You may already know about it, if you do then move on!! If you type fiverr DOT com/users/YOUR USER NAME GOES HERE/manage_orders It will show you all of the people that have given you feedback and the ones who have not. Now you can send a message to the ones who have not given you feedback and offer them some sort of incentive in return for good feedback. ALSO (Random Tip) What I do is change my gig completion time to 29 days and then buy 5 gigs from myself from one of my other accounts. And then change the completion time back to 1 day (or however long it takes for you to complete your gig) So now when someone checks out your gig it says that you have 5 orders in the queue this gives the illusion that your gig is on fire.
