I havent marketed outside of fievrr at all, not even once… and im the most popular gig in my category.
Im sure promoting ur gig on social network helps allot… but its not always needed if u provide a quality gig.
oh sorry, need to correct myself there; i did actually buy a gig from a fellow fiverr seller to have my gig marketed on Radio… it was a great gig and very well done, but didnt feel an increase in sales.
I have advertised one of my gigs in both twitter and on facebook and have had success with both. I suspect that it really makes a difference what your gig is about, because it is all about targeting the RIGHT audience.
