towards the company's overall goals, while operational KPIs are about day-to-day performance – e.g. response times, campaign results or customer satisfaction at specific touchpoints.
Why are KPIs important?
Without KPIs, it's hard to judge whether your activities actually make a difference. KPIs make it clear which initiatives create value and which don't. You get both a measure of success and an early warning when something isn't going to plan. That makes it possible to act quickly and prevent bigger problems.
A well-defined set of KPIs ensures that everyone in the organisation works towards the same goals. It provides a common language for performance, so each department can see how its efforts contribute to the whole. In marketing, for example, it's crucial that the KPIs in Google Ads match the goals of the overall brand strategy. That way, all channels pull in the same direction and strengthen each other's impact.
KPIs also support your decision-making. When you base your choices on data instead of gut feeling, you can prioritise the initiatives that deliver the greatest return. That makes the KPI an important tool in optimisation work – both at campaign level and in the long-term strategy.
What types and variants are there?
Broadly speaking, there are two types of KPIs: high-level and low-level. High-level KPIs measure the company's overall performance at a strategic level. These could be parameters such as revenue, market share or customer satisfaction. These metrics give an overview of how the company is performing as a whole.
Low-level KPIs, on the other hand, measure at tactical or operational levels – often within individual departments. This could be CTR (Click-Through Rate) in a Google Ads campaign, open rate in e-mail marketing or response time to customer enquiries. They support day-to-day decisions and help you assess whether your short-term efforts point towards the long-term goal.
An important point is that high-level and low-level KPIs must be connected. When you anchor your operational metrics in the overall strategy, you create a golden thread from the individual activity to the company's main goals.
How do you work with KPIs in practice?
The most effective starting point for KPI work is the SMART model. SMART stands for specific, measurable, achievable, relevant and time-bound. The model ensures that you set goals that are realistic and concrete enough to be measured. That makes it much easier to adjust your efforts along the way.
Example of how to set a digital KPI:
Working with KPIs isn't just about measuring – it's also about responding. You need to continuously compare the results with your goals, analyse the reasons behind any deviations and adjust the strategy. That applies whether you're optimising ads in Google Ads, updating your content based on SEO data or fine-tuning the messages in your social campaigns.
You get the most out of KPIs when you gather all the data points in regular reports or dashboards. This gives you a continuous overview of performance and helps you prioritise efforts where they have the most impact.
What should you watch out for?
A KPI only adds value if it's relevant and understood by the people working with it. You should therefore choose indicators that employees can relate to and that are genuinely affected by their efforts. Otherwise, the numbers no longer help you steer. You should also avoid having too many KPIs, because it dilutes focus. Better to have a few precise measuring points that reflect the most important goals.
Another pitfall is choosing KPIs that only measure results, not processes. It's often in the processes that you find the reasons behind the results. That's why you should combine output KPIs, such as sales figures, with input KPIs, such as the number of qualified leads or production speed. That way, you get a picture of both where you are and why you're there.
Finally, it's important to remember that KPIs aren't static. Markets change, strategies evolve and new channels emerge. Your KPIs therefore need to be reviewed regularly so they reflect the company's current direction. When you make this a fixed part of your strategic work, the KPI becomes a living management tool — not just a number on a dashboard.
