People who get sales the same day as they register or create their first gig here on Fiverr are extremely lucky. I was extremely fortunate to receive my first order within four days, and another few a week later, but I know that for many people the wait can be far longer.
The impressions you’ve received are a great start. It shows that you’re showing up in search results and that people are taking the time to look at your gig. Something to bare in mind though is that impressions do not equal purchases. I bet that, for a lot of people here on Fiverr, if not everyone, their impressions are higher than their rate for gigs purchased.
One thing you can do to try and get your first order is to look at your competitors. What are they doing? Don’t copy them, because that’s immoral and I’m pretty sure it’s against Fiverr’s TOS, but take inspiration from them. Look at their titles, descriptions, etc., and compare them to your own. What are you missing? Is there something you could be offering that they aren’t? That’s a good way to get ahead in Fiverr’s marketplace.
I hope this helps!
