Review your gig description
If you don’t know how to write an engaging gig description then hire someone from Fiverr to write it for you. Right now your gig description doesn’t really explain why buyers should hire YOU and not someone else. Stating that logos are important doesn’t really help you.
Create more gigs and group your logos by style
For example, group 3D logos under one gig, sport related logos under a different gig etc. That way you can optimize each gig for a specific style and buyers who are interested in a particular style will find your logos in one place.
You might wish to review how you present your logos. It looks a bit sloppy, something that you would throw together in 1-2 minutes. You’re a designer, so it matters how you present your work. Check how top sellers present their logos
Lower your prices until you get a couple of reviews
You can offer vector file with your $5 gig. This isn’t extra effort for you because you will create the vector file anyways. The same goes for high quality images.
