How is the overall assessment score calculated?

Written by Robin Hulskers

Rating


The rating shows at a glance how customers rate your online store. This rating is based on the stars that customers give when leaving a review. You can see the rating in our widget, in the sidebar, and on your member profile, among other places. Because this is often the first thing visitors notice, it plays an important role in the first impression of your online store. Below, we explain how this rating is calculated.


Voorbeeld beoordeling sterren naar cijfer


From stars to numbers


We use a scale of 1 to 5 stars. We convert these to a rating between 2 and 10 using a fixed calculation method. For example, a 3-star rating corresponds to a 6. One star therefore does not result in a 1 or 0, but a 2.


Your average score is calculated by giving all reviews equal weight and taking the average.


Ook de score uit externe review platformen telt mee voor jouw gemiddelde


Reviews from external platforms


In addition to reviews posted via WebwinkelKeur, you can also display reviews from external review platforms. These reviews count fully towards your average score.


For example, if you have 100 reviews on WebwinkelKeur with an average of 9 and 100 reviews on another platform with an average of 8, your total average will be 8.5.


What effect does a new review have on my score?


We are often asked why one negative review can immediately lower your score, while a positive review sometimes has little effect. This happens especially when you already have a high average score. A positive review is then close to your current average, while a negative review deviates significantly from it.


An example will clarify this.


Suppose you have an average score of 9.7 based on 90 reviews. You receive a new 5-star review, which corresponds to a 10. The new calculation is then:



  • ((9.7 × 90) + 10) / 91 = 9.703


Your average remains rounded to 9.7.


If, instead, you receive a 1-star review, which corresponds to a 2, the calculation becomes:



  • ((9.7 × 90) + 2) / 91 = 9.615


Your average now drops to 9.6. This is because this rating is further away from your existing high average.
