How can i get fiverr badgges
Do you mean Forum badges? @imagination7413 has a handy dandy link to give you info about that.
Sure! Here: https://forum.fiverr.com/badges
Each badge tells you the conditions to earn it.
If you meant profile badges: https://sellers.fiverr.com/en/article/learn-from-fiverr-and-skill-tests
These can only be gotten if you complete a Fiverr Learn course. (There is one free one available.)
