Took a week for me to get my first job and almost two months to get my second, I spent time researching my competition, their pricing, what they were offering, how they presented there product, and in the last two weeks I’ve recieved around 15-20 orders, so, I don’t know. You say you’ve prepared everything but for example, your gig covers look like they could’ve been done in PowerPoint, but the gig claims you’re using Photoshop.
On one of your gigs you start off by saying “I’m new to Fiverr”, why not start off with the experience you DO have, instead of the experience you don’t? You also mention “Hopefully I’ll be able to meet your needs”, but being hopeful isn’t going to get me the product I’d want as a buyer, it says to me you aren’t confident in what you’re selling.
Lastly, I believe there are tests you can take through the profile section for free to verify your knowledge, people can filter sellers based on this, and if you haven’t verified your knowledge then you aren’t going to show up. I took the time to verify my languages and customer service, and in the last two weeks I’ve noticed a very slight increase in impressions/clicks, whether or not it’s resulted in sales, I’m not sure, but it’s worth the effort. Not to mention that there are paid courses you could do for photography and design that at the end will give you badges through the Learn section of Fiverr, although I’m not sure how much this could improve sales.
All in all, I have to say there is so much more you could be doing to improve your odds if you really wanted to, but like many, don’t invest the time and expect immediate sales. Good luck!
