This one is aimed mostly at new sellers. Coming from 6 years of experience on fiverr, i would say being on the featured list or your gigs shown in the first page or what so ever has no real effect in your sales if you dont provide what you talk about. If you can provide the best quality of output with good honesty and the urge to do more, where you are currently positioned wont be an issue and sales will come in your way.
Effort, the need to do and honesty will be the key points. not a featured gig or not.
