What is a KPI? (Key Performance Indicator)
The term KPI stands for Key Performance Indicator, which is translated into French as key performance indicator. A KPI is therefore a numerical indicator, selected because it directly reflects the performance of an action, a service or a strategy in relation to a measurable objective.
If you are looking for a simple KPI definition: a KPI is a figure that tells you, at a glance, whether you are ahead, on target or behind what you want to achieve (number of sales, turnover, leads generated, conversion rate, acquisition cost, customer satisfaction, etc.).
Not all indicators are KPIs: a KPI is a priority metric that really helps with decision-making, where other data are only contextual statistics.
KPI, indicator and objective: making a difference
In everyday language, we often confuse KPI, indicator and objective, even though they are complementary but different concepts.
- The objective describes what you want to achieve. Example: increase turnover by 20% in 12 months.
- The indicator is a numerical measurement which describes a reality. Example: monthly turnover, gross margin, number of orders or traffic on a site.
- The KPI is the key indicator that you choose to measure the achievement of a strategic objective.
In other words: all KPIs are indicators, but not all indicators are KPIs. A good KPI is directly linked to the success of an action or strategy.
Why are KPIs essential for your business?
key performance indicators play a central role in managing a business and in digital marketing.
- Align teams: clear KPIs give everyone the same definition of success.
- Monitor performance: dashboards and reports allow you to quickly detect changes.
- Make data-driven decisions: choices are driven by numbers rather than intuition.
- Measure return on investment: KPIs allow you to evaluate the effectiveness of a marketing campaign or commercial action.
Without KPIs, it becomes difficult to know whether a strategy is actually working or whether the results are simply related to external factors.
How to choose the right KPIs?
Choosing the right KPIs is often more important than tracking a lot of them. A few principles make it possible to select truly useful indicators.
The SMART method
KPIs should ideally follow the SMART method.
- Specific: it measures a specific aspect of performance.
- Measurable: it can be expressed as a number or percentage.
- Achievable: the associated objective is ambitious but realistic.
- Realistic: it takes into account the context and available resources.
- Temporal: it is linked to a defined period.
Limit the number of KPIs
Following too many indicators makes decision-making more difficult. In most cases, tracking between three and seven main KPIs is enough to effectively manage an activity.
The objective is to focus on the indicators that really influence growth, conversion, loyalty or profitability.
Examples of marketing, sales and financial KPIs
To illustrate the definition of a KPI, here are some examples commonly used in businesses.
Marketing KPIs
- Number of leads generated.
- Visitor to lead or lead to customer conversion rate.
- Cost per lead or customer acquisition cost.
- Email open rate and click-through rate.
- Share of organic traffic in overall traffic.
Commercial KPIs
- Monthly turnover.
- Rate of conversion of quotes into orders.
- Average basket.
- Number of opportunities in the commercial pipeline.
- Average sales cycle length.
Financial KPIs
- Gross margin or net margin.
- Operating profit or EBITDA.
- Operating cash flow.
- Customer acquisition cost compared to customer lifetime value.
- Churn rate in a subscription model.
Each sector has its own business KPIs, but the principle remains the same: follow indicators that directly reflect value creation.
Digital KPIs: web analytics, SEO and acquisition
In digital marketing, KPIs make it possible to analyze the performance of a website, an SEO strategy or advertising campaigns.
KPIs related to the website
- Number of sessions or unique users.
- Bounce rate and average session duration.
- Number of pages viewed per visit.
- Conversion rate of a form or purchase.
- Mobile performance compared to desktop.
SEO KPIs
- Organic traffic from search engines.
- Average position on strategic keywords.
- Number of pages positioned in the Top 10.
- Organic click-through rate in search results.
- Leads or sales generated by SEO.
Paid acquisition and social media KPIs
- Cost per click and cost per acquisition.
- Return on advertising spend (ROAS).
- Engagement rate on social networks.
- Community growth.
- Conversions assisted by the different channels.
The main thing is not to follow all these indicators, but to choose the ones that really correspond to your strategy and your business model.
Common errors with KPIs
Confusing KPI and vanity metrics
Some metrics may seem impressive but don't really help with the decision, such as the number of likes or views. If these numbers are not linked to conversions or sales, they are not strategic KPIs.
Following too many indicators
Multiplying KPIs dilutes attention and complicates decision-making. It is better to focus on a few truly strategic indicators.
Do not link KPIs to actions
A KPI must be actionable. If an indicator drops or increases sharply, it must trigger an analysis and possibly a decision.
Never revise your KPIs
KPIs must evolve with the company’s strategy. An indicator relevant to the launch of a project may become less important once the activity matures.
