I am at a loss. Your gigs look good, your profile looks good.
There are some who will commiserate with you, saying, “Fiverr has been dead lately,” etc. It’s not. I’m covered up with work, and so are many others.
First, try to find yourself in the search. Perhaps by some error, you have been omitted, and a message to customer service could perhaps rectify this.
Second, add another gig. New gigs get extra exposure. Delete the 2 which have never been rated and created new ones. You’ve got to keep experimenting until something works.
Last, try to get out of that very crowded space you’re in. I read that there is a guy on here that does Danish-English translations. I thought, “There’s only like a thousand Danish people in the world. That won’t sell.” Well, evidently all thousand of them have hired a guy on Fiverr to do translations for them, because there are over a thousand reviews on just a single Danish-English translation gig. It’s still possible to find a (relatively) uncrowded corner of Fiverrworld where you’ll stand out better.
The only thing I know I wouldn’t do is nothing. It’s not working.
Best of luck to you,
