i dont have any proof of this. but this what i have learnt during my 3-4 years on fiverr… fiverr’s algorithm automatically removes the best performing gigs from the top sometimes to give new sellers a chance. everyone should get a chance. this happens to me like every 3 months. when it does i edit my, do more research and make it better. up to you 🙂 you can always improve your gigs.
