People with an affinity for numbers like everything that can be measured. KPIs or key performance indicators are then developed from the results. These enable the comparison of the campaign or individual motifs. This replaces the "gut feeling" with hard numbers. In particular, the results of A/B testing can be compared precisely in this way.

But what do all the key figures mean? We would like to give you a little help here and compare the different key figures. Not every indicator makes sense for everyone or every company. For example, a conversion rate for an online shop is something different than for a normal website.
