I mean promote your gig here, on Fiverr. I don't know if this option is available for everyone though.

You pay only for clicks, so it's worth trying in my opinion.

I started on Fiverr three years ago, and I remember that my prices were very low back then (I think starting from $5). It was a bit hard for me because I was already quite an experienced designer, and $5 in my country doesn't even get you a coffee. However, I was waiting for this snowball effect, and it eventually happened.
I received my first order after around three months. I tried changing my gig descriptions, keywords, and reducing the number of gigs.
When I look at your profile, it looks really nice. Your descriptions are great, and the quality of your work is lovely. You just need to experience this snowball effect.
Have you considered trying a Seller Premium program?
