Just a few things:
Remove: “I wanted to earn extra for some important thing I want to do, so I bring my transcription expertise to fiverr as well” because the buyer won’t care. Keep your gig description to things that are going to sell the gig.
What’s the difference between audio transcription and transcribe audio?
Do not offer unlimited revisions (3 or 5 is fine) don’t offer refund in your gig description. These things make you look inexperienced. You can’t hide the fact that you’re new to Fiverr, but you should look as if you have other experience.
remove:“So what are you waiting for Man/Woman/AI/Alien?”
The 20 hours thing is odd & there’s no way to measure it as 24 hours is the minimum gig time. Some people add an extra for 12 hours/16 hours etc. I wouldn’t make it part of the basic gig.
Other than that, be patient. Gigs in popular categories take a long time to get orders, if ever. I would recommend you having more gigs if you are trying to make money for something in particular.
