I am now a top rated seller and here are the secrets to quickly get started and rise to the top from my experience:
BE AVAILABLE FULL TIME - this is a challenging, coz a buyer can contact you in the middle of the night and since a buyer knows and needs the services on demand, and he/she doesn't understand that its night on your end considering the time zones. If you are not willing to wake up at the middle of the night to respond to your buyer, the you are far from it! Alternatively you can always turn on availability, but that will outweigh you comparing to someone who is available 24/7.
Quick Suggestions
Turn on Notifications, and on your phone give Fiverr specific unique notification sound different from all others.
Give Fiverr app Top Priority on your phone, PIN it on the desktop of your phone with direct access without scrolling.
Allow Fiverr app full battery usage, do not optimize the battery use.
With that you will always be available to your buyers and instant reply which the buyers like most.
So the startup is the AVAILABLITY.
Hope this helps someone. Thumps up is this make sense.
Thanks
