Badges rarity can be a bit tricky to understand but it’s a great tool to incentivise customers to hunt for badges.
How rarity works
Firstly, the system calculates what percentage of your users actually owns the badge using this simple rule :
Percentage = Number of users owning the badge x 100 / Number of registered users on the website
This rule gives a number between 0 and 100.
Secondly, the system compares the calculated percentage to the different rarity levels. And it retains the level that matches these rules :
- The rarity level number must be higher than the percentage
- The rarity level number must be the closest to the percentage of the rarity levels matching the precedent rule.
For example, let’s take a badge owned by 35% of users. We have the following rarity levels :
- 20 – Rare
- 50 – Uncommon
- 100 – Common
If we apply the rules explained above, we get this result :
- The rarity level number must be higher than the percentage : Only the common and uncommon levels match that rule
- The rarity level number must be the closest to the percentage : The uncommon level is the closest to the percentage
In our example, the badge’s rarity is : Uncommon
Edit rarity levels
To edit the different rarity levels, go to Badges → Settings
As you can see, there are some default rarity levels already set. If you want to edit one, simply click on the quick edit button on the line.
When you add or remove rarity levels, reload the page to see them sorted by percentage.
