Actually, the list of buyer requests that you just can see depends upon the category of your gig. as an example, if you have got a t-shirt design gig, and you have got that gig within the t-shirt design category, you may only see buyer requests that are seeking t-shirt design services.
If you don’t see any buyer requests, that it's going to somewhat be the case that nobody has posted any new buyer requests for your gig category.
A word of recommendation , though: Don’t depend on buyer requests to be your only source of sales leads. specialise in promoting your gigs, and obtaining potential sales from other more direct sources. you're not planning to become successful on Fiverr by specializing in only buyer requests.
