I am a new seller in fiverr.com and i am doing web designing and error fixing. These days i’m waiting for my first order.
No seller is guaranteed sales here on Fiverr. Your Fiverr gigs are a business, you need to treat them as a business: market, promote, improve presentation, etc.
Patience is important, if buyers like your services they will order from you, if not, perhaps you need reassess your gig(s), or develop services people are looking for. Competition is intense, you need to find a way to stand out from the rest. Unfortunately, right now, you are not standing out from the competition.
Unless you’re doing something really bizarre, you should expect your first sales to come from other sources - advertise your skills (and fiverr) ot social media, etc.
Or you should really do something special that helps you stand out from the crowd.
Whatever you decide to do, I’m sure that it only gets easier with time
