Why showing BEST SELLER top of my gigs?

Hi Expert !
Can you tell me: Why showing BEST SELLER top of my gigs ?
I completed only three orders. Published four gigs: (1)virtual assistant,(2)social media marketing,(3)google top ranking, and (4)Classified ads posting.
Many days gap ! So, what is the benefit of BEST SELLER ?

Thanks every body for your valuable advice.
