Well, having many gigs does not guarantee you getting orders. You might want to check on a few things about your gigs, including your pricing strategy and gig description. Most of the time, buyers are looking for a seller who will give them an impression that they will deliver high quality work at a competitive rate. Additionally, your description plays a crucial role in your ranking. This means if your gig description is not optimised, you may fall short of clicks, hence no orders. I hope this information helps.
