The conversion rate, also known as the conversion rate, is a key performance indicator (KPI) in the Online marketing. It describes the ratio of visitors to a website or a Marketing measure to the actual actions that these visitors perform and that were previously defined as a goal (conversions). The value is given as a percentage and measures how effectively a website or campaign converts visitors into desired actions.
A conversion is not just a purchase. It can include any defined target action that a user performs. This includes, for example, filling out a contact form, subscribing to a newsletter, downloading an e-book, registering or clicking on a specific call-to-action (CTA). These actions can be classified as micro-conversions (e.g. newsletter subscription) or macro-conversions (e.g. purchase completion), depending on their importance for the business objectives.
Calculation of the conversion rate
The conversion rate is calculated using a simple formula. It is calculated by dividing the number of conversions by the total number of visitors or interactions, multiplied by 100 to obtain a percentage value.
The formula is:Conversion rate = (number of conversions / number of visitors) × 100 %
A practical example illustrates this: If a Online store 10,000 visitors and 300 of them make a purchase, the conversion rate is calculated as follows: (300 conversions / 10,000 visitors) × 100 % = 3 %. It is important to take bots and repeated page views by the same user into account in the calculation in order to obtain the most accurate result possible.
Importance and optimization in online marketing
The conversion rate is a key performance indicator for evaluating the success of websites and Marketing campaigns. A high conversion rate indicates that a website or marketing measure is efficient by successfully moving visitors to desired actions. It enables companies to measure the ROI (return on investment) of their marketing activities and identify areas with optimization potential.
The targeted improvement of the conversion rate is called Conversion Rate Optimization (CRO) described. Factors influencing the conversion rate are diverse and include, among other things Website design, the user experience (UX), the relevance of the content, clear calls to action (CTAs), the Technical performance of the site, the product range and the exact target group approach. Through continuous analysis and targeted adjustments, such as A/B tests, the conversion rate can be significantly increased, which leads directly to more sales.
